Analyzing embedded files and executable code with Firmware Images – Binwalk
Binwalk is a device for looking a given binary image for embedded documents and executable code. Specifically, it’s far designed for figuring out files and code embedded inner of firmware images.Binwalk uses the libmagic library, so it is compatible with magic signatures created for the Unix file utility.

Binwalk additionally consists of a custom magic signature report which contains progressed signatures for documents which are typically found in firmware photos including compressed/archived files, firmware headers, Linux kernels, bootloaders, filesystems, and so forth.
Scanning Firmware
To list all the options with Binwalk. root@kali:~# binwalk -h
To scan the firmware for embedded file types and systems.
root@kali:~# binwalk src_rxfw.07a
To extract known file types from the firmware image -e, –extract
root@kali:~# binwalk -e src_rxfw.07a
To scan the files Recursively -M, –matryoshka
root@kali:~# binwalk -Me src_rxfw.07a
