From what I’ve read, 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 conference. Fake cell towers do occasionally happen but rapidly lead to arrests.

Why wouldn’t they burn a chipset 0-day? It’s unlikely that only one exploit has been and will ever be uncovered. Imagine the shitstorm if you phoned all of DEFCON with a recording to attend your talk, on their radio “off” devices, because you powered them back on at the right time. Imagine the respect. That would be worth a 0-day.

"random people" who with high probability may have undisclosed 0day exploits stockpiled on other devices.... yeah if I'm an APT author DEFCON attendees are (the hardest to exploit and most paranoid [read: likely to get caught by]) the ideal target for any nation-state. not to mention that the conference is often attended by multiple state agencies which makes the target even juicer. yes it's an extremely hard and dangerous group of people to attempt to exploit, but that doesn't detract from the potential value and payoff of a successful APT exploit on said group of people

That's not how Nation State actors work. One of the things that makes Nation State actors dangerous is they have the patience and resources to attack a high value target at the most likely to succeed point. Backing that up, they generally have the intelligence to know when that best time is. And they for sure know that it's not at defcon when everyone is, as you say, paranoid and on the alert. They're going to get you at home, at happy hour with your non-security friends, in that bar with the great but insecure wifi and no 4g.

Or they'll get you while you're in the security line at the airport on your way home.

I guess it depends which State we're talking about, but yes.

[lawnchair_larry]

You just made that up. There are fake cell stations every year, and there has never been an arrest.

[mortenjorck]

I might be wrong, but I most certainly did not make it up. Will Strafach and Dan Tentler would at least appear to disagree with you: https://twitter.com/chronic/status/884434768380776448

[floatingatoll]

There are no arrests listed for cellular activities at Wikipedia’s “Notable Incidents” list for DEFCON, so if you have direct confirmation of any such arrests, you should add them to the page at https://en.m.wikipedia.org/wiki/DEF_CON

[lawnchair_larry]

You just pasted a conversation full of people saying that there are rogue base stations. And I don't see anyone reporting arrests!

[chinathrow]

I do, if you scroll down a bit:

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.

[willstrafach]

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

> chipset zero-day

The concern is man-in-the-middle attacks. Easy, no user interaction required, and works very well. No chipset zero days involved.
