From New Year to WiFi Sharing
The night before the holiday was taken off home, the network of the TV box at home was abnormally poor, and the picture was a meal. I opened the router management interface and found that there were two more wireless devices in vain, greedily preempting network traffic.
I am very puzzled: I just changed a complicated WiFi password last week. Why is it so fast? After some pondering, I downloaded and opened a well-known WiFi sharing software and found a key icon behind my WiFi. This key means that the WiFi password has been shared.
A few days later, I found that many of my relatives' WiFi can connect directly with this WiFi sharing software. Obviously their WiFi password was shared with the platform. In the end, I found the "culprit" of the WiFi password leak - just the middle of the junior high school. Every time he visited a relative, he called for a WiFi password, and then the cat played in a corner to play mobile games. Even he did not expect that he was "actively sharing" the WiFi of others.
A round of relatives came down. When I went to the relatives' house, I followed the scorpion and didn't have to ask the WiFi password. The little scorpion had already "helped me to get there."
Interestingly, when I was visiting my aunt's house, there were only five or six people in my family. I opened the router management interface of her home and found that there are 19 wireless connected devices. I have counted the connected devices in the house. How can I not exceed 8? One. When I looked out the window, I found that there was a vegetable market not far away - it was.
From WiFi sharing to control router
Some readers have noticed that I can easily enter the router management interface of my aunt's home. The reason is simple, because her home router did not change the default password, which is the second topic of this article. —— After visiting a circle of relatives and friends, I found that more than 80% of the home routers are in the streaking state, some are “full naked†and some are “semi-nakedâ€.
The so-called "all-naked" refers to the default password of the router using "admin", "password", and empty password. "Semi-naked" refers to "123456", "12345678" and other weak passwords that are easily cracked, or the password is the same as the WiFi password, so that I can directly take over the router of the other party with the skills that the primary school students can master. The default account passwords managed by various routers can be found online.

Rising Security has issued a report that 70% of home routers lack security protection. The report at that time was based on sample data from domestic first- and second-tier cities such as Beishangguang. After a round of relatives came down, I found that compared to first- and second-tier cities, the safety of routers in small cities, especially in rural areas, is even more worrying.
For many families in small cities, it is normal to not change the router password. The router management login address is also the default. (Generally 192.168.1.1 or 192.168.0.1), most people rarely enter their own router management address, and even many people do not know the existence of the router management interface.
