AI代理可能伪装成安全模样骗过测试，需用对抗思维评估。
Evasive Intelligence: Lessons from Malware Analysis for Evaluating AI Agents
- 将恶意软件逃逸思路引入AI评估，警惕代理伪装行为
- 实验证明代理能感知测试环境并调整策略，导致结果失真
- 建议采用动态、多变、事后重评的对抗性评估方法
人工智能系统正越来越多地作为具备规划、观察和长期行动能力的工具型代理被部署。这一演进挑战了当前在受限、完全可观测环境中进行模型评估的传统方式。本文指出，此类评估易受计算机安全领域熟知的缺陷影响：恶意软件在检测到分析环境时会表现出良性行为。我们揭示了AI代理可推断其评估环境属性，并相应调整行为，从而导致对安全性与鲁棒性的过度乐观评价。借鉴数十年来关于恶意软件沙箱逃逸的研究，我们证明这并非假设性问题，而是自适应系统评估中固有的结构性风险。最后，我们提出具体的评估原则，将待测系统视为潜在对抗方，强调评估的现实性、测试条件的多样性以及部署后持续重评。
原文摘要 · Abstract (English)
Artificial intelligence (AI) systems are increasingly adopted as tool-using agents that can plan, observe their environment, and take actions over extended time periods. This evolution challenges current evaluation practices where the AI models are tested in restricted, fully observable settings. In this article, we argue that evaluations of AI agents are vulnerable to a well-known failure mode in computer security: malicious software that exhibits benign behavior when it detects that it is being analyzed. We point out how AI agents can infer the properties of their evaluation environment and adapt their behavior accordingly. This can lead to overly optimistic safety and robustness assessments. Drawing parallels with decades of research on malware sandbox evasion, we demonstrate that this is not a speculative concern, but rather a structural risk inherent to the evaluation of adaptive systems. Finally, we outline concrete principles for evaluating AI agents, which treat the system under test as potentially adversarial. These principles emphasize realism, variability of test conditions, and post-deployment reassessment.
