Bug Bounty Hunter v1 - Fine-Tuning Dataset

The largest public dataset for training AI models on bug bounty hunting expertise.

Overview

52,743 instruction-response pairs covering 40+ vulnerability types across 6 categories, extracted from real-world bug bounty writeups and security research.

Dataset Summary

This dataset is designed to fine-tune language models to become expert bug bounty hunters. Each example contains a technical instruction and a detailed response drawn from thousands of real vulnerability writeups, security blogs, CVE analyses, and methodology guides.

Use Cases

• Fine-tune chat models for bug bounty expertise
• Train vulnerability classifiers
• Teach LLMs security testing methodology
• Build automated security tools
