ATM Skimmer Powered by MP3 Player
Krebs on Security blogs about ATM skimmers made of parts from old MP3 players. Using audio to capture credit and debit card data is not a new technique, but it is becoming vogue: Square, an increasingly popular credit card reader built for the iPhone, works by plugging into the headphone jack on the iPhone and converting credit card data stored on the card into audio files. The card skimmer is designed to fit over the card acceptance slot on an ATM. When a card is slid past the magnetic reader, the MP3 player “hears” the data stored on the card’s magnetic stripe, and records it as an audio file to a tiny embedded flash memory device.
