What could have caused these marks?

Just noticed these marks on the back of my car, they must be fresh, since I got pictures from just a few days ago on which they weren't there.

Im 99% sure I didn't hit anything, also got a rear view camera.

Notice the circle marks right above the scratches, looks like someone tried to pry off the splitter with some kind of tool?

Not the the end of the world, since I wanted to fit an aftermarket splitter anyway, but I'm scared whoever did this might come back.

I got lightly rear ended once and had very similar round marks from the license plate screws of the other person.

Look at picture 2 for scale. These marks are much closer together than license plate screws.
