The Department of Security has reported that these scams involve victims receiving a text message (SMS) from a sender mimicking the Alcampo ONEY or Alcampo DUA ONEY credit card number. This message simulates an official notification from their bank about a potential large money movement and provides a phone number to supposedly block the transaction.

Upon calling the provided number, there is no immediate response, but the victim subsequently receives a WhatsApp video call from another number. In this call, an individual poses as a bank representative and urgently requests the client's full DNI details, their card's PIN code, and complete card information to block a suspicious money movement.

In some cases, after providing all the details, the scammer asks the victim to download an NFC application to their mobile phone, which allows secure and fast information exchange between two devices, and to place their bank card under the reader to complete the operation.

So far this year, the Ertzaintza is investigating 40 complaints related to fraudulent charges on the Alcampo ONEY card itself, in addition to 11 other scam complaints involving card scanning with an NFC tool, in an effort to identify the perpetrators of these criminal activities.

The Department of Security has issued several preventive recommendations to avoid falling victim to these scams. They emphasized that legitimate banks never request sensitive data by phone or messaging without prior verification. Furthermore, they stressed that the personal PIN code should never be provided by phone, instant messaging, or email, as it is the most crucial key to protect funds and is only requested in physical presence or through secure biometric authentication channels within the official app.
