What it detects

This rule detects service or driver loading of the renamed vulnerable GMER driver AGMT.sys or the rentdrv2 driver used by Agonizing Serpens (Agrius) to disable endpoint security through a bring-your-own-vulnerable-driver technique. The actor abuses signed but exploitable drivers to terminate EDR processes by PID which blinds defenses ahead of wiper deployment.
