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