UIUCTF 2021

UIUCTF is an annual Capture the Flag competition run by undergraduate students at the University of Illinois at Urbana-Champaign (UIUC).

Hello, Fawl here.

I typically don't publish writeups for CTFs - despite being the team reverse engineer, I don't believe I'm at a skilled enough that my writeups would be worth publishing.

This time, however, my teammate zeyu2001 encouraged me to publish writeups, given the selection of prize money available. As such, you'll find below writeups for four of the beginner challenges, three serious and one tongue-in-cheek. Given how reversing can be quite an intimidating topic, I've done my best to present the writeups in an accessible, tutorial-style fashion.

Hope you enjoy!
