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!
