This year, I participated in the Flare-On challenge organized by the FLARE team from Mandiant Google.
In total, 11 challenges of reverse engineering with increasing difficulty were to be solved. I did managed to resolve them all and as there was not a lot of activity on this blog recently, I pushed myself to put together some write-ups.
A few weeks ago, I participated in the France CyberSecurity Challenge (or FCSC in short); a Jeopardy CTF organized by the National Cybersecurity Agency of France (ANSSI) to select the french team that will participate to the European Cybersecurity Challenge (ECSC) at the end of 2020.
Among the challenges proposed (crypto, reverse, pwn, web, forensic, hardware), I really liked doing one of the reverse track named keykoolol.
We, once again, participated in the NorthSec competition. This article is about the DOOM challenge which was pretty interesting as you had to validate it at the VR station. @actgardner already made a write-up that you can find here. I wanted to complete it and show another solution that icecr4ck and I came up with.
Pour la deuxième année consécutive, Thales et Airbus ont organisé un CTF à destination des étudiants européens: le challenge ECW. Tout comme l’année dernière, celui-ci est séparé en une épreuve qualificative individuelle (CTF Jeopardy classique) et une phase finale par équipe avec un format Attaque/Défense.
