NYT: Snowden docs reveal NSA has radio pathway into computers, to spy even when device is offline

David E. Sanger and Thom Shanker in the Times today, with a report based in part by documents leaked by Edward Snowden:
The National Security Agency has implanted software in nearly 100,000 computers around the world that allows the United States to conduct surveillance on those machines and can also create a digital highway for launching cyberattacks. While most of the software is inserted by gaining access to computer networks, the N.S.A. has increasingly made use of a secret technology that enables it to enter and alter data in computers even if they are not connected to the Internet."
