Welcome to Area41 OSINT Switzerland CTF

What is this CTF?

There are 15 collectible cards going around the conference. Each version of a card contains a unique code that unlocks a corresponding challenge. To solve all the challenges, you'll need to collect all the different cards from other conference participants. Use your phone to scan the NFC tag contained in each card.

  • The challenge will be open until the end of the conference.
  • There will be prizes for the first three participants who solve all challenges.
  • This is a strictly OSINT CTF: no exploitation, no hacking tools required.

Good luck and have fun!
