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 --extract --directory output_directory path/to/binary

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

binwalk --extract --matryoshka --depth 2 path/to/binary

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

binwalk --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 --entropy --save path/to/binary

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

binwalk --entropy --signature --opcodes path/to/binary
