What it detects

This rule flags process creation of wmic.exe when invoked with the "qfe" option to query installed hotfix (patch) information. Attackers often use this kind of system inventory during enumeration to assess patch levels and identify potential vulnerabilities. The detection relies on Windows process creation telemetry, matching the wmic.exe executable and the presence of the " qfe" flag in the command line.
