I know it is pedantic but it is important to keep in mind because dumping the need to seek redress on the uninvolved third party is ridiculous, so we shouldn’t use language that plays into that point of view.
It's merely a tort (wrong). It never rises to the level of a crime. The few instances/places where slander is a crime in the US (historically or otherwise) are very problematic and subject to abuse.
Perhaps this specific kind of slander should be criminal, but it might be the only kind that should be. Not only would you need to justify that philosophically, but somehow convince legislators to make it that way (at the federal level, I should think).
It'd be a tough journey.
Agreed that getting legislators to do anything about it will be a pain, though.
This is called libel. This person is a victim of a crime the credit reporting agency committed.
