This commit makes a structural change to MVT by changing binary
detected/not detected logic into a structured multi-level system
of alerts. This gives far more power to extend MVT and manage
alerts.
This commit also begins the process of adding proper typing for
key objects used in MVT including Indicators, IndicatorMatches,
and ModuleResults. This will also be keep to programmatically using
the output of MVT.
Adding support to automatically run ADB backup and bugreport modules
automatically when running the check-androidqf command. This is a first
step to deduplicate the code for Android modules.
* Use local timestamp for Files module timeline.
Most other Android timestamps appear to be local time. The
results timeline is more useful if all the timestamps
are consistent. I would prefer to use UTC, but that would
mean converting all the other timestamps to UTC as well. We probably
do not have sufficient information to do that accurately,
especially if the device is moving between timezones..
* Add file timestamp modules to add logs into timeline
* Handle case were we cannot load device timezone
* Fix crash if prop file does not exist
* Move _get_file_modification_time to BugReportModule
* Add backport for timezone and fix Tombstone module to use local time.
* Fix import for backported Zoneinfo
* Fix ruff error
* Add initial parser for ADB dumpsys
* Add ADBState tests and support for AndroidQF and
check-adb
* Handle case where ADB is not available in device dumpsys
* Add prelimary ipv4-addr ioc matching support under collection domains
* Add IP addresses as a valid IOC type
This currently just supports IPv4 addresses which
are treated as domains internally in MVT.

Without this change the package doesn't get properly reset when a new
user starts.
See for example in this excerpt:

Here the package "com.android.bluetooth" is not reset when in line 18,
so when "LEGACY_STORAGE:" in line 22 is encountered, it's added as
another permission to "com.android.bluetooth" with "access" set to
"ode=igno".
This PR fixes that by resetting the package whenever a new Uid is
encountered.

Some MVT modules such as the WhatsApp module can be very slow as it was taking a naive approach to look for IOCs. The code was checking URLs (potentially more than 100k) against
1000's of IOC domains resulting in a quadratic run-time with hundreds of millions of comparisons as the number of IOCs increases.
This commit add an Aho-Corasick library which allows the efficient search in a string (the URL in this case) for all matches in set of keys (the IOCs). This data structure is perfect for this use case.
A quick measurement shows a 80% performance improvement for a WhatsApp database with 100k entries. The slow path is now the time spent fetching and expanding short URLs found in the database. This
can also be sped up significantly by fetching each URL asynchronously. This would require reworking modules to split the URL expansion from the IOC check so I will implement in a separate PR.
* Added Documentation for Encrypted Iphone Backup with Finder on MacOS
* Added details on where to check the backups after completion and added screenshots for the process
* Added location of backups
Adds the pip comman for updating mvt. I think this would be helpfull for novice users as it already has been asked here: https://github.com/mvt-project/mvt/discussions/261
Also I sometimes forget the command too ;)

# Contributing to Mobile Verification Toolkit (MVT)
We greatly appreciate contributions to MVT!
Your involvement, whether through identifying issues, improving functionality, or enhancing documentation, is very much appreciated. To ensure smooth collaboration and a welcoming environment, we've outlined some key guidelines for contributing below.
## Getting started
Contributing to an open-source project like MVT might seem overwhelming at first, but we're here to support you!
Whether you're a technologist, a frontline human rights defender, a field researcher, or someone new to consensual spyware forensics, there are many ways to make meaningful contributions.
Here's how you can get started:
1. **Explore the codebase:**
- Browse the repository to get familar with MVT. Many MVT modules are simple in functionality and easy to understand.
- Look for `TODO:` or `FIXME:` comments in the code for areas that need attention.
2. **Check Github issues:**
- Look for issues tagged with ["help wanted"](https://github.com/mvt-project/mvt/issues?q=is%3Aissue+is%3Aopen+label%3A%22help+wanted%22) or ["good first issue"](https://github.com/mvt-project/mvt/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22) to find tasks that are beginner-friendly or where input from the community would be helpful.
3. **Ask for guidance:**
- If you're unsure where to start, feel free to open a [discussion](https://github.com/mvt-project/mvt/discussions) or comment on an issue.
## How to contribute:
1. **Report issues:**
- Found a bug? Please check existing issues to see if it's already reported. If not, open a new issue. Mobile operating systems and databases are constantly evolving, an new errors may appear spontaniously in new app versions.
**Please provide as much information as possible about the prodblem including: any error messages, steps to reproduce the problem, and any logs or screenshots that can help.**
2. **Suggest features:**
- If you have an idea for new functionality, create a feature request issue and describe your proposal.
3. **Submit code:**
- Fork the repository and create a new branch for your changes.
- Ensure your changes align with the code style guidelines (see below).
- Open a pull request (PR) with a clear description of your changes and link it to any relevant issues.
4. **Documentation contributions:**
- Improving documentation is just as valuable as contributing code! If you notice gaps or inaccuracies in the documentation, feel free to submit changes or suggest updates.
## Code style
Please follow these code style guidelines for consistency and readability:
- **Indentation**: use 4 spaces per tab.
- **Quotes**: Use double quotes (`"`) by default. Use single quotes (`'`) for nested strings instead of escaping (`\"`), or when using f-formatting.
- **Maximum line length**:
- Aim for lines no longer than 80 characters.
- Exceptions are allowed for long log lines or strings, which may extend up to 100 characters.
- Wrap lines that exceed 100 characters.
Follow [PEP 8 guidelines](https://peps.python.org/pep-0008/) for indentation and overall Python code style. All MVT code is automatically linted with [Ruff](https://github.com/astral-sh/ruff) before merging.
Please check your code before opening a pull request by running `make ruff`
## Community and support
We aim to create a supportive and collaborative environment for all contributors. If you run into any challenges, feel free to reach out through the discussions or issues section of the repository.
Your contributions, big or small, help improve MVT and are always appreciated.

### Indicators of Compromise
MVT supports using public [indicators of compromise (IOCs)](https://github.com/mvt-project/mvt-indicators) to scan mobile devices for potential traces of targeting or infection by known spyware campaigns. This includes IOCs published by [Amnesty International](https://github.com/AmnestyTech/investigations/) and other research groups.
> **Warning**
> Public indicators of compromise are insufficient to determine that a device is "clean", and not targeted with a particular spyware tool. Reliance on public indicators alone can miss recent forensic traces and give a false sense of security.
>
> Reliable and comprehensive digital forensic support and triage requires access to non-public indicators, research and threat intelligence.
>
>Such support is available to civil society through [Amnesty International's Security Lab](https://securitylab.amnesty.org/get-help/?c=mvt_docs) or through our forensic partnership with [Access Now’s Digital Security Helpline](https://www.accessnow.org/help/).
More information about using indicators of compromise with MVT is available in the [documentation](https://docs.mvt.re/en/latest/iocs/).
## Installation
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/)):

Thank you for your interest in reporting security issues and vulnerabilities! Security research is of utmost importance and we take all reports seriously. If you discover an issue please report it to us right away!
Please DO NOT file a public issue, instead send your report privately to *nex [at] nex [dot] sx*. You can also write PGP-encrypted emails to [this key](https://keybase.io/nex/pgp_keys.asc?fingerprint=05216f3b86848a303c2fe37dd166f1667359d880).
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.
# Deprecation of ADB command in MVT
!!! 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
The `mvt-android check-adb` command has been deprecated and removed from MVT.
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:
The ability to analyze Android devices over ADB (`mvt-android check-adb`) has been removed from MVT due to several technical and forensic limitations.
```bash
adb tcpip 5555
```
## Reasons for Deprecation
Then you can specify the IP address of the phone with the adb port number to MVT like so:
1. **Inconsistent Data Collection Across Devices**
Android devices vary significantly in their system architecture, security policies, and available diagnostic logs. This inconsistency makes it difficult to ensure that MVT can reliably collect necessary forensic data across all devices.
The `check-adb` command did not retrieve a full forensic snapshot of all available data on the device. For example, critical logs such as the **full bugreport** were not systematically collected, leading to potential gaps in forensic analysis. This can be a serious problem in scenarios where the analyst only had one time access to the Android device.
Where `192.168.1.20` is the correct IP address of your device.
4. **Code Duplication and Difficulty Ensuring Consistent Behavior Across Sources**
Similar forensic data such as "dumpsys" logs were being loaded and parsed by MVT's ADB, AndroidQF and Bugreport commands. Multiple modules were needed to handle each source format which created duplication leading to inconsistent
behavior and difficulties in maintaining the code base.
## MVT modules requiring root privileges
5. **Alignment with iOS Workflow**
MVT’s forensic workflow for iOS relies on pre-extracted artifacts, such as iTunes backups or filesystem dumps, rather than preforming commands or interactions directly on a live device. Removing the ADB functionality ensures a more consistent methodology across both Android and iOS mobile forensic.
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!
## Alternative: Using AndroidQF for Forensic Data Collection
To replace the deprecated ADB-based approach, forensic analysts should use [AndroidQF](https://github.com/mvt-project/androidqf) for comprehensive data collection, followed by MVT for forensic analysis. The workflow is outlined in the MVT [Android methodology](./methodology.md)
In case you nonetheless wish to take a full backup, you can do so with
```bash
adb backup -all
adb backup -nocompress -all
```
## Unpack the backup
Some recent phones will enforce the utilisation of a password to encrypt the backup archive. In that case, the password will obviously be needed to extract and analyse the data later on.
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:
## Unpack and check the backup
MVT includes a partial implementation of the Android Backup parsing, because of the implementation difference in the compression algorithm between Java and Python. The `-nocompress` option passed to adb in the section above allows to avoid this issue. You can analyse and extract SMSs from the backup directly with MVT:
INFO [mvt.android.modules.backup.sms] Extracted a total of 64 SMS messages
```
If the backup is encrypted, MVT will prompt you to enter the password. A backup password can also be provided with the `--backup-password` command line option or through the `MVT_ANDROID_BACKUP_PASSWORD` environment variable. The same options can also be used to when analysing an encrypted backup collected through AndroidQF in the `mvt-android check-androidqf` 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.
## Alternative ways to unpack and check the backup
If you encounter an issue during the analysis of the backup, you can alternatively 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:
16:18:38 INFO [mvt.android.cli] Checking ADB backup located at: .
INFO [mvt.android.modules.backup.sms] Running module SMS...
INFO [mvt.android.modules.backup.sms] Processing SMS backup file at /path/to/backup/apps/com.android.providers.telephony/d_f/000000_sms_backup
16:18:39 INFO [mvt.android.modules.backup.sms] Extracted a total of
64 SMS messages containing links
```
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.
You can then extract SMSs with MVT by passing the folder path as parameter instead of the `.ab` file: `mvt-android check-backup --output /path/to/results/ /path/to/backup/` (the path to backup given should be the folder containing the `apps` folder).
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.

You can do so by launching the following command:

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.
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://koodous.com). While these lookups do not provide any conclusive assessment on all of the extracted APKs, they might highlight any known malicious ones:

Please note that in order to use VirusTotal lookups you are required to provide your own API key through the `MVT_VT_API_KEY` environment variable. You should also note that VirusTotal enforces strict API usage. Be mindful that MVT might consume your hourly search quota.
In case you have a previous extraction of APKs you want to later check against VirusTotal, you can do so with the following arguments:
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.
Unfortunately Android devices provide fewer complete forensically useful datasources than their iOS cousins. Unlike iOS, the Android backup feature only provides a limited about of relevant data.
Android diagnostic logs such as *bugreport files* can be inconsistent in format and structure across different Android versions and device vendors. The limited diagnostic information available makes it difficult to triage potential compromises, and because of this `mvt-android` capabilities are limited as well.
However, not all is lost.
## Check installed Apps
## Check Android devices with AndroidQF and MVT
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.
The [AndroidQF](https://github.com/mvt-project/androidqf) tool can be used to collect a wide range of forensic artifacts from an Android device including an Android backup, a bugreport file, and a range of system logs. MVT natively supports analyzing the generated AndroidQF output for signs of device compromise.
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.
### Why Use AndroidQF?
- **Complete and raw data extraction**
AndroidQF collects full forensic artifacts using an on-device forensic collection agent, ensuring that no crucial data is overlooked. The data collection does not depended on the shell environment or utilities available on the device.
- **Consistent and standardized output**
By collecting a predefined and complete set of forensic files, AndroidQF ensures consistency in data acquisition across different Android devices.
- **Future-proof analysis**
Since the full forensic artifacts are preserved, analysts can extract new evidence or apply updated analysis techniques without requiring access to the original device.
- **Cross-platform tool without dependencies**
AndroidQF is a standalone Go binary which can be used to remotely collect data from an Android device without the device owner needing to install MVT or a Python environment.
### Workflow for Android Forensic Analysis with AndroidQF
With AndroidQF the analysis process is split into a separate data collection and data analysis stages.
1. **Extract Data Using AndroidQF**
Deploy the AndroidQF forensic collector to acquire all relevant forensic artifacts from the Android device.
2. **Analyze Extracted Data with MVT**
Use the `mvt-android check-androidqf` command to perform forensic analysis on the extracted artifacts.
By separating artifact collection from forensic analysis, this approach ensures a more reliable and scalable methodology for Android forensic investigations.
For more information, refer to the [AndroidQF project documentation](https://github.com/mvt-project/androidqf).
## 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.
The ability to analyze Android devices over ADB (`mvt-android check-adb`) has been removed from MVT.

## 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.
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.
The `mvt-android check-androidqf` command will automatically check an Android backup and SMS messages if an SMS backup is included in the AndroidQF extraction.
The `mvt-android check-backup` command can also be used directly with an Android backup file.
The Mobile Verification Toolkit team welcomes contributions of new forensic modules or other contributions which help improve the software.
## Testing
MVT uses `pytest` for unit and integration tests. Code style consistency is maintained with `flake8`, `ruff` and `black`. All can
be run automatically with:
```bash
make check
```
Run these tests before making new commits or opening pull requests.
## Profiling
Some MVT modules extract and process significant amounts of data during the analysis process or while checking results against known indicators. Care must be
take to avoid inefficient code paths as we add new modules.
MVT modules can be profiled with Python built-in `cProfile` by setting the `MVT_PROFILE` environment variable.

Using Docker simplifies having all the required dependencies and tools (including most recent versions of [libimobiledevice](https://libimobiledevice.org)) readily installed. Note that this requires a Linux host, as Docker for Windows and Mac [doesn't support passing through USB devices](https://docs.docker.com/desktop/faqs/#can-i-pass-through-a-usb-device-to-a-container).
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:
Once Docker is installed, you can run MVT by downloading a prebuilt MVT Docker image, or by building a Docker image yourself from the MVT source repo.
### Using the prebuilt Docker image
```bash
docker pull ghcr.io/mvt-project/mvt
```
You can then run the Docker container with:
```
docker run -it ghcr.io/mvt-project/mvt
```
### Build and run Docker image from source

git clone https://github.com/mvt-project/mvt.git

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`:
```bash
docker run -it --device=/dev/<your_usb_port> mvt
```
If a prompt is spawned successfully, you can close it with `exit`.
Mobile Verification Toolkit (MVT) is a tool to facilitate the [consensual forensic analysis](introduction.md#consensual-forensics) of Android and iOS devices, for the purpose of identifying traces of compromise.
It has been developed and released by the [Amnesty International Security Lab](https://securitylab.amnesty.org) in July 2021 in the context of the [Pegasus Project](https://forbiddenstories.org/about-the-pegasus-project/) along with [a technical forensic methodology](https://www.amnesty.org/en/latest/research/2021/07/forensic-methodology-report-how-to-catch-nso-groups-pegasus/). It continues to be maintained by Amnesty International and other contributors.
In this documentation you will find instructions on how to install and run the `mvt-ios` and `mvt-android` commands, and guidance on how to interpret the extracted results.
*libusb-1.0-0* is not required if you intend to only use `mvt-ios` and not `mvt-android`.
(Recommended) Set up `pipx`
For Ubuntu 23.04 or above:
```bash
sudo apt install pipx
pipx ensurepath
```
For Ubuntu 22.04 or below:
```
python3 -m pip install --user pipx
python3 -m pipx ensurepath
```
Other distributions: check for a `pipx` or `python-pipx` via your package manager.
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.

## Installing MVT
If you haven't done so, you can add this to your `.bashrc` or `.zshrc` file in order to add locally installed Pypi binaries to your `$PATH`:
### Installing from PyPI with pipx (recommended)
1. Install `pipx` following the instructions above for your OS/distribution. Make sure to run `pipx ensurepath` and open a new terminal window.
2. ```bash
pipx install mvt
```
You now should have the `mvt-ios` and `mvt-android` utilities installed. If you run into problems with these commands not being found, ensure you have run `pipx ensurepath` and opened a new terminal window.
### Installing from PyPI directly into a virtual environment
You can use `pipenv`, `poetry` etc. for your virtual environment, but the provided example is with the built-in `venv` tool:
1. Create the virtual environment in a folder in the current directory named `env`:
```bash
export PATH=$PATH:~/.local/bin
python3 -m venv env
```
Then you can install MVT directly from [pypi](https://pypi.org/project/mvt/)
2. Activate the virtual environment:
```bash
pip3 install mvt
source env/bin/activate
```
Or from the source code:
3. Install `mvt` into the virtual environment:
```bash
pip install mvt
```
The `mvt-ios` and `mvt-android` utilities should now be available as commands whenever the virtual environment is active.
### Installing from git source with pipx
If you want to have the latest features in development, you can install MVT directly from the source code in git.
You now should have the `mvt-ios` and `mvt-android` utilities installed.
**Notes:**
1. The `--force` flag is necessary to force the reinstallation of the package.
2. To revert to using a PyPI version, it will be necessary to `pipx uninstall mvt` first.
