Quote:The US Secret Service has issued a warning to banks due to a recent surge in incidents of ATM wiretapping.

According to a copy of the notice secured by Krebs on Security, the non-public alert states that multiple reports have been received relating to the ATM hacking tactic.

ATM wiretapping or eavesdropping is more complicated than many other attacks. In order to be successful, a criminal must drill a large hole in a cash machine and use a combination of magnets and devices to attach a skimmer directly to the ATM card reader.

This skimmer then harvests credit card information. The hole is concealed with metal or a decal, and cameras are also embedded to capture PIN number input. They are often installed directly above a PIN card and disguised with a false fascia.
