Today I came across this story from that looks to Security researchers that have discovered a new type of IoT botnet bypass firewall known as DoubleDoor, which can bypass firewalls and modem security using two backdoor vulnerabilities.
IoT devices remain the privileged target of cybercriminals and cyber attackers targeting so-called smart objects have seen rapid growth. Security researchers at NewSky Security (NewSky Security) have uncovered a new IoT botnet called DoubleDoor that can bypass firewalls and modem security with two backdoor vulnerabilities.
