The passenger car verification code issued this morning 106575000369 is signed by the passenger car indicator office. What the hell does this mean? Hacked or cheated?

On February 23rd, 65438, official website, the city's passenger car index control management office issued a notice saying: (Recently, the passenger car index management information system sent "SMS verification code" information to some passenger car index applicants, which is a service function of the system and has no influence on the lottery applicants. But I personally think this is an attack on the passenger car index website. Hackers use the "click to get SMS verification code" in the "retrieve password" function to attack websites, resulting in a large number of users receiving verification code messages. So far, the website "Click to get SMS verification code" has not been used normally.
