Be very careful if you receive an SMS from the number 663475590

Since this Monday, several dozen users have publicly denounced the receipt of an SMS through the number 663475590. The text message says that our Banco Santander bank account has been deactivated for security reasons. From now on we can confirm that it is a fake SMS. But what is behind these types of messages? And most importantly, what can we do if we have fallen for the scam? We see it below.

SMS from 663475590, who is it?

"I have received a message from the number 663 475 590 saying that my bank account has been disabled", "I get a disabled user for security reasons", "I have called my bank and they have confirmed that everything is fine"… These are some of the testimonies that we have been able to find around the number 663 47 55 90. What is really behind these SMS?

The truth is that it is a phishing attempt. The message in question contains a link to a web page that mimics the appearance of our bank's access panel. After entering the bank details in the web form, the information is sent to the thieves.

Later this information is used to impersonate our identity and make bank statements and transfers to other account numbers. It is something that has been confirmed by the different banking entities and that affects several banks in Spain, including Banco Santander, Bankia, Banco Sabadell and even BBVA.

What happens if I have entered the data on the web

To avoid any unauthorized operation we will have to immediately contact the customer service of our bank to block the banking operations. We leave you below with some active support numbers 24 hours a day, 365 days a year.

• Banco Santander customer service number: 915 123 123 (national rate).
• Banco Sabadell customer service number: 935 20 29 10 (national rate).
• Bankia customer service number: 916 02 46 80 (national rate).
• BBVA customer service number: 912 24 94 26 (national rate).

Once we have contacted our bank, it is most likely that some type of personal information will be required or even that we will appear before an office to corroborate that we are the owners of the account. We also recommend changing the passwords to the bank's panel through the platform options.
