Gábor obtained his M.Sc. diploma in computer science in 2011 and earned his Ph.D. degree in 2015 from the Budapest University of Technology and Economics (BME). He did research in the CrySyS Lab together with prof. Levente Buttyán, but completed internships at iSecLab at Eurecom, France and TU Wien, Austria, too. He was one of the key members of the Duqu, Flame, Miniduke and Teamspy investigation teams.
He founded and coordinates CrySyS Student Core, which is an invite-only group of exceptionally talented students from BME who are interested in system security. This group gave birth to the !SpamAndHex CTF team, which became one of the best teams in the world in a few years. He co-founded a spin-off called Ukatemi Technologies with some of his colleagues from the CrySyS Lab in December 2012 to mitigate current targeted attacks. He also co-founded avatao to build a cloud-based virtual lab to host and share IT security exercises.
