This is Mystiz, a security software engineer in Hong Kong 🇭🇰. I am better-known as a CTF player and I hack with Black Bauhinia (as the leader) and Shellphish. I like to struggle at crypto and reverse challenges, and sometime pulling my hair on misc. I am a three-time DEFCON finalist on 2019, 2020 and 2021, and occasionally a finalist for CODE BLUE CTF 2019.
