Intro CTF 2025 by KITCTF

Snatch those flags right from our production lines to gain points in the intro edition of the KITCTFCTF.

Flag production will run from 13 November 2025, 20:00:00 CET to 11 December 2025, 19:00:00 CET.
Everyone can participate! This is a solo event but you can of course discuss your approach with friends and we will provide hints and support throughout the competition too. Just don't share complete solutions or flags. We're here to learn, after all!
The contest is a jeopardy-style CTF with challenges from the major categories and beginner-friendly to hard difficulty.

We will use the channel #introctf-25-ws on our Mattermost for communication (ask at our meeting or write a mail).
Each player should play on their own. Just create an account.
If you have a question or a problem, please reach out to us (e.g. if a seemingly valid flag gets rejected).
The flag format is KITCTF{.*} (only printable ASCII characters), unless specified otherwise in the challenge description.
We use mixed dynamic scoring. That means, challenges which are solved more often will be worth less points but half of their value is static. Every person that solves a challenge is awarded the same amount of points, the scores will be updated dynamically.

The following behavior is strictly prohibited:

Any behavior that affects the fairness of the contest.
Posting or sharing task solutions or flags.
Attacking the contest infrastructure or systems of organizers or other participants. Only the servers mentioned in challenge descriptions or resources are in scope.
Exploiting vulnerabilities in the contest infrastructure or purposefully breaking challenges for others. If you find such a vulnerability, congratulations, but please report it to us.
