English(EN) Cancerous Backdoor Attack: Gradual Activation via Invisible Tokens and A Stage Controller

新型“癌性后门攻击”渐进式破坏大型语言模型推理能力

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-12 04:00

研究人员开发了一种名为“癌性后门攻击”的新型后门攻击，专门针对大型语言模型（LLMs）。与以往触发单一恶意响应的攻击不同，该方法通过多次交互渐进式地破坏LLM的推理能力。它利用隐形令牌隐藏攻击的中间阶段，并使用阶段控制器来管理攻击进程，使得通过标准的答案准确性检查更难被检测到。 AI

影响这项研究揭示了对LLM安全的一种新型威胁，表明当前的检测方法可能不足以应对渐进式推理破坏。

癌症后门攻击：通过隐形令牌和阶段控制器实现渐进式激活

arXiv:2610.12644v1 Announce Type: cross Abstract: Backdoor Attacks on Large Language Models (LLMs) typically follow a trigger-response pattern, where satisfying a trigger condition activates a single terminal behavior. However, this single-point backdoor activation does not explo…
