A woman in Nanjing was maliciously harassed for sending a video of finding things. What network security problems have you encountered?

A woman lost her mobile phone, so she posted a searching for you on the Internet with her contact information. Soon, a man contacted the woman and said that he had found the mobile phone, but the condition was to meet some improper requirements. The woman was so angry that she ignored it. Subsequently, the man added the woman's WeChat and kept sending various harassing text messages. The woman also thought that he really found his mobile phone, so she asked the model and color of the mobile phone seriously. Unexpectedly, the man could not answer anything and continued to harass the content. At this time, the woman felt that she had been cheated and called the police.

This matter was published by the People's Procuratorate on the Internet. Everyone remembered the network security problems they had encountered, saying that they had been harassed by others and even cheated by others. Now they are still scared when they think about it. Moreover, after I saw this news, I also remembered the network security incident that I had encountered, which still makes me nervous.

First, when I was in college, I opened QQ in the morning and suddenly found that many students reminded me that my QQ had been stolen, and I borrowed a lot of money from them, and they also discussed it with me in the group. I carefully read the chat record and found that my QQ account did borrow money from others, and there was a language conflict with others. I checked the login address and time of QQ account, and found that someone did log on to my QQ in a different place and asked my relatives, friends and classmates to borrow money. After discovering this problem, I immediately revised the QQ password and set up a higher level of security protection.

Second, when I had a verbal dispute with others about an event on the Internet, I expressed a different view from the public, but I was besieged by many netizens. Some netizens just argued with me and refuted me reasonably, but some netizens began to scold me. Some netizens even sent me private photos, which I have already published on the Internet and deleted. I don't know how the other party found my private photo and sent a message. Is this you? ? Obviously, he has been able to hack into my software account and get some basic information about me.
