What it detects

This rule detects loading of the ThrottleStop vulnerable driver including the renamed ThrottleBlood.sys variant used in a Bring Your Own Vulnerable Driver attack to terminate security products. The driver exposes a device that lets an unprivileged process kill protected antivirus and EDR processes such as MsMpEng and SentinelAgent. Loading this kernel driver on a server or workstation with no ThrottleStop application present is highly suspicious.
