Overview

This weekend, I played HKCERT CTF 2022 upon invitation from Mystiz, member of team Black Bauhinia. The competition is mainly for Hong Kong players and we joined as an invitational team. Overall I had a great time solving many of the challenges and we ended up in the first place with a narrow margin.

Thanks to my teammates Utaha, ElleuchX1, and Piers for playing!

I decided to writeup some of the challenges that I found interesting.

Name	Difficulty	Solves
