What it detects

This rule flags loading of the intentionally vulnerable Windows kernel driver HEVD.sys by matching the loaded image path and specific IMPhash values. Loading this driver is notable because it provides kernel-level functionality that can be leveraged for privilege escalation and other impacts. The detection relies on Windows driver load telemetry that includes the loaded image name/path and its hash (IMPhASH).
