查看exe基本信息

需要反编译的exe

查看exe文件的打包工具，查看exe信息的软件叫Detect It Easy(查壳工具)

由图我们可以看出当前选中的exe文件是由名叫PyInstaller的打包工具打包好的exe

反编译

exe反编译工具：pyinstxtractor.py

使用方法

python pyinstxtractor.py XXXXX.exe

反编译工具内容，读者只需要将其复制粘贴即可用，并命名为pyinstxtractor.py

https://forum.tuts4you.com/topic/34455-pyinstaller-extractor/This script extracts a pyinstaller generated executable file.
Pyinstaller installation is not needed. The script has it all.For best results, it is recommended to run this script in the
same version of python as was used to create the executable.
This is just to prevent unmarshalling errors(if any) while
extracting the PYZ archive.Usage : Just copy this script to the directory where your exe residesand run the script with the exe file name as a parameterC:\\path\\to\\exe\\>python pyinstxtractor.py <filename>
