Unfortunately I haven't seen any serious effort in the security world to address most of those threats. We still don't have any effective way to combat type II malware. Network intrusion detection systems and firewalls are years behind when it comes to detecting or preventing any more advanced covert channels. We still don't have any good solution to prevent or detect hardware virtualization based malware...
I would like to work more on the defense side now - I believe that we should convince OS vendors (and also CPU vendors) to make systems verifiable - so that we could come up with *systematic* ways to check whether the system is infected by any of type I, II or III malware.
