Apple's App Store security breach could be far bigger than first thought - reported the SkyNews.
It was initially thought that just 39 apps were infected by XcodeGhost, which is able to trick users into sharing their usernames and passwords with hackers.
But cybersecurity firm FireEye now says that more than 4,000 apps were infected as a result of the sophisticated attack.
The apps in question were Trojanised by a fake version of developer tool Xcode, which was apparently widely downloaded in China.
It was hosted on a local server, meaning it downloaded faster than the official version hosted on Apple's US servers.
Apps affected are those which are popular in China, such as Tencent's WeChat app which is used by 600 million people.
Apple has been stripping the App Store of the malicious apps, and has contacted developers asking them to check that they are using genuine software.
It said: "Apple takes security very seriously and iOS is designed to be reliable and secure from the moment you turn on your device.
"To protect our customers, we've removed the apps from the App Store that we know have been created with this counterfeit software and we are working with the developers to make sure they're using the proper version of Xcode to rebuild their apps."
Meanwhile, a security firm is offering a $1m bounty to anyone who can crack Apple's new operating system.
It says the exploit - or jailbreak - of iOS 9 must be must be reliable, silent, and not require any user actions other than visiting a web page or reading a text message.
