What is Mirai botnet?
Mirai is a self-spreading malware which targets internet connected IoT devices such as smart TVs, CCT cameras, routers and other home appliances. It primarily targets the internet connected systems running Linux OS to turn them to remotely controlled “bots”. These bots are then used to launch large-scale network attacks. Mirai was first identified in DDoS attack on Krebs on Security website on 20 September 2016. This malware gained public attention after the recent historic DDoS attack on Domain Name System(DNS) provider Dyn. Cyber investigation revealed that 10 million Internet of Things were used to shoot this DDoS attack. Launching a DDoS attack is a painstaking task as it requires a careful programming and millions of machines under single control. But with Mirai, a program written in C language, it is quite easy to launch a DDoS attack with the help of minimal requirement.
