404 CTF - Edition 2024
The 404 CTF is France’s largest cybersecurity competition. It is organized jointly by the DGSE, Télécom SudParis, HackademINT, OVHcloud and Viva Technology. The 2024 edition took place from April 20 to May 12 2024 and gathered about 3800 competitors around 72 challenges designed by HackademINT. Learn more on the 404 CTF’s website or on the repository.
AI and Quantum Challenges
For the 2024 edition, I’ve created Quantum and AI challenges to introduce participants to these two fantastic worlds!
I started with an introduction to quantum algorithms based on the framework of the French start-up Quandela, which uses photonics. This was particularly well suited to talking about Quantum Key Distribution, a quantum communication protocol that is very interesting from a cyber security point of view. I also took the opportunity to show them that you can also have fun reverse engineering quantum circuits, and this time no assembly involved I swear :).
I then took a specific area of AI attacks, model poisoning, and decided to turn it into a suite of challenges. Unfortunately I didn’t have time to release my two difficult challenges, which were really nice :(, but there’s still an introduction followed by two small beginner challenges.
