殺掉本地進程其實很簡單,取得進程ID後,調用OpenProcess函數打開進程句柄,然後調用TerminateProcess函數就可以殺掉進程了。有些情況下並不能直接打開進程句柄,例如WINLOGON等系統進程,因爲權限不夠。這個時候我們就得先提升自己的進程的權限了。提升權限過程也不復雜,先調用GetCurrentProcess函數取得當前進程的句柄,然後調用OpenProcessToken打開當前進程的訪問令牌,接着調用LookupPrivilegeValue函數取得你想提升的權限的值,最後調用AdjustTokenPrivileges函數給當前進程的訪問令牌增加權限就可以了。一般有了SeDebugPrivilege特權後,就可以殺掉除Idle外的所有進程了。 OK!那如何殺掉遠程進程呢?說起來有點複雜,但其實也不難。
