What it detects

This rule flags execution of PrintBrm.exe when its command line includes the arguments '-f' and references a '.zip' file, indicating ZIP creation or extraction behavior. Attackers can use this LOLBin-like utility to package or extract files in a stealthy way, blending with legitimate Windows tooling. Detection relies on Windows process creation telemetry that includes the executable path/name and full command line.
