The NSA reportedly developed a radio transmitter/receiver that could fit in a USB plug or embedded in a laptop as a tiny circuit board. The technology can then move data over a secret radio channel back and forth with a relay station small enough to fit in an oversize briefcase and located as far as eight miles away. Such technology is far more advanced than the malware hackers use today to infect corporate networks to steal documents that can be sold on the black market or handed to government agencies.”]
