XcodeGhost

XcodeGhost is a malware that affected a number of iOS apps in 2015. It was discovered that a number of apps available on the Apple App Store had been infected with the malware, which had been introduced via a compromised version of the Xcode development tool. The malware was able to steal sensitive information from infected devices, including the device's name and type, the app's name and bundle ID, and the device's current location. It also had the ability to open URLs and execute JavaScript, which could have been used to perform other malicious actions such as phishing attacks.

The malware was spread by developers in China who were using a compromised version of the Xcode development tool, which had been distributed through unofficial channels. The malware was able to infect apps that were built with this version of the tool, and was able to evade detection by Apple's security systems. The infected apps were available for download on the Apple App Store for a period of time before being discovered and removed.

The incident served as a reminder that even the most secure platforms and ecosystems can still be vulnerable to malware and other malicious attacks, and that it is important for developers and users to stay vigilant and take steps to protect themselves.

It is also important to note that, Apple has strict rules and security measures to prevent this kind of malware and other malicious software from appearing on its App Store. And they have been successful in preventing such incidents in recent years.
