Becoming a Bug Bounty Hunter: Where to Study and What to Learn

Bug bounty hunting has gained significant popularity in recent years, with more individuals aspiring to become successful bug bounty hunters. If You are interested in entering this field but are unsure about Where To start or what to learn, this article is for you. We will guide you through the essential resources and learning paths that will fast-track your Journey to becoming a proficient bug bounty hunter. So, let's dive in!

1. Introduction

Before we begin, it's important to understand the basics of bug bounty hunting. Bug bounty hunters are individuals who actively search for and report vulnerabilities in web applications and systems to the respective organizations in exchange for monetary rewards. To be successful in this field, you need to have a strong knowledge of web development, programming languages, and security vulnerabilities.

2. Web Development Basics

To kick-start your bug bounty hunting journey, it is crucial to have a solid foundation in web development basics. This includes understanding HTML, CSS, and JavaScript. Although CSS is not essential for bug bounty hunting, it's beneficial to have some knowledge as it is often intertwined with HTML. You can start learning these languages through various resources, such as YouTube tutorials or online courses, to gain a thorough understanding.

3. Learning Python

When it comes to programming languages, JavaScript and Python are highly recommended for bug bounty hunters. JavaScript is important for reading and de-obfuscating code, while Python is widely used and relatively easy to learn. By investing three to six months in learning web development basics, you will develop a strong foundation in HTML, CSS, and JavaScript. Once you are comfortable with JavaScript, branching out to learn Python will become much easier.

4. Understanding Linux

While coding is a crucial skill for bug bounty hunting, it is equally important to familiarize yourself with Linux. Linux is an operating system commonly used in the field of cybersecurity and offers a wide range of tools and capabilities. Learning the basics of Linux will enhance your ability to work efficiently in command-line environments and handle various security tools. You can start your Linux journey by exploring Linux Fundamentals on platforms like TryHackMe to gain hands-on experience.

5. Basic Web Exploits

To excel in bug bounty hunting, you must understand the fundamental web exploits that hackers commonly exploit. Platforms like PortSwigger, OverTheWire, and HackTheBox provide a plethora of interactive labs and challenges focusing on web application penetration testing. These resources will provide you with the opportunity to practice and refine your skills in identifying and exploiting vulnerabilities such as SQL injection, cross-site scripting (XSS), and more.

6. Cross-Site Scripting (XSS)

Cross-site scripting (XSS) is a prevalent vulnerability that every bug bounty hunter should be familiar with. XSS allows attackers to inject malicious scripts into web pages viewed by other users, potentially compromising their security. Platforms like Juice Shop and TryHackMe offer specific labs and challenges dedicated to XSS that will enable you to practice identifying and exploiting XSS vulnerabilities effectively.

7. External Entity Injection (XXE)

External Entity Injection (XXE) is another critical vulnerability to understand as a bug bounty hunter. XXE allows an attacker to extract sensitive data or execute remote code by exploiting the way XML parsers handle external entities. TryHackMe provides labs focused on XXE vulnerabilities, offering you an excellent opportunity to hone your skills in identifying and exploiting XXE vulnerabilities effectively.

8. File Upload Vulnerabilities

File Upload vulnerabilities are frequently targeted by attackers to achieve remote code execution or compromise the integrity of a system. Platforms like TryHackMe and HackTheBox have labs specifically designed to practice identifying and exploiting file upload vulnerabilities. By mastering this skill, you will be better equipped to uncover critical vulnerabilities in web applications that have file upload functionality.

9. Remote File Inclusion (RFI) and Local File Inclusion (LFI)

Remote File Inclusion (RFI) and Local File Inclusion (LFI) are vulnerabilities that allow an attacker to include external or local files, respectively, into web applications. By exploiting these vulnerabilities, an attacker can Read sensitive files, execute arbitrary code, or gain unauthorized access to a system. TryHackMe provides labs focusing on RFI and LFI, allowing you to practice identifying and exploiting these vulnerabilities in a controlled environment.

10. Server-Side Request Forgery (SSRF)

Server-Side Request Forgery (SSRF) is a vulnerability that enables attackers to manipulate server-side requests made by the target application. Understanding SSRF and learning how to identify and exploit it is a valuable skill for bug bounty hunters. Expand your knowledge by practicing SSRF vulnerabilities on platforms like TryHackMe and PortSwigger.

11. Certifications for Bug Bounty Hunting

While certifications can be beneficial for career advancement in cybersecurity, they are not a mandatory requirement for bug bounty hunting. Practical knowledge and real-world experience hold more value than certifications. However, if you aspire to work as a web application penetration tester in the future, certifications such as Certified Ethical Hacker (CEH) or Offensive Security Certified Professional (OSCP) can enhance your credibility.

12. Reading Bug Bounty Reports on HackerOne

A great way to improve your bug hunting skills is by studying and analyzing real bug bounty reports. Platforms like HackerOne provide transparency by hosting public bug bounty reports, allowing you to learn from experienced hunters. Reading these reports will expose you to different vulnerabilities, explain the techniques used to discover them, and increase your understanding of bug hunting methodologies.

13. Conclusion

Embarking on a journey to become a bug bounty hunter requires dedication, continuous learning, and hands-on practice. By following the learning path outlined in this article, you will acquire essential skills in web development, programming languages, and exploiting web vulnerabilities. Remember, bug bounty hunting is a challenging yet rewarding field, so embrace the learning process and keep honing your skills. Good luck on your bug bounty hunting endeavors!
