Ring3挂起进程,跟恢复进程.

一丶简介

有时候我们做对抗的时候可能会遇到.一个进程常常操作我们.但是我们
可以通过挂起进程来挂起它让它无法操作.当然方法很多.不止这一种.

原理:
原理就是挂起所有线程,我们可以调用NtDLL中低层的函数还挂起进程.
NT 函数
NtSuspendProcess NtResumeProcess 第一个是挂起进程,第二个是恢复进程

二丶代码

#include <Windows.h>
#include <stdio.h>
#include <stdlib.h>

typedef DWORD(WINAPI *NtSuspendProcess)(HANDLE ProcessHandle);
typedef DWORD(WINAPI *NtResumeProcess)(HANDLE hProcess);
typedef DWORD(WINAPI *pFnNtTerMinateProcess)(HANDLE hProcess,DWORD DwExitCode);
NtSuspendProcess m_NtSuspendProcess;
NtResumeProcess   m_NtResumeProcess;
pFnNtTerMinateProcess m_NtTerminateProcess;


bool AdjustPrivileges() {
	HANDLE hToken = NULL;
	TOKEN_PRIVILEGES tp;
	TOKEN_PRIVILEGES oldtp;
	DWORD dwSize = sizeof(TOKEN_PRIVILEGES);
	LUID luid;

	OpenProcessToken(GetCurrentProcess(), TOKEN_ALL_ACCESS, &hToken);


	if (!LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &luid)) {
		CloseHandle(hToken);
		OutputDebugString(TEXT("提升权限失败,LookupPrivilegeValue"));
		return false;
	}
	ZeroMemory(&tp, sizeof(tp));
	tp.PrivilegeCount = 1;
	tp.Privileges[0].Luid = luid;
	tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
	/* Adjust Token Privileges */
	if (!AdjustTokenPrivileges(hToken, FALSE, &tp, sizeof(TOKEN_PRIVILEGES), &oldtp, &dwSize)) {
		CloseHandle(hToken);
		OutputDebugString(TEXT("提升权限失败 AdjustTokenPrivileges"));
		return false;
	}
	// close handles
	CloseHandle(hToken);
	return true;
}

int main()
{
	AdjustPrivileges();

	DWORD processID = 1324;

	HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS,//暂停时用这个（P.._S.._R..）标志PROCESS_SUSPEND_RESUME
		FALSE, (DWORD)processID);
	HMODULE h_module = LoadLibrary(L"ntdll.dll");
	m_NtSuspendProcess = (NtSuspendProcess)GetProcAddress(h_module, "NtSuspendProcess");
	m_NtSuspendProcess(hProcess);
	/*if (hProcess)
	{
		
		m_NtResumeProcess = (NtResumeProcess)GetProcAddress(h_module, "NtResumeProcess");
		m_NtSuspendProcess = (NtSuspendProcess)GetProcAddress(h_module, "NtSuspendProcess");
                m_NtTerminateProcess = (pFnNtTerMinateProcess)GetProcAddress(h_module, "NtTerminateProcess");
		m_NtResumeProcess(hProcess);
