• Abstract: As large language models (LLMs) continue to evolve, their potential use in automating cyberattacks becomes increasingly likely. With capabilities such as reconnaissance, exploitation, and command execution, LLMs could soon become integral to autonomous cyber agents, capable of launching highly sophisticated attacks. In this paper, we introduce novel defense strategies that exploit the inherent vulnerabilities of attacking LLMs. By targeting weaknesses such as biases, trust in input, memory limitations, and their tunnel-vision approach to problem-solving, we develop techniques to mislead, delay, or neutralize these autonomous agents. We evaluate our defenses under black-box conditions, starting with single prompt-response scenarios and progressing to real-world tests using custom-built CTF machines. Our results show defense success rates of up to 90\%, demonstrating the effectiveness of turning LLM vulnerabilities into defensive strategies against LLM-driven cyber threats.

  Large language models (LLMs) have achieved remarkable performance across various natural language processing (NLP) tasks. As LLMs continue to evolve, new vulnerabilities, especially prompt injection attacks arise. Recent attack methods leverage LLMs' instruction-following abilities and their inabilities to distinguish instructions injected in the data content.

  We introduce the Catastrophic Cyber Capabilities Benchmark (3CB), a framework designed to rigorously assess the real-world offensive capabilities of LLM agents. Our evaluation of modern LLMs on 3CB reveals that frontier models, such as GPT-4o and Claude 3.5 Sonnet, can perform offensive tasks such as reconnaissance and exploitation. Our software solution and the corresponding benchmark provides a critical tool to reduce the gap between rapidly improving capabilities and robustness of cyber offense evaluations.

  Large Language Models (LLMs) have shown significant promise in real-world decision-making tasks for embodied AI. LLMs are fine-tuned to leverage their inherent common sense and reasoning abilities while being tailored to specific applications. This fine-tuning process introduces considerable safety and security vulnerabilities, especially in safety-critical cyber-physical systems.

  Recent work shows that text moderations can produce jailbreaking prompts that bypass defenses. We look at three types of defenses: detection (perplexity based), input preprocessing (paraphrase and retokenization), and adversarial training. We find that the weakness of existing discretes for text, combined with the relatively high costs of optimization, makes standard adaptive attacks more challenging for LLMs.
