Mirai is a malware that turns networked devices running Linux into remotely controlled "bots" that can be used as part of a botnet in large-scale network attacks. The Mirai botnet was first found in August 2016 and has been used in some of the largest and most disruptive distributed denial of service attacks, including an attack on 20 September 2016 on computer security journalist Brian Krebs's website, an attack on French web host OVH, and the October, 2016 Dyn cyberattack.
