What it detects

This rule detects loading of the HwRwDrv vulnerable driver, a bring-your-own-vulnerable-driver component observed in a Huntress-tracked Tiflux RMM malspam campaign to gain privileged kernel access. Attackers load this signed but vulnerable driver to tamper with protected processes and security tooling. Presence of this driver name is a strong indicator of BYOVD privilege escalation.
