mastodon 4.7.3DEF CON is the world's most influential hacker conference. Held every year since 1993 in Las Vegas, Nevada, DEF CON is the hub of a global community of hackers, security geeks and curious technophiles.
DEF CON 34 is wrapping up, and it’s been another amazing year.
Thanks to the amazing DEF CON Community for bringing the good energy, curiosity and enthusiasm that makes this little desert shindig so special. From the old heads who remember why we have a dialer and a floppy disk in our logo to the brandest new newbies, you are an amazing tribe of humans. Thank you for sharing your passions, making connections and looking out for each other.
Special thanks to the army of Goons who make this big machine go. A happening like this takes a lot of skilled and patient hands, and we’re eternally grateful to our top-shelf crew.
It’s gonna be another year until DEF CON 35, but take heart. There are DEF CON Groups you can join to keep the vibes going all year. If there’s not one near you, maybe it’s time to think about starting one. Consider sharing your talent with the DEF CON Franklin Project. Stay engaged. The days will fly by.
We’re already thinking of ways to top this year, and we can’t wait to see what you lovable scamps get up to in the off season.
See you soon, everyone.
OK, who did this.
We caught up with #DEFCON34 Badge Designer Bunnie Huang to get a little background on this year's badge.
It’s not quite over, folks - there is an afterparty. And it’s at the Liv in the extremely swanked out Fontainebleau.
Your badge gets you admission and a free drink. Doors open at 10:30.
See you there.
If there's no afterparty, how can we be sure there was a party at all?
Fortunately, there is an afterparty. And it’s at the Liv in the extremely swanked out Fontainebleau.
Your badge gets you admission and a free drink. Doors open at 10:30 pm.
See you there.
DEF CON 34’s theme is ‘Agency’. We’re focusing on self-determination in our use of tech. Charting our own course and helping others do the same.
Let’s start moving our valuable attention to tech that supports our agency. Let’s find the places we can help and choose to act.

At #DefCon #Singapore next week? End of day one is a community party, end of day 2 is Hacker Jeopardy!
First #defcon34 reading assignment!
As you may know, the DC34 theme is 'Agency'. Wresting self-determination from the machine.
The story 'The Machine Stops' by E.M. Forster contemplated a situation very like our own all the way back in 1909. One year after the introduction of the Model T.
Read, enjoy and share your thoughts.
