The Firmware Analysis and Comparison Tool (FACT)

codecov BCH compliance Codacy Badge Gitter chat Black Hat Arsenal

The Firmware Analysis and Comparison Tool (formerly known as Fraunhofer's Firmware Analysis Framework (FAF)) is intended to automate most of the firmware analysis process. It unpacks arbitrary firmware files and processes several analysis. Additionally, it can compare several images or single files.
Furthermore, Unpacking, analysis and compares are based on plug-ins guaranteeing maximal flexibility and expandability.
More details and some screenshots can be found on our project page.


FACT is designed as a multiprocess application, the more Cores and RAM, the better.

Minimal Recommended Software
4 Cores
16 Cores
Ubuntu (16.04 or 18.04)
Python 3.5 or above

It is possible to install FACT on any Linux distribution but the installer is limited to Ubuntu 16.04 and 18.04 at the moment.

❗️ Caution: FACT is not intended to be used as public internet service. The GUI is not a hardened WEB-application and it may take your server at risk!


The installation is generally wrapped in a single script. Some features can be selected specifically though. See for details.


You can start FACT by executing the start_all_installed_fact_components scripts. The script detects all installed components automatically.

$ ./start_all_installed_fact_components

Afterwards FACT can be accessed on http://localhost:5000 and https://localhost (nginx), respectively.

You can shutdown the system by pressing Ctrl + c or by sending a SIGTERM to the start_all_installed_faf_components script.

Advanced Usage

🔥 We're currently working to improving our documentation, including installation, getting started and alike. Follow progess on our wiki pages. ✌️


FACT provides a REST API. More information can be found here.

User Management

FACT provides an optional basic authentication, role and user management. More information can be found here.
