The proliferation and availability of public information has increased with the evolution of its dissemination—from print, radio, and TV, to networked communications of the Internet Age. With the constant creation of digital document archives and the migration towards a paperless society, vast databases of information are continuously being generated. Collectively, these publicly available databases contain enough specific information to pose certain vulnerabilities. The actionable intelligence ascertained from these data sources is known as Open Source Intelligence (OSINT).
Numerous search techniques and applications exist to harvest data for OSINT purposes. Advanced operator use, social network searches, geospatial data aggregation, network traffic graphs, image specific searches, metadata extractors, and government databases, provide a wealth of useful data. Furthermore, applications such as FOCA, Maltego, and SearchDiggity, in addition to custom site API integration, yield powerful search queries with organized results.
Fluency in OSINT methodologies is essential for effective online reconnaissance, although a true mastery requires further mathematical investigation. The use of statistical correlation can often reveal hidden data relationships. Linkage attacks, inferential analysis, and deductive disclosure can exploit improperly sanitized data sets. These techniques can ultimately lead to data re-identification and de-anonymization, thus exposing personal information for exploitation.
