Parth Narula, a security researcher and founder of ScriptJacker, recently secured the Technical University of Applied Sciences Würzburg-Schweinfurt (THWS) and was listed in their Hall of Fame. His work involved identifying critical vulnerabilities, and he shared Proof of Concepts (PoCs) for these findings.

You Should Know: Essential Bug Bounty and Vulnerability Research Techniques

1. Reconnaissance & Enumeration

Before exploiting vulnerabilities, thorough reconnaissance is crucial. Use these tools:

 Subdomain Enumeration 
subfinder -d example.com -o subdomains.txt 
amass enum -d example.com -o amass_results.txt

Port Scanning 
nmap -sV -T4 -p- target.com -oN nmap_scan.txt 
rustscan -a target.com --ulimit 5000 -- -sV -oN rustscan_results.txt

Web Directory Fuzzing 
ffuf -u https://target.com/FUZZ -w /path/to/wordlist.txt -o fuzzing_results.json

2. Exploiting Web Vulnerabilities

Common vulnerabilities include SQLi, XSS, and CSRF. Test them with:

 SQL Injection Testing 
sqlmap -u "https://target.com/page?id=1" --batch --dump

XSS Payload Testing 
python3 xsstrike.py -u "https://target.com/search?q=<script>alert(1)</script>"

CSRF Exploitation 
curl -X POST -d "user=admin&action=delete" https://target.com/admin --cookie "session=malicious_cookie"

3. Post-Exploitation & Reporting

After finding a bug, document it properly:

 Screen Recording (For PoC) 
ffmpeg -f x11grab -s 1920x1080 -i :0.0 output.mp4

Generating Reports 
echo "Vulnerability: SQLi in /login" > report.txt 
echo "Payload: admin' OR 1=1 --" >> report.txt

4. Automating Bug Hunting

Automate repetitive tasks with Bash/Python:

import requests 
target = "https://example.com" 
headers = {"User-Agent": "Mozilla/5.0"} 
response = requests.get(target, headers=headers) 
if "admin" in response.text: 
print("Possible admin panel exposed!")

5. Staying Updated with Security Advisories

Follow CVE databases and exploit repositories:

 Fetch latest CVEs 
curl -s https://cve.mitre.org/data/downloads/allitems.csv | grep "CRITICAL"

Search Exploits 
searchsploit Apache 2.4.49

What Undercode Say

Bug bounty hunting requires persistence, creativity, and deep technical knowledge. Always:
– Stay Ethical: Report vulnerabilities responsibly.
– Document Everything: Maintain detailed logs.
– Automate Wisely: Use scripts to save time.
– Learn Continuously: Follow security researchers like Parth Narula for insights.

Expected Output:

A well-documented bug report with:

  • Vulnerability details
  • Steps to reproduce
  • Impact assessment
  • Suggested fixes
