No superpowers, I just let AI help me read the code
AI far surpasses humans in "known pattern matching"
Claude Code far outperforms human auditing in its ability to identify classic vulnerability patterns such as insecure deserialization, API endpoints missing permission checks, OAuth2 misconfigurations. Prioritize AI audits using the goals of popular frameworks with the highest output.
Bug report quality is a multiplier factor for bounties
The reports generated by AI ensure structural integrity and consistency. A full report containing "Affected version × Reproduction steps × PoC code × Fix suggestions × CWE mapping" has an average bounty of 3.8x on HackerOne than a simple description.
Mixed model strategy is the optimal solution
Use DeepSeek V4 to do a lot of code scanning and preliminary screening (the cost is only 1/4 of Claude), use Claude Code to do in-depth analysis of key vulnerabilities, and use Semgrep to do regular static analysis. Monthly API costs are controlled at $350-$600.
Execution steps · 1
Determine bounty target and open source dependency list
Select the target project with an open source code base in HackerOne / Bugcrowd and list the GitHub warehouse address and version number of all its open source dependencies. Priority is given to projects using popular frameworks such as Spring, Express, Django, etc., because the vulnerability patterns of these frameworks are fully covered in the AI training data.
Project goals
Use AI programming assistant (Claude Code + DeepSeek V4) to replace the traditional manual penetration testing process, increase the efficiency of security vulnerability mining by 3-5 times, and turn bug bounty from "lucky" to "systematic income".
Identity Anchor
I'm Kevin, an independent security researcher with 5 years of web security experience. Before 2025, I relied on manual penetration testing + Burp Suite to do bug bounty. On average, I found 3-5 valid vulnerabilities every month, and my monthly income was between $3,000-$5,000. In February 2026, I began to introduce the AI tool chain systematically and used Claude Code to assist in code audit and vulnerability analysis. After 3 months, my monthly income stabilized at $8,000-$12,000.
Timeline
- Week 1-2: Learn the code analysis capabilities of Claude Code and use known CVEs of open source projects for verification training
- Week 3-4: Started using AI to analyze the open source dependencies of the bug bounty target and discovered the first 8 vulnerabilities
- Week 5-8: Build automated workflow (n8n + Claude Code + self-developed script), increase vulnerability discovery efficiency by 3 times
- Weeks 9-12: Systematic operation, submitting an average of 15-20 valid vulnerability reports every month, monthly income exceeding $10,000
Scope of application and preconditions
- Have basic web security knowledge (SQL injection, XSS, SSRF, permission bypass, etc.)
- Familiarity with at least one bug bounty platform (HackerOne, Bugcrowd, YesWeHack) -Ability to read GitHub code
- Willing to invest in API fees (Claude Code monthly fee is about $200-$500, depending on usage)
Overview of implementation steps
- Step 1: Determine bounty target and open source dependency list
- Step 2: Use Claude Code to batch audit the target’s open source dependent code
- Step 3: AI-assisted PoC development and verification
- Step 4: Generate a professional vulnerability report and submit it
Data collection and structuring
Do field extraction first, and then do "explanatory copywriting"; only in this way will the vulnerability analysis be systematic, and it will be easier to retrieve and reuse similar vulnerabilities in the future.
