SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires subfinder, chaosapi, nuclei, katana, waybackurls, gau, ffuf, linkfinder, secretfinder, and includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill provides a robust, step-by-step web2 reconnaissance pipeline to identify potential vulnerabilities in a target website, including asset discovery, subdomain enumeration, live host detection, URL crawling, directory fuzzing, and JavaScript analysis.

Core Features & Use Cases

  • Asset Discovery: Enumerates subdomains, identifies live hosts, and crawls URLs for a comprehensive asset inventory.
  • Subdomain Enumeration: Utilizes subfinder, Chaos API, and assetfinder to uncover potential subdomains.
  • Live Host Detection: Performs DNS resolution and HTTP checks to identify active hosts.
  • URL Crawling: Utilizes katana, waybackurls, and gau to crawl and discover URLs.
  • Directory Fuzzing: Uses ffuf to fuzz directories and find hidden resources.
  • JavaScript Analysis: Employ LinkFinder and SecretFinder to analyze JavaScript files for hidden endpoints and secrets.
  • Use Case: When beginning reconnaissance on a web2 target, use this Skill to identify potential entry points for further analysis.

Quick Start

FAQPage Schema
How do I automate web reconnaissance for subdomain enumeration and live host detection?

Automate web reconnaissance by running a pipeline that uses subfinder and Chaos API for subdomain enumeration, then performs DNS resolution and HTTP checks for live host detection on the target website.

What is the best way to crawl URLs and fuzz directories during vulnerability assessment?

The best way to crawl URLs and fuzz directories is using katana, waybackurls, and gau for URL discovery, paired with ffuf for directory fuzzing to uncover hidden resources on the target.

How do I analyze JavaScript files for hidden endpoints and secrets?

Analyze JavaScript files for hidden endpoints and secrets by employing LinkFinder and SecretFinder to parse and extract sensitive data from JS assets discovered during the URL crawling phase.

Do I need external tools and APIs to perform comprehensive web2 reconnaissance?

Yes, comprehensive web2 reconnaissance requires external tools and services like subfinder, Chaos API, nuclei, katana, waybackurls, gau, ffuf, LinkFinder, and SecretFinder to execute the full pipeline.

Can I use this pipeline for vulnerability assessment on a specific target website?

Yes, you can use this pipeline for vulnerability assessment by initiating a full reconnaissance on a target website to identify potential entry points, assets, and vulnerabilities for further analysis.

What are the limitations of using automated URL crawling for asset discovery?

Automated URL crawling using tools like waybackurls and gau relies on historical data and passive sources, meaning it may miss newly created endpoints, dynamically generated links, or resources blocked from crawling.
