Open-Source Intelligence (OSINT)

From Spycraft to Citizen Investigation

Open-source intelligence — OSINT — refers to information gathered from publicly available sources: social media posts, satellite imagery, corporate registries, flight tracking data, shipping records, court filings, and countless other databases. The term originated in military intelligence, where it was considered the least glamorous discipline. Today, it has become arguably the most transformative force in investigative journalism.

Bellingcat, founded by Eliot Higgins in 2014, demonstrated that a small team of online investigators could produce intelligence-grade analysis using only publicly available data. Their investigations identified the Russian military unit responsible for shooting down MH17, exposed the GRU agents who poisoned Sergei Skripal, and documented chemical weapons use in Syria — all without a single confidential source or classified document.

The OSINT Toolkit

Social media is the richest OSINT source. Soldiers post selfies revealing military positions. Officials share photos that leak sensitive information in the background. Protesters livestream events that authorities later deny occurred. The challenge is not finding data — it is filtering, verifying, and preserving it before it disappears.

Satellite imagery from Planet Labs, Maxar, and the European Space Agency's Sentinel program makes it possible to monitor troop movements, detect environmental destruction, and verify claims about construction or demolition. The Associated Press used satellite imagery to expose China's construction of detention facilities in Xinjiang.

Corporate and property registries reveal who owns what. Investigative consortiums like OCCRP trace shell companies, offshore accounts, and real estate holdings to expose corruption. Flight and ship tracking data from ADS-B Exchange and MarineTraffic has been used to track oligarch yachts, CIA rendition flights, and sanctions-busting oil shipments.

OSINT as a Civic Skill

You do not need to be a journalist to benefit from OSINT skills. When your local government claims a development project is on schedule, satellite imagery can verify it. When a company claims environmental compliance, public sensor data and regulatory filings tell the real story. When a social media post makes a dramatic claim, OSINT techniques let you check it yourself instead of waiting for a fact-checker.

The democratization of OSINT is one of the most significant shifts in the information landscape. Tools that were once available only to intelligence agencies are now accessible to anyone with an internet connection. This creates both opportunity and responsibility — the same techniques used to expose war crimes can be misused to dox individuals or fuel conspiracy theories.
