VERY IMPORTANT

YiSpecter is different from previously seen iOS malware in that it attacks both jailbroken and non-jailbroken iOS devices through unique and harmful malicious behaviors. Specifically, it’s the first malware we’ve seen in the wild that abuses private APIs in the iOS system to implement malicious functionalities. So far, the malware primarily affects iOS users in mainland China and Taiwan. It spreads via unusual means, including the hijacking of traffic from nationwide ISPs, an SNS worm on Windows, and an offline app installation and community promotion. Many victims have discussed YiSpecter infections of their jailbroken and non-jailbroken iPhones in online forums and have reported the activity to Apple. The malware has been in the wild for over 10 months, but out of 57 security vendors in VirusTotal, only one is detecting the malware at the time of this writing.
