S2G CTF

Under no circumstances is it allowed to attack the CTF infrastructure!
None of the challenges require brute forcing servers. Do not perform brute force attacks on any of the CTF services unless specifically permitted by the challenge.
To solve a challenge, you will have to find a flag. Most challenges will have a flag that looks like S2G{...}
Each challenge has a given number of points, but the exact score depends on how many people manage to solve the challenge. For each person that solves the challenge, the score value of that challenge will decrease.
