There has been speculation in the media that NSA targets Angry Birds to collect end user data. The speculation is based on information from documents leaked by Edward Snowden.
The alleged surveillance may be conducted through third party advertising networks used by millions of commercial web sites and mobile applications across all industries. If advertising networks are indeed targeted, it would appear that no internet-enabled device that visits ad-enabled web sites or uses ad-enabled applications is immune to such surveillance. Rovio does not allow any third party network to use or hand over personal end-user data from Rovio’s apps.
This was of course the gist of the NYT article, not that Rovio and the Angry Birds applications could directly be used by the NSA, but that any application that collects personal data, like Angry Birds, could be used indirectly by the NSA for spying, likely via the third party advertising networks Rovio points out above. The point is, you really don’t have any idea how much information you’re sharing right now just by using your favorite iPhone apps.
Or Android, etc. ↩
