Threat analysts have spotted a new variant of the BotenaGo botnet malware, and it's the stealthiest seen so far, running undetected by any anti-virus engine.
BotenaGo is a relatively new malware written in Golang, Google's open-source programming language.
Researchers at Nozomi Networks Labs have recently discovered a new variant of BotenaGo that appears to have derived from the leaked source code.
It appears that there is a substantial number of unpatched Lilin DVR devices out there to make sense for new botnet malware authors to target it exclusively.
Another difference between the Lillin scanner and the original BotenaGo is that the former relies on an external mass-scanning tool to form IP address lists of exploitable devices.
Still, it's an interesting new botnet project that proves how easy it is for malware authors to build completely stealthy botnets out of known, documented code.
