picoCTF 2018 Writeup

This CTF was done with @pauxy and @StopDuckRoll

Special thanks to @LFlare for helping out with a few challenges!

Forensics writeups

Although it states that I may do some of the writeups for the forensics challenges, it's very unlikely it will ever be completed, mostly because those challenges were not solved by me, and I'm lazy. Pull requests are welcomed!
