Speaker: Mathy Vanhoef Mathy Vanhoef is a postdoctoral researcher at KU Leuven (Belgium). He finished his PhD on the security of WPA-TKIP, TLS, and RC4, in July 2016. His research interest is in computer security with a focus on wireless security (Wi-Fi), network protocols in general, the RC4 stream cipher, and software security (discovering and exploiting vulnerabilities). Currently he is researching how to automatically detect logical flaws in network protocol implementations. Mathy Vanhoef is a postdoctoral researcher at KU Leuven, where he performs research on streamciphers, discovered a new attack on RC4 that made it possible to exploit RC4 as used in TLS in practice (the RC4 NOMORE attack), and found the HEIST attack against TLS. He also focuses on wireless security, where he turns commodity wifi 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. Currently he is researching how to automatically fuzz network protocols, and detect *logical* flaws in implementations (e.g. downgrade attacks). Apart from research, he also 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.
