Check a Backup with mvt-ios
The backup might take some time. It is best to make sure the phone remains unlocked during the backup process. Afterwards, a new folder will be created under the path you specified using the UDID of the iPhone you backed up.
Decrypting a backup
In case you have an encrypted backup, you will need to decrypt it first. This can be done with
mvt-ios as well:
$ mvt-ios decrypt-backup --help Usage: mvt-ios decrypt-backup [OPTIONS] BACKUP_PATH Decrypt an encrypted iTunes backup Options: -d, --destination TEXT Path to the folder where to store the decrypted backup [required] -p, --password TEXT Password to use to decrypt the backup NOTE: This argument is mutually exclusive with arguments: [key_file]. -k, --key-file PATH File containing raw encryption key to use to decrypt the backup NOTE: This argument is mutually exclusive with arguments: [password]. --help Show this message and exit.
You can specify either a password via command-line or pass a key file, and you need to specify a destination path where the decrypted backup will be stored. Following is an example usage of
mvt-ios decrypt-backup -p password -d /path/to/decrypted /path/to/backup
mvt-ios on a Backup
Once you have a decrypted backup available for analysis you can use the
$ mvt-ios check-backup --help Usage: mvt-ios check-backup [OPTIONS] BACKUP_PATH Extract artifacts from an iTunes backup Options: -i, --iocs PATH Path to indicators file -o, --output PATH Specify a path to a folder where you want to store JSON results -f, --fast Avoid running time/resource consuming features -l, --list-modules Print list of available modules and exit -m, --module TEXT Name of a single module you would like to run instead of all --help Show this message and exit.
Following is a basic usage of
mvt-ios check-backup --output /path/to/output/ /path/to/backup/udid/
This command will create a few JSON files containing the results from the extraction. If you do not specify a
mvt-ios will just process the data without storing results on disk.
--iocs argument you can specify a STIX2 file defining a list of malicious indicators to check against the records extracted from the backup by mvt. Any matches will be highlighted in the terminal output as well as saved in the output folder using a "_detected" suffix to the JSON file name.
