This is the kind of NSA story that really doesn’t bother me. Nonetheless it is epically neat. David E. Sanger and Thom Shanker:
The technology, which the agency has used since at least 2008, relies on a covert channel of radio waves that can be transmitted from tiny circuit boards and USB cards inserted surreptitiously into the computers. In some cases, they are sent to a briefcase-size relay station that intelligence agencies can set up miles away from the target.
