What it detects

This rule flags process executions whose command line contains registry path and value fragments associated with disabling storage write-protection. Attackers may attempt to weaken storage safeguards to enable later destructive or extortion-related activity. The detection relies on Windows process creation telemetry and matches specific command-line substrings related to the relevant registry location and settings.
