OSINT — Open-Source Intelligence — is the practice of gathering information from publicly available sources. No hacking, no secret access, no classified materials. Just knowing where to look and how to connect the dots.
Sources of OSINT:
- Social media — people voluntarily share an astonishing amount of information. Location data, relationships, habits, opinions, travel plans.
- Public records — corporate filings, court records, property records, patent databases. Governments publish more than most people realize.
- News and media — traditional journalism, local newspapers, industry publications.
- Satellite imagery — Google Earth, Sentinel Hub, commercial providers. You can track construction, troop movements, environmental changes from your laptop.
- Academic papers — research publications reveal technical capabilities, institutional knowledge, and future directions.
- Web archives — the Wayback Machine and cached pages preserve information even after it’s been deleted.
- Technical data — DNS records, WHOIS data, network information, exposed databases.
Use cases:
- Journalism — investigative reporters use OSINT to verify claims, identify sources, and uncover stories
- Business intelligence — understanding competitors, markets, and potential partners
- Security — threat assessment, due diligence, vulnerability identification
- Research — academic and market research using publicly available data
- Verification — fact-checking claims, verifying identities, confirming events
The ethical dimension: just because information is public doesn’t mean every use of it is ethical. OSINT practitioners need to consider privacy, consent, and the potential consequences of their analysis.
The skill isn’t just collection — it’s analysis. Anyone can Google. The value is in connecting disparate pieces of information into actionable intelligence.
