Linux botnet abuses log4j to attack Arm, x86-based devices

A new Linux botnet, B1txor20, that targets Arm and 64-bit x86 systems shows log4j isn't going away any time soon.

We’re months into the disclosure of the log4j vulnerability and new attacks are still popping up. Cybersecurity researchers from Qihoo 360, a Chinese cybersecurity company, have just discovered a new Linux botnet, taking advantage of the flaw to distribute rootkits and steal sensitive data.  

They named the botnet B1txor20, and claim it uses the log4j vulnerability to target Linux Arm and 64-bit x86 systems. 

"In addition to traditional backdoor functions, B1txor20 also has functions such as opening a Socket5 proxy and remotely downloading and installing a rootkit," the researchers said.
