Add the possibility of having user-defined modules (not only plugins for existing modules)


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


Binwalk follows the standard Python installation procedure:

$ sudo python install

If you're running Python 2.x, you'll also want to install the Python lzma module:

$ sudo apt-get install python-lzma

For instructions on installing optional dependencies, see


Basic usage is simple:

$ binwalk firmware.bin
