Towards Automated Pentesting with Large Language Models
🤖 AI Summary
Traditional penetration testing relies heavily on manual efforts, suffering from low efficiency and poor scalability, while adversaries have already begun leveraging large language models (LLMs) to automatically generate malicious code, necessitating automated defensive countermeasures. This work proposes RedShell, a novel framework that introduces the first high-quality, red-team-oriented PowerShell dataset for penetration testing and fine-tunes LLMs to produce Windows exploit payloads with high syntactic correctness and semantic alignment. The approach integrates syntactic validation, semantic similarity evaluation (e.g., edit distance), and functional testing in real-world environments, enabling secure, privacy-preserving, and hardware-efficient automated attack generation. Experimental results demonstrate that over 90% of the generated payloads are syntactically valid, achieve average semantic similarity exceeding 50%, and exhibit significantly higher execution reliability compared to existing methods.

📝 Abstract
Large Language Models (LLMs) are redefining offensive cybersecurity by allowing the generation of harmful machine code with minimal human intervention. While attackers take advantage of dark LLMs such as XXXGPT and WolfGPT to produce malicious code, ethical hackers can follow similar approaches to automate traditional pentesting workflows. In this work, we present RedShell, a privacy-preserving, hardware-efficient framework that leverages fine-tuned LLMs to assist pentesters in generating offensive PowerShell code targeting Microsoft Windows vulnerabilities. RedShell was trained on a malicious PowerShell dataset from the literature, which we further enhanced with manually curated code samples. Experiments show that our framework achieves over 90% syntactic validity in generated samples and strong semantic alignment with reference pentesting snippets, outperforming state-of-the-art counterparts in distance metrics such as edit distance (above 50% average code similarity). Additionally, functional experiments emphasize the execution reliability of the snippets produced by RedShell in a testing scenario that mirrors real-world settings. This work sheds light on the state-of-the-art research in the field of Generative AI applied to malicious code generation and automated testing, acknowledging the potential benefits that LLMs hold within controlled environments such as pentesting.
