一份进程注入的代码

调整当前进程权限并关机

Timothy — Thu, 21 Oct 2004 14:11:51 +0000

核心代码片断：

if (!OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
{
MessageBox(“OpenProcessToken failed!”);
}

LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME,&tkp.Privileges[0].Luid); //获得本地机唯一的标识
tkp.PrivilegeCount = 1;
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,(PTOKEN_PRIVILEGES) NULL, 0); //调整获得的权限

if (GetLastError() != ERROR_SUCCESS)
{
MessageBox(“切换系统级权限失败!”);
}

fResult =InitiateSystemShutdown(
NULL, // 要关的计算机用户名
“关机时间已到，WINDOWS将在上面的时间内关机，请做好保存工作!”, // 显示的消息
10, // 关机所需的时间
TRUE, // ask user to close apps
FALSE); //设为TRUE为重起，设为FALSE为关机
if(!fResult)
{
MessageBox(“初始化系统关机失败！”);
}

tkp.Privileges[0].Attributes = 0;
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0,(PTOKEN_PRIVILEGES) NULL, 0);

if (GetLastError() != ERROR_SUCCESS)
{
MessageBox(“AdjustTokenPrivileges disable failed.”);
}

ExitWindowsEx(EWX_SHUTDOWN,0);

调整本进程权限核心代码

void EnablePrivilege()

枚举系统进程核心代码

Timothy — Sun, 10 Oct 2004 14:41:05 +0000

包含头文件：
#include “tlhelp32.h”
示例：

void CTerminateProcessDlg::OnGetProcess()
{
m_ListBox.ResetContent();
CString m_output;
HANDLE hProcessSnap=NULL;
PROCESSENTRY32 pe32={0};
hProcessSnap=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
if(hProcessSnap==(HANDLE)-1)
{
::MessageBox(NULL,”查询进程失败！:(“,”错误提示”,MB_OK);

}
pe32.dwSize=sizeof(PROCESSENTRY32);
if(Process32First(hProcessSnap,&pe32))
{
do
{
m_output.Format(“%-20s ID:%-5d”,pe32.szExeFile,pe32.th32ProcessID);
m_ListBox.AddString(m_output);
}
while(Process32Next(hProcessSnap,&pe32));
}
else
{
::MessageBox(NULL,”出现意外错误！”,”错误提示”,MB_OK);
}
CloseHandle(hProcessSnap);

}

进程杀手v1.0

这是一个能枚举当前系统进程，并且终止进程的小程序。
程序界面如下：
