I sought out a new ‘developer’ OS after my Qubes system was destroyed by an attacker (ROP sigkill VM-s, qubesd and d-bus – I shared drive links to screenshots of these events if anyone is curious). Perhaps an expert looking at the slides (that is another good use for sandboxing if mistrustful) would be able to tell what sort of vulnerability caused the crashes.
