what is wp_wfHits actually showing?

HI, I’m dealing with a hacked site cleanup. Just curious what the table wp_wfHits is actually showing? In there are many many references to what I think are injected query-string refernces to this site, for example https://www.their-domain.com/?dailynotes=35568&items=3&articles=5568. As I clean up the site, I need to know whether this is indicative of an ongoing problem or something that will stop with time…
