Chile warns banks customers about vishing

Banks in Chile have issued an alert over rising vishing, a scam in which criminals call users while posing as executives, tech support staff, or even police officers to steal passwords and transfer credentials.

What banks are warning about

The warning, reported by El Mostrador, focuses on calls in which the supposed operator tries to get the victim to share sensitive data or approve transactions while staying on the line. Under Chilean security rules, no bank in the country should ask by phone for secret keys, transfer passwords, coordinate card codes, or confirmation of transactions in the mobile app while the customer is speaking with the supposed executive.

The fraud works by exploiting the trust that comes with what sounds like a legitimate call, then pushing the user to hand over information in real time that can be used to empty accounts or make unauthorized use of financial instruments.

Official response and legal framework

At the same time, the Government of Chile, through the Undersecretariat for Crime Prevention, is designing a specific education plan against vishing and other phone scams. The initiative is based on data from the National Citizen Security Survey, Enusc, and is aimed at a national campaign similar to the one used for blocking cell phones, with the goal of addressing phone and digital fraud.

In the same official context, authorities reiterated that victims should immediately contact their bank's 24/7 emergency channels to block payment methods, file the formal report with the financial institution, and then report the case to Carabineros or the PDI.

Chile's National Congress Library, meanwhile, maintains a legal guide on theft and fraud involving the use of cards and financial instruments. That material penalizes the fraudulent use of payment cards and electronic transactions, and says institutions must report every six months the number of affected users, the amounts involved, and response times.

The combination of bank alerts, response rules, and legal guidance shows that the focus in Chile is now on stopping the scam before the victim hands over credentials or authorizes a transaction from their own device.
