Donncha Ó Cearbhaill b3585e76ad Add a --verbose option to the mvt, mvt-ios and mvt-android commands
Verbosity was an option of each module-running command, so
"mvt-ios --verbose check-backup" was a usage error, a plugin command had to
define a flag of its own, and there was no way to get debug output from mvt at
all.

The option now sits on the three commands themselves and sets the level of
MVT's console handler for the run, through set_verbose_logging(), before any
command runs. Plugin commands registered on any of the three CLIs get the
option for free and need none of their own.

The per-command --verbose of the check-* commands is kept for backward
compatibility. It only ever raises the level, so the CLI's choice is never
undone by a command's default, and its help text says it is kept for
compatibility. It is to be removed in a later release.

Donncha Ó Cearbhaill 1e45ead1a5 Find the console log handler by type when changing verbosity
set_verbose_logging() adjusted the first handler on the "mvt" logger,
whichever handler that happened to be. Anything else attaching a
handler to that logger - an embedding application, a plugin, a test
harness - had it mistaken for the console and raised or lowered behind
its back, and the same slot can hold the file handler a command
attaches to its output folder, whose level a --verbose flag should
never decide: command.log records the whole run either way.

Walk the handlers instead and adjust only MVT's own console handler,
found by its MVTLogHandler type. Every other handler on the logger is
left alone. Behaviour is otherwise unchanged.

Donncha Ó Cearbhaill 348b47db35 Add a plugins command to list installed plugins and check updates
Add a "plugins" command to the platform-neutral mvt command. "plugins
list" shows every installed plugin package with its version, where it was
installed from, how many forensic modules it contributes and which
commands it adds. "plugins check-updates" checks for updates immediately,
without waiting for the automatic check, and prints the command which
upgrades a plugin instead of installing anything.

It lives on mvt only. The packages it lists extend mvt-ios and mvt-android
too, but auditing them is not the job of a command which analyses one
platform, and the two platform CLIs should not carry commands which are
not about an acquisition.

The command is registered as a built-in, before any external command, so
that an installed package cannot replace this audit surface.

Donncha Ó Cearbhaill b768d5b86c Add plugin update checking
Report available updates to the installed MVT plugin packages in the
startup banner, for plugins installed from a package index and for
plugins installed directly from a repository. Repository installs pinned
to a commit or a tag are never reported as outdated.

MVT only prints the command which upgrades a plugin. Installing the
update stays a deliberate choice of the analyst. The check runs at most
once every twelve hours, and in between prints the findings of the
latest check which still apply to what is installed.

Nothing about the check can interrupt a running command: the parts of
the suggested command come from package metadata and are quoted for the
shell, the repository query refuses to prompt for credentials and never
passes metadata as a git option, and a corrupt or stale cache is
discarded rather than trusted.

Donncha Ó Cearbhaill c4215ec163 Point the README and the command docs at plugin packages
Loading a command by path is for local development; a package is how a
command is distributed. The README's summary of what extends MVT now
names plugin packages and nothing else, and the section on loading a
command file says what it is for: keeping a command being written
loadable without reinstalling its package after every change.

Donncha Ó Cearbhaill 36d1b27c4c Move shell completion to the mvt command and generate one script for every MVT command
Setting up shell completion had nothing to do with the acquisition of one
platform, yet it was a command of mvt-ios and mvt-android, each
generating the script of the program it ran under only. Completion now
leaves the platform CLIs for mvt, which emits one script covering mvt,
mvt-ios and mvt-android, installed as a single file loaded when the shell
starts. Click names the completion function of each program after the
program, so the three scripts concatenate without colliding, and fish
takes the file in conf.d rather than one named after a single command.

With one script there is nothing left for the platform commands to
generate, so their completion command goes, and with it the banner
suppression which was keyed on the command name: mvt-ios and mvt-android
now print the banner for every command they have.

The long help line says which commands the completion covers, so a
short_help keeps "mvt --help" from truncating it.

Donncha Ó Cearbhaill c95e6659c6 Add a platform-neutral mvt command
Several MVT commands have nothing to do with the acquisition of one
platform, yet they were reachable only through mvt-ios and mvt-android.
Asking which version is installed or downloading the public indicators
meant picking one of the two platform commands arbitrarily, and each of
those tasks had to be written, documented and maintained twice.

Add a third console script, mvt, hosting the commands which belong to no
platform: version and download-iocs for now, with completion following
in a later commit.

Commands installed in the new mvt.cli_plugins entry-point group are
registered on mvt, and on mvt only, so that a command package chooses
the CLI each of its commands is added to: mvt.ios.cli_plugins for
mvt-ios, mvt.android.cli_plugins for mvt-android and mvt.cli_plugins for
mvt. A command wanted on both platform CLIs is registered in both
platform groups; no group adds a command to every CLI. The
MVT_CUSTOM_COMMANDS variable loads command files and folders into mvt
the way the platform variables already do for mvt-ios and mvt-android.

Run on its own, mvt prints the banner and its help instead of a usage
error. The help text reminds that the forensic analysis of an
acquisition runs through mvt-ios and mvt-android, so that the command
which knows nothing about acquisitions says where they are analysed.

version and download-iocs stay on mvt-ios and mvt-android for now, so
that no documented invocation stops working. They are to be dropped from
the platform CLIs in a later release, once mvt has been available long
enough for the change to be announced.

Unlike mvt-ios and mvt-android, which point at their subpackages, the
console script points at mvt.cli:main and the mvt package re-exports
nothing of it. Importing mvt has to stay cheap and free of side effects:
it is the package plugins import from, and pulling in Click, the CLI and
everything the commands import merely because something imported mvt
would work against that.

While here, give the version command of both platform CLIs the context
settings every other command already has, so that "mvt-ios version -h"
prints its help instead of failing on an unknown option.

Donncha Ó Cearbhaill f8456059db Register installed CLI plugins at program start
register_cli_plugins() ran while mvt.ios and mvt.android were being
imported, so importing any part of MVT executed the entry points of every
installed command package. That made plugin loading depend on import
order: a plugin importing from MVT while MVT was still initializing got an
ImportError and was quietly demoted to a broken command, and the same
plugin worked when MVT happened to be imported first.

Move the call into a main() function in each CLI module and point the
console scripts at it, so registration happens once when the program
starts and importing MVT no longer runs third-party code. For packagers:
mvt.ios:cli and mvt.android:cli stay importable, but a wrapper invoking
cli() directly no longer registers the installed plugin commands and
should call main() instead.

Donncha Ó Cearbhaill efbab29f94 Skip modules with unavailable dependencies instead of aborting the run
A module declaring a dependency its command does not provide made
_ordered_modules() give up on the whole run, so a single wrong declaration
in a module scoped to several commands turned a forensic analysis into
zero executed modules with one warning to explain it.

Drop only the modules that cannot run: the one with the unavailable
dependency, and anything depending on it. Each gets its own warning naming
the module missing a dependency and the dependency it is missing, and the
remaining modules run in the same stable topological order as before. A
cycle in the dependency graph is still a programming error and still stops
the run.

Donncha Ó Cearbhaill ecc22f54b7 Derive the data folder of a plugin from its settings class
A plugin with a settings class already names itself in `plugin_name`;
passing the name again to plugin_data_folder() repeats it and can drift.
Add a `data_folder()` class method on MVTPluginSettings which returns
plugin_data_folder() for the class's validated plugin name (works on the
class and on an instance); plugin_data_folder(name) stays as the function
underneath for plugins without a settings class.

Donncha Ó Cearbhaill 90fc0ae351 Add per-plugin data folders
Plugins had no sanctioned place to keep the data they persist, so the
plugin configuration documentation suggested a CACHE_FOLDER setting
defaulting to ~/.cache/example-plugin. That is a Linux convention which
is wrong on macOS, nothing expands or creates it, and it turns a path
into a setting a user can be asked to configure.

Add plugin_data_folder(), which returns the folder a plugin should use
for caches, downloaded artifacts, synchronization state or anything
else it writes to disk, and creates it if it is missing. The plugin
name is validated before anything is created, so a name holding a path
separator raises an error and leaves no folder behind, and calling the
function again returns the same folder with its contents untouched.

The folder sits under plugin-data rather than under the plugins folder
which holds the settings files. On macOS the configuration folder and
the data folder are the same directory, so reusing the plugins name
would leave each plugin's data folder in among the settings files.

Both the plugin-data folder and the folder of each plugin are created
with 0700 permissions. MVT is a forensic tool, and what a plugin keeps
there, such as API responses or sample metadata, is private by default.
The path is resolved on every call, as the configuration folder already
is, so it follows the current environment rather than whatever it was
when MVT was imported.

The documentation now points plugins at the helper, and the example
settings class carries a plain integer setting in place of its cache
folder.

Donncha Ó Cearbhaill dab82e38d0 Add namespaced plugin configuration support
Plugin packages need somewhere to keep their own settings, but MVT
rewrites its config.yaml with only the fields it knows about, so any
foreign section is dropped. Add MVTPluginSettings, a pydantic-settings
base class that gives each plugin its own file under the MVT config
folder and its own MVT_PLUGIN_<NAME>_ environment variable namespace.

Settings resolve from constructor arguments, then the environment, then
the plugin file, then the field defaults. Saving skips the values the
environment currently supplies, so credentials passed as environment
variables are not copied to disk, and writes through a private temporary
file so a settings file is never partially written or briefly readable
by other users.

## 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:

class ExampleCustomModule(MVTModule):
supported_commands = (("ios", "check-backup"), ("ios", "check-fs"))
slug = "example_custom_module"
def run(self):

`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.
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
from mvt.ios.modules.backup.manifest import Manifest
class DependentCustomModule(MVTModule):
@@ -169,85 +124,6 @@ class DependentCustomModule(MVTModule):
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.

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

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`.
The base class provides `from_sysdiagnose_folder()` and
`from_sysdiagnose_tar()` setup hooks, as well as protected file lookup, file
reading, and timezone extraction helpers. IPS crash-report metadata is exposed
on `ips_files`.
