Apple has listed the top 25 apps affected by the XcodeGhost malware.
Earlier in the week it emerged that the iOS App Store had sustained its first major malware attack. The malicious XcodeGhost program managed to work its way into more than 4,000 apps, according to one independent security report.
While Apple hasn't confirmed the precise number of infected apps, it has now supplied a list of the 25 most popular. They are as follows:
58 Classified, Angry Birds 2, Baidu Music, Battle of Freedom, Call Me MT 2, CarrotFantasy, CarrotFantasy 2, China Unicom Customer Service, Dark Dawn, DiDi, Taxi, DuoDuo Ringtone, Encounter, Flush, Flush HD, Foreign Harbor, Gaode Map, Heroes of Order & Chaos, Himalaya FM, I Like Being With You, Let’s Cook, Miraculous Warmth, NetEase Music, One Piece, Railroad 12306, WeChat.
If you're wondering why Apple has only revealed the top 25 apps affected by XcodeGhost, it's because "after the top 25 impacted apps, the number of impacted users drops significantly."
Also, if you're worried over the fact that the popular Angry Birds 2 is listed among these apps, you probably don't need to be. It's only the versions of the game available in the China, Taiwan, Hong Kong, and Macau App Stores that were affected.
Apple advises that any customers using one of these apps "should update the affected app which will fix the issue on the user’s device."
If a previously infected app is available on the App Store, Apple says that it has now been updated and fixed.
The developers of XcodeGhost managed to bypass Apple's stringent security measures by fooling app developers into using a modified version of Apple's own Xcode development tool.
This particularly affected developers in China, where downloading the official Xcode tools direct from Apple can be problematic, so unofficial mirror sites are often used.
