What it detects
This rule detects a process launched with an argv0 spoofed to resemble a kernel worker thread such as a bracketed raid5wq name which the GSOCKET tooling uses to hide its reverse connectivity on Linux hosts. Adversaries masquerade as kernel threads to blend into process listings and evade casual inspection.
