DYN ATTACKS

Millions of IoT Devices Launch Huge DDoS Attack

DDoS attacks are on the rise and DNS is the number one protocol used in amplification/reflection attacks according to latest security reports. The recent DDoS attacks on Dyn, a managed DNS provider , was a big one and clocked at a max of 1.2 Tbps. The effect? Several organizations whose DNS was hosted by Dyn experienced downtime and their their customers were not able to use their applications and services.

The source of the attack were millions of compromised “Internet of Things” (IoT) devices including CCTV cameras and digital video recorders. Most IoT devices are built for low cost and don’t come with out of the box security. It was not clear if the traffic sent to Dyn servers were junk traffic or a flood of legitimate DNS queries, but the attack rendered Dyn’s name servers unresponsive.
