Bug bounty programs are efforts where Companies, such as Mozilla, Facebook, Yahoo!, Google, Reddit, Square, Microsoft, and even the United States Department of Defense, give prizes for reporting bugs, notably security exploits and vulnerabilities. These programs help developers detect and repair vulnerabilities before they lead to widespread abuse or data breaches, making the internet safer. For beginners, the good news is that you can learn bug bounty for free, and this guide will show you how, starting with the basics and progressing to finding your first bug.
What is Bug Bounty?
A bug bounty program is a crowdsourcing initiative that rewards individuals, generally ethical hackers, for identifying and reporting software problems, notably security issues. These hunters, known as bug bounty hunters, use their expertise to uncover defects like cross-site scripting (XSS) or SQL injection, and firms compensate them based on the severity of the problem, with payments ranging from a few hundred to thousands of dollars, depending on the software.
The procedure works as follows: hunters locate a vulnerability, record it in a bug report with enough detail for the company to reproduce and validate it, then submit it using the program’s platform. Once confirmed, the hunter receives a reward, which can be monetary or recognition, such as being named in a hall of fame.
How to Start Bug Bounty as a Beginner
To embark on your bug bounty quest, you need some core information. The qualifications include:
- Basic networking: Understand concepts like IP addresses, MAC addresses, and the OSI stack, which are crucial for identifying network-related vulnerabilities.
- Linux: Familiarity with Linux commands and operations, as many hacking tools run on Linux environments.
- Scripting: Basic knowledge of scripting languages like Python, JavaScript, HTML, and CSS, which are essential for web application testing.
- Cybersecurity concepts: Learn about common web vulnerabilities like XSS, SQL injection, server-side request forgery (SSRF), and others.
Step-by-Step Roadmap for Beginners
- Learn the Basics: Start with online resources like GeeksforGeeks for networking and web programming fundamentals. Focus on HTTP, FTP, and TLS protocols, which are often exploited in bug bounties.
- Set Up Your Environment: Install a penetration testing distribution like Kali Linux, which comes with several pre-installed tools. Familiarize yourself with the UI and fundamental commands.
- Practice with Free Resources: Use platforms like PortSwigger Web Security Academy, which offers free, interactive labs, and TryHackMe, which has free rooms for beginners. Participate in Capture The Flag (CTF) events on CTFTime or PicoCTF to build practical skills.
- Join Bug Bounty Programs: Start with beginner-friendly programs on platforms like HackerOne, Bugcrowd, or Intigriti. Look for programs with open registration policies, like HackerOne, where you can create an account without vetting.

- Write Good Reports: Clear, concise reports with steps to reproduce, impact assessment, and remedy recommendations maximize your chances of getting rewarded. Platforms like HackerOne provide templates for instruction.
How to Find Your First Bug and Earn Money
Finding your first bug can be a milestone. Here’s a step-by-step example for finding an XSS vulnerability, a common starting point for beginners:
- Choose a Bug Bounty Program: Select a program on HackerOne or Bugcrowd that allows XSS reports, preferably with beginner-friendly targets.
- Look for Input Fields: Examine the website for text input boxes, such as search bars, comment sections, or form fields.
- Inject XSS Payload: Enter a simple payload like <script>alert(‘XSS’);</script> into the input field and submit it.
- Check for Reflection: See if the payload is reflected back in the page’s response, indicating potential XSS.
- Test Exploitability: If reflected, check if it executes JavaScript (e.g., does the alert pop up?). Use tools like Burp Suite to intercept and manipulate requests.
- Write a Detailed Report: Document the steps to recreate, the impact (e.g., potential for stealing cookies), and advice for fixing (e.g., input sanitization). Submit it on the program’s site.
- Get Rewarded:If validated, you’ll earn a reward, which might range from a few hundred to thousands of dollars, depending on severity.
