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}}
