HookMutex

我是個驅動新手，最近學習破解多開。經過一個通宵的百度和摸索，簡單的多開kugou用以下程式碼可以了。

MyNtCreateMutant(
          OUT PHANDLE MutantHandle,
          IN ACCESS_MASK DesiredAccess,
          IN POBJECT_ATTRIBUTES ObjectAttributes,
          IN BOOLEAN InitialOwner
          )
{
  
  NTSTATUS nStatus;
  UNICODE_STRING DestinationString,DestinationString2;
  WCHAR WC_MyId;
  RtlInitUnicodeString(&DestinationString, L"Kugoo7");  //MSangoClientNew
  RtlInitUnicodeString(&DestinationString2, L"Kugou7MainFormMutex");

  if (ObjectAttributes && RtlEqualUnicodeString(&DestinationString, ObjectAttributes->ObjectName, 0))
  {
    KdPrint(("Kugoo7\n"));
    ULONG MyId = (ULONG)PsGetCurrentProcessId();
    KdPrint(("PsGetCurrentProcessId = %u\r\n",MyId));

    UNICODE_STRING UnicodeString2={0};
    UnicodeString2.Buffer = (PWSTR)ExAllocatePool(PagedPool,1024);
    UnicodeString2.MaximumLength = 1024;
    nStatus = RtlIntegerToUnicodeString(MyId,10,&UnicodeString2);

    if ( NT_SUCCESS(nStatus))
    {
      KdPrint(("轉換字串成功! 結果:%wZ\n",&UnicodeString2));
      RtlCopyUnicodeString(ObjectAttributes->ObjectName,&UnicodeString2);
      return g_pfnCreateMutant(MutantHandle,DesiredAccess,ObjectAttributes,InitialOwner);
    }else
    {
      KdPrint(("轉換字串 失敗!\n"));
      return STATUS_SUCCESS;
    }
    
  }

  
  return g_pfnCreateMutant(MutantHandle,DesiredAccess,ObjectAttributes,InitialOwner);
}
