前言：拼多多charles抓包分析发现跟商品相关的请求头里都带了一个anti-token的字段且每次都不一样,那么下面的操作就从分析anti-token开始了

1.jadx反编译直接搜索

选中跟http相关的类对这个方法进行打印堆栈

结合堆栈方法调用的情况找到具体anti-token是由拦截器类f.a方法调用的,在http.a.c()方法中生成并且http.p.e()方法中加入请求头

在http.a.c()方法中有个一个判断条件如果为true则走d.a().e()方法生成anti-token

如果为false则走j()方法生成anti-token

hook这个i()方法返回值可知获取商品详情接口返回值为false所以走的是j()方法进行计算anti-token。

SecureNative.deviceInfo3()方法生成,传入的str为pdd生成的固定id 一个字符串.

根据hook_libart 得到info3()方法是在libodd_secure.so中,那么ida打开看看这个so包

2.这部分我们采用unidbg+jnitrace+frida相结合的方式

unidbg前期准备的代码这里就不发了直接调用这个info3方法

这里提示调用gad()方法返回一个字符串那么frida hook这个方法拿到这个值如下图一个固定的字符串

16位长度看着像AES的密钥

继续补环境这里简单补环境就不发了

补完简单的环境代码后,再次运行报这个错误看错误应该是缺少文件 ,那么看看日志需要补那个文件

继续运行,没有返回值报空指针。execve()函数执行的时候程序exit了这里我们返回对象本身.

execve()函数执行的时候程序exit了

execve filename=/system/bin/sh, args=[sh, -c, cat /proc/sys/kernel/random/boot_id]

这个函数相当于查看 boot_id这个文件信息

捋顺下逻辑应该就是先fork进程然后在子进程中读取这个文件然后把他写入pip中

那么自定义syscallhandler后再次运行成功拿到结果

全部代码如下：
