The car insurance has not yet expired,

I received “greetings” from major insurance companies,

Received a sales call,

The other party is clear about your name, unit, and address,

Talked about something accidentally,

The e-commerce platform will push related products to you;

How did the information leak out?, there are so many ways, if you don’t pay attention, you will get the trick

1. Active disclosure channels may be sharing train tickets, ID photos, etc. on the Internet filling in personal identification information and bank account information in phishing websites and malicious applications connecting to phishing WIFI leads to theft of information, etc.

People with ulterior motives use their positions to query the personal information of citizens in the system and sell them to others.

Hiring others to call the parents’ contact number on the student’s personal information purchased from the Internet, to trick the parents of the student to transfer money through the ATM machine to obtain money from it.

Someone asked, what is the picture of such a deliberate attempt to steal personal information?

Some people think that it’s just leaking some personal information, what are they afraid of?

You may not know, the harm is greater than you think!
