Apple will reveal a list of the 25 most popular apps that have been affected by the XCodeGhost bug, days after it was revealed that its App Store had suffered its first-ever malware attack.

In a post on its official website in China, where hackers have targeted iPhone and iPad users, Apple said: “A list of the top 25 most popular apps impacted will be listed soon so users can easily verify if they have downloaded the latest versions of these apps.

"After the top 25 impacted apps, the number of impacted users drops significantly.”

The company is also set to inform users directly if they have downloaded an app affected by XCodeGhost.

The tech giant says it does not believe any personal information, such as bank details and iCloud passwords, have been compromised.

XCodeGhost affects apps created using code that was not downloaded directly from Apple by developers.

This means that it is open to attack from those looking to hack what has until now been a wholly secure service.

The bug has not affected apps outside of China, but is embarrassing for Apple, which prides itself on the rigorous testing process through which it puts all iOS apps.
