Binwalk uses the libmagic library, so this is consistent with the Unix file utility’s magical signatures.

Binwalk also consists of a custom signature report containing specialized signatures for documents typically found in firmware files such as compressed / archived files, firmware headers, Linux kernels, bootloaders, filesystems, etc.
Firmware Scanning
To list all Binwalk options – root@kali:~# binwalk -h To scan for embedded file types and systems in the firmware – root@kali:~# binwalk src_rxfw.07a To delete known file types from the firmware image – -e, –extract root@kali:~# binwalk -e src_rxfw.07a To scan the files again -M, –matryoshka root@kali:~# binwalk -Me src_rxfw.07a To extract from the firmware image a specific signature type root@kali:~# binwalk -D ‘png image:png’ src_rxfw.07a Entropical evaluation can help to discover fascinating factual parts in a firmware picture root@kali:~# binwalk -E src_rxfw.07a To diff the Hexdump values -W, –diff root@kali:~# binwalk -W src_rxfw.07a To disable and enable plugin -X, -Y. root@kali:~# binwalk -X src_rxfw.07a For a forensic analyst, Binwalk is a critical tool. In a forensic investigation it can be a precious device combined with other equipment.
