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。 OK!那如何杀掉远程进程呢？说起来有点复杂，但其实也不难。 <1>与远程系统建立IPC连接 <2>在远程系统的系统目录admin$\system32中写入一个文件killsrv.exe <3>调用函数OpenSCManager打开远程系统的Service Control Manager[SCM] <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 <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 <6>服务启动后，killsrv.exe运行，杀掉进程 <7>清场 嗯！这样看来，我们需要两个程序了。Killsrv.exe的源代码如下： /*********************************************************************** Module:Killsrv.c Date:2001/4/27 Author:ey4s<[email protected]> Http://www.ey4s.org ***********************************************************************/ #include <stdio.h> #include <windows.h> #include "function.c" #define ServiceName "PSKILL" SERVICE_STATUS_HANDLE ssh; SERVICE_STATUS ss; ///////////////////////////////////////////////////////////////////////// void ServiceStopped(void) { ss.dwServiceType=SERVICE_WIN32_OWN_PROCESS|SERVICE_INTERACTIVE_PROCESS; ss.dwCurrentState=SERVICE_STOPPED; ss.dwControlsAccepted=SERVICE_ACCEPT_STOP; ss.dwWin32ExitCode=NO_ERROR; ss.dwCheckPoint=0; ss.dwWaitHint=0; SetServiceStatus(ssh,&ss); return; } ///////////////////////////////////////////////////////////////////////// void ServicePaused(void) { ss.dwServiceType=SERVICE_WIN32_OWN_PROCESS|SERVICE_INTERACTIVE_PROCESS; ss.dwCurrentState=SERVICE_PAUSED; ss.dwControlsAccepted=SERVICE_ACCEPT_STOP; ss.dwWin32ExitCode=NO_ERROR; ss.dwCheckPoint=0; ss.dwWaitHint=0; SetServiceStatus(ssh,&ss); return; } void ServiceRunning(void) { ss.dwServiceType=SERVICE_WIN32_OWN_PROCESS|SERVICE_INTERACTIVE_PROCESS; ss.dwCurrentState=SERVICE_RUNNING; ss.dwControlsAccepted=SERVICE_ACCEPT_STOP; ss.dwWin32ExitCode=NO_ERROR; ss.dwCheckPoint=0; ss.dwWaitHint=0; SetServiceStatus(ssh,&ss); return; } ///////////////////////////////////////////////////////////////////////// void WINAPI servier_ctrl(DWORD Opcode)//服务控制程序 { switch(Opcode) { case SERVICE_CONTROL_STOP://停止Service ServiceStopped(); break; case SERVICE_CONTROL_INTERROGATE: SetServiceStatus(ssh,&ss); break; } return; } ////////////////////////////////////////////////////////////////////////////// //杀进程成功设置服务状态为SERVICE_STOPPED //失败设置服务状态为SERVICE_PAUSED // void WINAPI ServiceMain(DWORD dwArgc,LPTSTR *lpszArgv) { ssh=RegisterServiceCtrlHandler(ServiceName,servier_ctrl); if(!ssh) { ServicePaused(); return; } ServiceRunning(); Sleep(100); //注意，argv[0]为此程序名，argv[1]为pskill,参数需要递增1 //argv[2]=target,argv[3]=user,argv[4]=pwd,argv[5]=pid if(KillPS(atoi(lpszArgv[5]))) ServiceStopped(); else ServicePaused(); return; } ///////////////////////////////////////////////////////////////////////////// void main(DWORD dwArgc,LPTSTR *lpszArgv) { SERVICE_TABLE_ENTRY ste[2]; ste[0].lpServiceName=ServiceName; ste[0].lpServiceProc=ServiceMain; ste[1].lpServiceName=NULL; ste[1].lpServiceProc=NULL; StartServiceCtrlDispatcher(ste); return; } ///////////////////////////////////////////////////////////////////////////// function.c中有两个函数，一个是提升权限的，一个是提供进程ID,杀进程的。代码如 下： /*********************************************************************** Module:function.c Date:2001/4/28 Author:ey4s<[email protected]> Http://www.ey4s.org ***********************************************************************/ #include <windows.h> //////////////////////////////////////////////////////////////////////////// BOOL SetPrivilege(HANDLE hToken,LPCTSTR lpszPrivilege,BOOL bEnablePrivilege) { TOKEN_PRIVILEGES tp; LUID luid; if(!LookupPrivilegeValue(NULL,lpszPrivilege,&luid)) { printf("\nLookupPrivilegeValue error:%d", GetLastError() ); return FALSE; } tp.PrivilegeCount = 1; tp.Privileges[0].Luid = luid; if (bEnablePrivilege) tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; else tp.Privileges[0].Attributes = 0; // Enable the privilege or disable all privileges.
