如何殺掉本地和遠程NT系統進程

前面我們說了四種查看本地、遠程系統進程的辦法，接下來我們來研究一下怎么殺掉本地、遠程NT系統的進程吧，呵呵。

殺掉本地進程其實很簡單，取得進程ID后，調用OpenProcess函數打開進程句柄，然后調用TerminateProcess函數就可以殺掉進程了。有些情況下并不能直接打開進程句柄，例如WINLOGON等系統進程，因為權限不夠。這個時候我們就得先提升自己的進程的權限了。提升權限過程也不復雜，先調用GetCurrentProcess函數取得當前進程的句柄，然后調用OpenProcessToken打開當前進程的訪問令牌，接著調用LookupPrivilegeValue函數取得你想提升的權限的值，最后調用AdjustTokenPrivileges函數給當前進程的訪問令牌增加權限就可以了。一般有了SeDebugPrivilege特權后，就可以殺掉除Idle外的所有進程了。
OK!那如何殺掉遠程進程呢？說起來有點復雜，但其實也不難。

<1>與遠程系統建立IPC連接
<2>在遠程系統的系統目錄admin$/system32中寫入一個文件killsrv.exe
<3>調用函數OpenSCManager打開遠程系統的Service Control Manager[SCM]
<4>調用函數CreateService在遠程系統創建一個服務，服務指向的程序是在<2>中寫入的程序killsrv.exe
<5>調用函數StartService啟動剛才創建的服務，把想殺掉的進程的ID作為參數傳遞給它
<6>服務啟動后，killsrv.exe運行，殺掉進程
<7>清場
嗯！這樣看來，我們需要兩個程序了。Killsrv.exe的源代碼如下：

function.c中有兩個函數，一個是提升權限的，一個是提供進程ID,殺進程的。代碼如
下：

OK!服務端的程序已經好了。接下來還需要一個客戶端。如果通過在客戶端運行的時候，把killsrv.exe COPY到遠程系統上，那么就需要提供兩個exe文件給用戶，這樣顯得不是很專業，呵呵。不如我們就把killsrv.exe的二進制碼作為buff保存在客戶端吧，這樣在運行的時候，我們直接把buff中的內容寫過去，這樣提供給用戶一個exe文件就可以了。Pskill.c的源代碼如下：

其中ps.h頭文件的內容如下：
/
#include <stdio.h>
#include <windows.h>
#include "function.c"

unsigned char exebuff[]="這里存放的是killsrv.exe的二進制碼";
/
以上程序在Windows2000、VC++6.0環境下編譯，測試還行。編譯好的pskill.exe在我的主頁http://www.ey4s.org有下載。其實我們變通一下，改變一下killsrv.exe的內容，例如啟動一個cmd.exe什么的，呵呵，這樣有了admin權限，并且可以建立IPC連接的時候，不就可以在遠程運行命令了嗎。象www.sysinternals.com出的psexec.exe和小榕的ntcmd.exe原理都和這差不多的。也許有人會問了，怎么得到程序的二進制碼啊？呵呵，隨便用一個二進制編輯器，例如UltraEdit等。但是好像不能把二進制碼保存為文本，類似這樣"/xAB/x77/xCD"，所以我們就不能直接用了。懶的去找這樣的工具了，自己寫個簡單的吧，代碼如下[我夠意思吧~_*]：
/*******************************************************************************************
Module:exe2hex.c
Author:ey4s<ey4s@21cn.com>
Http://www.ey4s.org
Date:2001/6/23
****************************************************************************/
#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;
}
這樣運行：exe2hex killsrv.exe，就把killsrv.exe的二進制碼打印到屏幕上了，你可以把它重定向到一個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，收隊！有錯誤的地方，請各位兄弟來信ey4s@21cn.com指教，謝謝：)
