Rules for N0PSctf

For the smooth functioning of this platform, the competition, and for the comfort of all participants, we kindly request you to carefully read and adhere to these rules.

Operation :

This competition is a CTF (Capture The Flag). It will take place from May 31st, 2025 starting at 10AM and concluding on June 1st, 2025 10PM (CEST). The goal is to solve cybersecurity challenges across various categories. Validating a challenge involves retrieving a string of characters called a flag and submitting it on the platform to earn associated points.

General Rules :

  • Brute-forcing the validation form is strictly prohibited.
  • Using any form of automated tool to validate challenges is strictly prohibited and unnecessary.
  • Any form of attack on this platform (ctf.nops.re and nops.re) is strictly prohibited.
  • Generally, the attackable scope is delimited by the links and services provided in the challenge statements, including their subdomains. Any other subdomain is off-limits and cannot be attacked.
  • The practice of flag hoarding, which involves holding onto found flags without submitting them on the platform, is strictly prohibited.
  • Sharing hints, flags, or any form of assistance with another participant or publicly is strictly prohibited.

Participation :

N0PSctf is dedicated to all levels, from curious beginners to CTF experts. Participation is strictly personal, limited to one account per individual. It is strictly prohibited to assist each other or share flags.

Teams are limited to a maximum of 3 participants.

If you encounter any issues with the competition or your account, you have two ways to contact support. The preferred method is to join our Discord server and address the admins. This allows you to stay informed in real-time of any issues or updates that may arise and to check if your question has already been asked and answered. If you prefer not to use Discord, you can email us at info@nops.re, and we will respond as soon as possible.
