What it detects

This rule detects processes other than the legitimate Windows Biometric service host loading the Dell ControlVault libraries bcmbipdll.dll or BCMStorageAdapter.dll. The ReVault attack abuses ControlVault firmware vulnerabilities, and abnormal processes loading these libraries indicate exploitation attempts against the security co-processor. Such loads can lead to code execution and firmware-level persistence.
