使用NtCreateKey()NTAPI函数[NtOpenKey()函数创建新的注册表项会返回一个NTSTATUS错误值

Question

我编写了以下代码来在注册表中创建一个新键，但当尝试获取基键的句柄以创建新键时，NtOpenKey()函数会返回NTSTATUS错误值-1073741772。

typedef NTSTATUS(*LPCREATEKEY) (PHANDLE, ACCESS_MASK, POBJECT_ATTRIBUTES, ULONG, PUNICODE_STRING, ULONG, PULONG);
typedef NTSTATUS(*LPOPENKEY) (PHANDLE, ACCESS_MASK, POBJECT_ATTRIBUTES);
HINSTANCE dllHandle = nullptr;
LPCREATEKEY createKey = nullptr;
LPOPENKEY openKey = nullptr;
NTSTATUS opStatus = NULL;
HANDLE key = nullptr, baseKey = nullptr;
OBJECT_ATTRIBUTES keyAttributes;
WCHAR keyStr[] = L"XYZ", baseKeyStr[] = L"\REGISTRY\MACHINE\SOFTWARE";
UNICODE_STRING keyName, baseKeyName;
ULONG keyDispositionValue = NULL;
dllHandle = LoadLibrary(L"Ntdll.dll");
if (nullptr != dllHandle) {
// Fetch the function to create a new registry key
createKey = (LPCREATEKEY)GetProcAddress(dllHandle, "NtCreateKey");
openKey = (LPOPENKEY)GetProcAddress(dllHandle, "NtOpenKey");
if (nullptr != createKey && nullptr != openKey) {
baseKeyName.Buffer = baseKeyStr;
baseKeyName.Length = wcslen(baseKeyStr);
baseKeyName.MaximumLength = wcslen(baseKeyStr);
InitializeObjectAttributes(&keyAttributes, 
&baseKeyName,
OBJ_CASE_INSENSITIVE, 
NULL, 
NULL);
opStatus = openKey(&baseKey, KEY_ALL_ACCESS, &keyAttributes);
if (NT_SUCCESS(opStatus)) {
keyName.Buffer = keyStr;
keyName.Length = wcslen(keyStr);
keyName.MaximumLength = wcslen(keyStr);
InitializeObjectAttributes(&keyAttributes,
&keyName,
OBJ_CASE_INSENSITIVE,
&baseKey,
NULL);
opStatus = createKey(
&key,
KEY_ALL_ACCESS,
&keyAttributes,
NULL,
NULL,
REG_OPTION_NON_VOLATILE,
&keyDispositionValue);
if (NT_SUCCESS(opStatus)) {
cout << "Key successfully created!n";
//NtClose()
if (!NT_SUCCESS(CloseHandle(key)))
cout << "Error closing created key handlen";
}
if (!NT_SUCCESS(CloseHandle(baseKey)))
cout << "Error closing base key handlen";
}
else {
if (NT_ERROR(opStatus))
cout << "Error opening the base key (" << opStatus << ")n";
}
}
else {
cout << "Could not fetch the functions from the DLLn";
}
FreeLibrary(dllHandle);
}
else {
cout << "Could not access Ntdll.dlln";
}

提前谢谢。

这就是使用NTAPI函数在注册表中创建新键的方式。

#include <winternl.h>
typedef NTSTATUS(*LPCREATEKEY) (PHANDLE, ACCESS_MASK, POBJECT_ATTRIBUTES, ULONG, PUNICODE_STRING, ULONG, PULONG);
HINSTANCE dll = nullptr;
LPCREATEKEY ntCreateKey = nullptr;
HANDLE createdKey = nullptr;
UNICODE_STRING newKeyName;
OBJECT_ATTRIBUTES attributes;
WCHAR name[] = L"\REGISTRY\MACHINE\SOFTWARE\NewKeyName";
NTSTATUS opStatus = NULL;
ULONG keyDispositionValue = NULL;
dll = LoadLibrary(L"Ntdll.dll");
if (nullptr != dll) {
ntCreateKey = (LPCREATEKEY) GetProcAddress(dll, "NtCreateKey");
if (nullptr != ntCreateKey) {
newKeyName.Buffer = name;
newKeyName.Length = sizeof(name) - sizeof(WCHAR);
newKeyName.MaximumLength = wcslen(name);
InitializeObjectAttributes(&attributes, &newKeyName, OBJ_CASE_INSENSITIVE, NULL, NULL);
opStatus = ntCreateKey(&createdKey, KEY_ALL_ACCESS, &attributes, 0, NULL, REG_OPTION_NON_VOLATILE, &keyDispositionValue);
if (NT_SUCCESS(opStatus)) {
if (keyDispositionValue == REG_CREATED_NEW_KEY)
cout << "New key created!n";
else if (keyDispositionValue == REG_OPENED_EXISTING_KEY)
cout << "Key already exists!n";
if (!CloseHandle(createdKey))
cout << "Error closing handle!";
}
else {
printf("%X", opStatus);
}
}
else {
cout << "Could not fetch NtCreateKey() from Ntdll.dlln";
}
FreeLibrary(dll);
}
else {
cout << "Could not access Ntdll.dlln";
}
