description: This rule identifies Windows processes where WMIC.exe is used to uninstall or remove an application by executing a command containing both "call" and "uninstall." Attackers may use this technique to eliminate installed software, including security tools, or to stage changes that hinder investigation. It relies on Windows process creation telemetry, matching the image/filename for WMIC.exe and correlating required command-line substrings.
