Security experts call this new scam "vishing" -- short for "voice phishing."
Sometimes vishing begins with a phone call, not an e-mail. And these calls are quite believable, because the caller already knows your credit card number. All you are asked to provide is the three-digit security code found on the back of the card. "It is becoming more difficult to distinguish phishing attempts from actual attempts to contact customers," Ron O'Brien, a security analyst with Sophos PLC, told the AP.
Here is the valuable lesson: "If you get a telephone call where someone is asking you to provide or confirm any of your personal information, immediately hang up and call your financial institution with the number on the back of the card," Paul Henry, a vice president with Secure Computing Corp. told AP. "If it was a real issue, they can address the issue."
