This weekend (4 April 2015) take place the qualification round for "Nuit du Hack" CTF from 00:01 to 23:59. It was a Jeopardy CTF.

I have participated with the Zenk-Security team. At the end we got the 7th position and are qualified for the final which would be a Attack-Defense CTF in Paris in June.

I publish here the ones for the challenges I participated to and make a writeup of. All the writeup for this CTF are accessible here (in french).
