Binwalk is a fast, easy to use tool for analyzing, reverse engineering, and extracting firmware images.

Installation and Usage

More information on Wiki

Quick start


Binwalk follows the standard Python installation procedure:

$ sudo python install

If you're running Python 2.x, installing the optional Python lzma module is strongly recommended (but not required):

$ sudo apt-get install python-lzma

For instructions on installing other optional dependencies, see installation guide.


Basic usage is simple:

$ binwalk firmware.bin
