遍历windows驱动

驱动都存在

\\Driver 或者 \\FileSystem 目录对象里 我们只需要遍历这两个目录就可以遍历windows所有驱动

知识点

\\Driver  \\FileSystem (dt _OBJECT_DIRECOTRY)都属于 ObpDirectoryObjectType(window内核全局变量) 对象

其他对象全局变量 可以参考 作者:潘爱民 书名:windows内核原理与实现 的 2.4图

一个目录对象 含有37个DirectoryEnTry 对象(dt _OBJECT_DIRECTORY_ENTRY)

_OBJECT_DIRECTORY_ENTRY 里的Object 指向的就是 驱动的 DriverObject( dt _DRIVER_OBJECT)

具体内容看代码

VOID init()

{

UNICODE_STRING vDriverName = { 0 };

RtlInitUnicodeString(&vDriverName, L"\\Driver");

POBJECT_DIRECTORY vPObjectDirectory;

NTSTATUS vStatus;

vStatus = ObReferenceObjectByName(

&vDriverName,

OBJ_CASE_INSENSITIVE | OBJ_KERNEL_HANDLE,

NULL,

0,

(POBJECT_TYPE)0x869d0040,

KernelMode,

NULL,

(PVOID *)&vPObjectDirectory

);

if (NT_SUCCESS(vStatus))

{

KdPrint(("成功"));

for (ULONG vI = 0; vI < NUMBER_HASH_BUCKETS; vI++)

{

PDRIVER_OBJECT vDriverObject = NULL;

POBJECT_DIRECTORY_ENTRY vObjectDirectoryEntry = NULL;

vObjectDirectoryEntry = vPObjectDirectory->HashBuckets[vI];

while (vObjectDirectoryEntry && MmIsAddressValid((PVOID)vObjectDirectoryEntry))

{

vDriverObject = (PDRIVER_OBJECT)vObjectDirectoryEntry->Object;

if (MmIsAddressValid((PVOID)vDriverObject))

{

if (MmIsAddressValid(&vDriverObject->DriverName))

{

if (wcsstr(vDriverObject->DriverName.Buffer, L"PCHunter32") != NULL)

{

KdPrint(("\r\n\r\n找到了\r\n\r\n"));

RtlInitUnicodeString(&vDriverObject->DriverName, L"\Driver\text32");

}

KdPrint(("名:%wZ\r\n", &vDriverObject->DriverName));

}

}

vObjectDirectoryEntry = vObjectDirectoryEntry->ChainLink;

}

}

ObDereferenceObject(vPObjectDirectory);

}

else

KdPrint(("vStatus = 0x%08X\r\n", vStatus));

RtlInitUnicodeString(&vDriverName, L"\\FileSystem");

vStatus = ObReferenceObjectByName(

&vDriverName,

OBJ_CASE_INSENSITIVE | OBJ_KERNEL_HANDLE,

NULL,

0,

(POBJECT_TYPE)0x869d0040,

KernelMode,

NULL,

(PVOID *)&vPObjectDirectory

);

if (NT_SUCCESS(vStatus))

{

KdPrint(("成功"));

for (ULONG vI = 0; vI < NUMBER_HASH_BUCKETS; vI++)

{

PDRIVER_OBJECT vDriverObject = NULL;

POBJECT_DIRECTORY_ENTRY vObjectDirectoryEntry = NULL;

vObjectDirectoryEntry = vPObjectDirectory->HashBuckets[vI];

while (vObjectDirectoryEntry && MmIsAddressValid((PVOID)vObjectDirectoryEntry))

{

vDriverObject = (PDRIVER_OBJECT)vObjectDirectoryEntry->Object;

if (MmIsAddressValid((PVOID)vDriverObject))

{

if (MmIsAddressValid(&vDriverObject->DriverName))

{

KdPrint(("名:%wZ\r\n", &vDriverObject->DriverName));

}

}

vObjectDirectoryEntry = vObjectDirectoryEntry->ChainLink;

}

}

ObDereferenceObject(vPObjectDirectory);

}

else

KdPrint(("vStatus = 0x%08X\r\n", vStatus));

}
