Bring Your Own Vulnerable Device: The EDR Killer Economy

The report explains that EDR-killing tooling leveraging vulnerable signed drivers (BYOVD) has become a mature, marketized product sold and provisioned by ransomware operators to affiliates; multiple tracked tools (e.g., GentleKiller/AvNeutralizer/EDRKillShifter) abuse kernel access to terminate protected security processes, are resold or rented across competing gangs, and are supported by tiered pricing and centralized provisioning—significantly lowering the skill floor for attackers and forcing defenders to focus on behavioral/kernel-level defenses rather than static indicators.
