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, the Guardian, and ProPublica, suggest that the mapping, gaming,
and social networking apps which 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 joint spying program "effectively means that anyone using Google Maps on a smartphone is working in support of a GCHQ system," one 2008 document from the British eavesdropping agency is quoted as saying. Another document - a hand-drawn picture of a smirking fairy conjuring up a tottering pile of papers over a table marked "LEAVE TRAFFIC HERE" - suggests that gathering the data doesn't take much effort.
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.
"Any implication that NSA's foreign intelligence collection is focused on the smartphone or social media communications of everyday Americans is not true," the statement said. "We collect only those communications that we are authorized by law to collect for valid foreign intelligence and counterintelligence purposes - regardless of the technical means used by the targets."
GCHQ said it did not comment on intelligence matters, but insisted that all of its activity was "authorized, necessary and proportionate."
Intelligence agencies' interest in mobile phones and the networks they run on has been documented in several of Snowden's previous disclosures, but the focus on apps shows how everyday, innocuous-looking pieces of software can be turned into instruments of espionage.
Angry Birds, an addictive birds-versus-pigs game which has been downloaded more than 1.7 billion times worldwide, was one of the most eye-catching examples. The Times and ProPublica said a 2012 British intelligence report laid out how to extract Angry Bird users' information from phones running the Android operating system.
Another document, a 14-page-long NSA slideshow published to the Web, listed a host of other mobile apps, including those made by social networking giant Facebook, photo sharing site Flickr, and the film-oriented Flixster.
It wasn't clear precisely what information can be extracted from which apps, but one of the slides gave the example of a user who uploaded a photo using a social media app. Under the words, "Golden Nugget!" it said that the data generated by the app could be examined to determine a phone's settings, where it connected to, which websites it had visited, which documents it had downloaded, and who its users' friends were. One of the documents said that apps could even be mined for information about users' political alignment or sexual orientation.
Google Inc. and Rovio Entertainment Ltd., the maker of Angry Birds, did not immediately return messages seeking comment on the reports
In an online Q&A last week, Snowden said that "not all spying is bad" but he maintained that the NSA’s bulk data collection is unnecessary and doing more harm than good.
“When we’re sophisticated enough to be able to break into any device in the world we want to (up to and including Angela Merkel’s phone, if reports are to be believed), there’s no excuse to wasting our time collecting the call records of grandmothers in Missouri,” Snowden wrote on the website FreeSnowden.is, in response to questions he took via Twitter.
