Wolv CTF 2024

Placement: #88/622

---

Thoughts:

Didn’t have too much time to do this CTF, especially since I was heading out of town midway through. But, I did manage to place 88th despite doing pretty much only two categories (beginner and crypto). Fun CTF overall, really liked some of the crypto challenges!
