Chip Card ATM ‘Shimmer’ Found in Mexico

Fraud experts in Mexico have discovered an unusual ATM skimming device that can be inserted into the mouth of the cash machine’s card acceptance slot and used to read data directly off of chip-enabled credit or debit cards.

According to information from Damage Control S.A., a security and investigations company based in Mexico, this device was found inside a Diebold Opteva 520 with Dip reader (the kind of card reader that requires you to briefly insert your card and then quickly remove it). The device is inserted from the outside of the ATM and no access is required to the ATM internals. Damage Control, which disseminated the information via a service called CrimeDex, didn’t say whether this shimmer was accompanied by a component to steal card PINs, such as a hidden camera or PIN pad overlay.
