Good that you posted this to pass info to others. DH fell for this scam a few years ago and it was lucky he told me about it because we contacted Pay Pal right away. We cancelled credit cards, etc. so nothing bad happened except Pay Pal closed his account and it was flagged that he did something wrong.
Beware of phone calls saying there is nothing wrong but they are checking or updating your credit card info. Another scam going on.
