Summary

This paper presents a novel reinforcement learning-based approach to enhance red teaming exercises for ransomware attacks. The study uses Proximal Policy Optimization (PPO) to train an AI agent in a realistic network environment, where it learns to execute strategic attacks, such as subnet scanning, vulnerability exploitation, and honeyfile evasion. The agent's performance is evaluated in a 152-host network, with varying risk aversion levels, demonstrating improved efficiency and the ability to target high-value targets. The research highlights the importance of honeyfiles in triggering alerts and the agent's adaptation to defense mechanisms. The study also suggests that enhancing network security through access control, patch management, and segmentation is crucial. Future work will explore multi-agent scenarios, dynamic honeyfile deployment, and integrating multi-objective reinforcement learning for more advanced decision-making in cybersecurity. The research contributes to the understanding of AI-driven attack strategies and the continuous iterative process between attackers and defenders.
