![]() ![]() With this bit of code (and a jailbroken iPhone) the script will now download the sms.db file, insert new SMSes from Samsung New PC Studio, and upload the file back into the iPhone. If only the bookmark feature actually worked, I wouldn’t have to navigate to the directory every single time. I only implemented the minimal set of functions required to download and upload files to the iPhone, as I wrote this primarily for my iPhone SMS import script.Īs I use the iPhone SMS import script on a regular basis (the Samsung Jet frequently runs out of SMS memory), I got tired of opening iPhone Explorer, copying the file out, running the script, and then copying the file back. I did manage to find a C# equivalent called Manzana though, which is quite widely used.Īnyhow, I bit the bullet and read through the ctypes documentation and wrote AMDevice.py which exposes some simple classes to handle connecting to an iPhone. Oddly enough I can’t seem to find a Python wrapper for iTunesMobileDevice.dll. Of course when I say “we”, I really mean “I”. Sometimes when we setup a VM with libimobiledevice, we might also not have allocated such a large virtual disk. But because the backup process is controlled by the device and not the PC, we can’t simply ask it to send over that single file. ![]() We just need the ist, which is typically less than 50 KB. so that it can determine what has been backed up previously and what to send/update for incremental backups.įor password cracking, we don’t need the entire 64 GB (or God forbid, 128 GB) of data on the iOS device. This process treats the host PC like a dumb disk store, by sending it commands like DLMessageCreateDirectory, DLMessageUploadFiles, DLMessageRemoveFiles, DLMessageGetFreeDiskSpace, etc. The iOS backup process is driven by the device itself, through the BackupAgent process. IOS device backups usually take a while, depending on how much storage has been used on your device. If you cannot get it to work, you can try the Perl script from philsmd instead. You will need the Python bindings from libplist for the script to work. I have written a simplified script which dumps the BackupKeyBag. This keybag is a binary blob, the format of which has already been documented by researchers from Sogeti ESEC Lab. The keys used to encrypt the backup are stored in the BackupKeyBag, which can be found in the ist file. ![]() If the backup is not encrypted then all the files are in clear and there is nothing to bruteforce. This is only useful if the backup was encrypted by setting a backup password on the iOS device.
