Someone Looking Over Your Shoulder
Do you ever have that creepy feeling that you're being watched
-- that someone you can't see is looking over your shoulder? It may be
more than just your imagination, especially if you're using an ATM card
at your bank or gas station.
Thieves are out there watching, often with telescopes or cameras
with long telephoto lenses. They are watching your hands punch your
personal identification number into the terminal. The next step is to
make a copy of your ATM card. That's easier than you may think. All
they need is your account number and a device that imprints that number
on the magnetic strip of a blank credit card.
Those account numbers are plentiful. There are trash cans and
waste baskets full of them around every automated teller machine.
People just throw them away, not realizing that a clever thief can use
the numbers printed on those receipts to manufacture duplicate ATM
cards. Passers then use those cards to drain cash from victims' bank
accounts until either the money is gone or the card access is canceled
by the bank.
I've seen these watchers, these so-called "shoulder surfers," at
work in New York City. It was a couple of years ago at the Port
Authority Terminal, where I was shooting a story on phone fraud. My
cameraman and I saw "surfers" spying on callers as they punched their
calling-card numbers on pay phones. Those numbers were later sold on
the street for $20 to $50 apiece.
More recently, two enterprising thieves in New York installed a
small video camera over an ATM to record people as they made their
transactions. They also provided a handy tray to dispose of the ATM
receipts. They put the information together and ripped off the banks
for $1.4 million in only six days.
This is also happening at service stations where people use
their ATM cards to buy gas. The terminal is usually mounted on a post
near the pumps in plain view of anyone nearby. All the surfer has to do
is watch for those customers who throw their gas receipts in the trash,
and they have the makings of a counterfeit card. Arco is now lowering
their ATM terminals so the customer's body blocks the view of the
keypad.
One device that might foil shoulder surfers is the kind of
digital keypad we have on our news room security system. There are no
numbers printed on the keys. Instead, the person at the door presses a
button that reveals lighted num- bers behind the keys in random order.
That number pattern is different every time the button is pushed and
can be seen only by someone standing directly in front of the keypad.
Here are some tips to avoid being ripped off: -- Memorize your
PIN number. Don't write it on your card or carry it in your wallet.
-- Don't choose obvious number sequences, like 1-2-3-4, your
address or your birth date.
These are the first numbers a thief would try if he or she had your
wallet.
-- Cover the ATM keypad with your hand or body when entering
your access code.
-- Take your receipts with you. If you don't want them for your
bank records, at least throw them away elsewhere.
