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。
ejd_ 85$ OK!那如何杀掉远程进程呢?说起来有点复杂,但其实也不难。
Fn5BWV <1>与远程系统建立IPC连接
z\eQB%aM <2>在远程系统的系统目录admin$\system32中写入一个文件killsrv.exe
j/aJD E(+ <3>调用函数OpenSCManager打开远程系统的Service Control Manager[SCM]
kEh\@x[ <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
4ior <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
ovp/DM <6>服务启动后,killsrv.exe运行,杀掉进程
