![]() However, with the recently published blackbird vulnerability, we are able to get control of the Secure Enclave on A10 and A10X and disable this mitigation. The release notes for the latest version read: If you look at the checkra1n jailbreak, you might be confused even more. For example, the T8010 is the one used in the iPad 6 th and 7 th gen, iPhone 7 and 7 Plus, and iPod Touch 7 th gen. The developers state that it is compatible with the iPhone 4s through iPhone X range of devices, but in fact the compatibility matrix is a bit more complex: The exploit’s compatibility is difficult to grasp. ![]() The checkm8 exploit is the thing you might’ve already heard about. Red: you cannot do anything with locked devices.BFU (Before First Unlock) is possible regardless of iOS version, but the devil is in the detail (see below) Blue: devices vulnerable co checkm8 exploit.Green: you can do almost everything, including passcode cracking, and even perform BFU extractions (may be limited if the password is not known).Noted the different colors? Here is the explanation. We have collected information from public sources and compiled this information for you: How does that affect the compatibility of available acquisition methods? Is that the only factor or there is something else except iOS version? Apple uses ARM processors of its own design the current one for now is A14, which appears in the iPad Air (2020). ![]() The heart of every Apple device is the SoC, or System on a chip. The only reliable method is opening the | and checking the model. Just note that some iPhone and iPod models may share the same external design, and sometimes the back cover is replaced with the one from a different model. Once you are done, search across the above-mentioned pages. Usually it is as simple as that: check the back cover of the device (the iPhone, iPad or iPod Touch) and check the model number in the Axxxx format. The Apple Watch is missing here, though there is an article on them, too the problem is that Apple Watch acquisition is very limited. What do those references mean, and how are the iPhone and iPad models related? Can we count the iPod Touch and Apple TV, too? Let’s have a look. This is especially common when discussing iOS forensics, particularly referring to the checkra1n jailbreak. Security researchers and developers of various iOS jailbreaks and exploits often list a few iPhone models followed by a note that mentions “compatible iPad models”. In particular, some keychain items containing authentication credentials for email accounts and a number of authentication tokens are available before first unlock to allow the iPhone to start up correctly before the user punches in the passcode.When investigating iOS devices, you may have seen references to the SoC generation. The company has discovered certain parts of data being available in iOS devices even before the first unlock. It is the “almost” part of the “everything” that’s being targeted by ElcomSoft iOS Forensic Toolkit. In other words, almost everything inside the iPhone remains encrypted until the user unlocks it with their passcode after the phone starts up. The screen lock passcode is required by Secure Enclave to produce the encryption key, which in turn is used to decrypt the iPhone’s file system. In Apple’s world, the content of the iPhone remains securely encrypted until the moment the user taps in their screen lock passcode. BFU devices are phones that have been powered off or rebooted and have never been subsequently unlocked, not even once, by entering the correct screen lock passcode. ![]() The BFU stands for “Before First Unlock”.

Partial keychain extraction is now possible from disabled and locked iPhones in BFU (Before First Unlock) state even if the screen lock password is not known.īFU keychain extraction is available on select Apple devices and requires installing the checkra1n jailbreak. Version 5.21 adds partial extraction of iOS Keychain from select Apple devices running all versions of iOS from iOS 12 to iOS 13.3. Ltd. updates iOS Forensic Toolkit, the company’s mobile forensic tool for extracting data from a range of Apple devices.
