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。
vuNq7V*} OK!那如何杀掉远程进程呢?说起来有点复杂,但其实也不难。

'A1 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~_*]:
