I added to my comment, but when you call the number, you talk to the attacker and they ask you questions about you and your account. Maybe they try to buy crypto with it or they prime you to go to some attack website and use your paypal account to buy something.

oh no, not at all.

They will attempt to get you to install AnyDesk or some kind of remote software and then pwn your computer. They will remote in "to fix the hack" because your computer is obviously infected with a virus. Then either just steal your money from your bank account or etc.
