Last weekend, my CTF team hosted our first capture the flag competition. I was involved in creating several of the web challenges, with the rest of them being created by my teammate, Bryce. I’ve selected the 4 that I was involved in to create writeups for.
picoCTF 2021 was held between March 16th and 30th. Overall, there were quite a few interesting and fun problems. I’ve selected two of the problems that stood out: Some Assembly Required 4 and BitHug.
DMOJ CTF ‘21 was a CTF that I created for fun on the DMOJ programming platform. It consisted of 22 challenges that ranged from beginner to intermediate difficulty. I want to highlight one of the problems that I developed, which teaches a lesson about proper authentication mechanisms.
