SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Bug bounty hunting often fails due to shallow recon, theoretical findings, and rejected reports. This Skill provides a disciplined end-to-end methodology that filters out non-exploitable bugs early and produces impact-demonstrated, submission-ready reports. ## Core Features & Use Cases - Full Pipeline Orchestration: Guides recon (subfinder, httpx, nuclei, katana), pre-hunt intelligence from disclosed reports, vulnerability hunting across 30+ classes (IDOR, SSRF, OAuth, XSS), A-to-B chain escalation, and report writing with a 7-question validation gate and CVSS 3.1 scoring. - False-Positive Prevention: Enforces marker discipline, body-diff verification, statistical sampling for timing attacks, and engagement-mode confirmation (bug bounty vs red team vs pentest). - Use Case: Given a HackerOne program scope, run the recon pipeline to enumerate live hosts, fingerprint the tech stack, test IDOR variants across API endpoints with two accounts, chain a discovered bug into account takeover, and generate a human-tone report. ## Quick Start Start a bug bounty hunt on target example.com by running recon, mapping the attack surface, and testing for IDOR and SSRF vulnerabilities.

Frequently Asked Questions about bug-bounty

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I start bug bounty hunting on a new target?

Begin with the recon pipeline: enumerate subdomains with subfinder and assetfinder, probe live hosts with httpx, collect URLs via katana and waybackurls, then run nuclei for known vulnerabilities. Confirm the engagement scope and crown jewels before hunting specific vulnerability classes.

How to test for IDOR vulnerabilities in web APIs?

Create two accounts (attacker and victim), capture all object IDs in requests, then replay the attacker's requests with the victim's session. Test all ten variants including body parameters, GraphQL node queries, batch endpoints, method swapping, and version rollback.

What tools are needed for bug bounty recon automation?

The core toolkit uses Go binaries: subfinder for subdomain enumeration, httpx for host probing, dnsx for resolution, nuclei for template scanning, katana for crawling, and ffuf for fuzzing. Optional tools like sqlmap, trufflehog, and semgrep install on demand.

Why do bug bounty reports get rejected as not applicable?

Most rejections come from theoretical bugs without demonstrated impact, status-code-only bypass claims without body diffs, and single-sample timing outliers. The 7-question gate and body-diff rule filter these before writing any report.

Can this methodology test AI and LLM features?

Yes, it covers AI/LLM testing mapped to the ASI01-ASI10 categories, including chatbot-based XSS chains and IDOR through LLM data access. It treats AI features as additional attack surface within the standard hunting phases.

When should I stop hunting on a target and move on?

Apply the 5-minute rule for unresponsive targets (all 401/403/404) and the one-hour rule for stalled progress. Time-box rabbit holes to 15 minutes and rotate vulnerability classes every 20 minutes when testing yields nothing.
