What tools are required for this Claude Code skill?

The skill utilizes standard binutils like strings, hexdump, xxd, and file. For advanced firmware extraction, binwalk should be installed via pip or cargo.

Can I use this for security auditing?

Absolutely. It is specifically designed to find hardcoded secrets, analyze file entropy for encryption detection, and inspect ELF/MZ headers.

How does it handle different string encodings?

The skill includes patterns for extracting 7-bit ASCII, as well as 16-bit and 32-bit little-endian and big-endian strings (UTF-16/UTF-32).

Can it extract files from a firmware blob?

Yes, it provides automated commands for binwalk to identify and recursively extract embedded files, filesystems, and compressed data.

Security & Testing

Analyzes binary files and firmware to extract strings, identify file signatures, and explore raw data using industry-standard tools.

About

This skill empowers Claude to perform deep inspections of binary files, firmware images, and unknown data blobs by leveraging specialized utilities like strings, binwalk, and hexdump. It is designed for security researchers and developers who need to identify embedded files, extract hardcoded credentials, and visualize file entropy to detect compressed or encrypted regions. By providing a structured workflow for reverse engineering, it streamlines the process of discovering library versions, debug symbols, and hidden signatures within compiled code.

Key Features

Extract printable text and UTF-16/32 strings with specific offset tracking
Perform raw hex and ASCII dumps with precise byte-range targeting
Analyze file entropy to locate compressed, encrypted, or obfuscated data
Detect file types and magic byte signatures for unknown or corrupted data
3 GitHub stars
Identify and recursively extract embedded files from firmware using binwalk

Use Cases

Auditing compiled binaries for debug symbols and sensitive error messages
Investigating suspicious binary files for hidden payloads or embedded archives
Reverse engineering IoT firmware to discover hardcoded credentials and API keys
