OSINT - Location - Google ID trick

1 minute read

Just finished some HTB OSINT challenge.
You find someone’s location from their gmail address.
Interestingly enough, with a gmail address, you can get a Google ID (for the google ecosystem of apps) then use that to explicitly view all Google Maps reviews posted by that user ID.


  1. Goto hangouts.google.com
  2. In top left search bar, paste in their gmail address
  3. Once their gmail pops up in the little reactive results pane, r-click > Inspect.
  4. In the Developer pane that opens, look up a few lines for the hovercard-iod value. Copy it, that’s their Google ID.
  5. Goto google.com/maps/contrib/TheirGoogleID

Now you have their general location, per the reviews they’ve left at various geographical locations.
