Apple's stringent and sometimes even heavy handed review rules for iOS apps have both been hailed and criticized alike, but its core benefit remains the same, very few malicious apps gets past quality control. However, it's not infallible, as five past iOS malware can attest to. Now a sixth joins that list, but with more far-reaching consequences. Dozens, if not hundreds, of App Store apps, specifically in China, might be infected by the XcodeGhost malware, and this time, the apps are otherwise legitimate ones and their developers unwitting accomplices. All thanks to an unofficial Xcode installer going around the Internet.
