The CIA is able to locate GPS users without GPS
The Agency developed an internal project known as ELSA, a project aimed at locating the geographical location of users of Windows computers without the need for a GPS system within computers, through Wi-Fi networks.
The agency used to plant files inside the computers of the victims to gather information about Wi-Fi networks near the computer, even without connecting to those networks. Once the list is obtained, the agency searches within a database to try to find out where these networks are located, as well as the power of the signal to determine the location. The central area of ​​the networks is approximately 30 meters and the device can be counted depending on the signal.
This may not be 100% effective, but it allows the agency in one way or another to try geolocation, a method that is also used to locate smartphone users by searching for towers where the phone is connected.
It is not known whether the CIA targeted all Windows computers or a specific set of users. Also, you do not know the files you've planted to search for and remove them if they exist.
