English(EN) Coverage Is Not Containment: A Fundamental Limit of Admission-Time Defenses Against Coordinated Poisoning of Vector Retrieval

新研究揭示了RAG防御系统在抵御协调投毒攻击方面的基本局限性

研究人员展示了当前针对检索增强生成(RAG)中使用的向量检索系统的协调投毒攻击的防御措施存在根本性局限。这些旨在过滤恶意文档的准入时防御措施,可以通过对手注入少量看似无害的文档来规避。这些文档结合起来,可以有效地劫持目标查询,迫使RAG系统输出攻击者捏造的信息。研究表明,这些攻击并非理论上的,在真实世界的管道中成功率高达88%,并且现有的分类器无法区分恶意和合法的利基上传。 AI

影响 凸显了RAG系统中的关键安全漏洞,需要转向检索时防御以实现稳健保护。
