Crooks who make and deploy ATM skimmers are constantly engaged in a cat-and-mouse game with financial institutions, which deploy a variety of technological measures designed to defeat skimming devices. The latest innovation aimed at tipping the scales in favor of skimmer thieves is a small, battery powered device that provides crooks a digital readout indicating whether an ATM likely includes digital anti-skimming technology.
I recently heard from a police detective who was seeking help identifying some strange devices found on two Romanian men caught maxing out stolen credit cards at local retailers. Further inspection revealed the devices to be semi-flexible data transfer wands that thieves can use to extract stolen ATM card data from “deep-insert skimmers,” wafer-thin fraud devices made to be hidden inside of the card acceptance slot on a cash machine.
ATM maker NCR Corp. says it is seeing a rapid rise in reports of what it calls “deep insert skimmers,” wafer-thin fraud devices made to be hidden inside of the card acceptance slot on a cash machine.
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.
Previous stories here about ATM skimming attacks have focused on innovative fraud devices made to attach to the outside of compromised ATMs. Security experts are now warning about a new class of skimming scams aimed at draining ATM cash deposits via a novel and complex attack designed to empty affected ATMs of all available cash.
