What it detects

Identifies cases where wmiprvse.exe loads wbem\wbemcomn.dll from the Windows System32 WMI directory. This file placement and subsequent DLL load can indicate an attempted WMI DLL hijack used for execution or lateral movement. The rule relies on image-load telemetry showing the specific loaded DLL and process image involved in the load.
