Opening File Object handle through Device Name

NTFSD
1

Is it possible to open a handle to a device having only its device object.
We don’t have its device name nor having its symbolic link.
I donot mean that they exists but we donot have them. We only have the
device object corrsponding to device and we want to open a handle to it

I think ObOpenObjectByPointer would give a handle, never tried though.

And you can’t figure this out with the free tools OSR or Sysinternals
offer for download? Windbg can’t tell you this??

ObQueryNameString on the device, then the usual ZwCreateFile
