What it detects

This rule detects a kernel driver being loaded from a user profile temporary directory, matching the behavior of the EDRKillShifter loader which drops a vulnerable BYOVD driver with a randomized name into AppData Local Temp and starts it to disable security tooling. Loading a signed but vulnerable driver from a user writable temp path is highly unusual for legitimate software.
