If anyone still has doubts that the US Central Intelligence Agency (CIA) can track nearly anyone, anytime, anywhere, a new Vault 7 disclosure from WikiLeaks may dispel them.
The CIA likely used malware codenamed ELSA to pinpoint and, presumably, track target Windows users over long periods, by hacking into WiFi radios on laptops – even when not connected to the Internet.
ELSA works by triangulating the location of the target laptop as its WiFi radios actively listen for public access points whose ESS identifier, MAC address and signal strength are recorded at regular intervals. The malware stores the information in an encrypted file on the target computer itself.
