# binwalk

> Firmware Analysis Tool.
> More information: <https://github.com/ReFirmLabs/binwalk>.

- Scan a binary file:

`binwalk {{path/to/binary}}`

- Extract files from a binary, specifying the output directory:

`binwalk {{[-e|--extract]}} {{[-C|--directory]}} {{output_directory}} {{path/to/binary}}`

- Recursively extract files from a binary limiting the recursion depth to 2:

`binwalk {{[-e|--extract]}} {{[-M|--matryoshka]}} {{[-d|--depth]}} {{2}} {{path/to/binary}}`

- Extract files from a binary with the specified file signature:

`binwalk {{[-D|--dd]}} '{{png image:png}}' {{path/to/binary}}`

- Analyze the entropy of a binary, saving the plot with the same name as the binary and `.png` extension appended:

`binwalk {{[-E|--entropy]}} {{[-J|--save]}} {{path/to/binary}}`

- Combine entropy, signature and opcodes analysis in a single command:

`binwalk {{[-E|--entropy]}} {{[-B|--signature]}} {{[-A|--opcodes]}} {{path/to/binary}}`
