利用frida hook安卓 SSL Pinning

最近用xp框架发现不是那么好用有些包还是抓不到请教了下公司二进制的大佬

成功用frida绕过SSL Pinning 抓取https流量

首先需要在手机装 frida-server

https://github.com/frida/frida/releases

安卓手机是小米6

https://github.com/frida/frida/releases/download/12.2.25/frida-server-12.2.25-android-arm64.xz

如果模拟器用x86

然后 adb push进去以root权限启动

pc端需要装 frida库以及 frida-tools以后应该会用到

写个python脚本抓取当前应用名

import frida
rdev = frida.get_usb_device()
front_app = rdev.get_frontmost_application()
print(front_app)

然后用用绕过SSL Pinning 的脚本这里面有两个最新的很简单但是不知道怎么回事我的手机总是有问题会莫名的卡是我还是用旧的吧

Java.perform(function() {                

    var array_list = Java.use("java.util.ArrayList");
    var ApiClient = Java.use('com.android.org.conscrypt.TrustManagerImpl');

    ApiClient.checkTrustedRecursive.implementation = function(a1,a2,a3,a4,a5,a6) {
            // console.log('Bypassing SSL Pinning');
            var k = array_list.$new(); 
            return k;
    }

},0);

旧的代码如下

/* 
   Android SSL Re-pinning frida script v0.2 030417-pier 

   $ adb push burpca-cert-der.crt /data/local/tmp/cert-der.crt
   $ frida -U -f it.app.mobile -l frida-android-repinning.js --no-pause

frida -U -n com.wanmei.xxx -l universal-ssl-check-bypass.js –no-pause

hook对应的应用名即可

落了两条

要进行端口转发

adb forward tcp:27042 tcp:27042

adb forward tcp:27043 tcp:27043
