What’s a CTF?

A Capture the Flag (CTF) is a competition where people work in teams to find a password, called a “flag,” in as many challenges as they can.

Each challenge involves different skillsets, and you often learn something new along the way. Finding the flag can involve scouring the internet for clues, looking at hidden parts of files, tricking a website into revealing the flag, or manipulating computer memory to fish it out.

We host a CTF every spring. Anyone around the world can compete, and no experience is required. We’re also looking for challenge developers. If you’re interested in participating or helping, join our Discord server and let us know!
