Can hackers invade me through wifi? I just want to ask if it is possible. What should I do?

This is entirely possible. After all, you are in the same intranet, and the intranet is very fragile. All kinds of middlemen attack arp, all kinds of deception. If the computer is not diligent in updating, it can also be attacked by loopholes such as overflow! The best way is to change the wifi password in the mobile phone to be a little more complicated, but it doesn't need to be very long, not more than sixteen digits! Hide the ssid and turn it on, then change the password and choose wap2 encryption as the encryption method of wifi! In this way, as long as the password is complicated, it is difficult for others to explode the wifi password in the room! And turn on wireless hiding, others can't see the wifi in the room, so you should join wifi and choose to join the network directly, and fill in the wifi name in the room! Seek adoption
