I had that feeling of taken on Anon-Whonix-ws (more on how the feeling came about at the bottom of the posting).
I installed Bleachbit (sudo apt-get install bleachbit or something like that). I DISCONNECTED the VM from whonix-gw and ran Bleachbit (sudo and normal). What’s the worst it can happen? Maybe delete the AppVM and recreate ir…
To my surprise Qubes 4 RC4 lost all com links between all the VMs to firewall, net and whonix-gw. So much for Compartmentalization…

Just a tip! You better run iptraf-ng in all the VMs you have ON and check the logs ( and that is how you get that special feeling sometimes).
The point is not Bleachbit which I used successfully in 3.2 also. The point is compartmentalization and using Iptraf-ng to see that I was penetrated. People that do SCADA have Ethernet taps with signal analysis. I’m so sick of bull talk and ZERO delivery with quotes from famous people. Things described in these links happen to me every week with Qubes and Whonix!
