What is picoCTF?

picoCTF is a computer security game targeted at middle and high school students. The game consists of a series of challenges centered around a unique storyline where participants must reverse engineer, break, hack, decrypt, or do whatever it takes to solve the challenge. The challenges are all set up with the intent of being hacked, making it an excellent, legal way to get hands-on experience. Read more on the About page.

picoCTF 2014 is over, you can still play for fun!

Registration works differently for picoCTF 2014 than for picoCTF 2013. This year, rather than having a single team account shared by everyone, each participant needs to create an individual account and then either create a team or join an existing one.

Here's how to register your team:

  1. One member of your team creates a new team choosing a Team Name and Team Passphrase.
  2. The team creater shares the Team Name and Passphrase with other members of the team.
  3. All other team members register and choose "Join an Existing Team", providing the Team Name and Passphrase.

You can add new members to your team at any time, even after the competition starts.

*While your password should be kept a secret and only used by you, your Team Passphrase is shared with the other members of your team. If you forget your Team Passphrase, it will be displayed on the "Team" page after you log in.

Teacher Accounts are a new feature for picoCTF 2014. Check out the Teachers page for more information.

Note that while Teacher Accounts can solve challenges during the competition, they do not appear on the public scoreboard.
