54 EDR Killers Use BYOVD to Exploit 34 Signed Vulnerable Drivers and Disable Security

ESET analysis reveals that many EDR-killer tools—specialized utilities used to disable endpoint detection and response before ransomware deployment—rely heavily on BYOVD (bring your own vulnerable driver) techniques, abusing dozens of legitimate signed drivers to achieve kernel-level access and neutralize security products; the report outlines developer/actor types, tool categories (script-based, anti-rootkit, driverless), and urges layered defenses and driver-blocking to mitigate the threat.
