# FCSC 2022

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:

* [httpd (pwn)](/2022/fcsc_2022/httpd.md)
* [Hyper Packer (reverse)](/2022/fcsc_2022/hyper-packer.md)
* [Khal Hash (crypto)](/2022/fcsc_2022/khal-hash.md)
