Had to run an additional Docker flag to get it building on the new M1 chip from Apple. Figured it would be helpful to point that out in the Docs for the less initiated users.
Not every system uses 'utf-8' as a default encoding for opening files in Python.
Before you say that there must be a way to set default encoding in one line, no, there is not. At least, I didn't found a way to do this.

Adds download-indicators for mvt-ios and mvt-android
In b2afce5c79, the db filename is
wrapped in double-quotes when passing it to the sqlite3 tool's
`.clone` helper command.
For parsing safety, we avoid performing this cleanup if the filename
itself has a double-quote character in it. Otherwise, a malformed
filename could lead to arbitrary injection into the sqlite3 command.
In be24680046, the sqlite3 wrapping
changes to single-quotes. Either the safety check should be amended
to block pathnames with single-quotes, or the sqlite3 wrapping should
revert to double-quotes.
I opted for the latter here because i think single-quotes are more
likely than double-quotes to show up in pathnames (e.g. a folder named
"Daniel's files"), but either change would be fine, of course.
The two most common reasons that `mvt-ios decrypt-backup` can fail are
wrong passwords and not pointing to an actual backup.
We can distinguish these cases based on the kinds of errors thrown
from iOSbackup (at least for the current versions that i'm testing
with).
When we encounter those particular exceptions, just report a simple
summary and don't overwhelm the user with a backtrace. If we
encounter an unexpected exception, leave the reporting as-is.
Closes: #28, #36
If file_path has any whitespace or shell metacharacters in it, then
the invocation of subprocess.call would be likely to break (or even
accidentally execute code, depending on how perverse the pathnames
are).
It's generally a good plan to avoid shell=True for subprocess.call
where you can lay out the arguments deliberately in python. This one
looks relatively straightforward (but note, i have not tested it,
sorry!)
Note that if a name has a `"` character in it, we still fail, out of
safety reasons.
in particular, we want to avoid command injection into the sqlite
binary with particularly malicious names that look something like the
following:
```
foo.db"; .shell touch should-not-exist; .nullvalue "
```
This offers generic documentation, to show how MVT can be used with
arbitrary STIX-formatted IOCs, while still pointing users at some
known-to-be-useful sample files.
In this stage, the user is likely to want to run `idevicebackup2` in
interactive mode, so clearly specify the `-i` flag in the right place
(just dropping `-i` at the end of the command does not work as
expected -- i think `idevicebackup2 backup encryption on -i` tries to
set the password to `-i`).
More importantly, note that resetting the password by resetting all
the settings runs a risk of removing some of the forensic information.
Etienne identified a file that he thought was wiped as a result of
this in the call this morning, but I don't remember which file it was.
Maybe `id_status_cache.json` ? If you have more concrete info, please
add it here too!
Specifying the password on the command line with `--password XXX`
leaves the password itself visible to any process on the machine which
can scan the process table.
On some systems (including common GNU/Linux distributions) this
visibility is possible by default.
This change should make it possible to offer the password without
putting it into the process table; rather, the user puts the password
in the environment, and specifies the name of the environment
variable, like so:
```
$ export MVT_IOS_BACKUP_PASSWORD=WronglySconeRoundnessUnruffled
$ mvt-ios decrypt-backup -d /path/to/dest /path/to/data/XXXXXXXX-YYYYYYYYYYYYYYY/
$ unset MVT_IOS_BACKUP_PASSWORD
```
or you can do so using a prefixed env var, as described in the updated
check.md documentation.
- The _adb_download function doesn't need a package_name argument. This broke _adb_process_file and unnecessarily clutters function calls. Also, the function may be used to download other files or folders too. Generating a random filename seems like the best solution to me since it is less likely to get a duplicate filename and thus to replace an existing file.
- The path /sdcard/Download doesn't necessarily exist. Using /sdcard seems more reliable.
"which su" will return the path of the su binary, or it will return nothing.
The python boolean of a string with something in it (such as the path of the su binary), will be True.
An empty string (where there is no su binary) will be False.

Mobile Verification Toolkit (MVT) is a collection of utilities to simplify and automate the process of gathering forensic traces helpful to identify a potential compromise of Android and iOS devices.
[Please check out the documentation.](https://mvt.readthedocs.io/en/latest/)
It has been developed and released by the [Amnesty International Security Lab](https://www.amnesty.org/en/tech/) in July 2021 in the context of the [Pegasus project](https://forbiddenstories.org/about-the-pegasus-project/) along with [a technical forensic methodology and forensic evidence](https://www.amnesty.org/en/latest/research/2021/07/forensic-methodology-report-how-to-catch-nso-groups-pegasus/).
*Warning*: MVT is a forensic research tool intended for technologists and investigators. Using it requires understanding the basics of forensic analysis and using command-line tools. This is not intended for end-user self-assessment. If you are concerned with the security of your device please seek expert assistance.
## Installation
First you need to install dependencies, on Linux `sudo apt install python3 python3-pip libusb-1.0-0` or on MacOS `brew install python3 libusb`.
MVT can be installed from sources or from [PyPi](https://pypi.org/project/mvt/) (you will need some dependencies, check the [documentation](https://docs.mvt.re/en/latest/install/)):
Then you can install mvt from pypi with `pip install mvt`, or directly form sources:
```bash
git clone https://github.com/mvt-project/mvt.git
cd mvt
pip3 install .
```
pip3 install mvt
```
Alternatively, you can decide to run MVT and all relevant tools through a [Docker container](https://docs.mvt.re/en/latest/docker/).
**Please note:** MVT is best run on Linux or Mac systems. [It does not currently support running natively on Windows.](https://docs.mvt.re/en/latest/install/#mvt-on-windows)
## Usage
MVT provides two commands `mvt-ios` and `mvt-android` with the following subcommands available:
* `mvt-ios`:
* `check-backup`: Extract artifacts from an iTunes backup
* `check-fs`: Extract artifacts from a full filesystem dump
* `check-iocs`: Compare stored JSON results to provided indicators
* `decrypt-backup`: Decrypt an encrypted iTunes backup
* `mvt-android`:
* `check-backup`: Check an Android Backup
* `download-apks`: Download all or non-safelisted installed APKs
Check out [the documentation to see how to use them](https://mvt.readthedocs.io/en/latest/).

[Read more here.](https://docs.mvt.re/en/latest/license/)
In order to check an Android device over the [Android Debug Bridge (adb)](https://developer.android.com/studio/command-line/adb) you will first need to install [Android SDK Platform Tools](https://developer.android.com/studio/releases/platform-tools). If you have installed [Android Studio](https://developer.android.com/studio/) you should already have access to `adb` and other utilities.
While many Linux distributions already package Android Platform Tools (for example `android-platform-tools-base` on Debian), it is preferable to install the most recent version from the official website. Packaged versions might be outdated and incompatible with most recent Android handsets.
Next you will need to enable debugging on the Android device you are testing. [Please follow the official instructions on how to do so.](https://developer.android.com/studio/command-line/adb)
## Connecting over USB
The easiest way to check the device is over a USB transport. You will need to have USB debugging enabled and the device plugged into your computer. If everything is configured appropriately you should see your device when launching the command `adb devices`.
Now you can try launching MVT with:
```bash
mvt-android check-adb --output /path/to/results
```
If you have previously started an adb daemon MVT will alert you and require you to kill it with `adb kill-server` and relaunch the command.
!!! warning
MVT relies on the Python library [adb-shell](https://pypi.org/project/adb-shell/) to connect to an Android device, which relies on libusb for the USB transport. Because of known driver issues, Windows users [are recommended](https://github.com/JeffLIrion/adb_shell/issues/118) to install appropriate drivers using [Zadig](https://zadig.akeo.ie/). Alternatively, an easier option might be to use the TCP transport and connect over Wi-Fi as describe next.
## Connecting over Wi-FI
When connecting to the device over USB is not possible or not working properly, an alternative option is to connect over the network. In order to do so, first launch an adb daemon at a fixed port number:
```bash
adb tcpip 5555
```
Then you can specify the IP address of the phone with the adb port number to MVT like so:
Where `192.168.1.20` is the correct IP address of your device.
## MVT modules requiring root privileges
Of the currently available `mvt-android check-adb` modules a handful require root privileges to function correctly. This is because certain files, such as browser history and SMS messages databases are not accessible with user privileges through adb. These modules are to be considered OPTIONALLY available in case the device was already jailbroken. **Do NOT jailbreak your own device unless you are sure of what you are doing!** Jailbreaking your phone exposes it to considerable security risks!
Some attacks against Android phones are done by sending malicious links by SMS. The Android backup feature does not allow to gather much information that can be interesting for a forensic analysis, but it can be used to extract SMSs and check them with MVT.
Android supports generating a backup archive of all the installed applications which supports it. However, over the years this functionality has been increasingly abandoned in favor of enabling users to remotely backup their personal data over the cloud. App developers can therefore decide to opt out from allowing the apps' data from being exported locally.
To do so, you need to connect your Android device to your computer. You will then need to [enable USB debugging](https://developer.android.com/studio/debug/dev-options#enable>) on the Android device.
At the time of writing, the Android Debug Bridge (adb) command to generate backups is still available but marked as deprecated.
If this is the first time you connect to this device, you will need to approve the authentication keys through a prompt that will appear on your Android device.
That said, most versions of Android should still allow to locally backup SMS messages, and since messages are still a prime vehicle for phishing and malware attacks, you might still want to take advantage of this functionality while it is supported.
Then you can use adb to extract the backup for SMS only with the following command:
## Generate a backup
Because `mvt-android check-backup` currently only supports checking SMS messages, you can indicate to backup only those:
```bash
adb backup com.android.providers.telephony
```
You will need to approve the backup on the phone and potentially enter a password to encrypt the backup. The backup will then be stored in a file named `backup.ab`.
In case you nonetheless wish to take a full backup, you can do so with
You will need to use [Android Backup Extractor](https://github.com/nelenkov/android-backup-extractor) to convert it to a readable file format. Make sure that java is installed on your system and use the following command:
In order to unpack the backup, use [Android Backup Extractor (ABE)](https://github.com/nelenkov/android-backup-extractor) to convert it to a readable file format. Make sure that java is installed on your system and use the following command:

```
Through the `--iocs` argument you can specify a [STIX2](https://oasis-open.github.io/cti-documentation/stix/intro) 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.

In order to use `mvt-android` you need to connect your Android device to your computer. You will then need to [enable USB debugging](https://developer.android.com/studio/debug/dev-options#enable>) on the Android device.
MVT allows to attempt to download all available installed packages (APKs) in order to further inspect them and potentially identify any which might be malicious in nature.
If this is the first time you connect to this device, you will need to approve the authentication keys through a prompt that will appear on your Android device.
Now you can launch `mvt-android` and specify the `download-apks` command and the path to the folder where you want to store the extracted data:
Optionally, you can decide to enable lookups of the SHA256 hash of all the extracted APKs on [VirusTotal](https://www.virustotal.com) and/or [Koodous](https://www.koodous.com). While these lookups do not provide any conclusive assessment on all of the extracted APKs, they might highlight any known malicious ones:
It might take several minutes to complete.

MVT will likely warn you it was unable to download certain installed packages. There is no reason to be alarmed: this is typically expected behavior when MVT attempts to download a system package it has no privileges to access.

For different technical reasons, it is more complex to do a forensic analysis of an Android phone.
Unfortunately Android devices provide much less observability than their iOS cousins. Android stores very little diagnostic information useful to triage potential compromises, and because of this `mvt-android` capabilities are limited as well.
Currently MVT allows to perform two different checks on an Android phone:
However, not all is lost.
* Download APKs installed in order to analyze them
* Extract Android backup in order to look for suspicious SMS
## Check installed Apps
Because malware attacks over Android typically take the form of malicious or backdoored apps, the very first thing you might want to do is to extract and verify all installed Android packages and triage quickly if there are any which stand out as malicious or which might be atypical.
While it is out of the scope of this documentation to dwell into details on how to analyze Android apps, MVT does allow to easily and automatically extract information about installed apps, download copies of them, and quickly lookup services such as [VirusTotal](https://www.virustotal.com) or [Koodous](https://koodous.com) which might quickly indicate known bad apps.
## Check the device over Android Debug Bridge
Some additional diagnostic information can be extracted from the phone using the [Android Debug Bridge (adb)](https://developer.android.com/studio/command-line/adb). `mvt-android` allows to automatically extract information including [dumpsys](https://developer.android.com/studio/command-line/dumpsys) results, details on installed packages (without download), running processes, presence of root binaries and packages, and more.
## Check an Android Backup (SMS messages)
Although Android backups are becoming deprecated, it is still possible to generate one. Unfortunately, because apps these days typically favor backup over the cloud, the amount of data available is limited. Currently, `mvt-android check-backup` only supports checking SMS messages containing links.
Using Docker simplifies having all the required dependencies and tools (including most recent versions of [libimobiledevice](https://libimobiledevice.org)) readily installed.
Install Docker following the [official documentation](https://docs.docker.com/get-docker/).
Once installed, you can clone MVT's repository and build its Docker image:
```bash
git clone https://github.com/mvt-project/mvt.git
cd mvt
docker build -t mvt .
```
Optionally, you may need to specify your platform to Docker in order to build successfully (Apple M1)
```bash
docker build --platform amd64 -t mvt .
```
Test if the image was created successfully:
```bash
docker run -it mvt
```
If a prompt is spawned successfully, you can close it with `exit`.
If you wish to use MVT to test an Android device you will need to enable the container's access to the host's USB devices. You can do so by enabling the `--privileged` flag and mounting the USB bus device as a volume:
```bash
docker run -it --privileged -v /dev/bus/usb:/dev/bus/usb mvt
```
**Please note:** the `--privileged` parameter is generally regarded as a security risk. If you want to learn more about this check out [this explainer on container escapes](https://blog.trailofbits.com/2019/07/19/understanding-docker-container-escapes/) as it gives access to the whole system.
Recent versions of Docker provide a `--device` parameter allowing to specify a precise USB device without enabling `--privileged`:
Before proceeding, please note that mvt requires Python 3.6+ to run. While it should be available on most operating systems, please make sure of that before proceeding.

## Dependencies on Linux
First install some basic dependencies that will be necessary to build all required tools:
*libusb-1.0-0* is not required if you intend to only use `mvt-ios` and not `mvt-android`.
## Dependencies on Mac
When working with Android devices you should additionally install [Android SDK Platform Tools](https://developer.android.com/studio/releases/platform-tools). If you prefer to install a package made available by your distribution of choice, please make sure the version is recent to ensure compatibility with modern Android devices.
Running MVT on Mac requires Xcode and [homebrew](https://brew.sh) to be installed.
## Dependencies on macOS
Running MVT on macOS requires Xcode and [homebrew](https://brew.sh) to be installed.
In order to install dependencies use:
```bash
brew install python3 libusb
brew install python3 libusb sqlite3
```
*libusb* is not required if you intend to only use `mvt-ios` and not `mvt-android`.
When working with Android devices you should additionally install [Android SDK Platform Tools](https://developer.android.com/studio/releases/platform-tools):
```bash
brew install --cask android-platform-tools
```
Or by downloading the [official binary releases](https://developer.android.com/studio/releases/platform-tools).
## MVT on Windows
MVT does not currently officially support running natively on Windows. While most functionality should work out of the box, there are known issues especially with `mvt-android`.
It is recommended to try installing and running MVT from [Windows Subsystem Linux (WSL)](https://docs.microsoft.com/en-us/windows/wsl/about) and follow Linux installation instructions for your distribution of choice.

## Consensual Forensics
While MVT is capable of extracting and processing various types of very personal records typically found on a mobile phone (such as calls history, SMS and WhatsApp messages, etc.), this is intended to help identify potential attack vectors such as malicious SMS messages leading to exploitation.
MVT's purpose is not to facilitate adversial forensics of non-consenting individuals' devices. The use of MVT and derivative products to extract and/or analyse data originating from devices used by individuals not consenting to the procedure is explicitly prohibited in the [license](license.md).
MVT's purpose is not to facilitate adversarial forensics of non-consenting individuals' devices. The use of MVT and derivative products to extract and/or analyse data originating from devices used by individuals not consenting to the procedure is explicitly prohibited in the [license](license.md).
MVT uses [Structured Threat Information Expression (STIX)](https://oasis-open.github.io/cti-documentation/stix/intro.html) files to identify potential traces of compromise.
These indicators of compromise are contained in a file with a particular structure of [JSON](https://en.wikipedia.org/wiki/JSON) with the `.stix2` or `.json` extensions.
You can indicate a path to a STIX2 indicators file when checking iPhone backups or filesystem dumps. For example:
- [Predator from Cytrox](https://citizenlab.ca/2021/12/pegasus-vs-predator-dissidents-doubly-infected-iphone-reveals-cytrox-mercenary-spyware/) ([STIX2](https://raw.githubusercontent.com/AmnestyTech/investigations/master/2021-12-16_cytrox/cytrox.stix2))
- [This repository](https://github.com/Te-k/stalkerware-indicators) contains IOCs for Android stalkerware including [a STIX MVT-compatible file](https://raw.githubusercontent.com/Te-k/stalkerware-indicators/master/stalkerware.stix2).
You can automaticallly download the latest public indicator files with the command `mvt-ios download-iocs` or `mvt-android download-iocs`. These commands download the list of indicators listed [here](https://github.com/mvt-project/mvt/blob/main/public_indicators.json) and store them in the [appdir](https://pypi.org/project/appdirs/) folder. They are then loaded automatically by mvt.
Please [open an issue](https://github.com/mvt-project/mvt/issues/) to suggest new sources of STIX-formatted IOCs.
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.
## Extracting and saving the decryption key (optional)
If you do not wish to enter a password every time when decrypting a backup, MVT can accept a key file instead. This key can be used with the `decrypt-backup` command.
To generate a key file, you will need your device backup and the backup password:
$ mvt-ios extract-key --help
Usage: mvt-ios extract-key [OPTIONS] BACKUP_PATH

You can specify the password on the command line, or omit the `-p` option to have MVT prompt for a password. The `-k` option specifies where to save the file containing the decryption key. If `-k` is omitted, MVT will display the decryption key without saving.

* Start the backup and wait for it to finish (this may take up to 30 minutes).
* Once the backup is done, find its location and copy it to a place where it can be analyzed by `mvt`. On Windows, the backup can be stored either in `%USERPROFILE%\Apple\MobileSync\` or `%USERPROFILE%\AppData\Roaming\Apple Computer\MobileSync\`.

If you have correctly [installed libimobiledevice](../install.md) you can easily generate an iTunes backup using the `idevicebackup2` tool included in the suite. First, you might want to ensure that backup encryption is enabled (**note: encrypted backup contain more data than unencrypted backups**):
```bash
idevicebackup2 backup encryption on
idevicebackup2 -i backup encryption on
```
Note that if a backup password was previously set on this device, you might need to use the same or change it. You can try changing password using `idevicebackup2 backup changepw` or resetting the password by resetting only the settings through the iPhone's Settings app.
Note that if a backup password was previously set on this device, you might need to use the same or change it. You can try changing password using `idevicebackup2 -i backup changepw`, or by turning off encryption (`idevicebackup2 -i backup encryption off`) and turning it back on again.
If you are not able to recover or change the password, you should try to disable encryption and obtain an unencrypted backup.
If all else fails, as a *last resort* you can try resetting the password by [resetting all the settings through the iPhone's Settings app](https://support.apple.com/en-us/HT205220), via `Settings » General » Reset » Reset All Settings`. Note that resetting the settings through the iPhone's Settings app will wipe some of the files that contain useful forensic traces, so try the options explained above first.
Once ready, you can proceed performing the backup:
While iTunes backup provide a lot of very useful databases and diagnistic data, in some cases you might want to jailbreak the device and perform a full filesystem dump. In that case, you should take a look at [checkra1n](https://checkra.in/), which provides an easy way to obtain root on most recent iPhone models.

!!! warning
Before you checkra1n any device, make sure you take a full backup, and that you are prepared to do a full factory reset before restoring it. Even after using checkra1n's "Restore System", some traces of the jailbreak are still left on the device and [apps with anti-jailbreaks will be able to detect them](https://github.com/checkra1n/BugTracker/issues/279) and stop functioning.

You will need to decide whether to attempt to jailbreak the device and obtain a full filesystem dump, or not.
While access the full filesystem allows to extact data that would otherwise be unavailable, it might not always be possible to jailbreak a certain iPhone model or version of iOS. In addition, depending on the type of jailbreak available, doing so might compromise some important records, pollute others, or potentially cause unintended malfunctioning of the device later in case it is used again.

If you are not expected to return the phone, you might want to consider to attempt a jailbreak after having exhausted all other options, including a backup.
#### iTunes Backup
An alternative option is to generate an iTunes backup (in most recent version of macOS, they are no longer launched from iTunes, but directly from Finder). While backups only provide a subset of the files stored on the device, in many cases it might be sufficient to at least detect some suspicious artifacts. Backups encrypted with a password will have some additional interesting records not available in unencrypted ones, such as Safari history, Safari state, etc.
