Understanding BYOVD Attacks and Mitigation Strategies

**Bring Your Own Vulnerable Driver (BYOVD)**: The report explains how attackers load legitimately signed but vulnerable drivers to gain kernel-level privileges and bypass security controls, recounts multiple historical and recent abuses by ransomware gangs and APTs (including RobbinHood, Lazarus, Scattered Spider, BlackByte and Spyboy/Terminator), outlines mitigations such as patching, driver whitelisting and Microsoft’s vulnerable driver blocklist, and promotes Halcyon Kernel Guard and DXP as a more proactive, real-time detection and response solution.
