Start with a name, username, company, domain, image, property, or public record and learn to turn scattered clues into verified findings.

The Grey OSINT Manual is a practical 132-page guide to lawful OSINT, digital-footprint research, public records, business due diligence, and evidence-based investigation.

Inside, you’ll learn how to:

• Research usernames, domains, websites, images, documents, and archives
• Follow corporate records, ownership structures, contracts, filings, and public asset indicators
• Separate facts from inference, coincidence, and false matches
• Build timelines, entity maps, confidence assessments, and professional reports

Includes 22 chapters, five fictional case files, eight appendices, investigation checklists, worksheets, a dossier template, and 58 official-source references.

Ideal for journalists, researchers, investigators, compliance professionals, business owners, investors, cybersecurity professionals, and responsible beginners.

This is not a hacking, stalking, doxxing, or unauthorized-access guide. Every method uses public information, official records, and lawful research. Laws and record access vary by jurisdiction; this book is educational and not legal advice.
