Publicly available data can paint a much clearer picture of our lives than most of us realize, and this episode takes a deeper look at how those tiny digital breadcrumbs like photos, records, searches, even the background of a Zoom call can be pieced together to reveal far more than we ever intended. To help break this down, I'm joined by Cynthia Hetherington, Founder and CEO of The Hetherington Group, a longtime leader in open-source intelligence. She also founded Osmosis, the global association and conference for OSINT professionals, and she oversees OSINT Academy, where her team trains investigators, analysts, and practitioners from all experience levels.

Cynthia shares how she started her career as a librarian who loved solving information puzzles and eventually became one of the earliest people applying internet research to real investigative work. She talks about the first wave of cybercrime in the 1990s, how she supported law enforcement before the web was even mainstream, and why publicly accessible data today is more powerful and more revealing than ever. We get into how OSINT actually works in practice, from identifying a location based on a sweatshirt logo to examining background objects in video calls. She also explains why the U.S. has fewer privacy protections than many assume, and how property records, social media posts, and online datasets combine to expose surprising amounts of personal information.

We also explore the growing role of AI in intelligence work. Cynthia breaks down how tools like ChatGPT can accelerate analysis but also produce hallucinations that investigators must rigorously verify, especially when the stakes are legal or security-related. She walks through common vulnerabilities people overlook, the low-hanging fruit you can remove online, and why your online exposure often comes from the people living in your home. Cynthia closes by offering practical advice to protect your digital footprint and resources for anyone curious about learning OSINT themselves. This is a fascinating look at how much of your life is already visible, and what you can do to safeguard the parts you'd rather keep private.
