Open-source intelligence

Open-source intelligence (OSINT) is the practice of gathering and analyzing information from publicly available sources to produce actionable intelligence without relying on classified or covert collection. The field has been transformed by digital trace data: a modern OSINT analyst can track military movements through social media, identify financial fraud through blockchain records, or map supply chains through shipping logs. This abundance of observable data creates a new epistemic division of labor, where the limiting factor is not access but pattern recognition. OSINT functions as a distributed sensing layer for the modern world, though its vulnerability to information warfare and staged deception remains a critical weakness.
