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).

|

## 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.

## 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.
|
||||
Module-running `check-*` commands can load custom modules from Python files that
|
||||
are not installed as part of MVT. Load one file with:

|
||||
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.
|
||||
```bash
|
||||
mvt-ios check-backup --load-module ./example_module.py --output ./out ./backup
|
||||
```
|
||||
|
||||
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:
|
||||
You can also load a folder. MVT loads non-hidden top-level `*.py` files in
|
||||
sorted order and skips `__init__.py`:
|
||||
|
||||
```bash
|
||||
mvt-ios check-fs --load-module ./custom_modules ./filesystem-dump
|
||||
```
|
||||
|
||||
Set `MVT_CUSTOM_MODULES` to load a folder for every module-running command. This
|
||||
folder is loaded before any `--load-module` path:
|
||||
|
||||
```bash
|
||||
MVT_CUSTOM_MODULES=./custom_modules mvt-android check-bugreport ./bugreport.zip
|
||||
```
|
||||
|
||||
Custom modules are normal `MVTModule` subclasses:
|
||||
|
||||
```python
|
||||
from mvt.common.module import MVTModule
|
||||
|
||||
|
||||
class ExampleCustomModule(MVTModule):

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.
|
||||
Custom modules can depend on existing MVT module classes. Dependencies are
|
||||
resolved with the same ordering logic as built-in modules, and custom modules
|
||||
are appended after built-ins before ordering:
|
||||
|
||||
```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
|
||||
from mvt.common.module import MVTModule
|
||||

```
|
||||
|
||||
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

||||
|
||||
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.

## 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.

`SysdiagnoseInfo` module extracts details about the device and the archive

declare support for the command. Without any such module the command still

records the device details, and warns that no forensic sysdiagnose modules

have been loaded so that the run cannot pass for a clean analysis.
|

`mvt-ios check-sysdiagnose` prepares an iOS sysdiagnose archive for analysis by

custom MVT modules. MVT does not include built-in sysdiagnose modules. You must

the archive the same way whether MVT was given a folder or a tar archive. It

Extend `SysdiagnoseExtraction` to access the archive contents consistently for

both directory and tar inputs. Each module must declare the command explicitly
