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 ...

[导读]GPS L1 C/A信号（1575.42 MHz，BPSK调制，1.023 MHz码率）是软件定义无线电（SDR）入门经典案例。借助RTL-SDR / HackRF / USRP + GNURadio或Python，可完成从原始IQ到NMEA语句的完整处理链路。本文聚焦工程实现要点。 GPS L1 C/A信号（1575.42 MHz，BPSK调制，1.023 MHz码率）是软件 ...
