Cybersecurity challenge 404 CTF

From May 10 to June 1, 2025 online, the Direction Générale de la Sécurité Extérieure (DGSE) and Télécom SudParis, in partnership with OVHcloud and VivaTech, are organizing the third edition of 404 CTF, a Capture The Flag challenge designed by our HackademINT cybersecurity club. This year's theme is sports.

Are you a student, a new technology professional, a hobbyist, a novice, a seasoned pro or an expert? For three weeks, whatever your level, put your skills to the test in this individual CTF. The winners will be rewarded at the Viva Technology trade show in June.

The competition attracted almost 3,000 participants at its 3rd edition in 2024. It illustrates the current partnership between the DGSE, Télécom SudParis and Institut Mines-Télécom in the field of digital sovereignty.

→ Registration is open and will remain so throughout the competition.
