Court documents revealed that the infamous XcodeGhost malware, which has been active since 2015, infected 128 million iOS users. Apple managers were aware of a mass infection that impacted 128 million iPhone users but avoided notifying them. Apple identified more than 2,500 malicious apps that had been totally downloaded 203 million times from the official store impacting roughly 128 million customers. Apple only published a post that provided general information about the malicious campaign and listed only the top 25 most downloaded apps. At the time of the discovery of Xcode Ghost in the App store, the company removed the malicious ass from the App Store.”]
