Credit card data theft just got a lot harder to prevent

ATM skimmers, the miniature devices that stealthily help fraudsters capture your credit and debit card data, are getting smaller and harder to detect. Skimmers have always been designed to blend in with any ATM they’re attached to, but for years a discerning eye or tug of the card reader were often enough to uncover them. That’s not the case anymore. Krebs on Security has been researching a number of devices recovered in Europe this year, and several of them were small enough to fit inside the ATM card slot itself. The ultra-thin profile of these “insert skimmers” makes them far less obvious to your average person making a quick stop at the cash machine.
