In September 2016, Twitter, CNN, Spotify, and many others were knocked offline by the biggest DDoS attack in history. Today we know it by the name Mirai, but no one would have imagined at the time that this attack was coming from a herd of Internet of Things (IoT) devices cobbled together to form a botnet.
Mirai was discovered by MalwareMustDie researchers in August 2016 . Although it was not the first IoT malware to be discovered, it is certainly the most prominent.
