SSHowDowN IoT Attack – Daily Security Byte

Over the past few weeks, we learned about an Internet of Things (IoT) botnet that launched at least two huge distributed denial of service (DDoS) attacks. We also learned about the botnet software that attackers used to infect these devices. Now, we’re learning about an old SSH configuration flaw that allowed these attackers to bounce their malicious traffic off these insecure devices. Watch the video below to learn more about the SSHowDowN Proxy vulnerability affecting many IoT devices.

Show Note: I am attending Gartner’s ITExpo this week, so may not post videos as regularly as normal.
