I participated in the France Cyber Security Challenge 2022 (04/29 - 05/08) in the Senior category.

I managed to rank 1st place in the global ranking, among over 1500 participants. This was my ultimate goal after ranking 3rd in last year's competition, and I am very pleased to have managed to fulfill it.

I wrote a few write-ups, two that were required for the qualification, and a bonus one:
