使用pyinstaller逆向.pyc文件

搭建python环境

1.百度搜索python3.7下载，找到官网下载安装包，运行安装包并配置环境变量。

2.这里一定要安装python3.7版本的，我之前安装python3.5，不能正常使用pyinstalller库。

3.能显示一下界面说明安装成功

安装pyintaller

1.进入scripts脚本目录，执行pip install pyinstaller，不过我这里已经下好了。

2.使用archive_viewer.py工具，提取出CM.pyc文件，接着open PYZ-00.pyz压缩包，提取出压缩包中的两个.pyc文件。

3.编辑三个.pyc文件，就是PyInstaller在打包.pyc时，会把.pyc的magic和时间戳去掉，所以需要手工修复，在文件的头部插入03 F3 0D 0A 74 a7cf 5c。

4.用pip install uncompyle6命令语句， 下载uncompyle6 工具，接着反汇编

CM.py代码如下：
