How To Start Bug Hunting In 2025

 

 Introduction to Bug Bounty Hunting

Bug bounty hunting is all about finding security flaws in software, applications, and websites to help companies fix them before cybercriminals can exploit them. Ethical hackers, also called security researchers, get paid for responsibly reporting these vulnerabilities.

If you're passionate about ethical hacking and want to earn legally, bug bounty hunting is an excellent career choice.

🛠 Skills Required for Bug Bounty Hunting

Before jumping in, you need to build a strong cybersecurity foundation. Here are some key skills:

1️⃣ Networking & Web Fundamentals

  • Understand how the internet works (IP, DNS, HTTP, TCP/IP).
  • Learn about servers, clients, and databases.

2️⃣ Web Application Security

  • Get familiar with how websites function (HTML, CSS, JavaScript, APIs).
  • Study common web vulnerabilities like:
    • SQL Injection (SQLi)
    • Cross-Site Scripting (XSS)
    • Cross-Site Request Forgery (CSRF)
    • Authentication & Session Management Issues

3️⃣ Programming Skills

  • Learn Python, JavaScript, or Bash scripting for automation.
  • Develop the ability to read and modify source code.

4️⃣ Hands-on Experience with Tools

  • Burp Suite – Web security testing
  • Nmap – Network scanning
  • Nikto – Web server vulnerability detection
  • Metasploit – Penetration testing

🛠 How to Start Bug Bounty Hunting (Step-by-Step Guide)

Step 1: Practice on Legal Hacking Platforms

Before testing real-world applications, practice on these ethical hacking platforms:

  • Hack The Box (HTB) – Real-world hacking scenarios
  • TryHackMe – Beginner-friendly lessons
  • PortSwigger Academy – Best place to learn Burp Suite

Step 2: Join Bug Bounty Platforms

Once you've gained basic skills, sign up for these bug bounty platforms:

  • HackerOne → The largest bug bounty platform
  • Bugcrowd → Offers paid programs & private invitations
  • Synack Red Team → Exclusive private programs
  • Open Bug Bounty → Free and open vulnerability disclosure

 Tip: Start with public programs before applying for private ones.

Step 3: Choose Your First Target

  • Pick a target you understand well (websites, mobile apps, or APIs).
  • Read the program’s scope and rules carefully.
  • Look for common vulnerabilities like:
    • IDOR (Insecure Direct Object References)
    • XSS (Cross-Site Scripting)
    • CSRF (Cross-Site Request Forgery)

Step 4: Write a Professional Bug Report

If you find a vulnerability, make sure your report includes:

  • Title: Clear and concise description of the issue.
  • Steps to Reproduce: A step-by-step guide to replicate the bug.
  • Impact: Explanation of how the vulnerability could harm the system.
  • Proof of Concept (PoC): Screenshots or videos demonstrating the bug.

 Tip: A well-written report increases your chances of getting a bounty!

 How Much Can You Earn from Bug Bounties?

Your earnings depend on the severity of the bug and the company’s payout policy. Here’s what you can expect:

  • Low Severity (Information Disclosure): $50 - $500
  • Medium Severity (XSS, CSRF): $500 - $2,000
  • High Severity (SQL Injection, IDOR, Authentication Bypass): $2,000 - $10,000
  • Critical (RCE, SSRF, Full Account Takeover): $10,000 - $50,000+

 Many ethical hackers earn over $100K per year through bug hunting!

 Pro Tips for Success in Bug Bounty Hunting

  • Start Small: Focus on easy vulnerabilities before tackling complex ones.
  • Learn from Past Reports: Read previous bug reports on platforms like HackerOne.
  • Engage with the Community: Join Discord groups and follow cybersecurity experts on Twitter.
  • Be Patient and Persistent: Finding high-paying bugs takes time and experience.
