Is it dangerous to be bombed by verification code?

"If you receive such harassing text messages, don't reply and don't worry about the security of your mobile banking account." The operator staff said that if the verification code information sent by the normal website is suddenly received in a short time, personal information is less likely to be stolen and more vulnerable to personal attacks.

According to the operator's understanding, the harassment of SMS verification code is mostly caused by users' related operations on the network, such as online shopping, taxi and other disputes. In order to retaliate against the owner, the other party uses malicious network bombing software to harass user information.

The principle of verification code bombing:

The bombing of SMS verification code is generally based on web, which mainly consists of two modules: the front-end web page provides an input window for inputting the mobile phone number of the attacked person; A background attack page (such as PHP) sends an HTTP request by using the dynamic short message URL found from various websites and the attacked mobile phone number input by the front end, and sends a dynamic short message to the user every time.
