What it does: The free Facebook app is one of the most popular social networking apps on the App Store.
What are the risks:
• Sends sensitive data in clear text (no encryption).
• Has access to a user's Location and Contacts Book.
• Uses Google Maps and transmits source or destination location values unencrypted over HTTP.
• Includes file paths to source code files in debug information, stored within the app's executable. These file paths include usernames and information related to the app developer.
Note: The app now handles user authentication better when using a Facebook account to log into third-party sites or services. The app used to have authentication tokens that never expire; the authentication tokens now expire in 1 hour.
