OSINT stands for Open Source Intelligence. It is the process of collecting, evaluating, and analyzing publicly available information (from overt sources) to produce actionable intelligence.  What Counts as “Open Source”? •  Websites, social media, news articles, blogs •  Public records, government databases, court filings •  Satellite imagery, maps, geolocation data •  Academic papers, forums, leaked (but publicly accessible) data •  Videos, photos, metadata •  Company filings, job postings, WHOIS/domain data Key point: Everything must be legally and ethically accessible — no hacking, no unauthorized access. The OSINT Intelligence Cycle 1.  Requirements — Define what you need to know (e.g., “background on Person X” or “vulnerabilities in Company Y”). 2.  Collection — Gather raw data using search engines, tools, and manual techniques. 3.  Processing — Clean, organize, and filter the data. 4.  Analysis — Turn data into insights, verify sources, identify patterns. 5.  Dissemination — Report findings clearly (with sources cited). Popular Free / Widely Used OSINT Tools & Resources (2026) •  OSINT Framework — Tree-structured directory of hundreds of tools by category (username, email, domain, images, etc.). Excellent starting point.  •  theHarvester — Email, subdomain, and host enumeration. •  Maltego — Powerful link analysis and visualization (free community edition available). •  Google Dorks / Advanced Search Operators — Extremely effective for targeted searches. •  Shodan — Search engine for internet-connected devices. •  Censys, VirusTotal, urlscan.io, Have I Been Pwned •  WhatsMyName, BGPView, CentralOps, etc. •  IntelTechniques (Michael Bazzell’s site and books) — Gold standard for people-search and privacy-focused OSINT. Many professionals also use OSINT Industries, Recorded Future, or custom scripts/APIs. Common Techniques •  Passive reconnaissance (no direct contact with target) •  Metadata extraction (from PDFs, images, documents) •  Reverse image search (Google, Yandex, TinEye, etc.) •  Social media profiling and cross-referencing usernames •  Geolocation via photos, EXIF data, or public posts •  WHOIS, DNS history, and subdomain enumeration •  Boolean search operators and site-specific searches Who Uses OSINT? •  Law enforcement & intelligence agencies •  Cybersecurity / red teams / threat intelligence •  Journalists, investigators, recruiters •  Businesses (due diligence, competitor analysis) •  Individuals (personal security, genealogy, locating people) Ethical & Legal Note: Always respect privacy laws (GDPR, CCPA, etc.), terms of service, and avoid doxxing or harassment. Good OSINT includes source verification and bias awareness. Getting Started 1.  Visit osintframework.com and explore. 2.  Read Michael Bazzell’s OSINT Techniques book (latest edition). 3.  Practice on yourself or public figures using ethical targets.
