Install: brew install binwalk
About:
Binwalk is a firmware analysis tool that scans binary images to identify and extract embedded filesystems, compressed archives, and executable code. It supports signature-based scanning and automated extraction of embedded components, making it essential for reverse engineering proprietary firmware. The tool helps security researchers analyze device firmware without needing vendor-specific tools.
Key Features:
  • Signature-based scanning for file formats and executable code
  • Automatic extraction of embedded filesystems and archives
  • Entropy analysis for visualizing encrypted or compressed data
  • Plugin architecture for custom signatures and analysis modules
  • Recursive extraction capabilities for nested data structures
Use Cases:
  • Security researchers analyzing firmware for vulnerabilities or backdoors
  • Embedded systems engineers extracting proprietary device filesystems
  • Malware analysts dissecting malicious binaries for embedded payloads
Alternatives:
  • foremost – Foremost is a simpler file carver that lacks binwalk's advanced entropy analysis and signature database
  • hexdump – Hexdump provides raw binary viewing but no automated analysis or extraction capabilities
