Stealthy and Persistent Torii IoT Botnet Infects Devices via Telnet

[silversurfer]

Avast's Threat Intelligence Team has uncovered a new IoT botnet malware strain which spreads itself by attacking MIPS, ARM, x86, x64, PowerPC, and SuperH devices via the Telnet TCP/IP protocol.

As reported by Avast's security researchers, Torii is making rounds around the Internet since December 2017, but it wasn't detected until last week when the research team noticed a new botnet strain using higher grade infection techniques than Mirai.

Botnets are large collections of Internet-connected devices, sometimes hundreds of thousands, compromised by threat actors using malware designed to make them easy to control and used in DDoS attacks, spam campaigns, or data theft.
