Phobos is Hollow?

Apparently there's some data from at least two of the spacecraft orbiting Mars that indicates that about 1/3 of the volume of Phobos is empty.  I haven't been able to locate the original reports of this.  For all I know, this simply means that Phobos is really just a loose collection of boulders with lots of empty space between them – or possibly even the conclusions about the data are misrepresented. 

But whatever the data and conclusions are, the tin-foil hat brigade is already at it...
