Hajime

Hajime is an IoT malware strain first discovered last October, and has compromised almost 300,000 devices, according to Kaspersky Lab. The botnet infects devices, which mostly include digital video recorders, webcams and routers, and blocks access to an array of ports.

Researchers say Hajime appears to be the work of a vigilante who does not want to use infected devices for bad purposes but instead take over smart devices before botnets like Mirai can.
