Apple has removed all applications belonging to developer Thuat Nguyen from its iTunes App Store.
The company has confirmed that the developer had used fraudulent activities to boost the sale of its applications, Network World reports.
Apple consumers had complained that their iTunes account had been hacked to purchase eBook applications created by the developer, boosting the popularity of 42 of the applications, causing them to be featured in the top 50 best selling applications on the iTunes App Store.
iPhone developer Alexandru Brie explained on his blog that the developer had hacked iTunes App Store accounts to fraudulently use customers' credit cards to purchase the applications.
Brie said: "It seems people's iTunes accounts have been hacked, with mass purchases of one developer's apps being made using their accounts."
He added: "This is a new kind of internet theft (the first of its kind that I hear of), and such a vulnerability is a major threat to all that Apple’s AppStore ecosystem means: a safe, secure place for people to download legitimate and curated apps."
In an e-mailed statement to Engadget, Apple said: “The developer Thuat Nguyen and his apps were removed from the App Store for violating the developer Program License Agreement, including fraudulent purchase patterns.”
