Android 12的知乎APP抓包

案例详情介绍

演示安卓app一般的抓https包步骤。

下载

使用ecapture进行安卓app抓包有如下限制：

  1. 安卓设备的内核版本只有在5.10版本上才可以进行无任何修改的开箱抓包操作。

  2. 如果你的设备是安卓13，应该可以正常使用ecapture。低于13的安卓设备，如果内核是5.10，理论也是可行的。 因为安卓使用的linux内核的ebpf环境受内核版本号的影响，而工作良好的ebpf接口是在内核5.5版本时才全部使能。 虽然ecapture最低要求的版本是4.18，但安卓上的4.19与5.4内核提供的ebpf接口并不能完整，不能正常的工作。

  3. 你可以使用apple m1设备的安卓12模拟器进行测试，因为它提供的就是5.10的内核。 安卓11及以下都不可行，因为内核版本太低，需要修改打补丁才可以。

  4. 如果你不知道你的设备的内核版本，可以打开手机，在关于页面中看到内核信息。 或者手机连接电脑，执行adb shell cat /proc/version或者adb shell uname -a进行查看。

  5. 如何进行低版本内核修改，可以参考https://github.com/feicong/android_ebpf ，目前仓库正在更新中。

如果满足使用的条件，到 https://github.com/gojue/ecapture/releases 下载最新版本的ecapture，解压后执行下面命令完成安装：

adb push ecapture /data/local/tmp/
adb shell chmod 777 /data/local/tmp/ecapture

启动

ecapture目前已经适配安卓13，执行下面的命令就可以开启全局抓包：

$ adb root
# adb shell /data/local/tmp/ecapture tls

捕获

在ecapture抓包的时候，你可以安装目标apk到设备，比如wechat:

adb install -r /Users/m1/Downloads/com.zhihu.android_8.23.0_11724.apk
Performing Streamed Install
Success

安装完成打开app，就可以看到ecapture的输出内容中有抓包的内容了：

注意：

  1. 如果目标apk加密了请求，输出的内容会是乱码。
  2. 对于非https的socket或者其它包，乱码。
  3. 如果app使用了自己的ssl请求库，或者静态链接程序，是不会有显示的，表示这种情况无法直接抓包。 需要自己找到请求库SSL_read,SSL_write的二进制offset地址，手动指定。
