Summary
🤩
RockstarMathy Vanhoef is a security researcher and engineer with 14 years of experience focused on network and system security, especially wireless protocols and applied cryptography. He investigates real-world implementations across the full network stack, uncovering critical vulnerabilities (KRACK, Dragonblood, FragAttacks) and driving practical defenses that have been standardized in IEEE 802.11 for Wi‑Fi 7. Mathy blends offensive testing—contributing exploits and testing tools on GitHub—with standards collaboration and industry partnerships (Intel, Broadcom, Qualcomm, Huawei) to move fixes from proof-of-concept to mandatory deployments. His work spans TLS/HTTPS/VPN analyses as well as Wi‑Fi firmware and hostapd modifications to enable rigorous testing. Awarded repeatedly for real-world impact and cryptographic attacks, he pairs academic rigor with hands-on engineering to improve privacy, authentication, and resilience in deployed systems. Based in Brussels, he maintains an up-to-date publication and tools portfolio that emphasizes reproducible research and practical mitigations.
