The US Secret Service is warning banks and ATM vendors about a new ATM skimmer technology, the so-called ‘periscope skimming.’ The device is composed of a skimming probe that crooks connect to the ATM’s internal circuit board in order to steal card data.
The popular cyber security expert Brian Krebs published the images of the periscope skimming, the photos show the wires protruding from the periscope.
Authorities believe the samples of periscope skimming probes recently discovered are just prototypes, in fact, they lack hidden cameras or other methods of capturing bank customer’s PINs at the ATMs.
Krebs sustains that the incidence of such skimming scams will not decrease as more banks begin adopting chip-based payment cards. Most banks and financial institutions will continue to rely on the magnetic stripe to use the new generation of cards. It is likely that banks will continue to use the magnetic stripe at the ATM to check the correct insertion of the card in the slot of the cash machine.
“The principal reason for this is to ensure that customers are putting the card into the slot correctly, as embossed letters and numbers running across odd spots in the card reader can take their toll on the machines over time. As long as the cardholder’s data remains stored on a chip card’s magnetic stripe, thieves will continue building and placing these types of skimmers.” explained Krebs.
How to avoid such kind of attacks?
Users have to avoid using ATMs that may be easier to access from the top-hat, try to use cash machine installed in the wall at a bank and do not use ATMs located in not protected places.
