After the extraction, the password is reset to its original state. We addressed this issue by making iOS Forensic Toolkit set a temporary password (“123”) when performing logical acquisition. As a result, the physical acquisition process can extract but cannot decrypt the keychain, while keychain data backed up without a password remains similarly inaccessible. Secure Enclave introduced in 64-bit devices (iPhone 5s, 6/6s/Plus) effectively locked us out, blocking access to the hardware key regardless of jailbreak status. (We’ll reset it back after extraction.) This allows decrypting keychain data that would otherwise remain inaccessible. For this reason, we’ll automatically set a temporary password (“123”) when acquiring devices without a backup password. If no backup password is set, the keychain will remain securely encrypted with an unbreakable hardware key. See our historical iOS Logical Acquisition: The Last Hope For Passcode-Locked Devices? article, in particular: Long story short: if no other extraction options are available and you can only pull a backup, you need the backup password to be set (and known).īack in 2016, we realized that if a backup password is not set, we just need to set it ourselves, pull the data, and remove the temporary password in the end. Speaking of the keychain, even if the keychain records are always there, we can decrypt them from a backup only if the password is set and known. The problem is that password-protected backups contain more data than ones without password. iOS 13: changing the backup password requires the passcode.iOS 11: made it possible to reset backup passwords in Settings (with some consequences).iOS 10.2: very strong password encryption, extremely slow attacks.iOS 10.1: vulnerability fixed, back to iOS 9 level of protection.iOS 10.0: weak backup password, implementation flaw, very fast attacks.iOS prior to and including iOS 9.x: the password can be effectively attacked.But let’s review the changes made by Apple regarding the backup passwords first: If a backup password is not set, you will need to set it yourself.īoth issues need an explanation.If a backup password has been configured by the device owner and you do not know it, this is a problem.The backup is usually the major source of evidence that includes most of the data from the device.Īs we have already explained, backups are often protected with passwords. Media files (photos, videos, and music, including some metadata)Īnd that’s about it.General device information (model, name, and some other parameters).The logical advanced/extended acquisition/extraction (whatever they call it) may include the following data: #What is teh password to unlock iphone backup on itunes android#In contrast to Android logical extraction, everything is much simpler with iPhones. Instead, they prefer to call it “logical acquisition” or “logical extraction”, sometimes “advanced” or “extended”, and sometimes even “method N”. Most forensic packages avoid using the term “backup”. There is no difference in the data acquired from the device regardless of whether you use Finder or the old iTunes app. In these new versions of macOS, backups are created via Finder. We put the term “iTunes” in quotes simply because there is no iTunes in macOS anymore starting with macOS Catalina (same for macOS Big Sur). We published several dozen articles on iTunes backups, and if you are not familiar with this topic, I recommend you to start with The Most Unusual Things about iPhone Backups I bet you are going to learnt something new. Pulling a backup from the device is nearly always possible regardless the iPhone model and iOS version, but only if the device is unlocked or you can unlock it. Today we have some new tips for you.Īlthough there are several methods for extracting data from an iPhone, iOS backups remain the main source of evidence. We wrote a thousand and one articles about iOS backup passwords, but there is always something fresh that comes out. The backups, as simple as they seem, have many “ifs” and “buts”, especially when it comes to password protection. iTunes-style backups are the core of logical acquisition used by forensic specialists, containing overwhelming amounts of evidence that is is unrivaled on other platforms. The iPhone backup is one of the hottest topics in iOS forensics.
