BSidesSF 2024 Writeups: Turing Complete (Reversing / exploitation)

This is a write-up for turing-complete, turing-incomplete, and turing-incomplete64 from the BSides San Francisco 2024 CTF! turing-complete is a 101-level reversing challenge, and turing-incomplete is a much more difficult exploitation challenge with a very similar structure. turing-incomplete64 is a 64-bit version of turing-incomplete, which isn’t necessarily harder, but is different. Let’s look at the levels!
