This site offers educational and royalty-free resources in the field of OSINT – Open Source Intelligence. These resources are categorized into five levels of difficulty and divided across seven main objectives:
- OSINF (Open Source Information) : the basis of all challenges.
- ANALYSIS: when the pivots and links between the answer elements require in-depth analysis.
- FININT: related to financial investigations.
- GEOINT: anything related to geolocation.
- IMINT: everything involving image analysis (e.g., EXIF).
- SIGINT: when data processing is necessary.
- SOCMINT: everything involving social media analysis.
- OTHERS: anything not specifically covered by the previous categories, or which doesn't fit into the others, like /CLOCHINT, highlighted by Oscar Zulu.
The expected answers are available freely on the Internet. All necessary clues to find the correct answer are provided in the illustrations and descriptions. It’s up to you to identify and carefully analyze them. Sometimes the solutions may be detailed and also provide additional information.
