intermediate8 lessons

Open Source Intelligence (OSINT) is the discipline of collecting and analyzing publicly available information to produce actionable intelligence. This course takes you from the fundamentals of the intelligence cycle to practical reconnaissance techniques: footprinting organizations and people, domain and infrastructure OSINT, advanced search and Google Dorking, image geolocation, and automation with tools like Maltego, theHarvester, SpiderFoot, and recon-ng. All content is framed within a strictly ethical and legal approach: we use only public sources, respect privacy and applicable laws, and always prioritize the investigator's OPSEC.
