Recently uncovered PowerPoint slides used by the National Security Agency and its British equivalent indicate that the spy agencies have been intercepting personal data sent by leaky smartphone apps. The New York Times, the Guardian and ProPublica all reported that documents provided by former NSA contractor Edward Snowden showed that the agency and Britains GCHQ collected data transmitted in the clear by Angry Birds, Facebook, Flickr, Flixster, Google Maps, LinkedIn, Photobucket and Twitter. In addition to the vast amount of personal data being transmitted unencrypted across open cellular networks by the apps themselves, the agencies were reportedly able to get even more intrusive information — including a persons religion, sexual orientation and marital status — from third-party advertising networks that placed ads in smartphone apps.
