The iOS 12.4 jailbreak is out, and so is Elcomsoft iOS Forensic Toolkit. Using the two together, one can image the file system and decrypt the keychain of iPhone and iPad devices running most versions of iOS (except iOS 12.3 and and the latest 12.4.1, but 12.4 is still signed right now).

There is more to this jailbreak situation than meets the eye. There is not one but two different jailbreaks: unc0ver and Chimera. Both jailbreak tools come in several versions; the differences between their versions are severe. There is also a tool that can access the file system (but not the keychain) on some iOS devices without a jailbreak. Finally, we’ve been able to jailbreak the Apple TV running affected versions of tvOS.

In this article I’ll explain the differences between the two jailbreaks and their versions, provide information about the tool one can use to access the file system without jailbreaking, and provide instructions on how to safely jailbreak in offline mode.

The two recent jailbreaks, unc0ver and Electra, have finally enabled file system extraction for Apple devices running iOS 11.4 and 11.4.1. At this time, all versions of iOS 11 can be jailbroken regardless of hardware. Let’s talk about forensic consequences of today’s release: keychain and file system extraction.
