Bug Bounty Hunting: A Beginner’s Guide

Overview

• Bug bounty hunting can seem daunting for beginners.
• Important to start with a solid foundation in basic tools and techniques.

Foundational Skills

• Basic Tools:
  • Burp Suite for website inspection.
  • Nmap for simple scans.
• Understanding Applications:
  • How applications process inputs and handle session data.
• Learning Approach:
  • Focus on basic skills rather than mastering all tools.

Choosing a Target

• Common Mistakes:
  • Starting with popular platforms like HackerOne or BugCrowd.
  • These are usually dominated by experienced hunters.
• Optimal Approach:
  • Start with websites that have vulnerability disclosure programs (acknowledge but don’t pay).
  • Use Google Dorks or GitHub repositories like BugBountyDorks to find vulnerable targets.
  • Avoid top search results; go deeper into search pages for less examined websites.

Tailoring Your Approach

• Avoid Default Tools and Word Lists:
  • Tailor tools to the specific website (e.g., use Drupal-specific lists for a Drupal site).
  • Tools like GoBuster and Derb can be used for directory brute forcing.
• Smart Hunting:
  • Customize tools and word lists to improve chances of finding hidden vulnerabilities.

Building a Methodology

• Systematic Approach:
  • Begin with an Nmap scan to identify software and version numbers.
  • Cross-reference with sources like ExploitDB or Rapid7 for known vulnerabilities.
  • Be cautious of unreliable online claims about vulnerabilities.
• Directory Brute Forcing:
  • Often overlooked but can reveal hidden files or admin portals.
  • GoBuster is recommended for uncovering hidden directories.

Learning Resources

• Challenges in Sharing Tutorials:
  • Detailed hacking tutorials often get removed from platforms like YouTube.
• Alternative Learning Path:
  • Join CyberFlow's Academy for structured learning.
  • Courses include setting up pen testing labs, mastering Linux commands, website hacking basics, and more advanced techniques.
  • Access to exclusive tutorials, including controversial ones like "How I Hacked My University."

Conclusion

• Bug bounty hunting is about building skills and approaching targets strategically.
• Utilize tailored tools and systematic methodologies for effective bug hunting.
• Consider joining specialized communities for in-depth learning.
