I'm excited to share that I've finally started to upload content to my research blog - ! My first post is a writeup of a critical unintended cryptographic security vulnerabilty we found during HITCON 2024 Qualifications, which we won 1st place 🔐🇹🇼

Halfway through Flare-On 11, and the challenges are 🔥 this year! I think this might be a great opportunity for a new series of posts in my research blog after the CTF wraps up👀 #FlareOn #CTF #ReverseEngineering
