The Mobile Verification Toolkit (MVT) is an application that contains a collection of utilities to simplify and automate the process of collecting traces that are useful for detecting potential compromise of Android and iOS devices.

It was developed and released by the Amnesty International Security Lab in July 2021 as part of the Pegasus project along with a technical forensic methodology and other evidence.
Warning: MVT is a forensic investigation tool intended for technologists and investigators. Its use requires an understanding of the basics of forensic analysis and the use of command-line tools.
It is not intended for self-assessment by any end user. If you are concerned about the security of your device, seek help from experts.
