Strategic tips for performing OSINT investigations

• How unique is a piece of information? And what does that mean?
  • How many people are named John Thompson vs. How many people have the phone number 555-666-7777?
• How can we link unique pieces of information together?
  • Cross-verify pieces of information.
  • Ex: Let's say sus. John Thompson (555-666-7777) lives at 123 Central Ave.
  • And sus. John H. Thompson ([email protected]) lives at 123 Central Ave. * It's fair to conclude that there MAY be a connection between these 2 Johns (this may be the same John).

• Look up a phone number (just google it - XXX YYY ZZZZ)
• Then look up the phone number PLUS a sus. name
• ex: Google "John Thompson XXX YYY ZZZZ"
• The difference in results from just searching the phone number can be quite a bit more specific (and more accurate)
• Keep in mind you can theoretically get some insanely granular results using this technique
• ex: What if we search their name, phone, and address? (ex: John Thompson XXX YYY ZZZZ 123 Central Ave.)
