Gone Vishin’

It’s 9:30 at night when the phone rings.

The Caller ID displays “Card Services” and a toll-free number.

You pick up the phone, and an automated voice informs you that “your card has been compromised.” It gives you a phone number to call to take care of the issue. The phone number is the same number on the Caller ID display.

Now…what should you do?

If you answered, “hang up and ignore the call,” you’re right.

Currently, there is a move towards integrating older technologies with the Internet. Eventually, I believe these technologies will be fully integrated; your television signal, Internet connection and telephone service will all be traveling along the exact same lines as part of the same service. These different technologies will also become more “seamless” over time—there will be less of a distinct divide between how you use your TV and your computer, and between the content you will receive from both. Okay, you’ll probably still use your phone to call Mom, but the signal will be digital, and it will be traveling through the Internet.

However, there is a downside, at least for the time being: vishing. Using Internet telephone services (Voice over Internet Protocol, or VoIP), criminals are able to spoof Caller ID information, to make a phone call appear to be from a trusted entity such as a financial institution or credit card issuer.

Let’s face it, you’re more likely to believe a call from “Card Services” than you are a “Blocked Call” or “Unknown Caller.” And that’s the basis of how Vishing works.

What happens if you call the number as instructed? You will be instructed to enter your credit or debit card number, expiration date, PIN and other security information. This is pretty much everything a crook needs to use your card for fraudulent purposes. They might also attempt to get your personal information, such as date of birth or Social Security number—basically, everything they would need to commit identity theft.
