It also expresses disappointment that the company released a cracked version of the jailbreak.įirst and foremost, and of utmost concern, is privacy. While the group cleared up much of the situation in its first letter and removed Taig following piracy concerns, the latest letter addresses questions specifically regarding if any money was exchanged with Taig. The biggest questions many are still asking are related to why and how the group made a deal with Taig, an app store of sorts that was installed on jailbroken devices in China, while not including an updated Cydia store in the release. We therefore believe that the only safe way of removal is a full restore, which means the removal and loss of the jailbreak.Ĭydia developer Jay Freeman, aka Saurik, pointed out on Reddit that adding random download URLs to Cydia is as risky as opening attachments received in spam emails.Īfter much controversy surrounding the surprise release of a public iOS 7 jailbreak from well-known jailbreakers the evad3rs, the team has published another open letter to clear up some questions and concerns related to the release. However it is still unknown how the dynamic library ends up on the device in the first place and therefore it is also unknown if it comes with additional malware gifts. Using SSH/Terminal, check the path /Library /MobileSubstrate /DynamicLibraries / for the presence of either Unflod.dylib or framework.dylib.Ĭurrently the jailbreak community believes that deleting the Unflod.dylib/framework.dylib binary and changing the apple-id’s password afterwards is enough to recover from this attack. The blog post says that the malware is easy to check for, but may not be easy to remove. Esser has identified that the code only runs on 32-bit devices, meaning that the iPhone 5s, iPad Air and iPad mini with Retina display are safe, while other devices are vulnerable. From these connections it tries to steal the device’s Apple-ID and corresponding password and sends them in plaintext to servers with IP addresses in control of US hosting companies for apparently Chinese customers.Įarly indications are that the source of the malware is likely to have been from a tweak downloaded from somewhere outside of Cydia. This malware appears to have Chinese origin and comes as a library called Unflod.dylib that hooks into all running processes of jailbroken iDevices and listens to outgoing SSL connections. Security researcher Stefan Esser (via ArsTechnica) has discovered that an issue reported on Reddit as causing crashes on jailbroken iPhones and iPads is actually a piece of malware designed to capture Apple IDs and passwords from infected devices. The company also notes that not jailbreaking iOS devices is the only way to protect against such exploitation. We also suggest all affected users change their Apple account password after removing the malware, and enable two-factor verifications for Apple IDs. ![]() If any dylib file contains any one of these strings, we urge users to delete it and delete the plist file with the same filename, then reboot the device. ![]() Go to /Library/MobileSubstrate/DynamicLibraries/, and grep for these strings to all files under this directory:.Users can use the following method to determine by themselves whether their iOS devices was infected: Further details over at the company’s lengthy blog entry. If you think your iPhone or iPad may be at risk, Palo Alto Networks has provided the following instructions to detect and remove the malware. The tweaks used the stolen credentials to make the purchases. The malware was used in two tweaks that allow those running them to download paid apps and make in-app purchases from Apple’s official App Store without payment. However, it’s extremely unlikely that you’re at risk: the malware can only run on jailbroken devices, and appears to spread through only one set of Cydia repositories, run by Weiphone. The tweaks have been downloaded over 20,000 times, which suggests around 20,000 users are abusing the 225,000 stolen credentials. ![]() These two tweaks will hijack app purchase requests, download stolen accounts or purchase receipts from the C2 server, then emulate the iTunes protocol to log in to Apple’s server and purchase apps or other items requested by users. The malware, dubbed KeyRaider, also has the ability to remotely lock jailbroken iOS devices in order to hold them to ransom. Researchers from Palo Alto Networks have discovered that a piece of iOS malware successfully stole more than 225,000 Apple IDs and passwords from jailbroken phones, using them to make purchases from the official App Store.
