LONDON — Documents leaked by former NSA contactor Edward Snowden suggest that spy agencies have a powerful ally in Angry Birds and a host of other apps installed on smartphones across the globe.
The documents, published Monday by the New York Times, Britain's Guardian newspaper and ProPublica, suggest that the mapping, gaming and social networking apps that are a common feature of the world's estimated 1 billion smartphones can feed America's National Security Agency and Britain's GCHQ with huge amounts of personal data, including location information and details such as political affiliation or sexual orientation.
The size and scope of the program aren't publicly known, but the reports suggest that U.S. and British intelligence easily get routine access to data generated by apps such as the Angry Birds game franchise or the Google Maps navigation service.
The NSA did not directly comment on the reports but said in a statement Monday that the communications of those who were not "valid foreign intelligence targets" were not of interest to the spy agency.
GCHQ, the British eavesdropping agency, said it did not comment on intelligence matters.
