Linux Malware on Windows

In retrospect it should probably be obvious, but the Windows Subsystem for Linux was destined to be yet another vector for infection for Windows machines. It’s finally happened in the wild, and Black Lotus Labs has the scoop. The actual malware sample is a Python script compiled into an ELF binary, designed to run inside the WSL environment. From there, it makes calls out to the Windows API. The advantage of using WSL ..
