CrySyS SecChallenge 2020

The CrySyS Security Challenge is a Capture-the-Flag (CTF) competition organized by the CrySyS Lab of the Budapest University of Technology and Economics for computer science and electrical engineering students in Hungary. The Security Challenge usually spans over a period of 2 weeks, during which students can solve challenges from different sub-domains of IT security. The Security Challenge runs on the avatao.com on-line platform for IT security exercises, hence, participants can access the challenges remotely. Best performing students from the Budapest University of Technology and Economics will be invited to the CrySyS Student Core.
