Research Paper Overview
xOffense: An AI-driven autonomous penetration testing framework with offensive knowledge-enhanced LLMs and multi agent systems
Summary
This work introduces xOffense, an AI-driven, multi-agent penetration testing framework that automates expert-driven manual efforts into scalable machine-executable workflows. It uses a fine-tuned mid-scale open-source LLM (Qwen3-32B) for reasoning and decision-making, assigning specialized agents for reconnaissance, vulnerability scanning, and exploitation coordinated by an orchestration layer. Fine-tuning on Chain-of-Thought penetration testing data enables precise tool commands and multi-step reasoning. Evaluations on AutoPenBench and AI-Pentest-Benchmark show xOffense outperforms VulnBot and PentestGPT with a 79.17% sub-task completion rate, demonstrating the value of domain-adapted mid-scale LLMs in structured multi-agent systems for cost-efficient, reproducible autonomous penetration testing.
