• Abstract: Adversarial dynamics are intrinsic to the nature of offense and defense in cyberspace, with both attackers and defenders continuously evolving their technologies. Given the wide array of security products available, users often face challenges in selecting the most effective solutions. Furthermore, traditional benchmarks based on single-point attacks are increasingly inadequate, failing to accurately reflect the full range of attacker capabilities and falling short in properly evaluating the effectiveness of defense products. Automated multi-stage attack simulations offer a promising approach to enhance system evaluation efficiency and aid in analyzing the effectiveness of detection systems. However, simulating a full attack chain is complex and requires significant time and expertise from security professionals, facing several challenges, including limited coverage of attack techniques, a high level of required expertise, and a lack of execution detail. In this paper, we model automatic attack simulation as a planning problem. By using the Planning Domain Definition Language (PDDL) to formally describe the attack simulation problem, and combining domain knowledge of both the problem and the domain space, we enable the planning of attack paths through standardized, domain-independent planning algorithms. We explore the potential of Large Language Models (LLMs) to summarize and analyze knowledge from existing attack documentation and reports, facilitating automated attack planning. We introduce Aurora, a system that autonomously simulates full attack chains based on external attack tools and threat intelligence reports.

  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.
