The JKU was one of 28 venues around the world that took part in the CCC. The programmers were divided into two categories - schools students and regular programmers - and between 1,000 and 2,000 participants took part in the contest. Team "Infoarenacoders" from Romania won the regular CCC. The challenge was to secure the 2020 C13 Summit Meeting in Moscow from attacks.

The large HS 1 hall at the JKU was full of enthusiastic programmers.  Team "Katalysatoren" came in ahead of team "s3n0wfall" and the duo "CCC Team". But the most important thing was that many young, talented programmers were able test and show off their skills and abilities using various technologies and platforms while having a great time.
