When you are in the process of acquiring an iOS device, your tool may give you a clue as to what you will be dealing with when parsing the data. Here we can see that UFED is prompting us to “Encrypt backup” for Beth’s iPhone. Your tool may only prompt you if iTunes has not already encrypted the backup. If you do not see this prompt in your tool (assuming you are using a tool like UFED), you will see a screen that states that iTunes backup encryption is already set on the device. Get ready to crack that password if this is the case.
