Mathy Vanhoef is a PhD researcher at KU Leuven, where he performs research on streamciphers, and discovered a new attack on RC4 that made it possible to exploit RC4 as used in TLS in practice (the RC4 NOMORE attack). He also focuses on wireless security, where he turns commodity Wi-Fi cards into state-of-the-art jammers, defeats MAC address randomization, and breaks protocols like WPA-TKIP. He also did research on information flow security to assure cookies don't fall in the hands of malicious individuals. Apart from research, he knows a thing or two about low-level security, reverse engineering, and binary exploitation. He regularly participates in CTFs with KU Leuven's HacknamStyle CTF team.
