My grandfather is interested in buying a smart tablet. He never had any personal computer or any internet connection. He wants to use his tablet solely to read the newspaper, as they no longer deliver in his area. He intends to download the latest issue of the newspaper by walking close to our house, temporarily connect to our internet, download the issue, and head back to his home, where he doesn't have internet.
Some members of my family claim that he does not need to install any OS update, because he connects to the internet for a small amount of time, and because in the event that he catches a virus, he doesn't have any data that could be stolen by ransomware.
What are the risks of connecting a device that did not receive any security update to the internet for a small amount of time every once in a while? Should I worry? What should I tell my family?
