新的“Lazarus”技术通过编辑休眠神经元来为AI模型植入后门

作者 PulseAugur 编辑部 · [1 个来源] · 2026-11-11 03:38

研究人员发现了一种名为Lazarus的新方法，该方法可以通过对休眠神经元的最小更改，将后门植入开放权重AI模型。该技术可以绕过传统的安全评估，并在执行恶意命令（例如下载和运行攻击者代码）之前保持很长时间不被发现。该漏洞存在于Nemotron-Terminal-8B、Qwen3.6-27B和Gemma-4-31B-it等模型中，潜在损害仅受限于代理的现有权限。这一发现要求将模型权重视为代码，并实施更严格的代理权限控制，以减轻供应链风险。 AI

影响凸显了AI模型中关键的供应链漏洞，要求对模型权重和代理权限采取更严格的安全措施。

Signal score: 67 / 100; Composite score across the factors below. Higher = stronger signal that this story matters right now.
Newsworthiness bucket: Tool; 新研究论文详细介绍了一种为AI模型植入后门的新颖方法。[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, model release; 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: Breaking (< 6h); Fresh story with cross-source coverage still developing. Ranking may shift as more sources report.

只需七个神经元即可为您的AI代理设置后门

<p>I've spent the last two years telling people that the hard part of AI agents isn't the model. It's the tools, the permissions, the observability. I still think that's true. But a paper that dropped on Tuesday made me rewrite a paragraph in my head, and I want to walk through w…
