Introduction

This article delves into the fascinating world of bug bounty hunting, featuring insights from Vicky Lee, author of the book Bug Bounty Bootcamp. The content was originally derived from her conversation with David Bumble, where Vicky explains the fundamentals of bug bounties, sharing her journey, and offering practical advice for beginners. The article also covers a demo on an Insecure Direct Object Reference (IDOR) vulnerability.

Vicky Lee’s Background

Vicky Lee is a renowned author in the bug bounty community. She wrote the book Bug Bounty Bootcamp to prepare people with little to no experience in bug bounties. The book aims to guide readers in understanding web vulnerabilities and exploiting them responsibly.

Introduction to Bug Bounties

Bug bounty programs are initiatives where companies reward ethical hackers for finding vulnerabilities in their applications. These programs are beneficial for both companies and hackers. Companies get their security issues identified and fixed, while hackers gain experience and monetary rewards.

Why Bug Bounties?

Vicky started writing about web security and bug bounties to connect with like-minded individuals. Her blog initially served as a platform to share her experiences and to motivate herself. Eventually, this led her to compile her blog posts and notes into a book aimed at helping beginners.

How to Start with Bug Bounties

Reading and Learning

  • Books and Online Resources: Vicky recommends starting with books on web security to understand the basics of how the web works and common vulnerabilities.
  • Online Labs: Platforms like PortSwigger Academy offer practical labs where beginners can practice hacking in a controlled environment.

Choosing the Right Bug Bounty Programs

  • Beginner-Friendly Programs: Vicky suggests starting with programs that offer no monetary rewards but are less competitive, such as Vulnerability Disclosure Programs (VDPs).
  • Platforms: Websites like HackerOne, Bugcrowd, and Integrity offer various programs suited for different levels of expertise.

Practical Advice for Beginners

Key Vulnerabilities to Focus On

  • IDOR (Insecure Direct Object Reference): These vulnerabilities are straightforward and can be very impactful.
  • Business Logic Flaws: These are harder to automate and often require a deep understanding of how an application works.
  • Cross-Site Scripting (XSS): This is another common vulnerability that can have severe implications.

The Importance of Specialization

  • Finding a niche can significantly increase your chances of success. Whether it's Recon, Business Logic Flaws, or API security, specializing in a specific area can set you apart from the competition.

Essential Tools

  • Burp Suite: This is a popular tool among bug bounty hunters. The free Community edition is often sufficient to get started.

Learning to Code

  • Programming Languages: Vicky suggests learning Python and Bash scripting as they are useful for automating tasks.
  • Automation can save a lot of time, allowing hunters to focus on finding unique vulnerabilities.

Demo: IDOR Vulnerability

What is IDOR?

IDOR stands for Insecure Direct Object Reference. It's a type of access control vulnerability where an application does not adequately check if a user is authorized to access a specific resource.

Example Walkthrough

Vicky provides a detailed demo using PortSwigger Academy's web Security lab. She demonstrates how to manipulate user IDs and access unauthorized information.

Steps:

  1. Identifying Potential Vulnerabilities: By examining URLs and request parameters.
  2. Using Burp Suite: Intercepting and altering web traffic to test for vulnerabilities.
  3. Validating Findings: Ensuring that unauthorized access to resources can be achieved and documenting the findings.

Conclusion

Bug bounty hunting is a rewarding field, both intellectually and financially. Vicky’s journey from a computer science student to a recognized figure in the bug bounty community shows that anyone with dedication can succeed. By starting with foundational knowledge, practicing on labs, and gradually moving to real-world applications, beginners can effectively transition into proficient bug bounty hunters.

For more detailed advice, practical exercises, and advanced techniques, Vicky's book Bug Bounty Bootcamp serves as an excellent guide.
