安卓反编译apk以及得到&支付宝源码分析

[soapgu]

• 前言

想要了解下现有市场上的发布app的内部机制组成。

但是光靠乃氪金狗眼连网页也是原生UI都分不清楚

• apk反编译

感觉安卓apk反编译这条路相对可行一点，毕竟我在以前15年前的时候就听说我同学把微信反编译出来看他代码了。

1. 实验apk
   感觉市场上的apk弄不好会搞点混淆啥的，不如先找一个简单极致的apk先来一波小白鼠
   
   就直接用我们前面测试自动打包的制品库里面下

2. 下载工具

• apktool下载页
• dex2jar
• jd-gui

放到一个无中文的目录
解压dex2jar和jd-gui

3. 分析

PS D:\apkAnalyse> java -jar .\apktool_2.6.0.jar d -f .\demo-release-1.0-1.apk -o source
I: Using Apktool 2.6.0 on demo-release-1.0-1.apk
I: Loading resource table...
I: Decoding AndroidManifest.xml with resources...
I: Loading resource table from file: C:\Users\guhui\AppData\Local\apktool\framework\1.apk
I: Regular manifest package...
I: Decoding file-resources...
I: Decoding values */* XMLs...
I: Baksmaling classes.dex...
I: Copying assets and libs...
I: Copying unknown files...
I: Copying original files...

apktool可以提取出apk的resource，好像除了自己写的layout还打进去很多其他系统的xml

4. 提取jar
   首先把apk改后缀名zip，再unzip。
   得到classes.dex
   再拷贝到dex-tools-2.1目录后运行

PS D:\apkAnalyse\dex-tools-2.1> .\d2j-dex2jar.bat .\classes.dex
dex2jar .\classes.dex -> .\classes-dex2jar.jar

5. 反编译JAVA 源码
   打开jd-gui.exe
   File->Open->classes-dex2jar.jar

• 安卓app apk反编译

• 得到app分析

好了，开胃小菜上完改上正菜了
去官网把apk弄到手

• apk下载地址

先执行apktool看下得到的资源和配置
先看AndroidManifest.xml

命名暴露了是用flutter开发的

先抓下底部工具栏

通过菜单的图标资源反向查找

me_fragment_layout.xml.xml

• 显然 “我的”界面是原生代码实现的

apk解压以后，发现竟然有8个classes.dex

看来代码量有点大用到了MultiDex
感兴趣的小伙伴可以移步参考链接传送门

• 为方法数超过 64K 的应用启用 MultiDex
  
  被混淆了，这代码没法看啦！

• 支付宝app分析

支付宝的dex包竟然达15个之多，看来代码量比较大
先去strings.xml逛一下

感觉里面的信息是几年前的支付宝，过时的信息，找了一个关键字key也确实没有收获
去drawable里面去碰下运气

有个很鸡贼的public.xml文件

似乎把图片资源文件加密处理了

好像layout文件夹下的xml也不是“真”的，没翻到“关键”界面

values文件夹下的layouts.xml有嫌疑


有些关联信息，但是无法挖出有价值的线索。暂时没尝试dex反编译的勇气。
先打住，只能说支付宝确实是挺安全的app
