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.
