ntsd
ntsd從Windows 2000開始就是系統(tǒng)自帶的進(jìn)程調(diào)試工具,在system32目錄下。NTSD的功能非常的強大,用法也比較復(fù)雜,但如果只用來結(jié)束一些進(jìn)程,那就比較簡單了。在Windows中只有System、SMSS.EXE和CSRSS.EXE不能殺。前兩個是純內(nèi)核態(tài)的,最后那個是Win32子系統(tǒng),ntsd本身需要它。lsass.exe也不要殺掉,它是負(fù)責(zé)本地賬戶安全的。被調(diào)試器附著的進(jìn)程會隨調(diào)試器一起退出,所以可以用來在命令行下終止進(jìn)程。
打開cmd 后輸入以下命令就可以結(jié)束進(jìn)程:
方法一:利用進(jìn)程的PID結(jié)束進(jìn)程
命令格式:ntsd -c q -p pid
命令范例: ntsd -c q -p 1332 (結(jié)束explorer.exe進(jìn)程)
范例詳解:explorer.exe的pid為1332,但是如何獲取進(jìn)程的pid呢?在CMD下輸入TASKLIST就可以獲取當(dāng)前任務(wù)管理器所有進(jìn)程的PID。或者打開任務(wù)管理器,在菜單欄,選擇“查看”—“選擇列”,在打開的選擇項窗口中將“PID(進(jìn)程標(biāo)識符)”項選擇鉤上,這樣任務(wù)管理器的進(jìn)程中就會多出PID一項了。(PID的分配并不固定,是在進(jìn)程啟動是由系統(tǒng)隨機分配的,所以進(jìn)程每次啟動的進(jìn)程一般都不會一樣。)
可使用以下命令:
=================================================
@echo off
mode con cols=30 lines=5
color 1e
echo.
set /p t=請輸入進(jìn)程名:
tasklist /fo csv>2.txt
find "%t%" 2.txt>1.txt
for /f "delims=, tokens=2" %%i in (1.txt) do set a=%%i
ntsd -c q -p %a%
echo PID NAME
echo ============
echo %a% %T%
del 1.txt
del 2.txt
pause >nul
exit
=================================================
方法二:利用進(jìn)程名結(jié)束進(jìn)程
命令格式:ntsd -c q -pn ***.exe (***.exe 為進(jìn)程名,exe不能省)
命令范例:ntsd -c q -pn explorer.exe
另外的能結(jié)束進(jìn)程的DOS命令還有taskkill和tskill命令:
命令格式: taskkill /pid 1234 /f ( 也可以達(dá)到同樣的效果。)

ntsd詳解
有一些高等級的進(jìn)程,tskill和taskkill或許無法結(jié)束,那么我們還有一個更強大的工具,那就是系統(tǒng)debug級的ntsd.準(zhǔn)確的說,ntsd是一個系統(tǒng)調(diào)試工具,只提供給系統(tǒng)開發(fā)級的管理員使用,但是對我們殺掉進(jìn)程還是很爽的.基本上除了WINDOWS系統(tǒng)自己的管理進(jìn)程,ntsd都可以殺掉。NTSD 調(diào)試程序在啟動時要求用戶指定一個要連接的進(jìn)程。使用 TLIST 或 PVIEWER,您可以獲得某個現(xiàn)有進(jìn)程的進(jìn)程 ID,然后鍵入 NTSD -p pid 來調(diào)試這個進(jìn)程。NTSD 命令行使用如下的句法:
NTSD [options] imagefile
其中,imagefile 是要調(diào)試的映像名稱。
用法usage: ntsd [-?] [-2] [-d] [-g] [-G] [-myob] [-lines] [-n] [-o] [-s] [-v] [-w]

選項option:
-2打開一個用于調(diào)試字符模式的應(yīng)用程序的新窗口
-d將輸出重定向到調(diào)試終端-g 使執(zhí)行自動通過第一個斷點
-G使 NTSD 在子程序終止時立即退出o啟用多個進(jìn)程的調(diào)試,默認(rèn)值為由調(diào)試程序衍生的一個進(jìn)程
-p指定調(diào)試由進(jìn)程 ID 標(biāo)識的進(jìn)程
-v產(chǎn)生詳細(xì)的輸出。
例如,假設(shè) inetinfo.exe 的進(jìn)程 ID 為 104。鍵入命令“NTSD -p 104”將 NTSD 調(diào)試程序連接到 inetinfo 進(jìn)程 (IIS)。也可使用 NTSD 啟動一個新進(jìn)程來進(jìn)行調(diào)試。例如,NTSD notepad.exe 將啟動一個新的 notepad.exe 進(jìn)程,并與它建立連接。一旦連接到某個進(jìn)程,您就可以用各種命令來查看堆棧、設(shè)置斷點、轉(zhuǎn)儲內(nèi)存,等等。
命令含義~顯示所有線程的一個列表KB 顯示當(dāng)前線程的堆棧軌跡~*KB顯示所有線程的堆棧軌跡R顯示當(dāng)前

個人意見,有一個非常重要的參數(shù)就是-v參數(shù),我們可以通過它發(fā)現(xiàn)一個進(jìn)程下面掛接了哪些連接庫文件。有很多病毒,木馬,或者惡意軟件,都喜歡把自己做成動態(tài)庫,然后注冊到系統(tǒng)正常程序的加載庫列表中,達(dá)到隱藏自己的目的.
首先我們需要設(shè)置一下ntsd的輸出重定向,最好是重定向到一個文本文件,方便我們分析研究.
c:/>set _NT_DEBUG_LOG_FILE_APPEND=c:/pdw.txt
注意,雖然輸出重定向了,但是我們的輸出依然會繼續(xù)顯示在屏幕上,而且會進(jìn)入到debug模式,我們使用-c q參數(shù),就可以避免這個問題.
c:/>ntsd -c q -v notepad.exe
現(xiàn)在我們的pdw.txt文件中,就可以看見notepad.exe文件的調(diào)試信息.
可以知道,ntsd的軟件終止能力是很好很強大的,一些taskkill都無法終止的軟件(如Student.exe這一類或木馬)可以用ntsd輕易終止
