OOO archive --- DEF CON CTF [ login ]

Welcome, hackers. This is a live, playable archive of DEF CON CTF challenges.

Brought to you by the Order of the Overflow, current host of DEF CON's official CTF.

The archive is in beta.

Challenges are not particularly malicious or dangerous, but they are vulnerable by design (that's the game!). Containers isolate them, but it's up to you to play safely.

We're archiving more challenges and appreciate issue reports and suggestions, including via DEF CON's discord (CTF area). Just be mindful that running the CTF is tough and has priority. General FAQ

If you ran a cool CTF and want to give a shot at archiving your challenges, ping us at team@oooverflow.io
