Dark matter is a hypothesis to explain departure from Newtonian gravity on large scale structure i.e galactic clusters. All have failed.

Dark matter is defined as non luminate non bsryon matter.

Andrew Worsley

Yes, subsolar mass black hole objects in the halo. Plus supermassive black hole objects at the centre of the galaxy. In short Increase gravity by black holes.
