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
