How to impersonate the official customer service of the bank to send fraudulent short messages?

Bank anti-fraud experts said that this new type of telecom fraud mainly uses the cardholder's psychology of caring about credit information. Fraudsters establish initial contact with users by sending short messages, guide users to obtain information step by step, and then commit fraud in the name of cleaning up bad credit information or unfreezing credit cards. But you don't have to be too nervous. The best way to deal with this situation is to ignore unofficial phone calls and don't click on links in text messages at will. These links are likely to obtain customers' personal information. At the same time, don't call back directly in SMS, and don't tell others personal privacy information easily.
