# Contributing to Mobile Verification Toolkit (MVT)
# Contributing
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.**
Thank you for your interest in contributing to Mobile Verification Toolkit (MVT)! Your help is very much appreciated.
2. **Suggest features:**
- If you have an idea for new functionality, create a feature request issue and describe your proposal.
## Where to start
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.
Starting to contribute to a somewhat complex project like MVT might seem intimidating. Unless you have specific ideas of new functionality you would like to submit, some good starting points are searching for `TODO:` and `FIXME:` comments throughout the code. Alternatively you can check if any GitHub issues existed marked with the ["help wanted"](https://github.com/mvt-project/mvt/issues?q=is%3Aissue+is%3Aopen+label%3A%22help+wanted%22) tag.
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.
When contributing code to
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.
- **Indentation**: we use 4-spaces tabs.
Please check your code before opening a pull request by running `make ruff`
- **Quotes**: we use double quotes (`"`) as a default. Single quotes (`'`) can be favored with nested strings instead of escaping (`\"`), or when using f-formatting.
## 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.
- **Maximum line length**: we strongly encourage to respect a 80 characters long lines and to follow [PEP8 indentation guidelines](https://peps.python.org/pep-0008/#indentation) when having to wrap. However, if breaking at 80 is not possible or is detrimental to the readability of the code, exceptions are tolerated. For example, long log lines, or long strings can be extended to 100 characters long. Please hard wrap anything beyond 100 characters.

# Deprecation of ADB command in MVT
# Check over ADB
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.
The `mvt-android check-adb` command has been deprecated and removed from MVT.
## Connecting over Wi-FI
The ability to analyze Android devices over ADB (`mvt-android check-adb`) has been removed from MVT due to several technical and forensic limitations.
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:
## Reasons for Deprecation
```bash
adb tcpip 5555
```
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.
Then you can specify the IP address of the phone with the adb port number to MVT like so:
2. **Incomplete Forensic Data Acquisition**
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.
```bash
mvt-android check-adb --serial 192.168.1.20:5555 --output /path/to/results
```
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.
Where `192.168.1.20` is the correct IP address of your device.
5. **Alignment with iOS Workflow**
MVTs 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.
## MVT modules requiring root privileges
## 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)
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!

# Methodology for Android forensic
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.
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.
However, not all is lost.
## Check Android devices with AndroidQF and MVT
## Check installed Apps
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.
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.
### Why Use AndroidQF?
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 look them up on services such as [VirusTotal](https://www.virustotal.com).
- **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).
!!! info "Using VirusTotal"
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.
## Check the device over Android Debug Bridge
The ability to analyze Android devices over ADB (`mvt-android check-adb`) has been removed from MVT.
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.
See the [Android ADB documentation](./adb.md) for more information.
## 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.
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.
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.

git clone https://github.com/mvt-project/mvt.git
cd mvt
pip3 install .
```
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.
