How did harassing calls and spam messages find our phone number?

All kinds of registration information Although the harassing calls we all receive are annoying, they are not terrible. However, it's a little scary if all these harassing calls you receive are named! Who leaked our information? In fact, most of them were leaked when you registered various websites or filled in various information!

Personal Authorized Account Now more and more websites can use QQ, WeChat, Weibo and so on. It is good news for lazy people to log in to a third-party account, but such arbitrary authorization will greatly increase the risk of privacy leakage. We all have real-name authentication for these accounts, but there are so many authorized accounts that I really can't remember what they are. To avoid information leakage, we should start from the source.

First of all, when using your mobile phone number and email address to register, you should decide whether to use your usual number or work number according to the situation. Generally speaking, for some applications with low security, it is recommended that you use small registration. So, what about people who don't have two cards? Today, the three major operators and joint services have launched many Internet numbers, some of which can be used without physical cards.

These numbers can also make calls, send and receive short messages, and naturally you can register to receive verification codes. Whether it's email or other accounts, our passwords should be set a little more complicated and changed frequently. More importantly, try not to use the same password for every account, so as not to leak one place and everywhere! If you want to be less targeted by harassing calls, you must protect your information!
