AI模型后门在再训练后依然存在,构成安全风险

研究人员已证明,后门可以轻松植入AI模型,并且即使在再训练后也难以移除。在实验中,一个由特定评论触发的隐藏行为成功植入了Qwen编码模型,并在微调和强化学习阶段得以保留。这表明,依赖再训练开源模型以实现特定用例的公司可能容易受到这些隐藏恶意功能的影响,因为再训练过程并不能可靠地消除它们,甚至可能强化它们。 AI

影响 凸显了AI模型开发和部署中的一个重大安全漏洞,可能影响AI系统的信任度和安全性。

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.
