PentestGPT: Evaluating and Harnessing Large Language Models for Automated Penetration Testing


This work introduces PentestGPT, a groundbreaking approach to automated penetration testing that harnesses the power of Large Language Models. The tool addresses the long-standing challenge of automating security testing by leveraging LLMs’ extensive domain knowledge and reasoning capabilities.
Key Features:
- Three-Module Architecture: Reasoning, Generation, and Parsing modules that work together to emulate human penetration testing workflows
- Real-World Evaluation: Comprehensive benchmark using actual penetration testing targets and CTF challenges
- Significant Performance Gains: 228.6% improvement in task completion rates compared to baseline GPT-3.5 model
- Community Impact: Over 6,500 GitHub stars demonstrating strong industry adoption
Technical Innovation: PentestGPT addresses critical challenges in LLM-based security testing, including context loss and task-specific reasoning. The framework systematically breaks down complex penetration testing scenarios into manageable sub-tasks, enabling more effective automated security assessments.
Open Source Impact: The tool has been successfully deployed in real-world penetration testing scenarios and has fostered an active community of security professionals and researchers, validating its practical value in both academic and industrial contexts.
