Challenges

For this 3rd edition, it is once again our great pleasure to offer you challenges written by OSINT enthusiasts and professionals:

C'est vrai ça? | ONARP | OpenFacto | Oscar Zulu | OSINT-FR | OSINT4Fun | Projet FOX | Romain P. | Sofia Santos

  • You will discover a new challenge every day.
  • Badges will be awarded to participants based on their success. To receive them, you will need to have an account and have badges enabled.

Organisation

  • Only two people know the answers to the challenges and are therefore excluded from the game: Céline Girardeau and Alain Godon.
  • You can join the OSINT4Fun Discord server to chat with other players.
