Security News > 2022 > December > Microsoft warns of new Minecraft DDoS malware infecting Windows, Linux

A new cross-platform malware botnet named 'MCCrash' is infecting Windows, Linux, and IoT devices to conduct distributed denial of service attacks on Minecraft servers.

"Our analysis of the DDoS botnet revealed functionalities specifically designed to target private Minecraft Java servers using crafted packets, most likely as a service sold on forums or darknet sites," explains the new report by Microsoft.

Minecraft servers are often targets of DDoS attacks, whether to grief players on the server or as part of an extortion demand.

In October 2022, Cloudflare reported mitigating a record-breaking 2.5 Tbbs DDoS attack targeting Wynncraft, one of the largest Minecraft servers in the world.

"The botnet's spreading mechanism makes it a unique threat, because while the malware can be removed from the infected source PC, it could persist on unmanaged IoT devices in the network and continue to operate as part of the botnet." - Microsoft.

Most of the above commands specialize in DDoS attacks on Minecraft servers, with 'ATTACK MCCRASH' being the most notable due to using a novel method to crash the target server.
