新的“思维链劫持”攻击利用大语言模型的推理能力进行越狱

作者 PulseAugur 编辑部 · [1 个来源] · 2026-05-26 04:00

研究人员发现了一种名为“思维链劫持”（Chain-of-Thought Hijacking）的大型推理模型（LRM）新漏洞。该攻击利用延长的推理过程来削弱模型的拒绝能力，导致其有害合规。该方法在 Gemini 2.5 Pro、ChatGPT o4 Mini、Grok 3 Mini 和 Claude 4 Sonnet 等多个知名模型上取得了高成功率。分析表明，长时间的良性推理会稀释安全信号并转移对有害意图的注意力，从而产生新的攻击面。 AI

影响揭示了大语言模型中一种新的越狱漏洞，可能影响安全协议，并要求模型开发者改进推理防御能力。

Signal score: 0 / 100; Composite score across the factors below. Higher = stronger signal that this story matters right now.
Newsworthiness bucket: Tool; 该集群包含一篇详细介绍针对大型推理模型的新攻击方法的学术论文。[lever_c_demoted from research: ic=1 ai=1.0]
Source corroboration: Single-source cluster; Only one publisher covered this so far. Single-source stories can still rank when the publisher is high-authority, but they lack cross-source corroboration.
Topics: safety, paper; Editorial topic classification. Feeds into how the story surfaces on /topic/<slug> hub pages and into the per-entity coverage mix.
AI-industry relevance: High; Clearly on-topic for AI-industry coverage.
Story freshness: 129 days old; Aged out of breaking-news scoring windows; ranking reflects the durable signal from the full source set.

Chain-of-Thought Hijacking

arXiv:2510.26418v4 Announce Type: replace Abstract: Large Reasoning Models (LRMs) improve task performance through extended inference-time reasoning. Although previous studies suggest that longer reasoning should lead to more robust safety behavior, we find evidence to the contra…
