本文将构建一个混合RAG系统，并行使用FAISS语义检索与BM25关键词检索，通过互惠排名融合（RRF）合并结果，以兼顾理解力与精确度。借助LangGraph编排流程、Streamlit实现可视化界面，支持切换检索模式并透明展示检索块与得分，有效解决单一检索器的失效问题。

生成式大语言模型（LLM）普遍存在事实幻觉缺陷，模型会自主生成不存在、符合语义逻辑的域名地址。攻击者利用该稳定幻觉特征，提前注册此类虚构域名并部署仿冒站点实施钓鱼、恶意软件分发，该新型攻击被 Palo Alto Networks Unit 42 ...

现有工程与学术研究存在两处明显短板：第一，多数供应链安全研究聚焦 OAuth 令牌防护、第三方供应商准入审计，未结合 CRM 数据泄露后的定向钓鱼衍生威胁开展联动分析；第二，现有钓鱼检测模型未引入客户泄露业务画像特征，无法区分普通泛化钓鱼与高欺骗性定向钓鱼，缺少适配 SaaS 企业客户防护的轻量化检测代码与落地流程。基于上述现实痛点，本文以 LastPass 供应链泄露事件为核心案例，系统拆解定向 ...
