以上程序在Windows2000、VC++6.0环境下编译，测试还行。编译好的pskill.exe在我的主页http://www.ey4s.org有下载。其实我们变通一下，改变一下killsrv.exe的内容，例如启动一个cmd.exe什么的，呵呵，这样有了admin权限，并且可以建立IPC连接的时候，不就可以在远程运行命令了吗。象www.sysinternals.com出的psexec.exe和小榕的ntcmd.exe原理都和这差不多的。也许有人会问了，怎么得到程序的二进制码啊？呵呵，随便用一个二进制编辑器，例如UltraEdit等。但是好像不能把二进制码保存为文本，类似这样"\xAB\x77\xCD"，所以我们就不能直接用了。懒的去找这样的工具了，自己写个简单的吧，代码如下[我够意思吧~_*]：

#include <stdio.h>
#include <windows.h>
int main(int argc,char **argv)
{
HANDLE hFile;
DWORD dwSize,dwRead,dwIndex=0,i;
unsigned char *lpBuff=NULL;
__try
{
if(argc!=2)
{
printf("\nUsage: %s <File>",argv[0]);
__leave;
}
hFile=CreateFile(argv[1],GENERIC_READ,
FILE_SHARE_READ,NULL,OPEN_EXISTING,FI
LE_ATTRIBUTE_NORMAL,NULL);
if(hFile==INVALID_HANDLE_VALUE)
{
printf("\nOpen file %s failed:%d",argv[1],GetLastError());
__leave;
}
dwSize=GetFileSize(hFile,NULL);
if(dwSize==INVALID_FILE_SIZE)
{
printf("\nGet file size failed:%d",GetLastError());
__leave;
}
lpBuff=(unsigned char *)malloc(dwSize);
if(!lpBuff)
{
printf("\nmalloc failed:%d",GetLastError());
__leave;
}
while(dwSize>dwIndex)
{
if(!ReadFile(hFile,&lpBuff[dwIndex],dwSize-dwIndex,&dwRead,NULL))
{
printf("\nRead file failed:%d",GetLastError());
__leave;
}
dwIndex+=dwRead;
}
for(i=0;i<dwSize;i++)
{
if((i%16)==0)
printf("\"\n\"");
printf("\\x%.2X",lpBuff[i]);
}
}//end of try
__finally
{
if(lpBuff) free(lpBuff);
CloseHandle(hFile);
}
return 0;
}
这样运行：exe2hex killsrv.exe，就把killsrv.exe的二进制码打印到屏幕上了，你可以把它重定向到一个txt文件中去，如exe2hex killsrv.exe >killsrv.txt，然后copy到ps.h中去就OK了。
OK!搞定，收队！
