This skill should be used when the user asks to "follow red team methodology", "perform bug bounty hunting", "automate reconnaissance", "hunt for XSS vulnerabilities", "enumerate subdomains", or needs security researcher techniques and tool configurations from top bug bounty hunters.
npx skills add https://github.com/zebbern/claude-code-guide --skill red-team-tools
Implement proven methodologies and tool workflows from top security researchers for effective reconnaissance, vulnerability discovery, and bug bounty hunting. Automate common tasks while maintaining thorough coverage of attack surfaces.
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"
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
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
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
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
Heat Map Priority Areas:
Analysis Questions:
# 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
# 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
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
#!/bin/bash
domain=$1
if [[ -z $domain ]]; then
echo "Usage: ./recon.sh <domain>"
exit 1

mkdir -p "$domain"
# Subdomain enumeration

subfinder -d "$domain" -silent > "$domain/subs.txt"
# Live host discovery

| Issue | Solution |
|-------|----------|
| Rate limited | Use proxy rotation, reduce concurrency |
| Too many results | Focus on specific technology stacks |
| False positives | Manually verify findings before reporting |
| Missing subdomains | Combine multiple enumeration sources |
| API key errors | Verify keys in config files |
| Tools not found | Install Go tools with go install |
Expert malware analyst specializing in defensive malware research, threat intelligence, and incident response. Masters sandbox analysis, behavioral analysis, and malware family identification.

Hunt Host Header Injection — password reset poisoning → ATO, web cache poisoning via unkeyed Host/X-Forwarded-Host, routing-based SSRF (Host picks upstream → cloud metadata/internal services), path-override SSRF/ACL-bypass (X-Original-URL/X-Rewrite-URL), OAuth redirect_uri/issuer poisoning, and absolute-URL link poisoning in emails. High to Critical when it reaches ATO or mass cache poisoning. Built on public Host-header research (PortSwigger 'Practical web cache poisoning' + James Kettle, and the classic password-reset-poisoning class). Use on any forgot-password flow, CDN/reverse-proxy-fronted app, OAuth/OIDC endpoint, or absolute-URL-in-email feature.
Researches malware analysis, CVEs, attribution reports, and hacker community sources. Use when the album subject involves cybersecurity incidents or threat actors.

> Use when the user wants an autonomous ML research loop that explores the space broadly rather than several wild, diverse swings (full rewrites, different architectures/regimes) early, then enters an adaptive phase that picks swing / merge / exploit per iteration — with a hard stagnation guard that bans further small-step exploits once they run too long, forcing a pivot back to a swing or merge. Tracks an approaches.md registry and a move_type per iteration; analyses every run before the next move. One change per iteration; loops forever until interrupted. Not for the standard analysis-first ml-autoresearch (which lets analysis alone choose each change), one-off training runs, or sweeps.
