KmsdBot was a newly found cryptocurrency mining botnet killed by accident by Akamai’s crew of researchers whereas researching on KmsdBot. In line with researchers, a syntax error triggered it to cease sending instructions, which destroyed the botnet.
What’s KmsdBot?
Named by Akamai Safety Intelligence Response Staff (SIRT) in November 2022, KmsdBot is was a crypto mining botnet outfitted with command-and-control skills. It contaminated victims by exploiting weak credentials and SSH through brute pressure.
The Akamai crew assessed and reported on the botnet after certainly one of its honeypots acquired contaminated.

Incident Particulars
In a weblog submit, Larry W. Cashdollar, a researcher at Akamai, the instructions despatched to the botnet whereas assessing its operational mechanism inside a managed setting mistakenly led to the malware’s neutralization.
After a single “improperly formatted command,” Cashdollar explains, the bot stopped sending any command. This could possibly be attainable due to the absence of an inside error-checking characteristic constructed into its supply code to confirm the incoming instructions.
So, any instruction given with no area between the port and the goal web site triggered the Go binary on the contaminated system to crash solely and cease speaking with its C2 server. Therefore, this killed the botnet.
For the reason that botnet doesn’t characteristic a persistence mechanism, the malware operators might want to re-infect the units as soon as once more and rebuild your entire infrastructure from scratch.
“This botnet has been going after some very giant luxurious manufacturers and gaming firms, and but, with one failed command it can’t proceed. It is a sturdy instance of the fickle nature of know-how and the way even the exploiter might be exploited by it,” Cashdollar defined.
