Like most electronic gadgets these days, ATM skimmers are getting smaller and thinner, with extended battery life. Here’s a look at several miniaturized fraud devices that were pulled from compromised cash machines at various ATMs in Europe so far this year.
According to a new report from the European ATM Security Team (EAST), a novel form of mini-skimmer was reported by one country. Pictured below is a device designed to capture the data stored on an ATM card’s magnetic stripe as the card is inserted into the machine. While most card skimmers are made to sit directly on top of the existing card slot, these newer mini-skimmers fit snugly inside the card reader throat, obscuring most of the device. This card skimmer was made to fit inside certain kinds of cash machines made by NCR.
“New versions of insert skimmers (skimmers placed inside the card reader throat) are getting harder to detect,” the EAST report concludes.
The miniaturized insert skimmer above was used in tandem with a tiny spy camera to record each customer’s PIN. The image on the left shows the hidden camera situated just to the left of the large square battery; the photo on the right shows the false ATM fascia that obscures the hidden camera as it was found attached to the compromised ATM (notice the tiny pinhole at the top left edge of the device).
EAST notes that the same country which reported discovering the skimmer devices above also found an ATM that was compromised by a new type of translucent insert skimmer, pictured below.
