Nobody really knows of course. However it is safe to assume they are not so stupid as to ignore what is happening in the other areas (at least some of them), and so they are running their own targeted scans and then trying to figure out how to make money (or whatever their goal is) by exploiting them. They are also using LLMs to try things on closed source that are more than a brute force attack, though I have no idea what those would be.
