During last weekend, we host our first internal Capture the Flag competition, which we called OILCTF. Challenges are designed by members of CUHK CTF team g33z. This CTF aims to provide students some exercises as a follow-up of CTF Training Camp. After 48 hours, 0x000505AD won the 1st place with almost all challenges. Congrats!

There will be a review session on 26 March at SHB 833. We will discuss about solutions for each challenge. Welcome to join.
