Germany's foreign intelligence service, the BND, and its domestic intelligence agency, the Federal Office for the Protection of the Constitution (BfV), used a spying program of the American National Security Agency (NSA). This is evident in secret documents from the US intelligence service that have been seen by SPIEGEL journalists. The documents show that the Office for the Protection of the Constitution was equipped with a program called XKeyScore intended to "expand their ability to support NSA as we jointly prosecute CT (counterterrorism) targets." The BND is tasked with instructing the domestic intelligence agency on how to use the program, the documents say.
According to an internal NSA presentation from 2008, the program is a productive espionage tool. Starting with the metadata -- or information about which data connections were made and when -- it is able, for instance, to retroactively reveal any terms the target person has typed into a search engine, the documents show. In addition, the system is able to receive a "full take" of all unfiltered data over a period of several days -- including, at least in part, the content of communications.
