Bug bounty programs are a great way to identify security vulnerabilities and earn rewards. Successful hunters use a combination of manual testing, automated tools, and deep knowledge of common vulnerabilities. Below are key techniques and tools used in bug bounty hunting.

You Should Know:

1. Reconnaissance & Enumeration

Before attacking, gather as much information as possible:

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

Port Scanning 
nmap -sV -p- -T4 target.com -oN nmap_scan.txt

Wayback Machine Data 
waybackurls example.com > urls.txt

2. Automated Vulnerability Scanning

Use tools to find low-hanging vulnerabilities:

 SQL Injection & XSS Scanning 
sqlmap -u "https://example.com/search?id=1" --batch --risk=3 
xsstrike -u "https://example.com/search?q=test"

CMS Scanning 
wpscan --url https://example.com --enumerate p,t,u

3. Manual Testing for Logic Flaws

Automation won’t catch everything. Test for:

  • IDOR (Insecure Direct Object Reference)
  • Business Logic Bypass
  • JWT Tampering 
    JWT Manipulation 
echo "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c" | jwt_tool -t https://example.com/api -cv

4. Exploiting APIs

APIs are a goldmine for bugs:

 API Fuzzing 
ffuf -u "https://api.example.com/v1/users/FUZZ" -w wordlist.txt -mc 200

GraphQL Testing 
graphqlmap -u https://example.com/graphql -i

5. Post-Exploitation Reporting

After finding a bug, document it properly:

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

Proof-of-Creation 
echo "Vulnerable: https://example.com/profile?id=123" > poc.txt

What Undercode Say

Bug bounty hunting requires persistence, creativity, and continuous learning. Focus on:
– OWASP Top 10 Vulnerabilities
– New CVEs (Common Vulnerabilities & Exposures)
– Real-world exploitation techniques

Expected Output:

A well-documented bug report with:

  • Clear steps to reproduce
  • Impact assessment
  • Suggested fixes

Prediction

With the rise of AI-powered security tools, bug bounty hunters will increasingly rely on automation-assisted manual testing to uncover complex vulnerabilities.
