Each the executable and the DLL are distributed through ZIP archives that mimic installers for professional purposes like Malwarebytes (e.g., “malwarebytes-windows-github-io-6.98.5.zip”) and different applications.
WSL abused with out course of spawn
SpecterOps researcher Daniel Mayer has launched a beacon object file (BOF) – a compiled C program designed to run throughout the reminiscence of a post-exploitation agent like Cobalt Strike Beacon – that interacts with the Home windows Subsystem for Linux (WSL) by immediately invoking the WSL COM service, avoiding course of creation for “wsl.exe” fully and permitting operators to record all put in WSL distributions and execute arbitrary instructions on any WSL distribution that the BOF finds.
Advertisements push covert RAT installers
