Once you launch Elcomsoft iOS Forensic Toolkit, you’ll see a list of available options. If jailbreak cannot be installed, stop right here and consider other acquisition options. Jailbreaking the device may require disabling Find My Phone, which in turn requires you to enter the correct Apple ID password. No: you’ll have to jailbreak the device subject to jailbreak availability. Go to Settings -> Security and disable passcode protection (you’ll have to enter the passcode to do that). Yes: if it’s locked and you don’t know the passcode, stop right here. Is the device locked with an unknown passcode? You will need to unlock the device and disable passcode in Settings (which requires entering the original passcode) before you can perform physical acquisition.įor 64-bit devices, the acquisition process looks like this: There is no way to acquire a 64-bit iOS device if it is locked with a passcode and the passcode is not known, even if the device is already jailbroken. These 64-bit devices are equipped with Secure Enclave, and require a different process for physical acquisition. No guarantee for longer and alphanumerical passcodes. Brute-forcing a 4-digit passcode on jailbroken 32-bit devices is possible within reasonable time with 20 to 25 passwords per second. Mail, keychain, some apps data remains encrypted until you have the correct passcode. Similar to older devices, without a passcode you can decrypt most but not all information extracted from the device. This will extract and decrypt the keychain, then extract user data and decrypt it. Use the following commands in this sequence: Get keys, Decrypt keychain, then Image disk, Decrypt disk. Install it on the iPhone from Cydia repository. Jailbreaking the device may require removing lock screen passcode and disabling Find My Phone, which in turn requires you to enter the correct Apple ID password. If the device is locked and you don’t know the passcode, you will not be able to jailbreak it. For iPhone 4S, 5 and 5C, there acquisition process is different and does not require a DFU mode. These phones can only be acquired if jailbroken. Breaking a 4-digit passcode on these devices is very straightforward and reasonably fast (4-5 passcodes per second on iPhone 4). In particular, without a passcode the following data remains encrypted: mail, keychain, and some protected app data. Note, however, that you will still need to recover the passcode in order to recover all encrypted data on the iPhone 4 (but not on older models). Launch EIFT, connect the phone to the computer, boot into DFU mode, and follow the prompts to recover the passcode, image the device, extract decryption keys and decrypt the keychain. All you need is Elcomsoft iOS Forensic Toolkit. Acquiring iPhone 4 and Olderįor these legacy devices, acquisition is trivial regardless of lock status. Now let’s talk about these cases in more detail. If you know the user’s Apple ID and password, or if you have a binary authentication token acquired from the user’s computer, you may be able to download backups from iCloud (iOS 5.x through 8.x) or iCloud Drive (iOS 9.x). So far we found no solutions that work with iOS 9 and later. If you see a solution advertising compatibility with all versions of iOS, this in fact may not be the case. Depending on iOS version installed on the device, you may be able to use a commercial passcode recovery tool (e.g. If the device is locked with an unknown passcode and if it’s newer than iPhone 4, you may need to unlock it in order to perform acquisition. If you have a 64-bit device, it must be unlocked, and screen lock passcode must be removed in Settings. If the iPhone is already jailbroken, a 32-bit device can be acquired even if locked. iPhone 5S, 6/6S, 6/6S Plus and newer (64-bit devices, Secure Enclave, jailbreak required, passcode must be known and removed in Settings).iPhone 4S, 5 and 5C (32-bit devices, no Secure Enclave, jailbreak required, must be able to unlock the device).iPhone 4 and older (acquisition is trivial).What exactly can be done to the device depends on the following factors:įrom the point of view of mobile forensics, there are three distinct generations: This situation is so common, and the market has so many solutions and “solutions” that we felt a short walkthrough is necessary. So you’ve got an iPhone, and it’s locked, and you don’t know the passcode.
