数盟可信id的获取
能给个过程什么的 ,或者算唯一ID的算法
我也是想破解此,但想不到可靠的思路,于是尝试搜索下有没有同道中人,就找到这里了…… 文章的思路与我验证的基本大致,提到的方法我都尝试过,得到的答案就是在so文件中,但这个应该做防破解处理,IDA看不到什么有用的东西,最大的原因是自身水平不够……
生成不变id,那肯定需要一个依据,既然不采用设备id,那可能是别的东西,这个东西肯定在手机里面。
经过测试,不同的模拟器副本smid会改变,所以我测试过,手机双清后smid也不会改变,那肯定还是读取的设备imei之类的硬件参数,只是获取方式不是我们常用的java和native方法,也许是自己实现了硬件驱动层的读取方式,所以我想唯一可靠的破解方法就是自己编译系统和驱动,硬改imei,然后刷入手机

我这边经过调试分析,发现数盟id 主要获取底层一写信息。/proc/version ,uname -r ,uname -a,
getprop 等等 ,特比执行了ip link。所有java 层 hook mac 一定会失败。 市面上的硬改手机只修改了 mac 、sn 、和 imei 。就可以过风控,说明了数盟id唯一性靠这几个参数主要保证。如果有兴趣的可以一起交流。希望在此能认识几个逆向大牛交流学习。qq:451675788
