How to Use Claude for Bug Bounty Work

Claude is useful in authorized bug bounty work for three things: reading and summarizing program scope documents, helping organize findings for triage and clarity, and drafting reports before your own review and submission. All three tasks save time and reduce the risk of missing something in a long scope document or a disorganized notes file.

The work described here applies only to authorized bug bounty programs — programs with a published scope document that permits security testing within defined boundaries. Tools like fenbs help track findings, scope decisions and follow-up tasks across sessions, so nothing falls through when you switch contexts.

Reading and summarizing program scope

Bug bounty program scope documents define what is in scope, what is out of scope, the testing methods permitted, the disclosure timeline and the submission requirements. These documents can be long, and misreading scope leads to reports that are out of scope — wasted effort and a poor relationship with the program.

Paste the scope document into Claude and ask it to produce a structured summary: in-scope assets and domains, out-of-scope items, permitted testing methods, prohibited actions and submission requirements. Then verify the summary against the original. Scope documents sometimes use precise language that affects interpretation; check the original for anything that might be ambiguous.

A useful follow-up prompt: "Based on this scope document, is testing [specific action or method] permitted?" Claude will give a clear yes or no with its reasoning. Review its reasoning against the original text before relying on it.

Organizing findings for clarity

During a testing session, notes accumulate quickly and can become disorganized. Claude can help structure a set of raw finding notes into a consistent format: vulnerability type, affected asset, reproduction steps, observed behavior, potential impact. That structure makes triage faster and report drafting much easier.

Give Claude your raw notes for a single finding and ask it to organize them into a structured format. Review each structured finding carefully: Claude may reinterpret a reproduction step or infer an impact that you did not observe directly. The final finding record should reflect what you actually observed and tested, not what Claude inferred.

Deduplication is another useful task. If you have found several related issues, ask Claude to compare them and identify whether they are the same root cause or genuinely separate vulnerabilities. Program policies on duplicates and related issues vary; check the scope document before submitting.

Drafting reports before submission

A strong bug bounty report is clear, concise and reproducible. It describes the vulnerability, the reproduction steps, the observed impact and a suggested fix, in language a developer who did not find the bug can follow. Claude is good at turning a structured finding into a readable draft.

Give Claude the structured finding and ask it to draft a submission report in the format the program requests. Read the draft in full before submitting. Check that every reproduction step is accurate, that the impact claim is what you actually observed (not what Claude extrapolated), and that no out-of-scope information is included.

Do not let Claude add impact claims you have not verified. Inflated severity claims are a common report quality issue and can damage your reputation with a program. If you observed information disclosure but did not verify account takeover, the report should describe information disclosure.

Scope decisions and what to record

During a program, you make decisions about scope interpretation: is this subdomain covered by the wildcard? Does "no automated scanning" prohibit this particular tool? Record those decisions as you make them. If a program's scope language is ambiguous, contact the program through the official channel and record the response.

Recording scope decisions protects you. If a program later disputes whether an asset was in scope, your record of having interpreted the scope and acted on that interpretation is evidence of good faith. Keep that record outside any one AI session.

What Claude should not do in bug bounty work

Do not use Claude to generate exploit code, payloads or attack chains for submission in a report without your own verification that they work as described. Do not ask Claude to help test out-of-scope assets or devise ways around program rules. Do not paste other researchers' unreleased findings into Claude.

Claude does not know your program's current scope — programs update their scope documents. Always work from the current published scope document, not Claude's general knowledge of what is typically in scope for this type of program.

How to do this with fenbs

1. Create a free account and set up a project for the bug bounty program.
2. Add the program scope summary as a context note — in-scope assets, permitted methods, submission requirements. Update it when the program updates their scope.
3. Add each finding as a task. Record the vulnerability type, asset, reproduction steps and observed impact. Move it through To Do, In Progress and Done as you verify, draft and submit.
4. Record scope interpretation decisions in Decisions and rules. Note ambiguous scope language and any clarifications you received from the program.
5. Connect Claude or another supported assistant from Integrations and ask it to read the project context before working on a finding or report draft.

fenbs does not store exploit code or vulnerability details that should not leave your environment. Use it for the project management layer — tracking what you found, what you submitted and what the program responded — not as a repository for sensitive technical findings.
