I'm not sure the backup would be much help even if you could break into it, I believe it's encrypted with the same method used to protect the keychain and is tied to the victim's Apple ID. I attempted to help a coworker restore their device with my Mac and couldn't because my iTunes was using a different Apple ID than the device and the device's backup.
