Anything and anybody at any time of course can be hacked.
But why make it, relatively speaking, easier even if chances of it happening are slim?
Well I guess everyone has WiFi at home these days, so even when your trading devices are connected via ethernet they could still hack any device in your network, even the ones connected via ethernet if hackers gained access to your network via your WiFi since most WiFi routers these days also have ethernet ports which most people use to connect their wired devices to.
Even when they are not connected to the same router, it's harder, but certainly not impossible.
I'm of the view that work is work so desk and consistent environment without distractions. When I'm in my office my family know to message me, not just drop in. I have a glass door, not up to anything weird
