The Firmware Mod Kit allows for easy deconstruction and reconstruction of firmware images for various embedded devices. While it primarily targets Linux based routers, it should be compatible with most firmware that makes use of common firmware formats and file systems such as TRX/uImage and SquashFS/CramFS.
Only use this tool against systems you own or are explicitly authorized to test — see the disclaimer.
Getting started
Install on Kali Linux with `sudo apt install firmware-mod-kit`. See the official Kali tool page and upstream homepage linked above for full usage and configuration details.
