It's about augments in the specific nebula where the Genesis planet was and it has a ground portion in that nebula.
There are other possibilities. The augment making guy who you encounter in the Fed storyline may have set up a lab there in honor of Khan, for example. It would probably be a pretty good place to hide one. Or the ground portion could be on another ship in the Nebula, maybe somebody trying to harvest Genesis energy (or protomatter) from the planets remains. Lots of possibilities at this point.
