Pro-Grade Point-of-Sale Skimmer

February 1, 2013

Every so often, the sophistication of the technology being built into credit card skimmers amazes even the experts who are accustomed to studying such crimeware. This post focuses on one such example — images from one of several compromised point-of-sale devices that used Bluetooth technology to send the stolen data to the fraudsters wirelessly.

Point-of-Sale Skimmers: No Charge…Yet

December 18, 2012

If you hand your credit or debit card to a merchant who is using a wireless point-of-sale (POS) device, you may want to later verify that the charge actually went through. A top vendor of POS skimmers ships devices that will print out “transaction approved” receipts, even though the machine is offline and is merely recording the customer’s card data and PIN for future fraudulent use.

This blog has featured stories about a vast array of impressive, high-tech devices used to steal money from automated teller machines (ATMs).

Pro Grade (3D Printer-Made?) ATM Skimmer

December 7, 2011

In July 2011, a customer at a Chase Bank branch in West Hills, Calif. noticed something odd about the ATM he was using and reported it to police. Authorities who responded to the incident discovered a sophisticated, professional-grade ATM skimmer that they believe was made with the help of a 3D printer.

ATM Skimmer Powered by MP3 Player

October 13, 2011

Almost a year ago, I wrote about ATM skimmers made of parts cannibalized from old MP3 players. Since then, I’ve noticed quite a few more ads for these MP3-powered skimmers in the criminal underground, perhaps because audio skimmers allow fraudsters to sell lucrative service contracts along with their theft devices.

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.
