As you’ve likely heard, attendees in the cash line are getting paper badges right now. This is due to a badge shipment delay. We’re sorry for the inconvenience.

DEF CON started in Las Vegas, but we've become global with people attending from all over the world and there are local DEF CON Groups on 6 continents.

Hard as it may be to believe, the Snowden revelations are over 7 years old. The news cycle has accelerated so much in the intervening years that it seems like a relic from a different age, a slower timeline where a big story could make headlines for weeks instead of getting buried by four equally unsettling headlines before dinnertime. Wherever you stand on the ethics of the disclosure, this glimpse at the scope of the US domestic surveillance apparatus has had enormous impact on the way the public views its privacy. In the last few weeks, Snowden's name has been in the news again as he accep…

The Most Dangerous Game' was made in 1932, but you can still hear its echoes in modern cinema. It's a surprisingly tense pre-code thriller about bored rich creeps who hunt humans for sport, and it walked so 'Predator' could run. Good fun, and a subtext that finds its way into movies a lot more often than you think. Watch this space for some more discussion of the film and join us in the DEF CON Discord Server Saturday Night at 8pm PST ( discord.gg/defcon /) in movie-night-text and movie-night-voice.

This week, we are going to continue the simul-tubing experiment with 'IT! The Terror from Beyond Space" - a solid sci-fi thriller from 1958 that's one of the main inspirations for 'Alien'. In case it isn't readable, that movie poster promises $50,000 to anyone who can prove the creature from the movie is NOT on Mars. You gotta respect a film that stands behind its premise.

#defconmovienight update for November 21 Next week's movie will be the classic 80s hacker film 'War Games'. "But how? Don't the terms and conditions at discord forbid sharing copyrighted content?" Fair question. If we showed the movie in discord, we could run into issues. However, 'War Games' is showing for free on YouTube, praised be the internets. So the plan is to make it a double header. For the first hour, we'll show a talk from DEF CON 16 where The Dark Tangent interviews David Scott Lewis, engineer, consultant and the model for the David Lightman character in War Games.

In honor of the five new states that legalized marijuana in this week's US elections, DEF CON Movie Night is showing the original 'Reefer Madness'. First released in1936, this anti-marijuana propaganda piece began as a church-funded film called 'Tell Your Children'. Designed to scare kids away from 'jazz cigarettes', the plot revolves wide-eyed teens lurching from innocence to utter depravity after a brief dalliance with what was likely some very weak-sauce Depression-era weed. Unintentional hilarity follows. The filmmakers overplay their hand to such an extent that the film probably encourag…
