Security researchers discovered a new IoT botnet that is in a league superior to the Mirai variants that rise and fall on a daily basis. The developers of the botnet seek wide coverage and for this purpose they created binaries for multiple CPU architectures, tailoring the malware for stealth and persistence. Communications with the command and control (C2) servers is encrypted and capabilities include exfiltration and, command execution. The malware has been active since at least December 2017 and it targets devices on several CPU architectures: like MIPS, x86, x64, PowerPC, and SuperH.
