Assuming that the additional hardening is not relevant, is there any point to using whonix-workstation over, say, a Fedora template with TOR browser installed? All network access should be over TOR as long as whonix-gateway is set as the network VM.
If you use Tor in Fedora, a user mistake or a vulnerability in the Tor browser could allow an attacker send packets outside the Tor browser to a C2, revealing your IP address. These types of attacks don’t happen with Whonix.
This is fair. When I posted it here I was thinking about the topic as “use of Whonix within QubesOS” which seemed on-topic. But thinking about it more, the core of the question is really “what security benefits does Whonix Workstation provide?” which is not on-topic.
I did search the whonix forum but I did not find anything that directly addressed this topic. I did find a tangentially related thread, and included a note about another wiki page which is relevant, in the thread I started on the whonix forum, which I will link to here in case someone else is curious and also searches the wrong forum by mistake.
I would not object to this thread being closed as off-topic.
