πŸ‘€Lag and Crash 2023

In my honest opinion, this CTF contains a lot of guessy challenges and very little of those challenges that test your technical skills. My team, dad, still managed to take the top spot, just barely winning by 12 points.

Regardless, here are writeups for some of the challenges.
