PQ-REACT at the CyberWave 2026 of the AGH University of Kraków

In March 2026, the Faculty of Computer Science, Electronics, and Telecommunications at AGH University of Science and Technology in Kraków hosted the CyberWave 2026 student conference. Founded by students and staff, CyberWave aims to bring together the academic community, ambitious students, and IT industry professionals, with this year’s edition focusing on artificial intelligence, cybersecurity, and telecommunications. During the conference, the PQ-REACT partners from AGH organised a dedicated Capture the Flag (CTF) competition for students. They prepared several challenges with hidden flags, including tasks such as computing vectors related to PQC algorithms, correcting the implemented quantum algorithm in the Qrisp environment, and working with a hash-based digital signature. There was also one task that involved finding a flag hidden in a graphic file, which was the PQ-REACT project logo.

We invite you to try and find the hidden flag inside the PQ-REACT logo below!
