# STACK the Flags 2022

STACK the Flags is a 48-hour, online jeopardy-style Capture-the-Flag competition organised by GovTech’s Cyber Security Group.

I had fun playing this CTF casually with my friends, and trying out some interesting new categories like Cloud and IoT!

Unfortunately, some challenges were contributed by Hack The Box and writeups for these are embargoed. Here are the rest of the writeups for the more interesting challenges I solved!
