About Crate-CTF:
Crate-CTF is an annual cybersecurity competition organized by the Swedish Defence Research Agency (FOI) in collaboration with the Swedish Armed Forces. This year’s event takes place Saturday, November 15, 2025, from 14:00 to 22:00, and offers 8 hours of hands-on hacking challenges in categories such as:
- Reversing – analyze binary code to extract secrets
- Exploitation – find and leverage vulnerabilities
- Web – attack and defend web applications
- Cryptography – break or understand ciphers
- OSINT – use open-source intelligence to find clues
The competition features dynamic scoring, meaning points depend on how many teams solve each challenge, the rarer the solve, the higher the score! All you need is a computer with a browser, and your favorite toolkit. After the CTF, we will have a sit down and go through all the challenges together.
