Re: Are European cards vulnerable?
It depends, can you process transactions without verification? Some schemes I'm familiar with like Secured by Visa/Mastercard Securecode only work if supported by the vendor, so they'd just use your card at an unsupported vendor. If it doesn't require vendor support (unsupported vendors would have to be deined), and you can't use the card to make point of sale transactions on a magnetic (not chip) card, then you're probably safe. But it would be my guess, that is probably not the case.
I'd call your credit card provider and ask them to cancel and replace that card.
