ATM information theft is nothing new. Neither is the use of skimmers to gain access to the data. But it’s a little surprising just how easy it has become to hack together the devices using audio equipment. The images above are samples of a skimmer for sale from an Eastern-European do-no-good. It is the magnetic stripe sniffer portion of the attack which captures card data as an audio recording. That is later turned into the binary code that was read from the card. We’re just speculating, but that looks an awful lot like the PCB from a pen recorder, something you can pick up for just a couple of bucks.
Of course this is used in conjunction with a camera to capture PIN data as the second part of the security protocol, but it really underscores the need for new ATM technology. Some skimmers don’t even require retrieval of the hardware, and you never know where the sketchy machines might pop up next.
