Today, I received a short message from CCB, saying that I have reached 5000, and I can return 10% 500 yuan and log in to my account online.

You received a short message from CCB saying that you can convert your points into cash at the interest rate of 5%, and there is a website for conversion. That's a fake. Weibo of the news media said it many times, and it was also published on the credit card website of CCB. I also received their reminder message. This redemption message was not sent by CCB, but a message released by a liar with a pseudo base station. Pseudo base stations can send information with any number. Today they can pretend to be CCB and tomorrow they can pretend to be ICBC. This is not a system loophole of CCB, but a new fraud. Moreover, the URL on this short message is not CCB's, but a so-called phishing website. Now that you have entered the card information, in fact, the scammers know it, and they will pay online. Fortunately, you haven't entered the SMS verification code yet. If you enter it, it is equivalent to telling the other party to let them pay online aboveboard. Moreover, the bank is not responsible for the theft caused by your own disclosure of card information. You have to contact the merchant yourself to handle it.

In this case, it is useless for you to just change the password, because your card information liar already knows. So you should contact the CCB credit card customer service hotline as soon as possible, and then tell them about this situation to see if there is any stolen transaction (if you don't tell the other party the SMS verification code, it should not be stolen). In addition, it is safe to get a new card. After receiving such news, you must confirm with the bank in time. Don't be casual.
