Intelligence Investigation Experience: People

Class Description

This course, taught by a member of the winning team at the DEFCON 28 and DEFCON 29 OSINT Search party, is designed to hone specifically in on the processes and tools used to perform “People Intelligence” or “People OSINT” in situations where investigators are seeking to find missing people, some of which do not want to be found. This focuses on validating the information discovered and using it to pivot to valuable information, in both a CTF setting (such as Trace Labs’ CTFs/OSINT Search Parties) and law enforcement.

This course is approved by TraceLabs

This course has evolved from a 4-hour course to a 6-hour course, and now to an 8-hour course. This LIVE Missing Persons OSINT course, approved by TraceLabs seeks to prepare Intelligence and True Crime enthusiasts and private investigators for techniques used to find missing people.

In brief, this course covers the following:

  • Social Media
  • Intelligence Processes and Cycles
  • TraceLabs categories
  • Case Studies
  • A simulated CTF where the class collaboratively works to try to find an actual missing person (The primary reason that this course is not ever recorded)

At the end of the course, you will participate in a Mini-CTF to apply the concepts you’ve learned in a collaborative and fun environment.

What People Are Saying About the Course

You may have heard the old saying: "Everyone wants to do OSINT until it's time to go do OSINT stuff". If that's not a saying, it should be. On the surface, Open Source Intelligence gathering sounds fun and super cool.

Picture this: You're sitting alone in your apartment. Lights dimmed. The glow from your laptop illuminates a face framed by a black hooded sweatshirt. Soon, secrets will reveal themselves to you. Truths never meant to be known. Fingers rest on your keyboard. You exhale. And begin typing in Google...."

And that's about as far as most people get on their OSINT journey.

OSINT collection is hard and is even harder to get started in when you have no idea where to begin. This is where Joe's Introduction to People OSINT course comes in.
