A Chinese netizen recently took to the technical social media “V2EX” to reveal how he found that his TV at home could automatically scan all network devices and automatically send back data.
The user said that because he thought the TV was slow, he opened the system to see what features were turned on and found a feature called “hook up data service”, “I have no idea what it does”.
So the netizen studied, and found that this thing every 10 minutes will scan through all the devices connected to his home network, and automatically pass the data to the designated website, “the hostname, mac, ip and even network latency time all back, but also detect the surrounding wifi SSID name, mac address is also packaged to pass This gz-data.com domain”.
Netizens asked: “That is, what smart devices at home, cell phones at home or not, who came home to connect to the Internet, what is the name of the surrounding neighbors wifi, at any time to collect and upload, sure this is not a spy service?”
The netizen also revealed that his home TV is Skyworth, using the Android system.
Under the article netizens have left messages expressing concern. Some said they were also frightened, but also asked for advice on the technical details of.
