Donncha Ó Cearbhaill 1b03002a00 Major refactor to add structured alerting and typed indicators
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.

## Usage
MVT provides three commands: `mvt-ios` and `mvt-android` analyse acquisitions from devices of that platform, and `mvt` hosts what belongs to neither: `version`, `completion`, `plugins` and `download-iocs` (`version` and `download-iocs` remain available on the platform commands for now). Running `mvt` on its own shows the installed version, update notices and the available commands. [Check out the documentation to learn how to use them!](https://docs.mvt.re/)
Pass `--verbose` to any of the three commands, before the command name (`mvt-ios --verbose check-backup ...`), for debug output. The `--verbose` option the `check-*` commands accept after their name still works but is kept for compatibility only and will be removed in a future release.
### Shell completion
MVT can generate a shell completion script for Bash, Zsh, and Fish which covers `mvt`, `mvt-ios` and `mvt-android`:
```bash
mvt completion
```
The command prints setup instructions by default. To generate the completion script directly, pass the shell name:
```bash
mvt completion bash
```
MVT only writes completion files or shell configuration when `--install` is passed. See the [command completion documentation](https://docs.mvt.re/en/latest/command_completion/) for details.
Plugin packages extend MVT with additional forensic modules, which run inside
the `check-*` commands, and with top-level commands on `mvt`, `mvt-ios` and
`mvt-android`. See the
[development documentation](https://docs.mvt.re/en/latest/development/) for
writing and installing them, and the
[custom CLI command documentation](https://docs.mvt.re/en/latest/development/custom_commands/)
for the entry points a package registers commands in.
MVT provides two commands `mvt-ios` and `mvt-android`. [Check out the documentation to learn how to use them!](https://docs.mvt.re/)

# ADB Analysis Removed
# Check over ADB
The ability to analyze Android devices directly over the [Android Debug Bridge (adb)](https://developer.android.com/studio/command-line/adb) has been removed from MVT.
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.
Use [AndroidQF](https://github.com/mvt-project/androidqf) to collect forensic artifacts from an Android device, then analyze the collected output with:
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-androidqf /path/to/androidqf-output
mvt-android check-adb --output /path/to/results
```
For a standalone Android bug report, use:
!!! warning
The `check-adb` command is deprecated and will be removed in a future release.
Whenever possible, prefer acquiring device data using the AndroidQF project (https://github.com/mvt-project/androidqf/) and then analyze those acquisitions with MVT.
```bash
mvt-android check-bugreport /path/to/bugreport.zip
```
Running `mvt-android check-adb` will also emit a runtime deprecation warning advising you to migrate to AndroidQF.
## Reasons for Removal
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
The `mvt-android check-adb` command has been deprecated and removed from MVT.
The ability to analyze Android devices over ADB (`mvt-android check-adb`) has been removed from MVT due to several technical and forensic limitations.
## Reasons for Deprecation
1. **Inconsistent Data Collection Across Devices**
Android devices vary significantly in system architecture, security policy, and diagnostic log availability. This made it difficult to collect reliable forensic data 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.
2. **Incomplete Forensic Data Acquisition**
Direct ADB analysis did not retrieve a complete forensic snapshot. Critical artifacts such as full bug reports could be missing.
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.
3. **Duplicated Analysis Paths**
Similar artifacts were parsed through separate ADB, AndroidQF, and bugreport modules, which made behavior harder to keep consistent.
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.
4. **Workflow Consistency**
MVT now focuses on analyzing acquired artifacts rather than interacting with live devices directly.
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.
## 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)

# Downloading APKs from an Android phone
MVT allows you to attempt to download all available installed packages (APKs) from a device 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:
```bash
mvt-android download-apks --output /path/to/folder
```
It might take several minutes to complete.
!!! info
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). While these lookups do not provide any conclusive assessment on all of the extracted APKs, they might highlight any known malicious ones:
```bash
MVT_VT_API_KEY=<key> mvt-android download-apks --output /path/to/folder --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.
In case you have a previous extraction of APKs you want to later check against VirusTotal, you can do so with the following arguments:
```bash
MVT_VT_API_KEY=<key> mvt-android download-apks --from-file /path/to/folder/apks.json --virustotal

# Check Android Intrusion Logs
Recent versions of Android can produce structured *Intrusion Logs* — newline-delimited JSON records derived from the platform's [SecurityLog API](https://developer.android.com/reference/android/app/admin/SecurityLog). Intrusion Logging is offered as a new option under Android's **Advanced Protection Mode**, which users can opt into on their device; no MDM or device-policy configuration is required. When enabled, these logs provide a high-fidelity record of process starts, DNS queries, outbound network connections, ADB activity, keyguard events, and other security-relevant operations. The initial Intrusion Logging feature was released for Android 16 in May 2026. The feature and supported events is likely to be expanded over time.
For background on how this data source was introduced and why it is forensically valuable, see the Amnesty International Security Lab announcement: [Android Intrusion Logging as a new source of data for consensual forensic analysis](https://securitylab.amnesty.org/latest/2026/05/android-intrusion-logging-as-a-new-source-of-data-for-consensual-forensic-analysis/).
## Recommended workflow: collect with AndroidQF
[AndroidQF](https://github.com/mvt-project/androidqf) is the recommended way to acquire data from an Android device for analysis with MVT. During acquisition AndroidQF will prompt the user to also collect intrusion logs from the device, and writes them into an `intrusion-logs/` subdirectory of the acquisition output.
When you analyse such an acquisition with `mvt-android check-androidqf`, MVT automatically detects the `intrusion-logs/` directory and runs the same intrusion-log checks described below — there is no need to invoke a separate command:
```bash
mvt-android check-androidqf --output /path/to/results/ /path/to/androidqf-output/
```
The device timezone is read from the AndroidQF acquisition (`getprop.txt`) and applied to event timestamps automatically.
## Standalone command: `check-intrusion-logs`
The `mvt-android check-intrusion-logs` command runs the intrusion-log analysis directly against a set of log files. Prefer the AndroidQF workflow above; use the standalone command when the intrusion logs were collected outside of an AndroidQF acquisition, or when re-analysing only a set of intrusion logs.
## Expected input
`check-intrusion-logs` accepts either:
- a **directory** containing one or more `.txt` files (recursively), or
- a **`.zip` archive** containing such `.txt` files (nested `.zip` archives are also walked).
Each `.txt` file is expected to contain newline-delimited JSON, with one JSON object per line. Each object wraps a single event under a top-level key indicating its type, for example:
```json
{"dns_event": {"event_time": 1746979200000, "hostname": "example.com", "ip_addresses": ["93.184.216.34"], "package_name": "com.example.app"}}
{"connect_event": {"event_time": 1746979201000, "ip_address": "93.184.216.34", "port": 443, "package_name": "com.example.app"}}
{"security_event": {"event_time": 1746979202000, "tag": 210005, "data": ["..."]}}
```
Identical events that appear across multiple overlapping log files (e.g. daily rotations) are de-duplicated on a first-seen basis.
## Running the analysis
```bash
mvt-android check-intrusion-logs --output /path/to/results/ /path/to/intrusion-logs/
```
A `.zip` archive can be passed directly in place of the directory:
```bash
mvt-android check-intrusion-logs --output /path/to/results/ /path/to/intrusion-logs.zip
```
### Options
| Option | Description |
| --- | --- |
| `-i, --iocs PATH` | Path to a STIX2 indicator file. May be passed multiple times. |
| `-o, --output PATH` | Directory where JSON results and the timeline CSV will be written. |
| `-l, --list-modules` | List the available intrusion-log modules and exit. |
| `-m, --module NAME` | Run a single module (e.g. `DnsEvent`) instead of all of them. |
| `-t, --timezone TZ` | IANA timezone name for the device (e.g. `Europe/Paris`). When set, event timestamps are converted to the device's local time instead of UTC. |
| `-v, --verbose` | Verbose logging. Kept for compatibility and to be removed in a future release: pass `--verbose` to `mvt-android` itself instead. |
## Modules
The command runs the following modules over the parsed events:
- **`DnsEvent`** — DNS resolution events. Hostnames and resolved IP addresses are checked against domain indicators, and the requesting `package_name` is checked against app-identifier indicators.
- **`ConnectEvent`** — Outbound network connection events. Destination IPs (with localhost addresses skipped) are checked against domain indicators, and `package_name` is checked against app-identifier indicators.
- **`SecurityEvent`** — Security log events keyed by Android `SecurityLog` tag IDs (e.g. `app_process_start`, `adb_shell_cmd`, `keyguard_dismissed`, `os_startup`, `cert_*` events). These are surfaced in the timeline to help reconstruct device activity around suspected events.
All three modules share a single pre-parsing pass over the input, so adding more modules in the future does not multiply I/O cost. Additional modules will be added in the future to support new event types which are generated by the Intrusion Logging feature.
## Interpreting results
A successful IOC match raises a `CRITICAL` alert that includes the matched indicator, the offending event, and the event timestamp. Alerts are summarised at the end of the run and persisted alongside the per-module JSON results.
When `--timezone` is provided, timestamps in the timeline and JSON output reflect the device's local wall-clock time. Otherwise timestamps are in UTC, consistent with the rest of MVT.
## Limitations
- This page assumes the intrusion logs have already been collected from the device. The recommended collection path is via AndroidQF (see above); intrusion logging itself must have been enabled on the device beforehand by opting into Android's Advanced Protection mode and also enabling the optional Intrusion Logging feature (see the [Amnesty blog post](https://securitylab.amnesty.org/latest/2026/05/android-intrusion-logging-as-a-new-source-of-data-for-consensual-forensic-analysis/) for details).
- As with all IOC-based analysis, public indicators alone are not sufficient to conclude that a device is uncompromised. See the [Indicators of Compromise](../iocs.md) page for context.

### VirusTotal package lookups
## Check the device over Android Debug Bridge
AndroidQF records APK file hashes in `packages.json`. MVT can optionally look up non-system APK hashes on VirusTotal while checking an AndroidQF acquisition:
The ability to analyze Android devices over ADB (`mvt-android check-adb`) has been removed from MVT.
```bash
MVT_VT_API_KEY=<key> mvt-android check-androidqf --virustotal /path/to/androidqf-output
```
The `--virustotal` option is disabled by default because it sends APK hashes to VirusTotal and requires network access. It uses the `VT_API_KEY` MVT configuration value, which can also be provided through the `MVT_VT_API_KEY` environment variable.
To avoid exhausting free VirusTotal API quotas, MVT waits 16 seconds between package hash requests by default. Use `--delay` to change the delay, or `--delay 0` to disable throttling:
```bash
mvt-android check-androidqf --virustotal --delay 30 /path/to/androidqf-output
```
## Android Intrusion Logs
On devices where the user has opted into Android's [**Advanced Protection Mode**](https://support.google.com/android/answer/16339980) and turned on the optional Intrusion Logging featrue, Android can create and archive structured *Intrusion Logs* in an encrypted format. These logs record DNS queries, outbound network connections, process starts, ADB activity and other security-relevant events, and are a high-fidelity complement to the rest of an AndroidQF acquisition. The logs are generated on-device and encrypted before being stored in the Google account associated with the device. The encryption key is protected by the user device PIN. The intrusion log data is not accessible to Google.
AndroidQF will prompt the user to download, decrypt and collect device intrusion logs as part of an acquisition. When they are present, `mvt-android check-androidqf` will automatically run the intrusion-log checks alongside the other AndroidQF modules — no extra command is required. This is the recommended workflow for Android forensic analysis with MVT.
For cases where intrusion logs were collected outside of an AndroidQF acquisition, the standalone `mvt-android check-intrusion-logs` command can analyse them directly. See [Check Android Intrusion Logs](intrusion_logs.md) for details, and the [feature announcment from Amnesty International's Security Lab](https://securitylab.amnesty.org/latest/2026/05/android-intrusion-logging-as-a-new-source-of-data-for-consensual-forensic-analysis/) for background on the data source.
## Android Debug Bridge analysis removed
The ability to analyze Android devices directly over ADB has been removed from MVT. Direct extraction of data from ADB was error-prone and frequently resulted in inconsistent data collection between ADB and AndroidQF acquisitions. Use AndroidQF for device acquisition and `mvt-android check-androidqf` for analysis.
See the [Android ADB documentation](./adb.md) for more information.

MVT utilizes the [Click](https://click.palletsprojects.com/en/stable/) library for creating its command line interface.
Click provides tab completion support for Bash (version 4.4 and up), Zsh, and Fish.
To enable it, you need to register a completion script with your shell, which varies depending on the shell you are using.
To enable it, you need to manually register a special function with your shell, which varies depending on the shell you are using.
`mvt completion` generates one script which covers `mvt`, `mvt-ios` and `mvt-android`. The following describes how to generate that script and add it to your shell configuration.
The following describes how to generate the command completion scripts and add them to your shell configuration.
> **Note: You will need to start a new shell for the changes to take effect.**
### For Bash
```bash
# Generate the bash completion script
mvt completion bash > ~/.mvt-complete.bash
# Generates bash completion scripts
echo "$(_MVT_IOS_COMPLETE=bash_source mvt-ios)" > ~/.mvt-ios-complete.bash &&
echo "$(_MVT_ANDROID_COMPLETE=bash_source mvt-android)" > ~/.mvt-android-complete.bash
```
Add the following to `~/.bashrc`:
```bash
# source the mvt completion script
[ -f ~/.mvt-complete.bash ] && . ~/.mvt-complete.bash
# source mvt completion scripts
. ~/.mvt-ios-complete.bash && . ~/.mvt-android-complete.bash

mvt completion zsh > ~/.mvt-complete.zsh
# Generates zsh completion scripts
echo "$(_MVT_IOS_COMPLETE=zsh_source mvt-ios)" > ~/.mvt-ios-complete.zsh &&
echo "$(_MVT_ANDROID_COMPLETE=zsh_source mvt-android)" > ~/.mvt-android-complete.zsh
```
Add the following to `~/.zshrc`:
```bash
# source the mvt completion script
[ -f ~/.mvt-complete.zsh ] && . ~/.mvt-complete.zsh
# source mvt completion scripts
. ~/.mvt-ios-complete.zsh && . ~/.mvt-android-complete.zsh
```
### For Fish
```bash
# Generate the fish completion script
mkdir -p ~/.config/fish/conf.d
mvt completion fish > ~/.config/fish/conf.d/mvt-completion.fish
```
Fish loads the files in `~/.config/fish/conf.d` automatically.
### Automatic Installation
MVT can write the completion file and update the relevant shell configuration for Bash and Zsh when you pass `--install`:
```bash
mvt completion bash --install
```
Replace `bash` with `zsh` or `fish` as needed. For Fish, `--install` writes the completion file into `~/.config/fish/conf.d` and changes no shell configuration.
!!! note
Earlier versions generated one script per command, with `mvt-ios completion`
and `mvt-android completion`. Files written by them keep working. When you
switch to the single script, remove the old files and the lines which load
them from your shell configuration.

# Development
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.
```bash
MVT_PROFILE=1 dev/mvt-ios check-backup test_backup
```

# Custom CLI Commands
MVT can load additional top-level commands into `mvt`, `mvt-ios` and
`mvt-android`. A command package chooses which of the three each of its
commands is added to.
Custom commands are different from [custom forensic modules](index.md#custom-modules):
commands add new CLI operations, while modules add analysis steps to existing
`check-*` commands.
!!! warning
Custom commands run as trusted Python code inside the MVT process. Install
or load commands only from sources you trust. MVT does not sandbox
third-party commands, and the MVT maintainers do not maintain them.
## Install a Command Package
Python packages can register a Click command or group on one or more of the MVT CLIs.
A minimal package can expose this command from `my_mvt_plugin.py`:
```python
import click
@click.command()
@click.argument("path", type=click.Path(exists=True))
def summarize(path):
"""Summarize an acquisition."""
click.echo(f"Summarizing {path}")
```
Log through `get_plugin_logger(__name__)` from `mvt.plugin`. Records logged
through `logging.getLogger(__name__)` do not reach `command.log`, and MVT's
console handler does not show them.
Register the object in the package's `pyproject.toml`. The entry-point name is
the command users invoke:
```toml
[project.entry-points."mvt.ios.cli_plugins"]
summarize = "my_mvt_plugin:summarize"
[project.entry-points."mvt.android.cli_plugins"]
summarize = "my_mvt_plugin:summarize"
```
Each entry-point group adds the command to one CLI: `mvt.ios.cli_plugins` to
`mvt-ios`, `mvt.android.cli_plugins` to `mvt-android` and `mvt.cli_plugins` to
`mvt`. Register the command in the group of every CLI which should offer it: a
platform-specific command belongs in one platform group, and a command which
handles acquisitions of both platforms, as above, in both. After installing the
package in the same environment as MVT, the command appears directly in those
CLIs:
```bash
mvt-ios summarize ./ios-backup
mvt-android summarize ./androidqf-output
```
For a `pipx` installation of MVT, inject the plugin into MVT's environment:
```bash
pipx inject mvt my-mvt-plugin
```
When MVT is installed in an active virtual environment, install the plugin with
`pip` in that environment. `mvt plugins list` shows the installed packages and
the commands they add, see [Managing Plugins](plugins.md).
Command packages that need their own settings, such as an API key, should store
them in a namespaced [plugin configuration file](plugin_configuration.md)
rather than in MVT's own `config.yaml`.
### Commands on `mvt`
A MVT plugin command can also add sub-commands to the base `mvt` command. This can be used for commands which are not tied to a particular forensic platform:
```toml
[project.entry-points."mvt.cli_plugins"]
my-plugin = "my_mvt_plugin:my_plugin"
```
Commands in this group are added to `mvt` only, so this one is invoked as
`mvt my-plugin`. A command on `mvt` has nothing but its name to say which
plugin it belongs to, so name it after the plugin, and make it a Click group
when the plugin has several operations to offer, such as
`mvt my-plugin configure`.
## Developing a Command Locally
A package is how a command is distributed. While a command is being written,
MVT can load it straight from its file instead, so the package need not be
reinstalled after every change; an editable install of the package does the
same through its entry points. Create a Python file that exports one Click
command or group named `cli`:
```python
import click
@click.command("case-summary")
@click.argument("path", type=click.Path(exists=True))
def cli(path):
"""Summarize a case directory."""
click.echo(f"Summarizing {path}")
```
Pass the file before the custom command name:
```bash
mvt-ios --load-command ./case_summary.py case-summary ./ios-backup
```
`--load-command` can be repeated and also accepts a folder. MVT loads
non-hidden top-level `*.py` files in sorted order and skips `__init__.py`.
Every loaded file must export one `cli` object.
To load a file or folder on every invocation, set the environment variable of
the CLI the commands belong on. Like the entry-point groups, each variable adds
its commands to one CLI only:
```bash
export MVT_CUSTOM_COMMANDS=./commands
export MVT_IOS_CUSTOM_COMMANDS=./ios_commands
export MVT_ANDROID_CUSTOM_COMMANDS=./android_commands
```
## Building a Module-Running Command
A command which runs forensic modules over an acquisition subclasses `Command`.
`Command` creates the output folder and writes `command.log`. It orders the
modules, resolves their dependencies and runs them. It writes the result files,
`alerts.json` and `info.json`. The subclass sets `platform`, `name` and
`modules`:
```python
from mvt.plugin import Command, MVTModule, convert_unix_to_iso, get_plugin_logger
log = get_plugin_logger(__name__)
class APKManifest(MVTModule):
supported_commands = (("android", "check-apks"),)
def run(self):
self.results = [{"checked_at": convert_unix_to_iso(0)}]
class CmdCheckAPKs(Command):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.platform = "android"
self.name = "check-apks"
self.modules = [APKManifest]
```
`platform` and `name` are the pair the modules declare in
`supported_commands`. `modules` lists the module classes the command runs,
imported directly. A command which runs modules of another plugin depends on
that package in `pyproject.toml` and imports them the same way. `init()`,
`module_init(module)` and `finish()` are optional hooks. `run()` calls them
before the run, before each module and after the run.
Wrap the command in a Click command with an `--output` option. Run it, then
print the alert summary:
```python
import click
@click.command("check-apks")
@click.option("--output", "-o", type=click.Path(exists=False))
@click.argument("TARGET_PATH", type=click.Path(exists=True))
def cli(output, target_path):
cmd = CmdCheckAPKs(target_path=target_path, results_path=output)
log.info("Checking APK files at path: %s", target_path)
cmd.run()
cmd.show_alerts_brief()
```
The `--verbose` option of `mvt`, `mvt-ios` and `mvt-android` applies to the
command. The command defines no `--verbose` option of its own. The pair a
plugin command adds is not listed anywhere in MVT. Name it in the plugin's
README.
## Naming and Errors
Built-in MVT commands cannot be replaced. External command names must also be
unique on each CLI; when installed packages or environment paths collide, MVT
keeps the first command and logs a warning. The environment path of a CLI is
registered before its installed packages, so a command loaded from there wins a
collision with a package. A collision from an explicit `--load-command` is a
usage error.
A package entry point or environment command that cannot be imported appears
as a marked broken command without preventing other MVT commands from working.
Invoke that command to see its package or file source and the underlying error.
An invalid command supplied explicitly with `--load-command` fails immediately
with a usage error.
Installed command packages use the entry-point name as the CLI command name.
The entry point must resolve to a `click.Command` or `click.Group`.

# Development
The Mobile Verification Toolkit team welcomes contributions of new forensic modules or other contributions which help improve the software.
## Local environment
MVT uses `uv` for dependency management. To install the project and development dependencies from the locked environment, run:
```bash
make install
```
## Testing
MVT uses `pytest` for unit and integration tests. Code style consistency is maintained with `ruff` and `mypy`. All can
be run automatically with:
```bash
make check
```
Run these tests before making new commits or opening pull requests.
## Module dependencies
Modules can require other modules to run first by declaring their classes in
`dependencies`. The command runner uses a stable topological ordering, so the
existing module list order is preserved wherever dependency constraints allow.
```python
class DependentModule(MVTModule):
dependencies = (PrerequisiteModule,)
def run(self):
prerequisite_results = self.get_dependency_results(PrerequisiteModule)
```
Selecting a single module also runs its transitive dependencies.
A module can only depend on modules the command it runs in also has. When a
declared dependency is not among them, the command logs a warning naming the
module and the missing dependency, skips that module and everything depending
on it, and runs the rest of the analysis. Selecting such a module with
`--module` therefore leaves nothing to run, which the warning explains.
A cycle in the dependency graph is a programming error rather than a
configuration problem: the command logs a warning and runs no modules at all.
## Custom modules
MVT's module-running `check-*` commands can run forensic modules which are not
part of MVT. Custom modules are distributed as plugin packages. A Python
package installed next to MVT registers its modules through an entry point.
The modules then load automatically in every command they support, see
[Installed module packages](#installed-module-packages). `mvt plugins list`
shows the installed packages and where each one was installed from.
MVT can also load module files by path, with `--load-module` and
`MVT_CUSTOM_MODULES`, see
[Developing modules locally](#developing-modules-locally). This can be used
while writing a module. Use a Python package to distribute one.
A custom module declares in `supported_commands` the platform and command
pairs it runs in. A module with empty `supported_commands` does not run and
MVT logs a warning. The nine pairs are:
```python
("ios", "check-backup")
("ios", "check-fs")
("ios", "check-iocs")
("ios", "check-sysdiagnose")
("android", "check-backup")
("android", "check-bugreport")
("android", "check-androidqf")
("android", "check-intrusion-logs")
("android", "check-iocs")
```
`check-iocs` re-checks stored results rather than an acquisition. It matches
every `<slug>.json` file in the results folder to the module with that slug.
It then runs that module's `check_indicators()` again. A module which
implements `check_indicators()` is included in `check-iocs` for its platform.
It does not need to declare the `check-iocs` pair.
### Writing a module
A module subclasses `MVTModule` or one of the base classes below and
implements `run()`. `check_indicators()` and `serialize()` are optional. The
first matches results against IOCs or detections. The second returns timeline
records.
```python
from mvt.plugin import IOSExtraction, convert_unix_to_iso
class ExampleCustomModule(IOSExtraction):
supported_commands = (
("ios", "check-backup"),
("ios", "check-fs"),
)
slug = "example_custom_module"
def run(self):
self.results = [{"checked_at": convert_unix_to_iso(0)}]
def check_indicators(self):
pass
def serialize(self, result):
return None
```
The base classes are:
- `MVTModule`: the base of every module. It provides `self.results`,
`self.alertstore`, `self.log`, `self.indicators` and
`get_dependency_results()`. Subclass it directly for a module which reads
only the results of other modules.
- `IOSExtraction`: `("ios", "check-backup")` and `("ios", "check-fs")`. Adds
`_find_ios_database()`, which locates a module's database in a backup or in
a filesystem dump and repairs it if it is malformed. Adds
`_get_backup_files_from_manifest()`, `_get_backup_file_from_id()` and
`_get_fs_files_from_patterns()`. Adds `_open_sqlite_db()`, which opens a
database read-only.
- `SysdiagnoseExtraction`: `("ios", "check-sysdiagnose")`. MVT extracts the
archive and calls `from_sysdiagnose_folder()` before `run()`. The module
reads files with `_get_files_by_pattern()` and `_get_file_content()`.
`ips_files` lists the crash reports. See
[Check an iOS Sysdiagnose](../ios/sysdiagnose.md).
- `AndroidQFModule`: `("android", "check-androidqf")`. MVT calls `from_dir()`
or `from_zip()` with the file list of the acquisition. The module reads
files with `_get_files_by_pattern()` and `_get_file_content()`.
`_get_device_timezone()` returns the device timezone.
- `AndroidBackupModule`: `("android", "check-backup")`. MVT calls `from_dir()`
or `from_ab()`. The module reads files with `_get_files_by_pattern()` and
`_get_file_content()`.
- `BugReportModule`: `("android", "check-bugreport")`. MVT calls `from_dir()`
or `from_zip()`. The module reads files with `_get_files_by_pattern()`,
`_get_files_by_patterns()` and `_get_file_content()`.
`_get_dumpstate_file()` returns the dumpstate file, and
`_get_file_modification_time()` the modification time of a file.
The underscore-named helpers are internal to the base classes. Plugin modules
can call them. Their names and signatures can change between releases. Read
the base class in `src/mvt/ios/modules` or `src/mvt/android/modules` before
relying on one.
### Depending on a built-in module
A module which post-processes records generated by one or more built-in MVT
modules must declare the source modules in `dependencies`. It reads their
results with `get_dependency_results()`. Import the class from its family
package: `mvt.ios.modules.backup`, `mvt.ios.modules.fs`,
`mvt.ios.modules.mixed`, `mvt.android.modules.androidqf`,
`mvt.android.modules.backup`, `mvt.android.modules.bugreport` or
`mvt.android.modules.intrusion_logs`.
```python
from mvt.ios.modules.backup import Manifest
from mvt.plugin import MVTModule
class DependentCustomModule(MVTModule):
supported_commands = (("ios", "check-backup"),)
dependencies = (Manifest,)
def run(self):
manifest_results = self.get_dependency_results(Manifest)
self.results = [{"manifest_entries": len(manifest_results)}]
```
Dependencies are ordered as for the built-in modules, with custom modules
appended after the built-ins, see [Module dependencies](#module-dependencies).
A dependency has to run in every command the module supports. Where it does
not, MVT skips the module with a warning.
`get_dependency_results()` returns the plain dictionaries the module produced.
They are the same records it writes to `<slug>.json`. Typed results per module
are planned.
### Replacing a built-in module
A custom module which extends a built-in one runs alongside it, and when the
two share a slug they write to the same results file. MVT warns about that
collision, naming both modules, where each came from and the file the later one
overwrites, but it runs them both. Set `replaces` to the class the module
supersedes to take that module's place instead: when both are available to a
command, the named module is dropped from the run.
```python
from mvt.ios.modules.backup import Manifest as BuiltinManifest
class Manifest(BuiltinManifest):
supported_commands = (("ios", "check-backup"),)
replaces = BuiltinManifest
```
Keeping the class name of the replaced module, as above, keeps the name
`--module` selects the module by and the slug its results file is named after.
A replacement with a different class name writes to a file named after its own
slug, unless it sets `slug` to the slug of the module it replaces, and
`--module` still selects it by the name of the replaced module, which MVT logs.
Taking over the slug of a replaced module is not a collision and is not warned
about, because that module is no longer part of the run.
Modules which depend on the replaced module receive the replacement instead, so
`get_dependency_results(BuiltinManifest)` returns the replacement's results. A
module must not depend on the module it replaces: that module does not run, so
the replacement has to produce the data itself, and MVT logs a warning when a
module declares both.
A replacement takes on the obligations of the module it replaces. If it
declares a dependency the command does not provide, it is skipped like any
other module with an unavailable dependency, and the module it replaced stays
out of the run: neither of them produces results, and the modules depending on
the replaced module are skipped as well.
Subclassing the replaced module is not required, but a replacement which is not
a subclass is logged with a warning, because its results may not be what the
modules depending on the replaced module expect. Naming a module the command
does not run has no effect, and modules which replace each other in a cycle all
keep running and replace nothing. Every applied substitution is logged, so it
is recorded in `command.log` when the command runs with an `--output` folder.
Every command resolves replacements on its own. `check-iocs` matches stored
results files against the slugs of the modules available for that command. A
replacement which subclasses the module it replaces inherits its
`check_indicators()`. It is then part of `check-iocs` for its platform and
re-checks the results file named after its slug. A replacement with no
`check_indicators()` is not part of `check-iocs`. The built-in module it
replaced re-checks the file. `check-iocs` matches `--module` on the class name
only. Pass a differently named replacement's own name there, not the name of
the module it replaces.
### Importing from MVT
Import from `mvt.plugin` if it has what you need. The names it exports are
kept working on a best-effort basis. A change to one of them is announced in
the release notes. Anything else in `mvt` can be imported too, but may change
between releases without notice. The plugin interface is best effort.
`mvt.plugin` exports the base classes above and `Command`, `Alert` and
`AlertLevel`, the result types, `DatabaseNotFoundError` and
`DatabaseCorruptedError`, the timestamp converters, the settings API of
[Plugin Configuration](plugin_configuration.md), MVT's own `settings`,
`get_plugin_logger()` and `MVT_VERSION`. `src/mvt/plugin.py` holds the list.
Read MVT's `settings` for values such as `NETWORK_ACCESS_ALLOWED` and
`NETWORK_TIMEOUT`. Plugin values go in the plugin's own settings file.
## Installed module packages
Python packages can register modules so they load automatically in every
module-running `check-*` command, without `--load-module` or
`MVT_CUSTOM_MODULES`. Register an entry point in the `mvt.modules` group in
the package's `pyproject.toml`:
```toml
[project.entry-points."mvt.modules"]
mvt-plugin-example-org = "mvt_plugin_example_org:get_modules"
```
The entry point must resolve to an iterable of `MVTModule` subclasses, or to
a callable returning one:
```python
from mvt.plugin import MVTModule
class PackagedModule(MVTModule):
supported_commands = (("ios", "check-backup"),)
def run(self):
self.results = [{"message": "packaged module ran"}]
def get_modules() -> list[type[MVTModule]]:
return [PackagedModule]
```
`get_modules()` is the package's module list, written by hand. A package which
keeps its modules in separate files imports each class there and lists it. A
module missing from the list does not load.
Installed modules follow the same rules as other custom modules: each module
must declare `supported_commands`, and dependencies are resolved with the
standard ordering logic. A broken entry point is skipped with a warning and
does not prevent MVT from running. As with custom commands, installed module
packages run as trusted code inside the MVT process, so install only packages
from sources you trust.
For a `pipx` installation of MVT, inject the package into MVT's environment:
```bash
pipx inject mvt mvt-plugin-example-org
```
Module packages that need their own settings, such as an API key, should store
them in a namespaced [plugin configuration file](plugin_configuration.md)
rather than in MVT's own `config.yaml`.
### Naming module packages
Name module packages `mvt-plugin-<name>` (import package `mvt_plugin_<name>`),
and include the name of the publishing organization or author so packages from
different groups do not collide: for example, an organisation's custom modules
would be distributed as `mvt-plugin-example-org` with the import package
`mvt_plugin_example_org`.
The prefix makes module packages easy to find on PyPI and keeps their import
names from clashing with unrelated Python packages. It is a convention, not a
technical requirement: modules load through the `mvt.modules` entry point
regardless of what the package is called, and existing packages with other
names keep working. Note that the prefix is also not a mark of authenticity —
anyone can publish a package with any available name, so vet a module package
and its publisher before installing it, whatever it is called.
### Module logging
Modules log through `self.log`, and MVT names the logger for where the module
came from. MVT's own modules log under their dotted path (for example
`mvt.ios.modules.mixed.whatsapp`). Everything external is namespaced under
`mvt.ext` to keep it visually distinct from built-in modules and isolated from
MVT's internal logger tree:
- Installed packages log under `mvt.ext.<package>`, with the `mvt_plugin_`
prefix stripped: modules in `mvt_plugin_example_org` log as
`mvt.ext.example_org.*`.
- Files loaded with `--load-module` or `MVT_CUSTOM_MODULES` log as
`mvt.ext.<file name>`.
Outside a module class, for example in a custom command line handler, log
through `get_plugin_logger(__name__)`. It returns a logger in the same
namespace.
## Developing modules locally
While a module is being written, load it from its file. `--load-module` takes a
Python file, or a folder of them, on every module-running command, and can be
repeated:
```bash
mvt-ios check-backup --load-module ./example_module.py --output ./out ./backup
```
For a folder, MVT loads its non-hidden top-level `*.py` files in sorted order
and skips `__init__.py`. `MVT_CUSTOM_MODULES` names a folder to load on every
module-running command, before any `--load-module` path:
```bash
MVT_CUSTOM_MODULES=./custom_modules mvt-android check-bugreport ./bugreport.zip
```
Files loaded this way follow the same rules as packaged modules.
`--list-modules` reports them with the SHA-256 hash of the file in place of a
version. An editable install of the package (`pip install -e .`) also works:
the modules load through the entry point, and `mvt plugins list` shows the
package with the `local` origin.
Loading by path is for development. Move a module into a package once it
works.
## Auditing loaded modules
Because installed module packages load automatically, MVT records where every
module came from:
- `--list-modules` groups the available modules by source: MVT itself
(with its version), each installed package (with its version and, when
installed directly from a repository, the commit), and each file loaded
with `--load-module` or `MVT_CUSTOM_MODULES` (with the SHA-256 hash of the
file).
- When a command runs with an `--output` folder, the `command.log` file
records one line per module source with the source's version or hash and
the list of modules loaded from it.
- `mvt plugins list` lists the installed packages, where each of them
was installed from and how many modules it contributes, see
[Managing Plugins](plugins.md).
## 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.
```bash
MVT_PROFILE=1 dev/mvt-ios check-backup test_backup
```
Open an issue or PR if you are encountering significant performance issues when analyzing a device with MVT.

# Plugin Configuration
Plugin packages that add [custom CLI commands](custom_commands.md) or
[modules](index.md#installed-module-packages) often need to store their
own settings, such as an API key, a server URL or the timestamp of the last
synchronization. MVT provides a namespaced settings base class so each plugin
keeps its configuration in its own file, and a data folder for anything else a
plugin needs to keep on disk.
!!! warning
Do not write plugin settings to MVT's own `config.yaml`. MVT rewrites that
file with the settings it knows about every time it starts, so any other
section is deleted.
## Where Settings Are Stored
Each plugin gets one YAML file in a `plugins` folder next to MVT's own
configuration:
```
~/.config/mvt/plugins/<plugin name>.yaml
```
The exact parent folder follows the platform convention used for MVT's
`config.yaml` (for example `~/Library/Application Support/mvt` on macOS). Use
`plugin_config_path()` from `mvt.plugin` instead of building the path by hand.
Plugin names must be lowercase and may only contain letters, digits and dashes,
matching the `mvt-plugin-<name>` package naming convention. MVT creates the
`plugins` folder with `0700` permissions and writes the settings files with
`0600` permissions, because they commonly hold credentials. Files are written
through a temporary file and moved into place, so an interrupted save never
leaves a partially written settings file behind.
## Plugin Data Folder
Everything else a plugin keeps on disk, such as a cache, a downloaded artifact
or synchronization state, belongs in the folder returned by the `data_folder()`
class method of the plugin's settings class, or by `plugin_data_folder()` from
`mvt.plugin`, called with the plugin name if the plugin has no settings class:
```
~/.local/share/mvt/plugin-data/<plugin name>/ # Linux
~/Library/Application Support/mvt/plugin-data/<plugin name>/ # macOS
```
The folder sits beside MVT's own data, such as the downloaded indicators. It is
created if it is missing, with `0700` permissions. Asking for it again returns
the same path and leaves the contents alone, so a plugin can ask for it every
time it needs the folder. `ExamplePluginSettings` below is the settings class
defined in the next section:
```python
import os
def cache_path() -> str:
folder = ExamplePluginSettings.data_folder()
return os.path.join(folder, "virustotal_lookups_cache.json")
```
A plugin which has no settings class calls
`plugin_data_folder("example-plugin")` instead.
Do not fall back on a path of your own such as `~/.cache/example-plugin`: it
is a Linux-only convention, and MVT will not create it for you.
## Defining Plugin Settings
Subclass `MVTPluginSettings`, set `plugin_name` and declare typed fields with
defaults:
```python
from typing import Optional
from mvt.plugin import MVTPluginSettings
class ExamplePluginSettings(MVTPluginSettings):
plugin_name = "example-plugin"
API_KEY: Optional[str] = None
MAX_RESULTS: int = 25
LAST_SYNC: Optional[str] = None
```
`load()` returns the current settings and `save()` writes them back:
```python
from datetime import datetime, timezone
import click
from mvt.plugin import plugin_env_prefix
def sync():
settings = ExamplePluginSettings.load()
if not settings.API_KEY:
prefix = plugin_env_prefix(settings.plugin_name)
raise click.ClickException(
f"No API key configured. Set {prefix}API_KEY or "
"run 'example-plugin configure'."
)
settings.LAST_SYNC = datetime.now(timezone.utc).isoformat()
settings.save()
```
The message builds the variable name with `plugin_env_prefix()`, see
[Environment Variables](#environment-variables).
A missing settings file is not an error: the plugin then runs on the field
defaults and on whatever the environment provides. `save()` only persists the
values that differ from the defaults, and it never touches MVT's `config.yaml`.
A settings file that cannot be parsed, or that does not hold a mapping of
setting names to values, raises a `PluginConfigLoadError` naming the file.
Every subclass that sets its own `plugin_name` gets its own file and its own
environment namespace. A subclass that does not redefine `plugin_name` inherits
it, and therefore shares the file and the environment variables of its parent
class.
## Environment Variables
Every field can also be set with an environment variable. The prefix is
`MVT_PLUGIN_`, followed by the plugin name upper-cased with dashes replaced by
underscores, followed by the field name. For the example above:
```bash
export MVT_PLUGIN_EXAMPLE_PLUGIN_API_KEY=...
export MVT_PLUGIN_EXAMPLE_PLUGIN_MAX_RESULTS=50
```
Do not repeat the plugin name in a field name: a plugin named `example-scanner`
with a `SCANNER_API_KEY` field asks the user for
`MVT_PLUGIN_EXAMPLE_SCANNER_SCANNER_API_KEY`. Name the field `API_KEY`.
Settings resolve in this order, from highest to lowest priority:
1. Arguments passed to the settings class directly, such as
`ExamplePluginSettings(API_KEY="...")`
2. Environment variables
3. The plugin's YAML file
4. The field defaults declared on the settings class
!!! tip
On shared or multi-user machines, prefer passing API keys through
environment variables rather than saving them to the plugin file. `save()`
skips every value that the environment currently supplies, so a credential
provided that way is not copied into the settings file when a plugin saves
an unrelated setting.
Unknown keys in a plugin's YAML file are ignored, so a settings file written by
a newer version of a plugin does not break an older one.

# Managing Plugins
Plugin packages extend MVT with additional
[forensic modules](index.md#custom-modules) and
[CLI commands](custom_commands.md). Because installed packages load
automatically, `mvt plugins` audits what is installed and checks whether
updates are available. The command lives on `mvt` only, although the packages
it lists extend `mvt-ios` and `mvt-android` too.
## List Installed Plugins
```bash
mvt plugins list
```
```

The origin records where each package was installed from: `pypi` for a package
installed from a package index, `git+<commit>` for a package installed directly
from a repository, and `local` for a package installed from a local folder or
archive rather than from an index, including an editable development install.
The last two columns show how many forensic modules the package contributes and
which CLI commands it adds.
A plugin whose modules cannot be imported is listed with `error` in the
`Modules` column rather than breaking the listing.
## Check for Updates
```bash
mvt plugins check-updates
```
```
Plugin updates available:
mvt-plugin-example 1.2.0 → 1.3.0
Upgrade with: pip install -U mvt-plugin-example
MVT does not install plugin updates. Run the command above when you decide to
upgrade.
```
Packages installed from a package index are compared against the latest release
published for them. A package which was never published, for example a plugin
distributed only within an organization, is skipped silently.
!!! note
Packages shown with the `pypi` origin are compared against
[PyPI](https://pypi.org), whichever index they were installed from. A
plugin installed from a private index under a name which also exists on
PyPI is therefore compared against the unrelated public package of that
name. Give plugins published to a private index a name which is not taken
on PyPI, and treat an unexpected update suggestion as a reason to check
where the package would come from.
!!! warning
MVT never installs or upgrades a plugin itself, it only prints the command
which does. Upgrading a plugin in the middle of an investigation changes
the modules producing the results, and a plugin runs as trusted code inside
the MVT process, so pulling in a new version is a decision for the analyst
to make deliberately and not a side effect of running a check.
## Automatic Update Checks
MVT also reports available plugin updates in the banner printed when a command
starts:
```
MVT - Mobile Verification Toolkit
https://mvt.re
Version: 2026.7.29
Plugin updates available:
mvt-plugin-example 1.2.0 → 1.3.0 (pip install -U mvt-plugin-example)
```
This check runs at most once every 12 hours. In between checks MVT prints the
findings of the latest check without contacting anything, so a plugin update
stays visible without a lookup on every command. The
`mvt plugins check-updates` command checks immediately, regardless of when the
last check happened.
The automatic check is skipped when the `--disable-update-check` option is
used, when `NETWORK_ACCESS_ALLOWED` is disabled in the MVT configuration, and
when no plugins are installed.
## Plugins Installed From a Repository
A plugin installed with `pip install "mvt-plugin-example @ git+<url>"` is
checked by asking the remote repository which commit the installed revision
points at now. MVT runs git and ssh in batch mode, so a repository which needs
credentials MVT does not already have fails the check instead of prompting for
them. The check is skipped silently when git is not available, when the
repository cannot be reached, and when access to it is denied.
How the plugin was installed decides what an update means:
- A plugin installed from a branch is reported as outdated when the branch has
moved past the installed commit.
- A plugin installed from a specific commit or a tag is pinned. It is never
reported as outdated, however far the branch it came from moves on.
Pinning a plugin to a commit or a tag is therefore the way to keep the modules
used across an investigation stable.

## Network Access
When checking URL indicators, MVT follows recognized shortened URLs with an
HTTP `HEAD` request. URL checks are deduplicated and run concurrently, with at
most 20 requests in progress at a time. Redirects within an individual URL
chain are still followed sequentially. The following environment variables
control these requests:
- `MVT_NETWORK_ACCESS_ALLOWED` enables or disables network requests. It defaults
to `true`. Set it to `false` to prevent MVT from attempting to resolve
shortened URLs.
- `MVT_NETWORK_TIMEOUT` sets the request timeout in seconds. It defaults to
`15`.
For example, to run IOC checks without resolving shortened URLs:
```bash
MVT_NETWORK_ACCESS_ALLOWED=false mvt-ios check-iocs \
--iocs ~/iocs/malware.stix2 /path/to/iphone/output/
```

Chat sessions produce `chat_first_message` and `chat_last_message` timeline events, and group chats additionally produce a `group_created` event. A chat session's last-message date can postdate its newest stored message when the most recent messages in the chat were deleted.
Recent WhatsApp versions key 1:1 chat sessions by an opaque LID identifier rather than the contact's phone number. The module resolves these using the `ZWAPHONENUMBERLIDPAIR` table from the *LID.sqlite* database in the same app group (or from *ChatStorage.sqlite* itself in versions that store it there), populating `partner_resolved_phone_number` on chat session records and using the phone number in timeline events. Each LID-phone number pair is also extracted as a record (`"record_type": "lid_phone_number_pair"`) and produces a `lid_pair_recorded` timeline event marking when WhatsApp learned the association.

Each timestamp stored on a contact record produces a timeline event: `disappearing_mode_set` (when the disappearing messages timer was last changed), `about_changed` (when the contact last changed their "about" text), `about_expiration` (when a timed "about" is scheduled to expire) and `contact_last_updated` (when the contact record was last updated).
This database is often missing from incremental backups. When it cannot be found, the module logs a warning and produces no results, in which case the disappearing messages state of chats cannot be determined from the backup.

# Check an iOS Sysdiagnose
`mvt-ios check-sysdiagnose` prepares an iOS sysdiagnose archive for analysis by
custom MVT modules. MVT does not include built-in sysdiagnose modules. The
command runs the modules of the installed
[plugin packages](../development/index.md#installed-module-packages) which
declare support for it. Install at least one such package first.
The command accepts either an extracted sysdiagnose directory or the original
gzip-compressed tar archive.
```bash
mvt-ios check-sysdiagnose --output ./results \
./sysdiagnose_2024.01.02_03-04-05+0200.tar.gz
```
Use `--hashes` to include hashes for analyzed files in `info.json`, and
`--list-modules` to display the eligible modules without running them.
## Writing a custom module
Extend `SysdiagnoseExtraction` from `mvt.plugin`, see
[Writing a module](../development/index.md#writing-a-module). The module reads
the archive the same way whether MVT was given a folder or a tar archive. It
declares the command in `supported_commands`. While writing one,
[load it from its file](../development/index.md#developing-modules-locally).
```python
from mvt.plugin import SysdiagnoseExtraction
class ExampleSysdiagnoseModule(SysdiagnoseExtraction):
supported_commands = (("ios", "check-sysdiagnose"),)
slug = "example_sysdiagnose"
def run(self):
paths = self._get_files_by_pattern("*/example.log")
if paths:
content = self._get_file_content(paths[0]).decode("utf-8", "replace")
self.results = [{"content": content}]
def check_indicators(self):
pass
def serialize(self, result):
return None
```
MVT extracts a tar archive first. It calls `from_sysdiagnose_folder()` on each
module before `run()`. `ips_files` lists the IPS crash reports.
`_get_files_by_pattern()` and `_get_file_content()` are internal helpers of the
base class. Use them to read the archive. Their names and signatures can change
between releases. See `src/mvt/ios/modules/sysdiagnose/base.py`.
