Leaked documents by a whistleblower have provided details that the US National Security Agency has targeted popular smartphone-based social games such as "Candy Crush" and "Angry Birds" to obtain personal information. The data gained from the apps include phone numbers, e-mails and codes that identify the user's device. The Facebook and Google apps that were most heavily targeted included Google Plus, Pinterest, "Candy Crush," and Angry Birds. The agency obtained the data by targeting the advertising services that display ads on the apps and games.
