Call For Challenges (C4C) is an opportunity for the community to contribute Capture The Flag (CTF) challenges that may be selected to compose events we participate in that include this modality.
- Participants are encouraged to submit original and creative CTF challenges in various categories, such as web, pwn, reverse engineering, etc.
- Submitted challenges will be reviewed by the organizing team to ensure they meet quality and relevance criteria.
- Selected challenges will be included in the CTF event or platform so participants can solve and enjoy them.
- Contributors of selected challenges will be recognized and properly credited.
- We count on the honesty of all community members who wish to submit challenges in order to have a fair and well-being environment for everyone.
We are currently accepting submissions for the following challenges (but not limited too), just click the link below to know how to submit:
Q: Who can submit challenges?
A: Anyone in the community with an interest in creating CTF challenges can submit.
Q: Can I submit challenges in multiple categories?
A: Yes, you can submit challenges in different categories, as long as they meet the submission guidelines.
Q: How many challenges can I submit?

Q: Can I submit challenges that have been used in other CTF events?

Q: How will we ensure that solving a challenge does not affect the CTF result?
A: Submitted challenges will receive a substantially lower score than that assigned to challenges created by the event team. This measure aims to ensure that, in case the solution of a challenge is disclosed or shared with CTF participants, its impact on the overall event result is minimized. In addition, we trust in the integrity of the community and participants who submit challenges. Our goal is to foster an environment of fairness and honesty, where community contribution is genuinely valued. Call For Challenges (C4C) was designed to encourage greater community participation, promoting the spirit of collaboration and rejecting any forms of inequality or dishonor in our community.
Q: How will the challenge score be defined?
A: The score of approved challenges will be determined by the event team. Each challenge will be evaluated based on its complexity, originality, and contribution to CTF diversity. The event team will assign an appropriate score to each approved challenge, taking into account various factors.
Q: What is the flag format?
A: Our flags have the following format HIK + SOME TEXT + MD5 HASH OF THE FLAG. E.g.: HIK_EASY_REVERSE_CHALLENGE_c22062e7a20164b9b89b38527b4e7f82
