I dont believe that users got scammed due to downloading fake app directly from App Store. All apps passes tons of moderation before getting into App Store. Despite Google Play Store, which is full of fake and scam apps. It is mentioned that he had downloaded an app from App Store. That is a lie, there is no such app there and never was. Just another case of a user that does not care much about his security, as he "downloaded an app to check his balance". This is the same as checking cards balance on http://ismycreditcardstolen.com/ (warning! do not post your private data there)
