What it detects

This rule detects loading of vulnerable kernel drivers abused by BlackByte to disable endpoint protection. BlackByte deployed the RtCore64 DBUtil_2_3 zamguard64 and gdrv vulnerable drivers to gain kernel-level code execution. Loading a known-vulnerable signed driver is a BYOVD technique that lets attackers terminate security products and tamper with the kernel.
