The HackSys Extreme Vulnerable Driver (HEVD) is a Windows Kernel driver that is intentionally vulnerable. It has been developed for security researchers and enthusiasts to improve their skills in kernel-level exploitation.

HEVD offers a range of vulnerabilities, from simple stack buffer overflows to more complex issues such as use-after-free, pool buffer overflows, and race conditions. This allows researchers to explore exploitation techniques for each implemented vulnerability.
