Some of the spy devices U.S. National Security Agency, as described in documents published by Edward Snowden, engineers have been recreated through reverse engineering. Such spyware tools can be connected to the computer and to collect personal information.
Catalog Advanced Network Technology became part of the mass Snowden published secret information. In the catalog you can find descriptions and images of devices with which the NSA agents can retrieve information from your computer and phone. In particular, the mentioned fake base stations and USB-modules with a radio transmitter broadcasting data from the computer to the receiving device. Also in the catalog mentions the mysterious device called retroreflectors with features like eavesdropping, capture keystrokes and screen image.
Computer security experts outside the NSA did not know how to operate the retroreflectors, which means they are unable to offer adequate means of protection against spyware . Researchers led by Michael Ossman , a specialist in software-defined radio systems (ERP), were able to understand the workings of the reflectors.
The reflector can be mounted on the monitor cable (image capture), keyboards (capture and hold). After long-term experiments Osmani managed to create enough small device with an antenna . ERP proved to be convenient for the reception of the reflected signal, because the system can instantly tune to any, even scattered in different ranges of the signal.
Ossmann present its development in August at Defcon hacker conference in Las Vegas.
