Decrypt Keychain.Plist10/26/2022 ![]() ![]()
This filesystem is to be used when specifying a backup directory for idevicebackup2. Because it discards most of the backed up data, such a backup will consume less than 10 MB of real disk space. It contains a hard-coded list of files, like a white list, that should have their contents preserved, ist being one of them. #DECRYPT KEYCHAIN.PLIST FREE#This file system exposes a “disk” (or mount point) that reports at least 128 GB of free space, and will preserve file names and other metadata but not the file contents. I’m particularly proud of this name because my project names are usually very unoriginal. ![]() To solve these issues, I created a FUSE-based filesystem called the Fake iOS Backup Filesystem, or fibfs for short. 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. #DECRYPT KEYCHAIN.PLIST PASSWORD#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. ![]() #DECRYPT KEYCHAIN.PLIST PC#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. Support added to hashcat to crack iTunes Backups (iOS 6/7/8/9/10): /forum/thread-6… January 26, 2017 #DECRYPT KEYCHAIN.PLIST FULL#You can work around this error by manually specifying the full path to the default system version of python that ships with your OS X version: $ /usr/bin/python MMeDecrypt.Following the recent announcement of LUKS support in hashcat, I noticed that there have been some commits to support iTunes Backup passwords as well. If you are using a homebrew-installed version of python you may see the following error when running the script: $ python MMeDecrypt.pyįrom Foundation import NSData, NSPropertyListSerialization MIPToken = AQAAAABXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX~ MFAppToken = AQAAAABXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX~ TMMInfiniteToken = AQAAAABXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX~ UthToken = AQAAAABXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX= Token = AQAAAAXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX~ Token extraction without needing KeychainĪuthentication tokens are cached in a database on macOS Įssfully decrypted token Bob Loblaw -> ĭKitToken = AQAAAABYXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX~ Description: Decrypts and extracts iCloud and MMe authorization tokens on Apple macOS / OS X. ![]()
