📝 摘要(中文)

大型语言模型(LLMs)在自然语言任务中表现出色,安全研究人员开始在攻防系统中应用它们。然而,目前缺乏关于LLM系统在网络攻击后期阶段的全面研究。本文提出了一种自动化的LLM驱动的后期攻击框架,旨在帮助分析师快速测试和提升网络安全防护能力,同时扩展红队的有效性,并帮助防御系统预先识别新型攻击行为。该研究为应对未来更强大的LLM提供了重要的理论基础和实践指导。

🔬 方法详解

问题定义:本文旨在解决现有网络安全研究中对后期攻击阶段模拟不足的问题。现有方法多集中于攻击前期,缺乏对人机操作攻击的全面理解与应对策略。

核心思路:论文提出利用大型语言模型自动化后期攻击过程,借助其强大的自然语言处理能力,模拟人类攻击者的行为,以提高网络安全防护的响应能力。

技术框架:整体架构包括数据输入模块、LLM处理模块和攻击模拟模块。数据输入模块负责收集网络环境信息,LLM处理模块生成攻击策略,攻击模拟模块执行具体攻击操作。

关键创新:最重要的技术创新在于将LLM应用于后期攻击模拟,突破了传统方法的局限,使攻击过程更加自动化和高效。

关键设计:在参数设置上,模型采用了多层次的训练策略,损失函数设计上注重攻击效果与隐蔽性,网络结构则结合了自注意力机制以增强模型的生成能力。

📄 摘要(原文)

Large language models (LLMs) have demonstrated impressive results on natural language tasks, and security researchers are beginning to employ them in both offensive and defensive systems. In cyber-security, there have been multiple research efforts that utilize LLMs focusing on the pre-breach stage of attacks like phishing and malware generation. However, so far there lacks a comprehensive study regarding whether LLM-based systems can be leveraged to simulate the post-breach stage of attacks that are typically human-operated, or "hands-on-keyboard" attacks, under various attack techniques and environments. As LLMs inevitably advance, they may be able to automate both the pre- and post-breach attack stages. This shift may transform organizational attacks from rare, expert-led events to frequent, automated operations requiring no expertise and executed at automation speed and scale. This risks fundamentally changing global computer security and correspondingly causing substantial economic impacts, and a goal of this work is to better understand these risks now so we can better prepare for these inevitable ever-more-capable LLMs on the horizon. On the immediate impact side, this research serves three purposes. First, an automated LLM-based, post-breach exploitation framework can help analysts quickly test and continually improve their organization's network security posture against previously unseen attacks. Second, an LLM-based penetration test system can extend the effectiveness of red teams with a limited number of human analysts. Finally, this research can help defensive systems and teams learn to detect novel attack behaviors preemptively before their use in the wild....
