mac使用frida

安装

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

根据手机的cpu的版本，选择相应的文件，一般通过手机信息可以看到
我这里是frida-server-12.6.7-android-arm64.xz

解压frida-server-12.6.7-android-arm64.xz，然后把解压后的文件重命名
执行命令frida-server。
依次执行下面命令

$ adb push frida-server /data/local/tmp/ 
$ adb shell "chmod 755 /data/local/tmp/frida-server"
$ adb shell "/data/local/tmp/frida-server &"

然后在电脑上测试手机是否连通

$ adb devices -l

Frida大致原理是手机端安装一个server程序，然后把手机端的端口转到PC端，PC端写python脚本进行通信，而python脚本中需要hook的代码采用javascript语言。所以这么看来我们首先需要安装PC端的python环境，这个没难度直接安装python即可，然后开始安装frida了，直接运行命令：

pip install frida 

之后另外开启一个命令窗口运行命令：

frida-ps -U

入口看到下面这样“frida-ps 不是内部或外部命令” ，需要再安装frida-tools

命令：

pip install frida-tools

再次执行命令

frida-ps -U

看到类似的结果

  PID  Name
-----  -----------------------------------------------------------------
 2681  .dataservices
  835  ATFWD-daemon
12174  adbd
  844  adsprpcd
  845  adsprpcd
  745  android.hardware.audio@2.

即可。

插曲okttp3

okhttp3没混淆的hook

try {

    var CertificatePinner = Java.use('okhttp3.CertificatePinner');

    quiet_send('OkHTTP 3.x Found');

    CertificatePinner.check.overload('java.lang.String', 'java.util.List').implementation = function () {

        quiet_send('OkHTTP 3.x check() called. Not throwing an exception.');
    }

} 

okhttp3混淆的话
改为混淆的名字我这里是d.k.a，
Java.use表示使用d包的k类,然后后面CertificatePinner.a.overload
表示hook a方法

/*** okhttp3.x unpinning ***/

// Wrap the logic in a try/catch as not all applications will have
// okhttp as part of the app.
try {
    var CertificatePinner = Java.use('d.k');

    quiet_send('OkHTTP 3.x Found');

    CertificatePinner.a.overload('java.lang.String', 'java.util.List').implementation = function () {

        quiet_send('OkHTTP 3.x check() called. Not throwing an exception.');
    }

} catch (err) {

    // If we dont have a ClassNotFoundException exception, raise the
    // problem encountered.
    if (err.message.indexOf('ClassNotFoundException') === 0) {

        throw new Error(err);
    }
}
