The Island's Cyber Security Centre is warning people about phone calls from scammers pretending to be from the online bank Revolut.
On Facebook, it says it's had a number of reports where the scammers already have people's names and other details.
It's advising people to be careful if they get unexpected calls from banks about suspicious or fraudulent transactions.
And it says if you get one, you should avoid giving any details, hang up and call your bank on its official number.
