On Sunday, iTunes accounts were compromised and a rogue developer managed to get 42 of the top 50 sales positions on App Store. In a reply to Engadget, Apple confirms the fraudulent activity on iTunes of Thaut Nguyen, who somehow managed to hijack accounts and download his books.
"The developer Thuat Nguyen and his apps were removed from App Store for violating developer Program License Agreement, including fraudulent purchase patterns.
Developers don't receive any iTunes confidential customer data when an app is downloaded.
