How to Find Your First Bug: A Step-by-Step Bug Bounty Guide for Beginners

Key takeaways

• Learn before you hunt: HTTP, how web apps work, and the OWASP Top 10. Then practise in labs, not on live sites.
• The programme policy is your permission. Read scope, rules and safe-harbour terms, and stay inside them.
• Beginners often find issues in access control, information exposure and misconfiguration. Duplicates are common.
• A good report is clear, reproducible and shows impact without harming data.
• No one can promise earnings or a timeline. Treat bounty as a skill-building path first.

What is bug bounty hunting?

A bug bounty programme is an invitation from an organisation to security researchers to find and report vulnerabilities in defined systems under published rules. Valid, new findings may earn a reward, recognition or both. It is ethical hacking with permission, and only inside the programme's scope.

Note on this article

This page used to be written as a personal story. A guide is more useful and more honest, so it is now a method you can follow. Nothing here describes a specific finding by WebAsha.

Step 1: Build the foundation

• How HTTP works: requests, responses, headers, cookies, sessions.
• How logins, tokens and permissions work.
• The OWASP Top 10: broken access control, injection, cryptographic failures, security misconfiguration and others.
• A proxy tool such as Burp Suite or OWASP ZAP to see and edit requests.
• Basic Linux, browser developer tools and notes.

Step 2: Practise on legal labs

Do not learn on live sites. Use the free PortSwigger Web Security Academy labs, or run DVWA or OWASP Juice Shop in your own VM. Aim to explain each bug: what causes it, how it is exploited in the lab and how developers fix it.

Step 3: Choose a programme

Programmes are listed on bug bounty platforms and on companies' own security pages (look for a security.txt file or a "responsible disclosure" page). For a first programme, choose one with a broad scope, clear rules, and a record of responding. Read:

• In-scope and out-of-scope assets. Test nothing else.
• Excluded vulnerability types (for example denial of service, social engineering).
• Safe harbour language that says the company will not take legal action if you follow the rules.
• Testing limits: rate limits, accounts you may create, data you must not access.

Step 4: Reconnaissance within scope

Map the in-scope application: pages, login flows, user roles, API endpoints, technologies in use. Browse like a user first, with the proxy running. Notes now save days later. Do not use aggressive automated scanners if the rules prohibit them.

Step 5: Look for issues beginners can find

Stop as soon as you have proof. Do not download other users' data, change real records, or keep exploring after you have shown the issue.

Step 6: Validate and document

Reproduce the issue twice. Record the exact URL, request, response and steps. Take a screenshot or short screen recording. Decide the real impact in plain words: what could an attacker do, to whom, and how easily?

Step 7: Write the report

1. Title: short and specific ("IDOR in /api/orders exposes other users' invoices").
2. Summary: two sentences.
3. Steps to reproduce: numbered, with test account details.
4. Impact: what is exposed or possible.
5. Suggested fix: brief and practical.
6. Evidence: request, response, screenshot.

Step 8: Handle the response

Triage can take time. Duplicates, "informational" and "not applicable" results are normal, especially at first. Stay polite, answer follow-up questions and do not publish details before the organisation allows it. Learn from each response.

Is bug bounty hunting legal?

It is legal only within a programme's published scope and rules. Testing outside scope, or on sites with no programme, can be unauthorised access under India's IT Act. If you find a problem accidentally on a site with no programme, stop and consider reporting to the organisation or to CERT-In (cert-in.org.in) instead of probing further.

Can beginners earn money from bug bounties?

Some do, but income is irregular and not guaranteed. Competition is high, and duplicates earn nothing. Many professionals treat bounty as a way to build skills and a reputation that supports a job or consulting career. Read bug bounty versus penetration testing to compare paths.
