WikiLeaks Dump Reveals a Creepy CIA Location-Tracking Trick
How many people specifically know where you are right now? Some friends and family? Your coworkers, maybe? If you're using a Windows laptop or PC you could add another group to the list: the CIA.
New documents released on Wednesday as part of WikiLeaks' series of CIA hacking revelations detail a method the agency uses to geolocate computers and the people using them. The agency infects target devices with malware that can then check which public Wi-Fi networks a given computer can connect to at a given moment, as well as the signal strengths of those networks. From there, the malware compares the list of available Wi-Fi options to databases of public Wi-Fi networks to figure out roughly where the device is.
The leaked documents detailing the project, which is known as ELSA, date back to 2013, and specifically address laptops and PCs running Windows 7. But experts say that the technique is straightforward enough that the CIA could have a version of it for every Windows release.
