* 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. * Reduce indent for MVT CLI header * 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. * 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.

Mobile Verification Toolkit
Important
We recently merged the "v3" branch. This introduced breaking changes. If you relied on mvt output in other scripts They might have broken. More details: https://github.com/mvt-project/mvt/issues/757
Mobile Verification Toolkit (MVT) is a collection of utilities to simplify and automate the process of gathering forensic traces helpful to identify a potential compromise of Android and iOS devices.
It has been developed and released by the Amnesty International Security Lab in July 2021 in the context of the Pegasus Project along with a technical forensic methodology. It continues to be maintained by Amnesty International and other contributors.
Note
MVT is a forensic research tool intended for technologists and investigators. It requires understanding digital forensics and using command-line tools. This is not intended for end-user self-assessment. If you are concerned with the security of your device please seek reputable expert assistance.
Indicators of Compromise
MVT supports using public indicators of compromise (IOCs) to scan mobile devices for potential traces of targeting or infection by known spyware campaigns. This includes IOCs published by Amnesty International and other research groups.
Warning
Public indicators of compromise are insufficient to determine that a device is "clean", and not targeted with a particular spyware tool. Reliance on public indicators alone can miss recent forensic traces and give a false sense of security.
Reliable and comprehensive digital forensic support and triage requires access to non-public indicators, research and threat intelligence.
Such support is available to civil society through Amnesty International's Security Lab or through our forensic partnership with Access Now’s Digital Security Helpline.
More information about using indicators of compromise with MVT is available in the documentation.
Installation
MVT can be installed from sources or from PyPI (you will need some dependencies, check the documentation):
pip3 install mvt
You can also install MVT from PyPI with uv. First, install uv:
curl -LsSf https://astral.sh/uv/install.sh | sh
Then install MVT as a command-line tool:
uv tool install mvt
For alternative installation options and known issues, please refer to the documentation as well as GitHub Issues.
Usage
MVT provides three commands: mvt-ios and mvt-android analyse acquisitions from devices of that platform, and mvt hosts what belongs to neither: version, completion 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!
Shell completion
MVT can generate a shell completion script for Bash, Zsh, and Fish which covers mvt, mvt-ios and mvt-android:
mvt completion
The command prints setup instructions by default. To generate the completion script directly, pass the shell name:
mvt completion bash
MVT only writes completion files or shell configuration when --install is passed. See the command completion documentation 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 for
writing and installing them, and the
custom CLI command documentation
for the entry points a package registers commands in.
License
The purpose of MVT is to facilitate the consensual forensic analysis of devices of those who might be targets of sophisticated mobile spyware attacks, especially members of civil society and marginalized communities. We do not want MVT to enable privacy violations of non-consenting individuals. In order to achieve this, MVT is released under its own license. Read more here.
