Bug bounty programs pay researchers for finding security vulnerabilities. It's a great way to build skills, earn money, and make an impact.
Getting Started
- Learn web security fundamentals (OWASP Top 10)
- Practice on CTF platforms
- Join HackerOne, Bugcrowd, or Intigriti
- Start with VDPs (no bounties, lower competition)
- Read disclosed reports for learning
Reconnaissance
# Subdomain enumeration
subfinder -d target.com | httpx | tee live_subdomains.txt
# JavaScript file collection
cat live_subdomains.txt | waybackurls | grep "\.js$" > js_files.txt
# Parameter discovery
paramspider -d target.comCommon Vulnerability Types
- IDOR (Insecure Direct Object Reference)
- XSS (Cross-Site Scripting)
- Authentication bypass
- Information disclosure
- SSRF (Server-Side Request Forgery)
- Business logic flaws
Report Writing
A good report includes:
- Clear title describing the vulnerability
- Affected endpoint/parameter
- Step-by-step reproduction
- Proof of concept (screenshots, requests)
- Impact statement
- Remediation suggestions
Tips for Success
- Focus on one target deeply rather than many shallowly
- Check mobile apps and APIs (less competition)
- Read the program scope carefully
- Be patient - most hunters earn nothing for months
