OSINT Resources – Intelligence Gathering Tools

350+ OSINT tools and platforms across 33 categories. From username discovery (WhatsMyName, Sherlock) to threat intelligence (AlienVault OTX), geolocation (Google Maps, SunCalc), dark web research (Tor, Ahmia), blockchain analysis (Etherscan), and investigation frameworks (Maltego, Bellingcat). Includes free tools, commercial platforms, and open-source frameworks for comprehensive intelligence gathering.

• Always document your sources and maintain chain of custody for evidence.
• Use VMs or isolated environments when investigating potentially malicious infrastructure.
• Respect privacy laws and platform terms of service—OSINT doesn't mean illegal access.
• Verify information across multiple sources before drawing conclusions.
• Consider operational security: use VPNs, compartmentalized browsers, and pseudonymous accounts.
• Archive everything with timestamps—web content can disappear quickly.
• Join OSINT communities (r/OSINT, OSINT Curious, Trace Labs) to stay current with techniques.
