Equifax settlement claim, scam or legit?

I received an email tonight stating “You have a valid claim and are eligible for an additional payment” and they will be reaching out to me the week of December 2nd. I don’t recall signing up for any sort of class action lawsuit so I am incredibly confused. Is this a scam or something I was just automatically signed up for? I don’t recall ever having an account with them nor do I ever check my credit. I googled and apparently there was something way back in 2017 but I can’t find much else. Am I right to assume it’s some sort of scam looking to farm information?
