Hi all,
Question for the surveillances specialists out there; does anyone use wi-fi to identify locations a subject has been linked to? Could be useful in a loss situation during mobile surveillance.
When someone leaves their wi-fi on, their device (likely to be a phone in this case) will overtly broadcast previous hotspots (aka SSID's or access points) it has connected to. Collecting that information over the air is not illegal. If you can capture that information, you can then search the names of the hotspots using open source websites and identify potential linked locations.
If you haven't visited the site already, I encourage you to try wigle.net and create an account - browse the map and check out the millions if hotspots mapped by the public.
The tactic might already be commonly used in the private world, but thought I'd ask.
That said, if you are running surveillance against a subject make sure you don't leave your own wi-fi on!
