HackSys Extreme Vulnerable Driver (HEVD) is a Windows kernel driver specifically created with intentional security vulnerabilities for educational and research purposes. The driver contains various types of vulnerabilities including: - Stack buffer overflows - Use-after-free conditions - Race conditions - Other kernel-level security flaws HEVD serves as a training platform for security researchers and enthusiasts to practice kernel exploitation techniques in a controlled environment. The driver provides hands-on experience with Windows kernel security concepts and vulnerability exploitation methods. The tool is designed to help users understand kernel-level attack vectors and develop skills in identifying and exploiting kernel vulnerabilities. It operates at the Windows kernel level, making it suitable for advanced security research and educational scenarios focused on system-level security testing.
