Are you a h@ck3r? Try Stripe’s Capture The Flag game, you’ll need to try and solve problems by exploiting vulnerabilities in their systems, but you’ll need to really hack at it! There are 6 levels, each with a password secured in some way. Use your madd hacking skills to advance to the next level.
I’m currently at level 4 but calling it a night. Here’s a few tips for challenges 1-3:
#1: google: system() exploit
#2: The basic authentication is NOT the challenge. The user and pass is the same that you used to SSH into level02.
#3: The deprecated function, it uses system() like in challenge #1 but the function is never called anywhere in the code. Oh and a buffer…
Plan to throw one [implementation] away; you will, anyhow.
