### 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.

# Backup with libimobiledevice
|
||||
|
||||
If you have correctly [installed libimobiledevice](../install.md) you can easily generate an iTunes backup using the `idevicebackup2` tool included in the suite. First, you might want to ensure that backup encryption is enabled (**note: encrypted backup contain more data than unencrypted backups**):
|
||||
|
||||
```bash
|
||||
idevicebackup2 -i encryption on
|
||||
```
|
||||
|
||||
Note that if a backup password was previously set on this device, you might need to use the same or change it. You can try changing password using `idevicebackup2 -i changepw`, or by turning off encryption (`idevicebackup2 -i encryption off`) and turning it back on again.
|
||||
|
||||
If you are not able to recover or change the password, you should try to disable encryption and obtain an unencrypted backup.
|
||||
|
||||
If all else fails, as a *last resort* you can try resetting the password by [resetting all the settings through the iPhone's Settings app](https://support.apple.com/en-us/HT205220), via `Settings » General » Reset » Reset All Settings`. Note that resetting the settings through the iPhone's Settings app will wipe some of the files that contain useful forensic traces, so try the options explained above first.
|
||||
|
||||
Once ready, you can proceed performing the backup:
|
||||
|
||||
```bash
|
||||
idevicebackup2 backup --full /path/to/backup/

# Backup with pymobiledevice3
|
||||
|
||||
After [installing pymobiledevice3](../install.md) and pairing your device, you can generate an iTunes-compatible backup using its `backup2` commands.
|
||||
|
||||
## Enable backup encryption
|
||||
|
||||
We recommend encrypted backups because they contain more data than unencrypted backups. If encryption is not already enabled, enable it with:
|
||||
|
||||
```bash
|
||||
pymobiledevice3 backup2 encryption on 'YOUR_BACKUP_PASSWORD'
|
||||
```
|
||||
|
||||
Replace `YOUR_BACKUP_PASSWORD` with a strong password and keep it safe: you will need it to decrypt the backup for analysis. Passwords supplied on the command line may be saved in shell history or visible to other processes.
|
||||
|
||||
If a backup password was previously set, use that password. To change a known password:
|
||||
|
||||
```bash
|
||||
pymobiledevice3 backup2 change-password 'CURRENT_PASSWORD' 'NEW_PASSWORD'
|
||||
```
|
||||
|
||||
You can also disable encryption with `pymobiledevice3 backup2 encryption off 'CURRENT_PASSWORD'` and then enable it again. Disabling encryption requires the current password; it is not a way to bypass an unknown password.
|
||||
|
||||
!!! warning
|
||||
If you cannot recover the password, resetting it through [Reset All Settings in the iPhone's Settings app](https://support.apple.com/en-us/HT205220) should be a last resort. Resetting settings can remove files containing useful forensic traces.
|
||||
|
||||
## Create a backup
|
||||
|
||||
Choose a new destination directory to avoid overwriting an earlier acquisition:
|
||||
|
||||
```bash
|
||||
mkdir -p /path/to/backup/
|
||||
pymobiledevice3 backup2 backup --full /path/to/backup/
|
||||
```
|
||||
|
||||
The backup is saved in a subdirectory named after the device's UDID, such as `/path/to/backup/udid/`. Follow [Check a Backup with mvt-ios](check.md) to decrypt and analyze that directory.
|
||||
|
||||

Before proceeding with doing any acquisition of iOS devices we recommend installing [libimobiledevice](https://libimobiledevice.org/) utilities. These utilities will become useful when extracting crash logs and generating iTunes backups. Because the utilities and its libraries are subject to frequent changes in response to new versions of iOS, you might want to consider compiling libimobiledevice utilities from sources. Otherwise, if available, you can try installing packages available in your distribution:
|
||||
Before acquiring data from an iOS device, we recommend installing [pymobiledevice3](https://github.com/doronz88/pymobiledevice3). It provides command-line tools for generating iTunes-compatible backups and extracting crash logs.
|
||||
|
||||
## Installation
|
||||
|
||||
Install `pipx` following the [MVT installation instructions](../install.md), then run:
|
||||
|
||||
```bash
|
||||
sudo apt install libimobiledevice-utils
|
||||
pipx install pymobiledevice3
|
||||
```
|
||||
|
||||
On Mac, you can try installing it from brew:
|
||||
To update an existing installation:
|
||||
|
||||
```bash
|
||||
brew install --HEAD libimobiledevice
|
||||
pipx upgrade pymobiledevice3
|
||||
```
|
||||
|
||||
If you have a reasonably recent version of libimobiledevice in your package manager, it might work straight out of the box. Try connecting your iOS device to your computer via USB and run:
|
||||
On Linux, you also need `usbmuxd` to communicate with devices over USB. On Debian and Ubuntu, install it with:
|
||||
|
||||
```bash
|
||||
ideviceinfo
|
||||
sudo apt install usbmuxd
|
||||
```
|
||||
|
||||
If you encounter unexpected issues, uninstall the packages and try compiling libimobiledevcice from sources.
|
||||
macOS includes the required USB device service. For other platforms and additional requirements, see the [pymobiledevice3 installation documentation](https://doronz88.github.io/pymobiledevice3/installation/).
|
||||
|
||||
## Compile libimobiledevice from sources
|
||||
## Verify connectivity
|
||||
|
||||
!!! warning
|
||||
The following instructions are a best effort. The installation from source requires several steps, and it is likely some have been forgotten here and that won't work for you. You will likely need to fiddle around a bit before getting this right.
|
||||
|
||||
Make sure you have uninstalled all the libimobiledevice tools from your package manage:
|
||||
Connect the iOS device to your computer with a USB cable and unlock it. Accept the **Trust This Computer** prompt and enter the device passcode if requested. Then run:
|
||||
|
||||
```bash
|
||||
sudo apt remove --purge libimobiledevice-utils libimobiledevice-dev libimobiledevice6 libplist-dev libplist3 libusbmuxd-dev libusbmuxd-tools libusbmuxd4 libusbmuxd6 usbmuxd
|
||||
pymobiledevice3 usbmux list
|
||||
pymobiledevice3 lockdown info
|
||||
```
|
||||
|
||||
Firstly you need to install [libplist](https://github.com/libimobiledevice/libplist). Then you can install [libusbmuxd](https://github.com/libimobiledevice/libusbmuxd).
|
||||
|
||||
Now you should be able to to download and install the actual suite of tools at [https://github.com/libimobiledevice/libimobiledevice](https://github.com/libimobiledevice/libimobiledevice).
|
||||
|
||||
You can now also build and install [usbmuxd](https://github.com/libimobiledevice/usbmuxd).
|
||||
|
||||
## Making sure everything works fine.
|
||||
|
||||
Once the idevice tools are available you can check if everything works fine by connecting your iOS device and running:
|
||||
These commands should list the connected device and display its details. If pairing is needed, run:
|
||||
|
||||
```bash
|
||||
ideviceinfo
|
||||
pymobiledevice3 lockdown pair
|
||||
```
|
||||
|
||||
This should show many details on the connected iOS device. If you are connecting the device to your laptop for the first time, it will require to unlock and enter the PIN code on the mobile device. If it complains that no device is connected and the mobile device is indeed plugged in through the USB cable, you might need to do this first, although typically the pairing is automatically done when connecting the device:

# Output schemas
|
||||
|
||||
MVT validates its JSON output with versioned Pydantic models. The schema version
|
||||
used for a run is recorded as `output_schema_version` in `info.json`.
|
||||
|
||||
MVT preserves the established on-disk format: most module files contain an array
|
||||
of result objects, while modules whose results are naturally grouped contain an
|
||||
object keyed by source or namespace. Detection files and `alerts.json` contain
|
||||
arrays of alert objects. Timestamps remain strings because their timezone and
|
||||
precision depend on the source artifact.
|
||||
|
||||
## Exporting JSON Schema
|
||||
|
||||
Both platform commands can print a versioned JSON Schema bundle:
|
||||
|
||||
```bash
|
||||
mvt-ios schemas
|
||||
mvt-android schemas
|
||||
```
|
||||
|
||||
Use `--output` to write one Draft 2020-12 JSON Schema file for each output:
|
||||
|
||||
```bash
|
||||
mvt-ios schemas --output ./mvt-ios-schemas
|
||||
mvt-android schemas --output ./mvt-android-schemas
|
||||
```
|
||||
|
||||
## Python API
|
||||
|
||||
Models and schema discovery functions are available from `mvt.schemas`:
|
||||
|
||||
```python
|
||||
from mvt.schemas import get_output_model
|
||||
|
||||
SafariHistoryOutput = get_output_model("safari_history", platform="ios")
|
||||
validated = SafariHistoryOutput.model_validate(records)
|
||||
json_schema = SafariHistoryOutput.model_json_schema()
|
||||
```
|
||||
|
||||
Common outputs have dedicated field-level models. Built-in module outputs have a
|
||||
declared root shape, and modules with an established dedicated record model expose
|
||||
its complete field schema.
|
||||
|
||||
## Custom modules
|
||||
|
||||
Custom modules can publish a precise contract by assigning a Pydantic root model
|
||||
to `output_model`:
|
||||
|
||||
```python
|
||||
from pydantic import BaseModel, RootModel
|
||||
|
||||
from mvt.common.module import MVTModule
|
||||
|
||||
|
||||
class ExampleRecord(BaseModel):
|
||||
message: str
|
||||
timestamp: str | None = None
|
||||
|
||||
|
||||
class ExampleOutput(RootModel[list[ExampleRecord]]):
|
||||
pass
|
||||
|
||||
|
||||
class ExampleModule(MVTModule):
|
||||
output_model = ExampleOutput
|
||||
```
|
||||
|
||||
For compatibility, a custom module without `output_model` can still write an
|
||||
array or object containing JSON values. MVT logs a warning when it uses this
|
||||
generic contract. A future major release may require custom modules to declare
|
||||
their output models.
|
||||
|
||||
## Compatibility policy
|
||||
|
||||
Within one output schema major version, required fields are not removed and field
|
||||
types are not narrowed. New optional fields may be added. A breaking output
|
||||
change requires a new schema major version and a migration note.
