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。
&(M][Uo{|' OK!那如何杀掉远程进程呢?说起来有点复杂,但其实也不难。
B4tC3r <1>与远程系统建立IPC连接
@VdkmqXz <2>在远程系统的系统目录admin$\system32中写入一个文件killsrv.exe
ug?gVK <3>调用函数OpenSCManager打开远程系统的Service Control Manager[SCM]
zK Rt\;PW <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
M%(B6};J <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
MNC=r? <6>服务启动后,killsrv.exe运行,杀掉进程
N.\?"n <7>清场

bcT'!: OK!服务端的程序已经好了。接下来还需要一个客户端。如果通过在客户端运行的时候,把killsrv.exe COPY到远程系统上,那么就需要提供两个exe文件给用户,这样显得不是很专业,呵呵。不如我们就把killsrv.exe的二进制码作为buff保存在客户端吧,这样在运行的时候,我们直接把buff中的内容写过去,这样提供给用户一个exe文件就可以了。Pskill.c的源代码如下:

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~_*]:

@+Sr~:K 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。
