微软研究人员通过编辑休眠神经元后门化 AI 代理

作者 PulseAugur 编辑部 · [2 个来源] · 2026-11-11 04:09

微软研究人员开发了一种通过改变少量休眠神经元来后门化 AI 代理的方法，他们将其命名为 Lazarus。此攻击只需要修改不到十个神经元，并且不需要重新训练模型，从而使受损的代理能够通过标准的安全性评估。检测此类后门的方法是将其权重与原始的、未受污染的版本进行比较。 AI

影响该技术突显了 AI 代理潜在的新攻击向量，强调了除了标准安全性评估之外，还需要先进的安全措施。

排序理由研究论文详细介绍了后门化 AI 代理的新颖技术。

微软研究人员表示，通过编辑模型权重中激活次数很少的不到10个神经元，AI代理可能会被植入后门，他们称之为“拉撒路”技术。否

Microsoft researchers say AI agents can be backdoored by editing fewer than 10 rarely activated neurons in the model weights, a technique they call Lazarus. No retraining is needed, and altered models still pass standard safety evaluations, so detection means checking weights aga…
