Born from the collaboration between the Direction Générale de la Sécurité Extérieure (DGSE, France's foreign intelligence agency) and Télécom SudParis, the 404 CTF celebrates a double anniversary : the BCRA (unoccupied France's secret service during WW2) is 80 years old, and its successor, the DGSE, is 40 years old.
During one month (05/16/22-06/10/22), you will face challenges created by HackademINT, the cybersecurity club of Télécom SudParis. Whatever your level, there will be a whole range of challenges in a large variety of categories waiting to be solved !

This CTF is made possible thanks to OVHcloud, which enables us to use its Public Cloud platforms and helps us with its technical expertise in order for you to have the best possible experience.

IMPORTANT : Please note that this CTF's challenges will be written in French only.
