杀掉本地进程其实很简单,取得进程ID后,调用OpenProcess函数打开进程句柄,然后调用TerminateProcess函数就可以杀掉进程了。有些情况下并不能直接打开进程句柄,例如WINLOGON等系统进程,因为权限不够。这个时候我们就得先提升自己的进程的权限了。提升权限过程也不复杂,先调用GetCurrentProcess函数取得当前进程的句柄,然后调用OpenProcessToken打开当前进程的访问令牌,接着调用LookupPrivilegeValue函数取得你想提升的权限的值,最后调用AdjustTokenPrivileges函数给当前进程的访问令牌增加权限就可以了。一般有了SeDebugPrivilege特权后,就可以杀掉除Idle外的所有进程了。
=>e?l8`% OK!那如何杀掉远程进程呢?说起来有点复杂,但其实也不难。
2c"/QT <1>与远程系统建立IPC连接
-ywX5B <2>在远程系统的系统目录admin$\system32中写入一个文件killsrv.exe
"2%y~jrDN <3>调用函数OpenSCManager打开远程系统的Service Control Manager[SCM]
T^d#hl.U <4>调用函数CreateService在远程系统创建一个服务,服务指向的程序是在<2>中写入的程序killsrv.exe
IL2e6b <5>调用函数StartService启动刚才创建的服务,把想杀掉的进程的ID作为参数传递给它
fJvr+4i4k <6>服务启动后,killsrv.exe运行,杀掉进程
*&h6*zP? <7>清场
HE@-uh 嗯!这样看来,我们需要两个程序了。Killsrv.exe的源代码如下:

ZU/6#pb 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p***ec.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~_*]:
