web-application-recon-and-enumeration

web-application-recon-and-enumeration is a skill for Claude Code from akashrpatil/awesome-offensive-security-skills. It costs 79 tokens per session (2,535 once invoked), scanned A, original, Apache-2.0.

A web security assessment workflow for mapping a website or web application before testing it for vulnerabilities. It finds subdomains, hidden paths, open ports, technologies, and other exposed content.

In plain words
What is it for?
Use it to discover subdomains, probe live services, identify technologies, scan ports, find directories, and collect endpoints for later security testing.
Why use it?
It helps you understand the target’s attack surface so you do not miss reachable parts of the application during an authorized bug bounty or penetration test.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

web-application-recon-and-enumeration scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/process.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Web Application Recon & Enumeration

When to Use

  • As the FIRST STEP in any bug bounty or web application pentest engagement
  • When you need to map the target's complete attack surface
  • When discovering subdomains, hidden endpoints, and technologies
  • When building a target profile before vulnerability testing

Prerequisites

  • Authorized scope and target URLs from bug bounty program
  • Burp Suite Professional (or Community) configured with browser proxy
  • Familiarity with OWASP Top 10 and common web vulnerability classes
  • SecLists wordlists for fuzzing and enumeration

Workflow

Phase 1: Passive Subdomain Enumeration

# subfinder — fast passive subdomain discovery
subfinder -d target.com -all -o subdomains.txt

# amass — comprehensive passive enumeration
amass enum -passive -d target.com -o amass_subs.txt

# assetfinder
assetfinder --subs-only target.com >> subdomains.txt

# Merge and deduplicate
cat subdomains.txt amass_subs.txt | sort -u > all_subs.txt
echo "[+] Total unique subdomains: $(wc -l < all_subs.txt)"

Phase 2: DNS Resolution & HTTP Probing

# Resolve live subdomains
cat all_subs.txt | httpx -silent -status-code -title -tech-detect -o live_hosts.txt

# Check which hosts respond on interesting ports
cat all_subs.txt | httpx -ports 80,443,8080,8443,3000,5000,8000,9090 -silent -o all_ports.txt

# Quick Nmap for service detection
nmap -sV -sC -p 21,22,80,443,3306,5432,8080,8443 -iL live_ips.txt -oA nmap_scan

Phase 3: Technology Fingerprinting

# Wappalyzer-style detection (httpx already does this with -tech-detect)
# Additional: Nuclei technology detection
nuclei -l live_hosts.txt -t technologies/ -o tech_results.txt

# whatweb for detailed fingerprinting
whatweb -i live_hosts.txt --log-brief=whatweb_results.txt

# Check for known CMS
# WordPress: /wp-admin, /wp-content, /xmlrpc.php
# Drupal: /core/CHANGELOG.txt, /user/login
# Joomla: /administrator, /api/index.php

Phase 4: Directory & Content Discovery

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
