Used for analyzing, reverse engineering and extracting data from the firmware image.

• A. Binwalk
• B. Firmware Analysis
• C. Nmap
• D. Airmon-ng

Answer: (A)

Binwalk is designed to analyze firmware images by scanning for embedded filesystems and compressed data. It uses a signature database to identify components like SquashFS, CramFS, and common archives (gzip, bzip2, xz, etc.), and can automatically extract them. This makes it ideal for reverse engineering firmware because you can reveal the exact layout, pull out the kernel, root filesystem, binaries, and configuration data for inspection and modification. In practice, you’d scan the firmware image and then use extraction to obtain the embedded content for deeper analysis. By comparison, firmware analysis is a broad activity rather than a single tool; Nmap is a network scanner for discovering hosts and services on a network; Airmon-ng is for enabling monitor mode on wireless adapters and is not used for parsing firmware binaries.
