Security firm FireEye said in a blog post that XcodeGhost – a fake version of Xcode that injected malware into genuine apps – remains a threat. FireEye has identified a more advanced version of the compromised app development tool, XcodeGhost S, which has been designed to infect iOS 9 apps and allow compromised apps to escape detection by Apple.
XcodeGhost is planted in different versions of Xcode, including Xcode 7 (released for iOS 9 development). In the latest version, which we call XcodeGhost S, features have been added to infect iOS 9 and bypass static detection.
We have worked with Apple to have all XcodeGhost and XcodeGhost samples we have detected removed from the App Store.
The company said that by monitoring its customers’ networks, it identified 210 enterprises with infected apps running inside their networks – a third of them in the USA – generating 28,000 attempts to connect to the XcodeGhost Command and Control (CnC) servers … expand full story

Patrick Wardle, director of research at security firm Synack, told arsTechnica that once Gatekeeper okays an approved app, it pays no more attention to what that app does. The approved app can then open malicious apps – which Gatekeeper doesn’t check.
Wardle has found a widely available binary that’s already signed by Apple. Once executed, the file runs a separate app located in the same folder as the first one […] His exploit works by renaming Binary A but otherwise making no other changes to it. [He then] swaps out the legitimate Binary B with a malicious one and bundles it in the same disk image under the same file name. Binary B needs no digital certificate to run, so it can install anything the attacker wants …

Apple is to make Xcode available for local download from servers based in China as part of its response to the XcodeGhost malware issue. The announcement was made on the Chinese social media site Sina by Phil Schiller, Apple’s senior VP of worldwide marketing (via CNET). It’s believed that many Chinese developers inadvertently downloaded the fake version because the official download was taking too long.
“In the US it only needs 25 minutes to download,” Schiller told Sina, admitting that in China getting Xcode “may take three times as long.” He told the Chinese publication that, to quell this problem, Apple would be providing an official source for developers in the People’s Republic to download Xcode domestically.

App analytics company SourceDNA – whose clients include Google, Amazon and Dropbox – claims that the compromised versions of many apps remain live in the Chinese App Store. This includes CamCard, which is a very popular app ranked #94.
The apps were infected with malware by a fake version of Xcode dubbed XcodeGhost which legitimate developers were fooled into downloading, believing it to be a copy of the genuine Apple app. A partial list of infected apps has been posted by security company Palo Alto Networks … expand full story
