What it detects

This rule identifies Windows command-line activity that uses WMIC to uninstall or terminate software associated with security products. Such behavior is commonly used by attackers to disable defenses and reduce detection or prevention capabilities. The detection relies on process creation command-line telemetry containing WMIC uninstall/terminate patterns and product-identifying strings (e.g., common AV/EDR vendor names or “Endpoint Security” related terms).
