Unsecured IoT devices are fueling bigger and bigger attacks
As the number of vulnerable or poorly secured IoT devices connected to the Internet continues to grow, so does the size of DDoS attacks. The more devices can be enslaved as part of IoT botnets, the more packets per second and bandwidth can be generated. This can also be combined with meditation and amplification techniques that are allowed by certain protocols.
In 2016, one of the Internet’s first IoT botnets, called Mirai, was responsible for an attack on French cloud computing company OVH that reached 620 Gbps, making it the largest DDoS attack on record up to that time. . That was a sign of things to come.
As companies began to move their infrastructure to the cloud and as the number of IoT botnets replicating Mirai increased, so did the magnitude of DDoS attacks. In 2018, GitHub’s repository was the target of a 1.3 Tbps DDoS attack, and in 2020 AWS dropped an attack that peaked at 2.3 Tbps. In 2021, Microsoft Azure was targeted by DDoS attacks rising to 3.47 Tbps.
