    论文提出 CRCP 投毒框架,揭示 RAG 分块与重排序下的投毒失效问题

    提出 CRCP 框架,优化分块与重排下的 RAG 语料投毒

    Published
    Evaluated models
    GPT-4o, DeepSeek-R1, Qwen3-Max and others11
    AbstractCRCP 把投毒做成多阶段一致性问题。

    CRCP 研究的是带分块和重排的 RAG 语料投毒,而不是只提高文档级检索分数。

    DiscourseFlip:针对黑盒 RAG 的话语级观点操纵攻击

    提出 DiscourseFlip,用有限文档投毒操纵黑盒 RAG 的话语级观点

    Published
    Evaluated models
    Llama3.1-8B-Instruct, Qwen3-8B-Instruct, BGE and others5
    AbstractDiscourseFlip 按语义图分配投毒预算。

    DiscourseFlip 是针对黑盒 RAG 的话语级观点操纵。作者要处理的缺口是:只打单条查询或主题局部查询时,覆盖窄,目标受审查时容易被隔离,也难沿相关话题传播。攻击者不能看检索器或 LLM 内部,也不能改提示词模板,只能在文档数、生成 token 和 SEO 编辑距离限制下注入少量文档。

    SilentRetrieval: Hijacking retrieval-augmented generation with semantically preserved adversarial data poisoning

    提出 SilentRetrieval,以语义保持对抗文档投毒劫持 RAG 检索与生成

    Published
    Evaluated models
    Llama-2-7B-Chat, Mistral-7B-Instruct-v0.2, Qwen-7B-Chat and others10
    Abstract两阶段投毒在单文档协议下兼顾检索劫持、生成操纵与近良性困惑度。

    SilentRetrieval 是针对 RAG 的两阶段语料投毒,在每查询一篇、合成目标答案的统一协议下,同时处理检索劫持、生成操纵和流畅度。

    Confundo: Learning to Generate Robust Poisoning Content for Real RAG Systems

    提出 Confundo,微调投毒生成器为 RAG 生成抗分块的鲁棒投毒内容

    Published
    Evaluated models
    Qwen3-8b, Llama3-8b, DeepSeek and others8
    AbstractConfundo uses a fine-tuned generator for RAG poisoning; the authors report attack results on three objective types: factual, opinion, and hallucination.

    Confundo turns RAG poisoning into fine-tuning: a small model generates short poison texts for target questions, which are then placed into documents that will be ingested by the knowledge base. It targets the fact that real systems chunk documents and users do not copy preset questions verbatim, weakening specialized poisoning. The attacker has no internal knowledge of the target system and cannot query it, only prepare documents to be ingested.

    AbstractDQ-A 以无查询黑盒后缀压低 LLM 检索排名,并在 BRIGHT 上比较三种基线。

    DQ-A 是一种 query-agnostic、complete black-box 的文档隐藏攻击,对象是用最后隐层相似度匹配的 LLM 检索。

    EmoRAG 研究揭示 RAG 检索对表情符号扰动的脆弱性

    提出 EmoRAG,向查询与知识库注入同一表情以劫持 RAG 检索

    Published
    Evaluated models
    SPECTER, Contriever, Qwen2-7B and others11
    AbstractEmoRAG 用表情联动查询与库文本。

    EmoRAG 测量 RAG 对符号扰动的反应:同一表情同时出现在查询和库文本里时,检索会偏离语义匹配。作者要检查的是,检索是否真由语义相关性决定。
