Researchers from the GRAFO group and cybersecurity students organize the first Competitive CTF cybersecurity course.

During 12 weeks from October to December a cybersecurity course has been held, this course divided into 4 modules: Introduction and Cryptography, OSINT, Forensic Analysis and Steganography, Server Attacks and Web Exploitation, Reversing and Binary Exploitation.

More than a hundred students attended the first edition of the cybersecurity course related to CTFs, competitive. PhD students Raúl Martín Santamaría, Sergio Pérez Peló and Isaac Lozano Osorio collaborated in the organization of the course together with the cybersecurity students.
