Apple has issued a response to reports of iTunes users seeing their accounts hacked and used to purchase certain apps in order to build App Store rankings. “The developer Thuat Nguyen and his apps were removed from the App Store for violating the developer Program License Agreement, including fraudulent purchase patterns,” Apple told Engadget. “Developers do not receive any iTunes confidential customer data when an app is downloaded. If your credit card or iTunes password is stolen and used on iTunes we recommend that you contact your financial institution and inquire about canceling the card and issuing a chargeback for any unauthorized transactions. We also recommend that you change your iTunes account password immediately.
