|
||||
|
||||
```bash
|
||||
curl -LsSf https://astral.sh/uv/install.sh | sh
|
||||
```
|
||||

```bash
|
||||
uv tool install mvt
|
||||
```
|
||||
|
||||
For alternative installation options and known issues, please refer to the [documentation](https://docs.mvt.re/en/latest/install/) as well as [GitHub Issues](https://github.com/mvt-project/mvt/issues).
|
||||
|
||||
|
||||
## Usage
|
||||
|
||||
MVT provides two commands `mvt-ios` and `mvt-android`. [Check out the documentation to learn how to use them!](https://docs.mvt.re/)
|
||||
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

||||

# 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
|
||||
|
||||
AndroidQF records APK file hashes in `packages.json`. MVT can optionally look up non-system APK hashes on VirusTotal while checking an AndroidQF acquisition:
|
||||
|
||||
```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.

||||
|
||||
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

from a repository, and `local` for a package installed from a local folder or

The last two columns show how many forensic modules the package contributes and

## 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.

On the Linux host, install and start [usbmuxd](https://github.com/libimobiledevice/usbmuxd), then connect and unlock the iOS device. The daemon exposes the device through the `/var/run/usbmuxd` socket.

|

|

## 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 \
|
||||

This JSON file is created by mvt-ios' `WhatsApp` module. The module extracts a list of WhatsApp messages from the SQLite database located at *private/var/mobile/Containers/Shared/AppGroup/\*/ChatStorage.sqlite*, along with one record per chat session (marked with `"record_type": "chat_session"`) containing the first and last interaction dates of each conversation. 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.
|
||||
|

If indicators are provided through the command-line, they are checked against the extracted HTTP links. Any matches are stored in *whatsapp_detected.json*.

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).

# 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`.

Performance note

----------------
|

Log files can be large and are shared by every module in this package.
|
||||
To avoid re-reading and re-parsing the same files N times (once per
|
||||
module), the command layer should call :meth:`load_all_events` exactly
|
||||
once and then assign the returned dict to the ``il_events_by_type``
|
||||
attribute of every module instance **before** calling ``run_module``.
|
||||
|
||||
When ``il_events_by_type`` is populated:
|
||||
* :meth:`collect_txt` becomes a no-op (no disk I/O).
|
||||
* :meth:`parse_collected_txt` iterates the in-memory list for the
|
||||
requested event type instead of re-parsing raw text.
|
||||
|
||||
Modules that are used standalone (e.g. in tests) still work as before
|
||||
because ``il_events_by_type`` defaults to ``None``, which preserves the
|
||||
original file-loading code path.
