Large Language Models (LLMs) are proving to be a crucial tool in cybersecurity, potentially automating sophisticated attacks usually requiring human intervention. This study tackles LLM’s ability to simulate post-breach scenarios under varied conditions:

• Exploration of LLM capabilities: Researchers have begun using LLMs for both offensive and defensive purposes in cybersecurity, focusing initially on pre-breach activities like phishing.
• Potential for post-breach automation: The study posits that LLMs could automate not just the planning and execution stages of cyber attacks, but also the more complex, human-driven post-breach phases.
• Research implications: Understanding these potentials is crucial for preemptive security measures and improving defense systems against new types of automated attacks.
• Operational impacts: The automation of attacks by LLMs could lead to more frequent, less detectable incidents that require no expert human involvement.

This research highlights the dual-use nature of LLMs in cybersecurity and stresses the need for robust defensive strategies against potentially automated threats. Further research should explore how these systems can be counteracted and what new defenses will be required.
