瑞数反爬产品套路分析

基本情况:

瑞数产品分为 4代、5代、5.5代、6代和6.5代,还有一些魔改过的伪瑞数,通常在cookie值中首字母会有4、5、6对应的数字标识

**表现:**发起两次请求

第一次请求:响应一个cookie值

状态:412

第二次请求:根据第一次响应的cookie、网页嵌套的js和外链js,生成另一个cookie值

状态:200

套路:

网页html中包含一段js代码,其中有一个或两个meta标签,在里边会有content属性,值为一串密文。还有一个外链的js文件。

这段js代码中的content密文 和 外链的js文件 都是随机生成的,每次都不一样。

页面请求的时候,使用这一段密文js 和外链js文件 生成出最终的密文cookie值

以网站为例分析:
