What it detects

This rule flags process creation events where the executed image path ends with BitLockerToGo.exe. BitLocker To Go is used to encrypt removable drives, so unexpected launches are worth investigating for potential abuse. It relies on Windows process creation telemetry that records the process image name or path.
