Bug Bounty for Beginners: How to Find Your First Bug and Get Paid (2026)

Bug bounty hunting is one of the most direct ways to monetise cybersecurity skills on real-world systems — legally, with written permission, and with the potential to earn serious money. Over $1 billion in bounties has been paid out on HackerOne alone since the platform launched.

This guide covers everything a beginner needs to go from zero to first paid report.

What Is Bug Bounty Hunting?

A bug bounty program is an arrangement where a company invites security researchers to find vulnerabilities in their systems and rewards them with cash. The company publishes a policy document defining:

• Scope — which domains, apps, or APIs you can test
• Out-of-scope — assets you must not touch
• Reward ranges — how much each severity level pays
• Rules of engagement — what testing techniques are allowed

You find a vulnerability, write a clear report, submit it through the platform, and if it's valid and in-scope, you get paid.

Severity Levels and Typical Payouts

Severity	Examples	Typical Range
Critical (P1)	Remote Code Execution, SQLi on production DB	$5,000–$100,000+
High (P2)	IDOR with broad impact, Auth Bypass	$1,000–$10,000
Medium (P3)	Stored XSS, SSRF, Privilege Escalation	$200–$2,000
Low (P4)	Open Redirect, Info Disclosure	$50–$500
Informational	Minor config issue	Usually $0

Where to Hunt: Best Platforms

HackerOne

The largest bug bounty platform. Hosts programs from Google, Microsoft, Twitter, US Department of Defense, and thousands more. Public programs are open to anyone — create a free account and start submitting. Private programs (invite-only) open up as your reputation grows.

Bugcrowd

Strong US and enterprise presence. Has a beginner-friendly "Crowd Academy" learning section. Their trust score system gates access to private programs.

Intigriti

Europe's leading platform, with strong representation of EU companies. Great for finding programs with less competition than US-heavy platforms.

Open Bug Bounty

Free, community-based platform focused on responsible disclosure. Good for practice but rewards are recognition only.

Skills You Need Before Starting

Bug bounty is not the place to start learning cybersecurity from scratch. You need a foundation:

Non-negotiable basics

• HTTP fundamentals: requests, responses, headers, cookies, sessions
• OWASP Top 10: understand what each vulnerability class is and how it arises — this is your hunting checklist
• Browser DevTools: how to inspect requests, modify parameters, intercept responses
• Burp Suite basics: proxying traffic, Repeater, basic Intruder usage

Recommended before your first real program

• Complete the Jr Penetration Tester path on TryHackMe
• Understand all 10 OWASP Top 10 vulnerability classes
• Do 20+ CTF web challenges to build instincts
• Set up Burp Suite and practise on DVWA or PortSwigger Web Academy (free)

How to Find Your First Bug

Step 1: Choose the Right Program

Don't target Google or Apple as a beginner — thousands of experienced hunters watch those assets 24/7. Look for:

• Programs with a wide scope (many assets = more attack surface)
• Programs that are recently launched (less competition)
• Companies with newer web apps or mobile apps (more likely to have issues)
• Programs marked "accepting reports" with recent activity

Filter on HackerOne by: Bounties > $0, All programs, sort by "Newest."

Step 2: Understand the Target

Before touching anything:

1. Read the entire policy document — memorise what's in and out of scope
2. Map the application: what does it do? Who are the users? What data does it handle?
3. Create a test account (never test on real user data)
4. Walk through every feature as a normal user first

Step 3: Hunt Methodically by OWASP Category

Start with the highest-impact, easiest-to-find classes:

Broken Access Control (IDOR) Change numeric IDs in requests. Can you view another user's data by changing ?user_id=123 to ?user_id=124? Can you access admin endpoints without admin privileges?

XSS (Cross-Site Scripting) Inject <script>alert(1)</script> in every input that reflects back to the page. Check search fields, profile names, comments, error messages.

Authentication Issues Test password reset flows — is the token predictable? Does it expire? Can you reuse it? Test account enumeration via error messages.

Business Logic Flaws These are unique to each app and automated tools miss them entirely. Think: can you skip payment steps? Apply a coupon more than once? Access features before completing required steps?

Step 4: Write a Report That Gets Accepted

A poor report gets triaged as "Informational" even if the bug is real. A great report gets paid. Structure:

**Summary**: One sentence — what the bug is and its impact.

**Steps to Reproduce**:
1. Log in as test user at [URL]
2. Navigate to [specific page]
3. Intercept the request with Burp Suite
4. Change parameter X from "A" to "B"
5. Observe that [impact]

**Impact**: What can an attacker do? Be specific. "Attacker can read any user's private messages" beats "data exposure."

**Evidence**: Screenshots or video of the full reproduction. Include the raw HTTP request/response.

**Suggested Fix**: Optional but appreciated.

Common Beginner Mistakes

• Testing out of scope: Instant ban. Check the scope first. Every time.
• Reporting without full reproduction: If the triage team can't reproduce it, it won't be paid.
• Duplicates: Someone found it before you. Check if the program has a public list of known issues.
• Automated scanning without permission: Most programs explicitly ban mass scanning tools. Read the policy.
• Giving up after first rejection: Triage teams make mistakes. If you're confident in your report, ask for clarification politely.

Building Your Reputation

Your HackerOne reputation score unlocks private programs, which have less competition and often higher payouts. Build it by:

1. Submitting quality reports, not quantity
2. Being professional and responsive with triage teams
3. Participating in live hacking events (HackerOne runs these regularly)
4. Getting CVEs assigned for significant findings

Realistic Timeline

Month	What to focus on
1–3	Learn OWASP Top 10, PortSwigger Academy, DVWA
3–6	First program — wide scope, expect duplicates
6–12	First paid P3/P4 reports, refine methodology
12–24	Specialise (APIs, mobile, OAuth), aim for P1/P2

Bug bounty rewards patience. The researchers earning $10k+/month have typically been hunting for 3–5 years and have deep specialised knowledge in one or two vulnerability classes.
