I'm just curious as I've permanently dedicated my laptop to torrenting. I've been too nervous to install anything but the VPN and Firefox on it. Now, I'm curious to mess around with Linux some more, which is what I use on it, but I can't fully test out what all I can do with it without signing into accounts.
Do you use your torrent machine to do other things besides torrenting, signing into personal accounts and stuff?
Security starts first with you. Most of the attacks are done though social engineering. Email phishing, dodgy webpage logins. Normal password security behaviour should fine for you to use the pc. More importantly, what is the distro you're using? Maybe consider using Flatpaks for the apps, they tend to offer more restrictions on access to the system. (Installing the torrent app as a Flatpak and only give it permissions to a specific folder) One of things I tend to do is install chromium just to login on my Google apps, Gmail, YT. But I'm more of a non data sharing freak.
