Yes. There’s no sandboxing in Wine/Proton. It’s just another application running with the privileges of the user running it. So it can do anything any other process could do with that user’s credentials. This is one reason why Wine recommends that you never run it as root.
Comment on What if you tried to run Windows malware on Linux?

There’s still a layer of abstraction there. Since it requires Wine to run, it wouldn’t be able to run itself in the future unless it’s aware that it’s being run in Wine. Then it would need to set up a way to launch itself via Wine.

How the application is started is a separate question. I don’t know enough about Wine to know if it would install a Windows Service as a user service in systemd or init.d or something like that. But if the app is started it can do anything it wants subject to that user’s permissions.

I wiuld guess that if it could, nobody would program it.
The chances of the scenario is too low. Hacking is a numbers game.

Depends of the hacker.
I suppose some government blackhat could do such thing for a very targeted hack. Still unlikely though.

at that point it’d be Linux malware
