Modern OSINT Tradecraft: Attribution, Analysis, and OPSEC

Lex Tungkasiri

Open Source Intelligence (OSINT) is often dismissed as “just Googling,” yet it has become one of the most powerful methods for collecting, correlating, and attributing information across public and semi-public sources. This presentation explores modern OSINT methodology through real-world examples, demonstrating how investigators pivot across social media, imagery, geospatial data, and other datasets to build attribution models and uncover relationships. Topics include geolocation, chronolocation, cross-platform identity correlation, cryptocurrency transaction analysis, AI-assisted investigative workflows, and common pitfalls such as false attribution and data poisoning. The session will also examine operational security, ethics, legality, and the privacy implications of modern intelligence gathering. In addition, the speaker will demonstrate a new open-source AI-powered OSINT platform designed to assist analysts with data triage, correlation, and investigative workflow automation, which will be released free to the community.
