XcodeGhost (and variant XcodeGhost S) are a modified versions of Apple's Xcode development environment that are considered malware. The software first gained widespread attention in September 2015, when a number of apps originating from China harbored the malicious code. It was thought to be the "first large-scale attack on Apple's App Store," according to the BBC. The problems were first identified by researchers at Alibaba, a leading e-commerce firm in China. Over 4000 apps are infected, according to FireEye, far more than the 25 initially acknowledged by Apple,〔https://www.fireeye.com/blog/executive-perspective/2015/09/protecting_our_custo.html〕 including apps from authors outside China. Security firm Palo Alto Networks surmised that because network speeds were slower in China, developers in the country looked for local copies for Apple Xcode development environment, and encountered altered versions that had been posted on domestic web sites. This opened the door for the malware to be inserted into high profile apps used on iOS devices. Even two months after the initial reports, security firm FireEye reported that hundreds of enterprises were still using infected apps and that XcodeGhost remained "a persistent security risk". The firm also identified a new variant of the malware and dubbed it XcodeGhost S, and among the apps that were infected were the popular messaging app WeChat and a Netease app Music 163. == Discovery == On September 16, 2015, a Chinese iOS developer mentioned on the social network Sina Weibo that a malware in Xcode injects third party code into apps compiled with it. Alibaba researchers then published detailed informations on the malware and called it XcodeGhost. On September 17, 2015, Palo Alto Networks published several reports on the malware. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「XcodeGhost」の詳細全文を読む スポンサード リンク
