So I was following along twitter and found out about the Stripe CTF challenge.
Basicly, you are given a bunch of Pentest type challenges and you are required to complete them to move forward.
Here I'll go over each challenge, and describe what I did to solve the puzzle.
Keep in mind, alot of those hours was sleep, work and weekends with the family ;)
You'll find my write ups some time after the CTF closes here: https://coolacid.net/stripe-ctf-aug-12
