OSINT Investigator is the intermediate certification of the Open Source Intelligence track. It trains you to conduct professional, reproducible and lawful investigations: framing the question and documenting evidence, protecting yourself with sound OPSEC, pivoting on usernames, emails, domains and web infrastructure, exploiting social networks and detecting coordinated behaviour, verifying images and videos through reverse search, geolocation and chronolocation, detecting manipulated and synthetic media, and delivering clear, sourced and responsible reports. The certification ends with a complete case study: unmasking a network of fraudulent online shops.
