Ask organizers if you are in doubt.


  • Competitors have to be physically present

  • During Ph0wn, for some specific challenges, participant may borrow equipment and smart devices. This equipment/device should be handled with care and returned in perfect working condition. In all cases, return promptly the item at the end of the CTF please (sometimes, it's our own, and it costs us!). Please discuss with the organizers if you have any question on what is permitted or not.
Participants must comply to the Code of Conduct. In particular, note it is strictly prohibited and subject to disqualification to:
  • Attack any machine other than the designated ones,
  • DoS Ph0wn CTF infrastructure or University,
  • Modify the scoreboard,
  • Intentionally prevent other teams from flagging.

Prize Attribution

This is a short explanation of how prizes are attributed.

At the end of the CTF, on Ph0wn's CTF scoreboard, the 3 teams with the highest score are identified and are entitled to a prize. In case the score is equal, the first team to reach the score is considered as first.
  • The first team is called to select 5 prizes among a pool of available prizes.
  • Then, the second team is called to select 5 prizes among the remaining prizes.
  • Finally, the third team is called to select 5 prizes among the remaining prizes.
  • If a team has less than 5 members, they still select 5 prizes :)

Prizes at Ph0wn are provided by our sponsors. Many thanks to them!
In case of insufficient prizes, those rules are subject to change.

This includes a warning, expulsion from the event with no refund (if applicable), or reporting their behavior to the local law enforcement.

As this is a security challenge, we would like to note that the hacks created during the Capture the Flag contest or the badges submitted to the Badge Contest are equally subject to the anti-harassment policy.

Sponsors, partners and authorized visitors are also subject to the anti-harassment policy. In particular, sponsors should not use sexualized images, activities, or other material. Sponsor representatives (including volunteers) should not use sexualized clothing/uniforms/costumes, or otherwise, create a sexualized environment. If you are being harassed or if you notice that someone else is being harassed, or have any other concerns, please contact any member of Ph0wn staff immediately. Ph0wn staff will be willing to help participants contact any local security or local law enforcement, provide escorts, or otherwise assist those experiencing harassment to feel safe for the duration of the event. We value your attendance.

Photography and video

Pictures or videos of individuals or small groups are forbidden without explicit permission. Screenshots of participant's laptops are also forbidden without explicit permission.

Pictures or videos of challenges or badges are welcome and authorized.

Some challenges or badges may use a camera. The camera will be clearly visible and identifiable. We expect people who do not want to be filmed not to walk in front of the camera, otherwise, it may be interpreted as an informal acknowledgment.
