Police in an unidentified European nation have retrieved wafer-thin ATM skimmers that are so small that they can be fitted inside the credit-card insertion slot. Brian Krebs describes the finding:
That's according to two recent reports from the European ATM Security Team (EAST), an organization that collects ATM fraud reports from countries in the region. In both reports, EAST said one country (it isn't naming which) alerted them about a new form of skimming device that is thin enough to be inserted directly into the card reader slot. These devices record the data stored on the magnetic stripe on the back of the card as it is slid into a compromised ATM.
Another EAST report released this week indicates that these insert skimmers are continuing to evolve. Below are two more such devices. Insert skimmers require some secondary component to record customers entering their PINs, such as a PIN pad overlay or hidden camera.
