CTF Rules/FAQs

CTF FAQs

The event is a ‘Capture The Flag’ (CTF) event, in which teams try to complete as many challenges as they can, completing a challenge earns the team a flag which scores the team points. The team with the most points at the end of the day is the winner.

As well as the honor of being crowned Irish Colleges Cyber-Security Champions, we give out over 3,000 euro in prizes each year across all categories, all thanks to our generous sponsors. This includes prizes for the top teams in each category and spot prizes.

To be eligible to win the main colleges prizes, all team members must be current students from the same Irish/NI college. Current student cards will have to be produced as proof of team eligibility, to collect prizes.

Everyone on the day competes against other teams in one of two categories: ‘College Teams’ or ‘Non-College Teams’.

College Teams: are defined as a team consisting of current students all from the same Irish/NI college.

Non-College Teams: includes everyone else. (non colleges students, industry professional, mixed college teams, etc.)

Only ‘College teams’ are eligible for the main prizes, but there will be prizes for the top team in the non-colleges category, and chances of spot prizes for everyone.

Each team can have a maximum of 4 members, no additional outside help is permitted.

You can compete on smaller teams or on your own, but why would you? It’s more fun in a team!

You can expect about 50 challenges on the day with a similar number of challenges in each of the following categories:

  • Web
  • Forensics
  • Crypto
  • Coding
  • Reversing
  • Exploit
  • Recon
  • Trivia
  • Pot Luck
  • Walk-about¬† (involves getting out of your chair such as lock picking, treasure hunts etc.)

Absolutely not! Any sharing or trading of answers will disqualify all teams involved.

Trading flags or asking other teams for help is completely against the nature of the event, and ruins the fun for everyone.

Each year we choose a theme for our event from Fr. Ted to Super heroes. Teams are encouraged to come in fancy dress. This year’s theme is ‘Horror!’.

Teams who come in costume (entire teams) will receive a bonus 200 points, and will likely get more spot prizes and have more fun!

You need to bring your own laptops and extension cables. While we try to provide WiFi for everyone we always recommend having access to your own internet hot-spot, through your phone or similar, and don’t rely on the venue WiFi. You’ve been warned.

The best training is taking part in CTF’s the next events are BSides Dublin and also Hack Trinity CTF.
