John TerBush, known as TheGumshoo on Twitter joins us to talk about his previous life as a private investigator and how he merged into the information security world. He, like so many others, was doing OSINT before we called it OSINT and he describes some of the locations and techniques. John is also a founding member of OSINT Curious and a course developer/instructor for the SANS SEC 487 and SEC 587 OSINT courses. He is also a threat researcher for Recorded Future. John has some great advice for getting started in the OSINT world and some fun stories of life on the job.
