Anybody who thinks disconnecting their computer from the Internet will keep them safe from the prying eyes of the National Security Agency needs to think again, according to the New York Times. The agency has inserted software into around 100,000 computers worldwide that allows it to spy on those machines, even entering and altering data when they are offline, NSA documents and interviews with security experts reveal. Surveillance targets include the Chinese and Russian militaries as well as Mexican drug targets and even European Union trade bodies.
The surveillance program uses secret radio frequency technology that usually requires hardware to be physically inserted into the targeted computer.
