DEF CON 29 logo image

The past few years have been crazy, but you can’t stop the signal, even with global cataclysm. We are so happy to be reunited with so many of our friends, both here in Las Vegas and in the virtual con space. It’s good to be together.

Thank you for your support through everything. Your unending enthusiasm sustains our work and the DEF CON community never disappoints. Thanks for following the stricter rules the pandemic made necessary. Thanks for being kind and patient with each other and with us as we navigate the swiftly changing landscape.

Next year is a big anniversary for DEF CON, and we’re already at work planning how to make the big 3-0 memorable. Here’s to next year reuniting even more of us.

In the meantime, keep in touch with us on the DEF CON Discord server. Join a local DC Group, or start one. Stay safe and healthy. DEF CON hearts you.

DEF CON 29 press roundup image

We’d like to shout out newly minted Photogoon Alex Chaveriat aka ‘Silk’ who spent his DEF CON 29 racing around the con floor finding cool projects to interview people about. If you follow the DC social media feeds you’ve probably seen some of his work this year. Thanks to everyone who gave him some time, and thanks to Alex for putting out so much quality stuff so quickly. Alex Chaveriat on YouTube

The moment has arrived! You can reserve your badge for DEF CON in Vegas or the DEF CON online-only event right now at Your pre-purchase allows us to accurately predict attendance, and it guarantees you a physical badge and secures your space if the venue is forced to restrict capacity. We thank you for your support and flexibility – hard numbers are the only way we can responsibly make a physical DEF CON happen this year.

Cash at the door will still be honored for as long as spaces last, but there is a chance we’ll have to turn away cash customers if we reach capacity for our venues.

For everyone who can’t be with us in person, the Safe Mode option continues over on Discord and we expect to start mailing out badges in early July.

We’ve got an FAQ page for all of your questions, and you can always get in touch with us at Thank you again for the support - we can’t wait for August 5!

Update! Pricing Chart:

DEF CON 29: The Plan So Far

DEF CON 29 pixel con image

I am announcing this now because the longer we wait and gather data the harder it will be for everyone to make plans, so we are announcing our intentions to kick things off.

DEF CON 29 will be a hybrid conference, partially in-person, and partially online. DEF CON will not be a “normal” con, but more like DEF CON “Different.” The situation we face this year is unique and will require us to do things differently, simplify our plans, and in a fast-moving environment be flexible to change.

DEF CON 29 Theme and Artwork Contest!

DEF CON 29 theme image

It’s official. DEF CON season has arrived. DEF CON 29 will be happening this August in one form or another and that means it’s time to announce the theme!

The theme for DEF CON 29 is (imagine a drum roll here) ‘You Can’t Stop the Signal’.

The signal can be a few things. It’s the powerful force that draws DEF CON together as a community, across miles, across years, even in global lockdown. It can be the magnet that draws us to the people trying to solve the same puzzles we are, who want to learn how everything works as much as we do. And it’s how we instinctively know that the technology we live with can be better, and we are the ones to figure out how.

We’ve put together a style guide that lays out a bunch of our inspirations for this year, from visual aesthetic to music, to movies and books. We hope it inspires you in whatever you’re creating for DC29, and we hope it gives you the same powerful sense of community and possibility that we feel.

The style guide also governs the Art Contest, so if you're artistically inclined we hope you'll find a nugget or two in there to inspire your entries. We look forward to seeing what you come up with and we thank you for being the kind of amazing, unstoppable community that keeps us coming back.

DEF CON 29 Call for Everything!

DEF CON 29 Call for Everything image

DEF CON 29 approaches. It looms. Darn near impends. Be still, and you can hear it – the DEF CON Call for Everything ringing though the air.

The CfE is when DEF CON throws open the doors and invites everyone’s best proposals in for a visit. Speaking proposals, ideas for vilages, prospective demo labs, contests, trainings, music, art - literally everything. You write up all the delightful things you want to share with the community, and we find a way to bring the best of them to life at DEF CON.

The Call for Everything page lists all the ways you can participate in the creation of the next DEF CON, along with the relevant details and deadlines, including some new questions intended to get your thoughts on whether this year’s con should be in-person, online or some of both.

So visit the CfE page, read the guidelines, and get your best ideas together. Let’s DO this thing!
