Building Local Knowledge Graphs for OSINT
Donald Pellegrino
Recon Village @ DEF CON 33 · Day 1 · Recon Village
In this insightful Recon Village talk, Dr. Donald Pellegrino, a seasoned expert with over two decades of research and development experience in information science, presented a robust methodology for **Open Source Intelligence (OSINT)** investigations. Titled "Building Local Knowledge Graphs for OSINT: Bypassing Rate Limits and Maintaining OBSAC," the presentation delved into a practical solution leveraging **knowledge graph** technology, specifically **Resource Description Framework (RDF)**, to construct queryable, offline OSINT repositories. This approach addresses critical challenges faced by modern OSINT analysts, including overcoming API **rate limits** and preserving **operational security (OBSAC)** by minimizing direct interaction with external services.

Competent integration of RDF/ontologies with local LLMs for OSINT workflows — the OBSAC framing is legitimate and the Graph RAG angle is practically useful. But this is applied methodology, not novel research: RDF triple stores, FOAF, SPARQL, and RAG are all established; the contribution is wiring them together sensibly for an OSINT context, which is useful but not groundbreaking.
