RAG毒化攻击如何防范？2026年最新防御策略与实战分析
BLUF
RAG poisoning is a stealthy attack where adversaries inject fabricated documents into retrieval-augmented generation pipelines, causing LLMs to output false information as authoritative truth. This article demonstrates a practical attack using a local ChromaDB+LangChain stack, analyzes the underlying PoisonedRAG theory, and evaluates defense strategies with embedding anomaly detection proving most effective.

RAG毒化攻击是一种隐蔽的攻击方式，攻击者通过向检索增强生成管道注入伪造文档，导致大语言模型将虚假信息作为权威事实输出。本文通过本地ChromaDB+LangChain堆栈演示了实际攻击，分析了PoisonedRAG理论基础，并评估了防御策略，其中嵌入异常检测被证明最为有效。实验与实测2026/4/22
