See if the keyboard is securely attached and just one piece. Skimmers read the magnetic stripe as the card is inserted, so give the card a bit of a wiggle as you put it in, Tanase advised.The reader needs the stripe to go in a single motion, because if it isn't straight in, it can't read the data correctly.The chances of getting hit by a skimmer are higher on the weekend than during the week, since it's harder for customers to report the suspicious ATMs to the bank.Criminals typically install skimmers on Saturdays or Sundays, and then remove them before the banks reopen on Monday.Obtaining the PIN is essential, since the criminals can't use the stolen magnetic stripe data without it, Tanase said.Of course, that assumes the attacker is using a camera and not an overlay to obtain your PIN.
When you are pumping gas or grabbing some money for lunch out of the ATM, the last thing you want to worry about is your card information getting stolen. Check for Tampering When you approach an ATM, check for some obvious signs of tampering at the top of the ATM, near the speakers, the side of the screen, the card reader itself, and the keyboard.
Every swipe is read as a keyboard entry, with no extra setup required.
More advanced devices to steal your information are installed by criminals directly on to ATMs and credit card readers.
Criminals frequently install skimmers on ATMs that aren't located in overly busy locations since they don't want to be observed installing malicious hardware or collecting the harvested data.
The ATMs inside banks are generally safer because of all the cameras, although some daring criminals do still succeed at installing them there.
