- People-Centric OSINT: Social Media, Geolocation, and Digital Footprinting
Finding people using public data is one of the most common OSINT use cases. A comprehensive article by Narendar Battula outlines methodologies for collecting user information, including tools available in Kali Linux and real-world reconnaissance workflows. Key techniques include leveraging social media platforms, public records, and geolocation data to build detailed profiles.
For geospatial intelligence (GEOINT), Logan Woodward shares three essential tips: tailor your source to the location you are investigating, tailor your source to specific environmental features, and get more out of the source you use. A list of map resources is available via lnkd.in/dGST7Q25, providing investigators with satellite imagery, cadastral maps, and other geographic data sources.
Step‑by‑step guide for people-centric OSINT:
Step 1: Start with a full name and known location. Use search engines with advanced operators (e.g., "John Doe" London site:linkedin.com).
Step 2: Leverage social media search tools like Social-Searcher or Mention to find mentions across platforms.
Step 3: For geolocation, use resources like Google Earth, Sentinel Hub, or the map resources list provided by Woodward.
Step 4: Cross-reference findings with public records databases and people search engines.
Step 5: Document the digital footprint and analyze patterns (e.g., posting times, affiliations, relationships).
