> all you really need to do is turn off wi-fi, which is already fairly paranoid given that no one is realistically going to burn a serious chipset zero-day on random people at a conferenc

I know very little about security or defcon, but I was under the illusion that stuff like running Wifi Pineapple to trick people to connect to their hotspots was common and doesn't require any 0-days.

There are more advanved tricks which are less overt, but you are correct, none require zero days.
