Apple's iOS App Store just suffered its first major attack

Apple Inc said that it is cleaning up its iOS App Store to remove malicious iPhone and iPad programs identified in the first large-scale attack on the popular mobile software outlet.

The company disclosed the effort after several cyber security firms reported finding a malicious program dubbed XcodeGhost that was embedded in hundreds of legitimate apps.

It is the first reported case of large numbers of malicious software programs making their way past Apple's stringent app review process. Prior to this attack, a total of just five malicious apps had ever been found in the App Store, according to cyber security firm Palo Alto Networks Inc

The hackers embedded the malicious code in these apps by convincing developers of legitimate software to use a tainted, counterfeit version of Apple's software for creating iOS and Mac apps, which is known as Xcode, Apple said.

"We’ve removed the apps from the App Store that we know have been created with this counterfeit software," Apple spokeswoman Christine Monaghan said in an email. "We are working with the developers to make sure they’re using the proper version of Xcode to rebuild their apps."

She did not say what steps iPhone and iPad users could take to determine whether their devices were infected.

Researchers said infected apps included Tencent Holdings Ltd’s <0700 .hk=""> popular mobile chat app WeChat, car-hailing app Didi Kuaidi and a music app from Internet portal NetEase Inc.

The tainted version of Xcode was downloaded from a server in China that developers may have used because it allowed for faster downloads than using Apple's U.S. servers, Olson said.

Chinese security firm Qihoo360 Technology Co said on its blog that it had uncovered 344 apps tainted with XcodeGhost.

Apple declined to say how many apps it had uncovered.
