Red Team Tools

Core Workflow

1. Project Tracking and Acquisitions

Set up reconnaissance tracking:

# Create project structure
mkdir -p target/{recon,vulns,reports}
cd target

# Find acquisitions using Crunchbase
# Search manually for subsidiary companies

# Get ASN for targets
amass intel -org "Target Company" -src

# Alternative ASN lookup
curl -s "https://bgp.he.net/search?search=targetcompany&commit=Search"

2. Subdomain Enumeration

Comprehensive subdomain discovery:

# Create wildcards file
echo "target.com" > wildcards

# Run Amass passively
amass enum -passive -d target.com -src -o amass_passive.txt

# Run Amass actively
amass enum -active -d target.com -src -o amass_active.txt

# Use Subfinder
subfinder -d target.com -silent -o subfinder.txt

# Asset discovery
cat wildcards | assetfinder --subs-only | anew domains.txt

# Alternative subdomain tools
findomain -t target.com -o

# Generate permutations with dnsgen
cat domains.txt | dnsgen - | httprobe > permuted.txt

# Combine all sources
cat amass_*.txt subfinder.txt | sort -u > all_subs.txt

3. Live Host Discovery

Identify responding hosts:

# Check which hosts are live with httprobe
cat domains.txt | httprobe -c 80 --prefer-https | anew hosts.txt

# Use httpx for more details
cat domains.txt | httpx -title -tech-detect -status-code -o live_hosts.txt

# Alternative with massdns
massdns -r resolvers.txt -t A -o S domains.txt > resolved.txt

4. Technology Fingerprinting

Identify technologies for targeted attacks:

# Whatweb scanning
whatweb -i hosts.txt -a 3 -v > tech_stack.txt

# Nuclei technology detection
nuclei -l hosts.txt -t technologies/ -o tech_nuclei.txt

# Wappalyzer (if available)
# Browser extension for manual review

5. Content Discovery

Find hidden endpoints and files:

# Directory bruteforce with ffuf
ffuf -ac -v -u https://target.com/FUZZ -w /usr/share/seclists/Discovery/Web-Content/raft-medium-directories.txt

# Historical URLs from Wayback
waybackurls target.com | tee wayback.txt

# Find all URLs with gau
gau target.com | tee all_urls.txt

# Parameter discovery
cat all_urls.txt | grep "=" | sort -u > params.txt

# Generate custom wordlist from historical data
cat all_urls.txt | unfurl paths | sort -u > custom_wordlist.txt

6. Application Analysis (Jason Haddix Method)

Heat Map Priority Areas:

1. File Uploads - Test for injection, XXE, SSRF, shell upload
2. Content Types - Filter Burp for multipart forms
3. APIs - Look for hidden methods, lack of auth
4. Profile Sections - Stored XSS, custom fields
5. Integrations - SSRF through third parties
6. Error Pages - Exotic injection points

Analysis Questions:

• How does the app pass data? (Params, API, Hybrid)
• Where does the app talk about users? (UID, UUID endpoints)
• Does the site have multi-tenancy or user levels?
• Does it have a unique threat model?
• How does the site handle XSS/CSRF?
• Has the site had past writeups/exploits?

7. Automated XSS Hunting

# ParamSpider for parameter extraction
python3 paramspider.py --domain target.com -o params.txt

# Filter with Gxss
cat params.txt | Gxss -p test

# Dalfox for XSS testing
cat params.txt | dalfox pipe --mining-dict params.txt -o xss_results.txt

# Alternative workflow
waybackurls target.com | grep "=" | qsreplace '"><script>alert(1)</script>' | while read url; do
    curl -s "$url" | grep -q 'alert(1)' && echo "$url"
done > potential_xss.txt

8. Vulnerability Scanning

# Nuclei comprehensive scan
nuclei -l hosts.txt -t ~/nuclei-templates/ -o nuclei_results.txt

# Check for common CVEs
nuclei -l hosts.txt -t cves/ -o cve_results.txt

# Web vulnerabilities
nuclei -l hosts.txt -t vulnerabilities/ -o vuln_results.txt

9. API Enumeration

Wordlists for API fuzzing:

# Enumerate API endpoints
ffuf -u https://target.com/api/FUZZ -w /usr/share/seclists/Discovery/Web-Content/api/api-endpoints.txt

# Test API versions
ffuf -u https://target.com/api/v1/FUZZ -w api_wordlist.txt
ffuf -u https://target.com/api/v2/FUZZ -w api_wordlist.txt

# Check for hidden methods
for method in GET POST PUT DELETE PATCH; do
    curl -X $method https://target.com/api/users -v
done

10. Automated Recon Script

#!/bin/bash
domain=$1

if [[ -z $domain ]]; then
    echo "Usage: ./recon.sh <domain>"
    exit 1
fi

mkdir -p "$domain"

# Subdomain enumeration
echo "[*] Enumerating subdomains..."
subfinder -d "$domain" -silent > "$domain/subs.txt"

# Live host discovery
echo "[*] Finding live hosts..."
cat "$domain/subs.txt" | httpx -title -tech-detect -status-code > "$domain/live.txt"

# URL collection
echo "[*] Collecting URLs..."
cat "$domain/live.txt" | waybackurls > "$domain/urls.txt"

# Nuclei scanning
echo "[*] Running Nuclei..."
nuclei -l "$domain/live.txt" -o "$domain/nuclei.txt"

echo "[+] Recon complete!"

Quick Reference

Essential Tools

Key API Endpoints to Check

/api/v1/users
/api/v1/admin
/api/v1/profile
/api/users/me
/api/config
/api/debug
/api/swagger
/api/graphql

XSS Filter Testing

<!-- Test encoding handling -->
<h1><img><table>
<script>
%3Cscript%3E
%253Cscript%253E
%26lt;script%26gt;

Constraints

• Respect program scope boundaries
• Avoid DoS or fuzzing on production without permission
• Rate limit requests to avoid blocking
• Some tools may generate false positives
• API keys required for full functionality of some tools

Examples

Example 1: Quick Subdomain Recon

subfinder -d target.com | httpx -title | tee results.txt

Example 2: XSS Hunting Pipeline

waybackurls target.com | grep "=" | qsreplace "test" | httpx -silent | dalfox pipe

Example 3: Comprehensive Scan

# Full recon chain
amass enum -d target.com | httpx | nuclei -t ~/nuclei-templates/
