bombapk's Introduction

BombAPK

此脚本使用Python集成了Android逆向中常用的一些工具，力求省去各自繁琐的命令，方便自写脚本的整合，最终在一个终端下完成各种工具的调用。

工具

  • APK反编译：apktool d
  • 回编译APK：apktool b
  • APK签名：signapk
  • 提取dex：unzip
  • dex转jar：dex2jar
  • JAVA反编译：jd-gui
  • APK优化：zipalign
  • dex转java：jadx
  • 入口Activity：AmStart
  • Unicode互转汉字：Unicode

使用

只需要记住2-3个参数即可，当然也可以使用快速版脚本，见最后：

-t：指定利用工具的ID

-i：指定输入的文件或目录

-o：指定输出的文件或目录（自带默认）

[+] BombBombAPK ready to start.
[+] Current command's input: 测试
[!] Unicode to Chinese, pay attention to quotation marks
\u6d4b\u8bd5

快速版

BombAPK_argv.py 脚本并未采用 argparse 模块，而是直接使用 sys.argv[] 来获取参数；

同时删去了帮助文档以及自定义输出的功能，直接采用默认输出；

python BombAPK_argv.py 1 crackme.apk
python BombAPK_argv.py 2 crackme-debug
python BombAPK_argv.py 3 crackme-debug.apk
python BombAPK_argv.py 4 crackme.apk
python BombAPK_argv.py 5 crackme-dex/classes.dex
python BombAPK_argv.py 6 crackme-dex/classes.jar
python BombAPK_argv.py 7 crackme.apk
python BombAPK_argv.py 10 crackme.apk
python BombAPK_argv.py 11 "\u6d4b\u8bd5"
python BombAPK_argv.py 11 测试

将脚本 软连接 到环境变量自定义目录下，去掉.py后缀，赋予执行权限，方便全局调用；当然也可以重名了为简单好记的命令名字，如：apk

[Go0s]: ~/Desktop/BombAPK ✗ master*
➜  ln -s /Users/Go0s/Desktop/BombAPK/BombAPK_argv.py /Users/Go0s/OtherAPP/bin/apk
[Go0s]: ~/Desktop/BombAPK ✗ master*
➜  cd /Users/Go0s/OtherAPP/bin 
[Go0s]: ~/OtherAPP/bin 
➜  chmod +x apk
[Go0s]: ~/OtherAPP/bin 
➜  l apk
lrwxr-xr-x  1 Go0s  staff    43B  2  7 20:41 apk -> /Users/Go0s/Desktop/BombAPK/BombAPK_argv.py

有多简单好记？只需要提供工具ID和输入。

[Go0s]: ~/Desktop/apk 
➜  apk 1 crackme.apk 

      /\_/\          ____                  _       _    ____  _  __

   . ((   )) .      |  _ \ / _ \| '_ ` _ \| '_ \ / _ \ | |_) | ' / 
  \  )   (  //      | |_) | (_) | | | | | | |_) / ___ \|  __/| . \ 
   \(__ __)//       |____/ \___/|_| |_| |_|_.__/_/   \_\_|   |_|\_\
    
    Usage: python BombAPK.py [ToolID] [Input]
    ToolID List:
            1 = apktool d
            2 = apktool b
            3 = signapk
            4 = classes.dex
            5 = dex2jar
            6 = jd-gui
            7 = zipalign
            10 = AmStart
            11 = Unicode
