Mastering OSINT and Skip Tracing: Finding People with Modern Techniques


In today’s digital landscape, the ability to locate individuals efficiently is a valuable skill for investigators, real estate professionals, and anyone needing to track down missing persons. Open Source Intelligence (OSINT) and skip tracing provide powerful methods to find people using publicly available information and advanced data analysis. After studying 30 books on these subjects, here are the most effective techniques and tools for modern skip tracing.


Understanding Skip Tracing and OSINT

Skip tracing involves locating individuals who are difficult to find, often due to evasion or outdated records. OSINT complements skip tracing by leveraging public and online data sources, turning scattered information into actionable intelligence. Books like Open Source Intelligence Techniques by Michael Bazzell emphasize the importance of using both traditional and digital resources.




Step 1: Laying the Groundwork with Basic Information

Before diving into advanced techniques, start by gathering all available details about the individual:

  • Full name (including aliases or maiden names)

  • Date of birth

  • Last known addresses and phone numbers

  • Email addresses and social media usernames

  • Known relatives and associates

Books like Secrets of a Skip Tracer highlight the importance of cross-referencing these details to establish patterns in a person’s movement and behavior.


Step 2: Leveraging Online Search Techniques

Google Dorking

Search engines are more powerful than most people realize. Using advanced search operators, also known as "Google Dorking," can reveal hidden information:

  • "John Doe" site:facebook.com – Finds exact matches of a person’s name on Facebook.

  • filetype:pdf "John Doe" – Searches for documents containing the person’s name.

  • intext:"John Doe" AND "Dallas, TX" – Narrows results to a specific location.

Books like Google Hacking for Penetration Testers explain how to refine search queries to uncover deeper information.

People Search Engines

Websites like Spokeo, BeenVerified, and TruePeopleSearch aggregate public records, phone numbers, and addresses. While they may not always be up to date, they provide a strong starting point.


Step 3: Social Media Intelligence (SOCMINT)

Social media accounts can reveal a person’s location, habits, and connections. Some essential strategies include:

  • Username Investigation: Books like Mastering OSINT Investigations recommend checking sites like Namechk and WhatsMyName to see where a username appears online.

  • Geolocation Analysis: Examining tagged locations in Instagram and Facebook posts can provide clues about a person’s whereabouts.

  • Friends and Family Connections: Even if the target has a private profile, their relatives or friends may post useful information.


Step 4: Mining Public Records and Databases

Many books stress the importance of official records when searching for individuals. Useful resources include:

  • Property Records: County assessor websites list property ownership details.

  • Court and Arrest Records: Some state and federal databases provide searchable records.

  • Business Registrations: Websites like OpenCorporates allow searches for LLCs and business filings associated with an individual.

Step 5: Phone Number and Email Tracking

Reverse phone lookup services and email tracking can uncover further details about a person’s identity:

  • Tools like OSINT Framework and PhoneInfoga analyze phone numbers for location and carrier information.

  • HaveIBeenPwned checks if an email has been compromised in a data breach, potentially revealing old usernames and linked accounts.

Step 6: Using Specialized OSINT Tools

Books like The OSINT Handbook introduce powerful software that helps automate investigations:

  • Maltego: Maps connections between people, organizations, and digital assets.

  • Spiderfoot: Automates OSINT gathering, scanning for emails, domains, and social media accounts.

  • Hunchly: Captures and archives web data for investigation purposes.

Step 7: Ethical and Legal Considerations

Every book reviewed emphasizes the importance of legal compliance and ethical responsibility in skip tracing. Data privacy laws, such as the GDPR and U.S. privacy regulations, dictate how information can be collected and used. Professionals must ensure they are accessing only publicly available and legally obtained data.




Conclusion: The Future of Finding People

Skip tracing and OSINT are rapidly evolving, with AI and machine learning playing a greater role in automating searches. While new tools continue to emerge, the fundamentals remain the same: persistence, creativity, and a deep understanding of available data sources. By combining traditional research with modern digital forensics, professionals can locate individuals quickly and efficiently while maintaining ethical standards.
