BYOVD Attacks: How Attackers Turn Signed Drivers Against Your EDR
Threat actors exploit vulnerable but legitimately signed drivers to bypass endpoint detection and response (EDR) controls, achieving kernel-level execution for malware deployment and persistence. This technique, known as bring your own vulnerable driver (BYOVD), leverages the trust placed in signed code to circumvent security protections.
Why it matters: Security teams relying on EDR to detect kernel-level threats face exposure when attackers abuse signed drivers; defenders should monitor for suspicious driver loading and review EDR capabilities against BYOVD techniques.
