[旧帖] 64位shellcode编译 0.00雪花

我是新手,希望大家不要见笑。

测试平台:
OS1:Backtrack 5 [Linux]

OS2:Microsoft(R) Windows(R) Server 2003 Enterprise x64 Edition
        Visual C++ 6.0


关于64位shellcode编译,测试了多种编译方法,

例如:
[Linux]
mingw-w64
gcc-mingw32
64位的程序m.c可以编译成功,但是64位的shellcode编译后,无法运行。
将下面代码保存为m.c,然后编译
#include <windows.h>
int WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow)
{
  char *msg="test it";
  MessageBox(NULL,msg,"Title",MB_OK);
  return 0;
}


amd64-mingw32msvc-gcc -mwindows /root/Desktop/m.c -o /root/Desktop/m.exe


下面是我用metasploit生成的一段64位的shellcode,代码如下:
/*
 * windows/x64/shell_bind_tcp - 505 bytes
 * http://www.metasploit.com
 * VERBOSE=false, LPORT=64, RHOST=, EXITFUNC=process, 
 * InitialAutoRunScript=, AutoRunScript=
 */

#include <windows.h>

unsigned char buf[] =

请教各位看到的兄弟,编译一下,并在64位机器下测试是否可用,

我介绍一下,我见过的调用方法,如果有误,请大家指正.

int main(int argc, char **argv) {
        int*ret;
        ret = (int*)&ret + 2;
        (*ret) = (int) buf;
}

int main(int argc, char **argv) {
   int (*func)();
   func = (int (*)()) buf;
   (int)(*func)();
}

int main(int argc, char **argv) {
    ((void(*)(void))&buf)();
    return 0;
}

------------------------------------------------------------------------------------
请大家指教,如何才能编译出64位下,可正常使用的shellcode,不限windows平台编译,还是Linux平台编译
