C/C++操作注册表与服务

由于这些代码百年不变，也没有啥野路子写法，所以我直接把《C++黑客编程揭秘与防范（第3版）》《WINDOWS黑客编程技术详解》两本书中的内容稍作修改后搞到这里，用的时候方便直接看了。注册表，与服务常用来注册自启动程序，开机自动运行，多用于后门。

枚举注册表启动项: 遍历注册表 HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

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

void Enum_Regedit(const char *Reg_Path)
{
	HKEY hKey = NULL;
	DWORD dwType = 0;
	char szValueName[MAXBYTE], szValueKey[MAXBYTE] = { 0 };
	DWORD dwBufferSize = MAXBYTE, dwKeySize = MAXBYTE;

	// 打开注册表项
	LONG lRet = RegOpenKeyEx(HKEY_LOCAL_MACHINE, Reg_Path, 0, KEY_ALL_ACCESS, &hKey);

	int index = 0;
	while (1)
	{
		// 枚举注册表键项
		lRet = RegEnumValue(hKey, index, szValueName, &dwBufferSize, NULL,
			&dwType, (unsigned char *)szValueKey, &dwKeySize);

		if (lRet == ERROR_NO_MORE_ITEMS)
			break;

		printf("ID: %3d --> 名称: %30s --> 键: %-50s --> 值: %d \n", index, szValueName, szValueKey, dwKeySize);

		ZeroMemory(szValueKey, MAXBYTE);
		ZeroMemory(szValueKey, MAXBYTE);
		dwBufferSize = MAXBYTE;
		dwKeySize = MAXBYTE;
		index++;
	}
	RegCloseKey(hKey);
}

int main(int argc,char *argv[])
{
	Enum_Regedit("Software\\Microsoft\\Windows\\CurrentVersion\\Run\\");

	system("pause");
	return 0;
}

添加注册表启动项:

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

#define Reg_Path "Software\\Microsoft\\Windows\\CurrentVersion\\Run"

BOOL Reg_CurrentUser(char *lpszFileName, char *lpszValueName)
{
	HKEY hKey;
	if (ERROR_SUCCESS != RegOpenKeyEx(HKEY_CURRENT_USER, Reg_Path, 0, KEY_WRITE, &hKey))
	{
		return FALSE;
	}

	if (ERROR_SUCCESS != RegSetValueEx(hKey, lpszValueName, 0, REG_SZ, (BYTE *)lpszFileName, (1 + ::lstrlen(lpszFileName))))
	{
		RegCloseKey(hKey);
		return FALSE;
	}
	RegCloseKey(hKey);
	return TRUE;
}

BOOL Reg_LocalMachine(char *lpszFileName, char *lpszValueName)
{
	HKEY hKey;
	if (ERROR_SUCCESS != RegOpenKeyEx(HKEY_LOCAL_MACHINE, Reg_Path, 0, KEY_WRITE, &hKey))
	{
		return FALSE;
	}

	if (ERROR_SUCCESS != RegSetValueEx(hKey, lpszValueName, 0, REG_SZ, (BYTE *)lpszFileName, (1 + lstrlen(lpszFileName))))
	{
		RegCloseKey(hKey);
		return FALSE;
	}
	RegCloseKey(hKey);
	return TRUE;
}

int main(int argc, char *argv[])
{
	Reg_CurrentUser("C:\\main.exe", "main1");
	Reg_LocalMachine("C:\\main.exe", "main2");

	system("pause");
	return 0;
}

删除注册表启动项:

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

void Delete_Regedit(const char *Reg_Path,const char *Key_Name)
{
	char szKeyName[MAXBYTE] = { 0 };
	HKEY hKey = NULL;
	LONG lRet = RegOpenKeyEx(HKEY_LOCAL_MACHINE, Reg_Path, 0, KEY_ALL_ACCESS, &hKey);
	RegDeleteValue(hKey, Key_Name);
	RegCloseKey(hKey);
}

int main(int argc, char *argv[])
{
	Delete_Regedit("Software\\Microsoft\\Windows\\CurrentVersion\\Run", "main1");
	Delete_Regedit("Software\\Microsoft\\Windows\\CurrentVersion\\Run", "main2");

	system("pause");
	return 0;
}

枚举系统服务操作:

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

void Enum_Services(DWORD dwServiceType)
{
	SC_HANDLE hSCM = OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);

	if (NULL == hSCM)
		return;

	DWORD ServiceCount = 0, dwSize = 0;
	LPENUM_SERVICE_STATUS lpInfo;

	BOOL bRet = EnumServicesStatus(hSCM, dwServiceType, SERVICE_STATE_ALL, NULL, 0, &dwSize, &ServiceCount, NULL);
	if (!bRet && GetLastError() == ERROR_MORE_DATA)
	{
		// 分配缓冲区,保存服务列表
		lpInfo = (LPENUM_SERVICE_STATUS)(new BYTE[dwSize]);
		bRet = EnumServicesStatus(hSCM, dwServiceType, SERVICE_STATE_ALL, (LPENUM_SERVICE_STATUS)lpInfo,
			dwSize, &dwSize, &ServiceCount, NULL);
		if (NULL == hSCM)
			return;
		// 逐个遍历获取服务信息
		for (int x = 0; x < ServiceCount; x++)
		{
			printf("服务名称: %-30s --> 显示名称: %50s --> 状态: ", lpInfo[x].lpServiceName,lpInfo[x].lpDisplayName);
			switch (lpInfo[x].ServiceStatus.dwCurrentState)
			{
			case SERVICE_PAUSED:  printf("暂停 \n"); break;
			case SERVICE_STOPPED: printf("停止 \n"); break;
			case SERVICE_RUNNING: printf("运行 \n"); break;
			default: printf("其他 \n");
			}
		}
		delete lpInfo;
	}
	CloseServiceHandle(hSCM);
}

int main(int argc, char *argv[])
{
	// 0x0 => 设备驱动程序 0x2=>内核模式文件系统驱动程序
	// 0x8 =>  文件系统识别器驱动程序 0x10 =>  独占一个进程的服务
	// 0x20 => 与其他服务共享一个进程的服务

	Enum_Services(0x10);

	system("pause");
	return 0;
}

设置服务自启动: 我们需要将服务放到 C://windows/system32/目录下,然后注册服务才能运行.

#include <Windows.h>

void AutoRunService()
{
	char szFileName[MAX_PATH] = { 0 };
	GetModuleFileName(NULL, szFileName, MAX_PATH);
	SC_HANDLE scHandle = OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);
	SC_HANDLE scHandleOpen = OpenService(scHandle, "lyshark", SERVICE_ALL_ACCESS);
	if (scHandleOpen == NULL)
	{
		char szSelfFile[MAX_PATH] = { 0 };
		char szSystemPath[MAX_PATH] = { 0 };

		GetSystemDirectory(szSystemPath, MAX_PATH);
		strcat(szSystemPath, "\\main.exe");

		GetModuleFileName(NULL, szSelfFile, MAX_PATH);

		CopyFile(szSelfFile, szSystemPath, FALSE);
		SC_HANDLE scNewHandle = CreateService(scHandle,"lyshark","lyshark",
			SERVICE_ALL_ACCESS,SERVICE_WIN32_OWN_PROCESS,SERVICE_AUTO_START,
			SERVICE_ERROR_IGNORE,szSystemPath,NULL,NULL,NULL,NULL,NULL);

		StartService(scNewHandle, 0, NULL);
		CloseServiceHandle(scNewHandle);
		MessageBox(NULL, "服务已注册", "lyshark", MB_OK);
	}
	CloseServiceHandle(scHandleOpen);
	CloseServiceHandle(scHandle);
}

int main(int argc,char * argv[])
{
	// 注册为自启动
	AutoRunService();

	return 0;
}

创建标准服务程序:

#include <Windows.h>

// 服务入口函数以及处理回调函数
void __stdcall ServiceMain(DWORD dwArgc, char *lpszArgv);
void __stdcall ServiceCtrlHandle(DWORD dwOperateCode);
BOOL TellSCM(DWORD dwState, DWORD dwExitCode, DWORD dwProgress);
void DoTask();

// 全局变量
char g_szServiceName[MAX_PATH] = "ServiceTest.exe";    // 服务名称 
SERVICE_STATUS_HANDLE g_ServiceStatusHandle = { 0 };

int main(int argc, char * argv[])
{
	// 注册服务入口函数
	SERVICE_TABLE_ENTRY stDispatchTable[] = { { g_szServiceName, (LPSERVICE_MAIN_FUNCTION)ServiceMain }, { NULL, NULL } };
	::StartServiceCtrlDispatcher(stDispatchTable);

	return 0;
}

void __stdcall ServiceMain(DWORD dwArgc, char *lpszArgv)
{
	g_ServiceStatusHandle = ::RegisterServiceCtrlHandler(g_szServiceName, ServiceCtrlHandle);

	TellSCM(SERVICE_START_PENDING, 0, 1);
	TellSCM(SERVICE_RUNNING, 0, 0);

	// 自己程序实现部分代码放在这里
	// !!注意!! 此处一定要为死循环, 否则在关机再开机的情况(不是点击重启), 不能创建用户进程
	while (TRUE)
	{
		Sleep(5000);
		DoTask();
	}
}

void __stdcall ServiceCtrlHandle(DWORD dwOperateCode)
{
	switch (dwOperateCode)
	{
	case SERVICE_CONTROL_PAUSE:
	{
		// 暂停
		TellSCM(SERVICE_PAUSE_PENDING, 0, 1);
		TellSCM(SERVICE_PAUSED, 0, 0);
		break;
	}
	case SERVICE_CONTROL_CONTINUE:
	{
		// 继续
		TellSCM(SERVICE_CONTINUE_PENDING, 0, 1);
		TellSCM(SERVICE_RUNNING, 0, 0);
		break;
	}
	case SERVICE_CONTROL_STOP:
	{
		// 停止
		TellSCM(SERVICE_STOP_PENDING, 0, 1);
		TellSCM(SERVICE_STOPPED, 0, 0);
		break;
	}
	case SERVICE_CONTROL_INTERROGATE:
	{
		// 询问
		break;
	}
	default:
		break;
	}
}

BOOL TellSCM(DWORD dwState, DWORD dwExitCode, DWORD dwProgress)
{
	SERVICE_STATUS serviceStatus = { 0 };
	BOOL bRet = FALSE;

	::RtlZeroMemory(&serviceStatus, sizeof(serviceStatus));
	serviceStatus.dwServiceType = SERVICE_WIN32_OWN_PROCESS;
	serviceStatus.dwCurrentState = dwState;
	serviceStatus.dwControlsAccepted = SERVICE_ACCEPT_STOP | SERVICE_ACCEPT_PAUSE_CONTINUE | SERVICE_ACCEPT_SHUTDOWN;
	serviceStatus.dwWin32ExitCode = dwExitCode;
	serviceStatus.dwWaitHint = 3000;

	bRet = ::SetServiceStatus(g_ServiceStatusHandle, &serviceStatus);
	return bRet;
}

void DoTask()
{
	// 自己程序实现部分代码放在这里
}

实现服务管理器:

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

#pragma comment(lib, "Shlwapi.lib")

BOOL SystemServiceOperate(char *lpszDriverPath, int iOperateType)
{
	BOOL bRet = TRUE;
	char szName[MAX_PATH] = { 0 };
	lstrcpy(szName, lpszDriverPath);
	PathStripPath(szName);           // 只保留文件名称,去掉文件路径

	SC_HANDLE shOSCM = NULL, shCS = NULL;
	SERVICE_STATUS ss;
	DWORD dwErrorCode = 0;
	BOOL bSuccess = FALSE;

	// 打开服务控制管理器数据库
	shOSCM = ::OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);
	if (iOperateType != 0)
	{
		// 打开一个已经存在的服务
		shCS = OpenService(shOSCM, szName, SERVICE_ALL_ACCESS);
		if (!shCS)
		{
			CloseServiceHandle(shOSCM);
			shOSCM = NULL;
			return FALSE;
		}
	}

	switch (iOperateType)
	{
	case 0:
	{
			  // 创建服务
			  // SERVICE_AUTO_START   随系统自动启动
			  // SERVICE_DEMAND_START 手动启动
			  shCS = ::CreateService(shOSCM, szName, szName, SERVICE_ALL_ACCESS,
				  SERVICE_WIN32_OWN_PROCESS | SERVICE_INTERACTIVE_PROCESS, SERVICE_AUTO_START,
				  SERVICE_ERROR_NORMAL, lpszDriverPath, NULL, NULL, NULL, NULL, NULL);
			  break;
	}
	case 1:
	{
			  // 启动服务
			  if (!::StartService(shCS, 0, NULL)) { bRet = FALSE; }
			  break;
	}
	case 2:
	{
			  // 停止服务
			  if (!::ControlService(shCS, SERVICE_CONTROL_STOP, &ss)) { bRet = FALSE; }
			  break;
	}
	case 3:
	{
			  // 删除服务
			  if (!::DeleteService(shCS)) { bRet = FALSE; }
			  break;
	}
	default: break;
	}
	return bRet;
}


int main(int argc, char *argv[])
{
	char *path = "c://1.exe";

	// 0 加载服务    1 启动服务    2 停止服务    3 删除服务
	SystemServiceOperate(path, 3);

	system("pause");
	return 0;
}
