New Credit Card Scam

New Credit Card Scam

From Bruce Schneier.

“This one is clever. You receive a telephone call from someone purporting to be from your credit card company. They claim to be from something like the security and fraud department, and question you about a fake purchase for some amount close to $500.

When you say that the purchase wasn’t yours, they tell you that they’re tracking the fraudsters and that you will receive a credit. They tell you that the fraudsters are making fake purchases on cards for amounts just under $500, and that they’re on the case.

They know your account number. They know your name and address. They continue to spin the story, and eventually get you to reveal the three extra numbers on the back of your card.

That’s all they need. They then start charging your card for amounts just under $500. When you get your bill, you’re unlikely to call the credit card company because you already know that they’re on the case and that you’ll receive a credit.

It’s a really clever social engineering attack. They have to hit a lot of cards fast and then disappear, because otherwise they can be tracked, but I bet they’ve made a lot of money so far.”
