Probably simulations, and they are only as good as the data which is fed. But it makes no sense. Just like the last scene in the movie "Star Trek".
Having said that, I don't doubt that such black holes can't exist. After all, we do expect at least a few supernovas to meet that fate, and there just might be one in our neighborhood. After all, there is some credit given to a supernova event that was followed by the solar neighborhood, for relative abundance of gold.
It's from a simulation that was made at NYU's Center for Cosmology and Particle Physics, according to the article. What's been described is a method to detect of such activity IF primordial black holes exist and IF one were to penetrate or graze one of the numerous stars being observed. Chances are very small for such an event to occur to any given star, but out of around 100 billion stars in the galaxy, some collisions are bound to take place. These things wouldn't do much passing through a star other than cause noticable vibrations.
While primordial black holes are theoretically possible, I'm not sure how such a proposed ripple effect could be conclusively determined as having actually been caused by such a black hole. There are a lot of unanswered questions. How would you know such a ripple wasn't caused by a star quake, or twisting of the magnetic fields? Just how long would it take for such a black hole to pass through a star? What would happen if a primordial black hole passed through a rocky planet like the Earth (even though chances of that ever happening are practically zilch)?
Where I have a problem with mere vibrations is that even planets with pitiful mass compared to the parent star create disturbances in the star. And for a body to be a black hole, would necessitate a mass that generates enough gravity for the black hole to exist in the first place.

I agree that it would be difficult to conclude such a disturbance is caused by a primordial black hole. From what I can understand, they may have originated in the early universe before there were any stars, and that they are very small, some perhaps the size of an atom with the mass of an asteroid. They're too small to consume a star, but could pass through one causing a disturbance. Apart from the math, there's no evidence they exist, but it is possible.

“That’s a long time to stare at our sun, waiting for the event.” (a bit of humor, there...)
