‘HeadCrab’ Malware Variants Commandeer Thousands of Servers

At the Black Hat Europe 2023 conference, researchers revealed that a new variant of the HeadCrab malware has infected around 1,100 servers, adding to the 1,200 servers already compromised by the first variant. The malware gives access to the root of Redis open source servers, making it highly invasive. The new variant even features encryption for the command and control infrastructure. Created by an anonymous individual known as Ice9, the malware carries out cryptomining without noticeably reducing server performance.
