id: 60d46fa2-baa2-4aab-be57-7b0ba7f73344
status: test
description: This rule identifies executions of wmic.exe where the command line includes the " group" argument. Querying local groups can help an attacker enumerate group names and potentially infer membership or permission-related information. The detection relies on Windows process creation telemetry, matching the executable name/path and the presence of the group-related command-line parameter.
