七、回调

7.1.进程回调

DriverMain.c

代码语言：javascript复制

#include <ntifs.h>

PUCHAR PsGetProcessImageFileName(PEPROCESS Process);

//创建进程回调函数
VOID CreateProcessListen(
	_In_ HANDLE ParentId,
	_In_ HANDLE ProcessId,
	_In_ BOOLEAN Create
)
{
	PEPROCESS Process = NULL;
	NTSTATUS status = PsLookupProcessByProcessId(ProcessId, &Process);
	if (!NT_SUCCESS(status))
	{
		return;
	}

	//创建进程
	if (Create)
	{
		DbgPrintEx(77,0,"[db]:%s 创建了rn", PsGetProcessImageFileName(Process));
	}
	else
	{
		DbgPrintEx(77, 0, "[db]:%s 退出了rn", PsGetProcessImageFileName(Process));
	}
    
	ObDereferenceObject(Process);
}


VOID DriverUnload(PDRIVER_OBJECT pDriverObject)
{
	PsSetCreateProcessNotifyRoutine(CreateProcessListen, TRUE);
	DbgPrint("卸载驱动rn");
}

NTSTATUS DriverEntry(PDRIVER_OBJECT pDriver, PUNICODE_STRING pReg)
{
    //创建进程回调
	PsSetCreateProcessNotifyRoutine(CreateProcessListen,FALSE);

	pDriver->DriverUnload = DriverUnload;

	return STATUS_SUCCESS;
}

修改PspNotifyEnableMask为00000009，创建和退出进程时就不会触发回调

代码语言：javascript复制

kd> dd PspNotifyEnableMask
83f4c838  0000000b 00000000 8ad0e54f 00000000

kd> ed 83f4c838 00000009
kd> g

7.2.线程回调

DriverMain.c

代码语言：javascript复制

#include <ntifs.h>

PUCHAR PsGetProcessImageFileName(PEPROCESS Process);

VOID CreateProcessListen(
	_In_ HANDLE ParentId,
	_In_ HANDLE ProcessId,
	_In_ BOOLEAN Create
)
{
	PEPROCESS Process = NULL;
	NTSTATUS status = PsLookupProcessByProcessId(ProcessId, &Process);
	if (!NT_SUCCESS(status))
	{
		return;
	}

	//创建进程
	if (Create)
	{
		DbgPrintEx(77,0,"[db]:%s 创建了rn", PsGetProcessImageFileName(Process));
	}
	else
	{
		DbgPrintEx(77, 0, "[db]:%s 退出了rn", PsGetProcessImageFileName(Process));
	}
	
    ObDereferenceObject(Process);
}


VOID createThreadListen(
	_In_ HANDLE ProcessId,
	_In_ HANDLE ThreadId,
	_In_ BOOLEAN Create
)
{
	if (Create)
	{
		DbgPrintEx(77, 0, "[db]线程创建了rn");
	}
	else
	{
		DbgPrintEx(77, 0, "[db]线程结束了rn");
	}
}


VOID DriverUnload(PDRIVER_OBJECT pDriverObject)
{
	//PsSetCreateProcessNotifyRoutine(CreateProcessListen, TRUE);

	PsRemoveCreateThreadNotifyRoutine(createThreadListen);

	DbgPrint("卸载驱动rn");
}

NTSTATUS DriverEntry(PDRIVER_OBJECT pDriver, PUNICODE_STRING pReg)
{
	//PsSetCreateProcessNotifyRoutine(CreateProcessListen,FALSE);

	PsSetCreateThreadNotifyRoutine(createThreadListen);


	pDriver->DriverUnload = DriverUnload;

	return STATUS_SUCCESS;
}

修改PspNotifyEnableMask为00000007,创建和退出线程时就不会触发回调

7.3.模块回调

DriverMain.c

代码语言：javascript复制

#include <ntifs.h>

PUCHAR PsGetProcessImageFileName(PEPROCESS Process);

VOID CreateProcessListen(
	_In_ HANDLE ParentId,
	_In_ HANDLE ProcessId,
	_In_ BOOLEAN Create
)
{
	PEPROCESS Process = NULL;
	NTSTATUS status = PsLookupProcessByProcessId(ProcessId, &Process);
	if (!NT_SUCCESS(status))
	{
		return;
	}

	//创建进程
	if (Create)
	{
		DbgPrintEx(77,0,"[db]:%s 创建了rn", PsGetProcessImageFileName(Process));
	}
	else
	{
		DbgPrintEx(77, 0, "[db]:%s 退出了rn", PsGetProcessImageFileName(Process));
	}
    
	ObDereferenceObject(Process);
}


VOID createThreadListen(
	_In_ HANDLE ProcessId,
	_In_ HANDLE ThreadId,
	_In_ BOOLEAN Create
)
{
	if (Create)
	{
		DbgPrintEx(77, 0, "[db]线程创建了rn");
	}
	else
	{
		DbgPrintEx(77, 0, "[db]线程结束了rn");
	}
}

VOID LoadImageListen(
	_In_opt_ PUNICODE_STRING FullImageName,
	_In_ HANDLE ProcessId,                // pid into which image is being mapped
	_In_ PIMAGE_INFO ImageInfo
)
{
	if (ImageInfo->SystemModeImage)
	{
		DbgPrintEx(77, 0, "[db]驱动模块: %wZrn", FullImageName);
	}
	else
	{
		DbgPrintEx(77, 0, "[db]普通DLL: %wZrn", FullImageName);
	}
}


VOID DriverUnload(PDRIVER_OBJECT pDriverObject)
{
	//PsSetCreateProcessNotifyRoutine(CreateProcessListen, TRUE);

	//PsRemoveCreateThreadNotifyRoutine(createThreadListen);

	PsRemoveLoadImageNotifyRoutine(LoadImageListen);

	DbgPrint("卸载驱动rn");
}

NTSTATUS DriverEntry(PDRIVER_OBJECT pDriver, PUNICODE_STRING pReg)
{
	//PsSetCreateProcessNotifyRoutine(CreateProcessListen,FALSE);

	//PsSetCreateThreadNotifyRoutine(createThreadListen);

	PsSetLoadImageNotifyRoutine(LoadImageListen);


	pDriver->DriverUnload = DriverUnload;

	return STATUS_SUCCESS;
}

_IMAGE_INFO结构体

代码语言：javascript复制

typedef struct _IMAGE_INFO {
    union {
        ULONG Properties;
        struct {
            ULONG ImageAddressingMode  : 8;  // Code addressing mode
            ULONG SystemModeImage      : 1;  // System mode image
            ULONG ImageMappedToAllPids : 1;  // Image mapped into all processes
            ULONG ExtendedInfoPresent  : 1;  // IMAGE_INFO_EX available
            ULONG MachineTypeMismatch  : 1;  // Architecture type mismatch
            ULONG ImageSignatureLevel  : 4;  // Signature level
            ULONG ImageSignatureType   : 3;  // Signature type
            ULONG ImagePartialMap      : 1;  // Nonzero if entire image is not mapped
            ULONG Reserved             : 12;
        };
    };
    PVOID       ImageBase;
    ULONG       ImageSelector;
    SIZE_T      ImageSize;
    ULONG       ImageSectionNumber;
} IMAGE_INFO, *PIMAGE_INFO;

修改PspNotifyEnableMask为0000000e,就不会触发模块回调
