Experts discovered a new Bluetooth overlay skimmer that interferes with the ability of the terminal to read chip-based cards, forcing the use of the stripe.
The popular investigator Brian Krebs reported the discovery of a new Bluetooth overlay skimmer that interfered with the terminal’s ability to read chip-based cards, forcing the use of the magnetic stripe. The device was found in an unnamed retail chain in the United States.
The PIN pad overlay was designed to capture, store and transmit via Bluetooth payment card data stolen on the stripe along with the PIN provided by the clients on the terminal.
Chip-based payment cards are more difficult to clone, for this reason, crooks forced the use of the magnetic stripe present on the card for backward compatibility. The recently discovered overlay skimmer included a physical component that blocks chip-based transactions on the terminal, forcing the customer to swipe the stripe.
Krebs pointed out that once obtained the payment card data and the PIN, cybercriminals can clone the card and use them to withdraw money at an ATM.
