Summary

Chunsou is a Python 3 multi-threaded web fingerprinting tool designed for security testers and network security professionals. It aims to streamline early-stage asset identification, risk assessment, and enterprise internet asset investigation by providing rapid and efficient web asset profiling.

How It Works

The tool employs multi-threaded scanning to identify web assets, leveraging a database of over 10,000 fingerprint rules. These rules match against website keywords, titles, headers, and icon hashes. Chunsou also integrates auxiliary functions like subdomain enumeration (via OneForAll) and asset collection through Fofa and Hunter APIs, enhancing its utility for comprehensive reconnaissance.

Quick Start & Requirements

• Installation: pip3 install -r requirements.txt
• Prerequisites: Python 3. Requires API keys for Fofa and Hunter, configured in /modules/config/config.ini. AI features require API keys for providers like DeepSeek or OpenAI (GPT).
• Usage: Core commands include python3 chunsou.py -u <url> for single URL scanning, python3 chunsou.py -f <urls.txt> for batch scanning, python3 chunsou.py -du <domain> for subdomain blasting, and API calls like python3 chunsou.py -fo domain="example.com".
