Now in a big shopping mall or restaurant, you will always see some free WIFI. I was always connected. But recently, when I heard that this might be a hacker's trap, I began to worry a bit about the security of my smart devices. How can I avoid accessing suspicious WIFI?
In general, your device is safe if you can block nearby WIFI signals. At present, the network security center has developed a new type of WIFI jammer. The device blocks nearby WIFI and bluetooth signals, making it impossible for hackers to break into your device
