It seems so incredibly unsurprising and mundane that given the particle zoo that we have that it might include a set of particles that interact very weakly with the electromagnetic field and so are extremely difficult for us to directly detect.
That of course doesn't say one way or another that such hypothetical particles can account for the amount of mass needed.
