Policy matters. The world has never been so connected, and mighty forces contend for the right to shape our digital lives. DEF CON believes the hacker community needs a voice in that process. To help people learn, connect and get involved with the leading edge of tech policy, we offer ‘Policy @ DEF CON’. We’ll have presentations, panels, and off-the-record evening lounges. Get yourself up to speed on the issues, connect with some of the players and maybe even get involved. The future is what we make it!

Let’s GoOOoo!

COVID Updates for DEF CON 30

DEF CON Masked Jack logo image

DEF CON 30 is getting closer, and that means we’re starting to get questions about Covid-19 protocols for the in-person event. Here’s the current state of play.

Some things have changed since DC29. The US has largely stopped checking vaccine status for entry to indoor events, owing at least partly to the knowledge that the vaccines serve more to prevent severe disease than to curtail transmission. COVID-19 testing is now mostly done privately with widely available at-home kits.

But most things haven’t changed. There are still new variants on the move. There are still spikes in transmission and hospitalization. Masks are still the most effective way to protect people in indoor events.

Barring a major change in the situation, we will not check proof of vaccination, but we will keep last year's mask requirement in place for DEF CON 30. Protecting the community is our first priority, and we want to make sure that everyone is as safe as we can make them. Everyone includes the healthy, the vulnerable and those who have immune compromised loved ones they need to protect.

Thank you for all you did to protect each other last year, and with your help we’ll do it again this year.

Training Coming to DEF CON 30, Call for Training is Open!

DEF CON Training logo image

The wait is over - we’re ready to announce the Call for Trainers!

This year we’re adding DEF CON Training – intensive, two-day courses of study aimed at building specific skills. In some cases, these courses will even carry a certification. The Trainings will be held August 15-16, the Monday and Tuesday after DEF CON.

We’re looking for unique, technical, and practical presentations from trainers with deep knowledge of their subject. If that’s you, we’re offering:

- 50/50 split of the gross income.
- Optional test where students demonstrate their skill for a certificate.

All the info you need to apply is on the Call for Training page. Get your applications in early – we look forward to seeing what you’ve got to share.

New Payment Option for DEF CON 30!

DEF CON 30 logo image

DEF CON is a cash-at-the-door kind of conference. Paying in cash helps protect your privacy, and search warrants can't vacuum up PII we don't collect. You will always be able to lay down US dollars in the reg line and collect your badge.

Still, the experience of DC29 taught us a few things. Some of our attendees work DEF CON into their business travel schedule, and the option to pre-reg with a credit card over the web made things much easier for them. Some of our attendees need to manage a group purchase, or want a more detailed receipt.

For everyone who fits into those categories, we’re happy to announce that we’re keeping the option of online registration. Starting Monday, March 28th, you’ll be able to use to buy your ticket and get your receipt. We hope the online option makes the process more streamlined for those who need it. We thank people for their patience and feedback as we navigate the changing landscape.

The price for DEF CON 30 is $360, with a processing fee of $9.66 added to online orders.

Fine print: Currently we cannot provide beachballs and pizza to the online purchasing experience. For that, you’re gonna need LineCon.

DEF CON Movie Night: Dark Star!

DEF CON Movie Night: Dark Star poster image

DEF CON Movie Night this Saturday will feature some more 70s sci-fi with John Carpenter’s ‘Dark Star’ from ’74. Join us 3-19 at 8pm PDT in the #defcon discord ( We’ll be in the movie-night-text channel.

DEF CON 30 logo image

Enter the DEF CON 30 Artwork Contest!

DEF CON 30 THEME image

Now that the DEF CON 30 Theme is out there in the world, it’s time to go pencils up on the DEF CON Art Contest!

This year’s theme is ‘Hacker Homecoming’, and you can read all about it on the DEF CON Forums. It’s a theme meant to celebrate our community’s much awaited reunion next August. It’s also meant to reference the 30th Anniversary we’re celebrating, which is a pretty big deal for a hacker conference.

So if you’ve got some art skills, you’ve got a luxurious 7+ months to get your take on the theme in to us. There’s so much time between now and the June 1 deadline that you could probably learn a brand new art style in which to make your submission. You can drop as many submissions to as you want, so enter early and often.

### Theme:

We are looking for artwork that reflects a spirit of community and reunion. We’re looking for art that combines the 90’s hacker aesthetic of DEF CON’s history and our tribe’s 21st century future. We’re looking for your vision and vibes.

We hope you’ll take in the information in the style guide, but we hope that you’ll use that as a launching pad and not a set of limits. We want to see where you can take these ideas.

### Guidelines:

300 DPI. Convert type to outlines where applicable. Trust your instincts - we’re looking for genuine energy, not technical perfection. We want to share and amplify the artists in our community. If tlhat’s you, get your ideas down. If that’s not you yet, could it be? You’ve got a few months to find out.

Entries will be placed on the DEF CON Forums for voting, and there will be prizes. There will also be gratitude, and opportunities to inspire others with your special way of seeing the world. We can’t wait to see what you’ll make!

DEF CON 30 Theme: Hacker Homecoming

DEF CON 30 THEME image

This has been a crazy couple of years.

A global pandemic turned DEF CON 28 into DEF CON Safe Mode. Some easing of the restrictions and some strict attendance rules gave us a hybrid con for DC29. An improvement, to be sure, but something short of a full DEF CON experience.

We want DEF CON 30 to have the energy of a reunion. We’ll be back togeher in a brand spanking new venue. We’ll be thirty years old - an amazing milestone for a hacker conference under any circumstances. In honor of all that, we’re calling DEF CON 30 ‘Hacker Homecoming’.

The first reason is that it’s literally a return home. After two years of separation, we’re looking forward to having more of our family under one roof, under the Vegas late summer sun.

There’s also a North American tradition called ‘Homecoming’. Secondary schools and colleges invite luminary alums back for a big celebration of the school’s history and a toast to its future. We intend to do just that for DC30. We’ll have some surprise guests from DEF CON’s illustrious past on hand to talk about the amazing places their life has taken them since joining the DC Community. We’ll also be laying out some of the map forward from our 30th Anniversary.

So please join us in the Caesar’s Forums if you can, and on the Discord if you can’t. Maybe even pack a fancy outfit for the homecoming dance. It’s high time for a reunion.

Design Inspiration

This year’s theme is about celebrating the past and getting geeked about the future, so we’re looking for smooth integration of old school hacker stylee with future vibes.

We took the color palette inspiration from arguably the most iconic DEF CON image of all time: the rooftop photo from DEF CON 1.

The photo is amazing for any number of reasons, but the most important is that even though it screams early 90s hacker culture, it also shows some of the essence of what DEF CON is even in the 2020s. It’s still a gathering of extraordinary digital misfits going Voltron in the Vegas night.

The fonts were also selected to be like a homecoming celebration, with some reverence for the past, some excitement about the future. The past is represented by the very 90s CityPop and Geom and the future by the futristic minimalism of Open Sans.


As always, we’ll be sharing movies, books, music and other random media to get you in the right frame of mind for maximum DEF CON. This year we’re even giving you an extra few months to get through the syllabus. Watch the DEF CON site for additions to all the lists. Pencils UP!

The DEF CON 30 Call for Contests and Events is OPEN!

DEF CON 30 CTF call for contest and events image

DEF CON 30 is going to be a big deal, and we’re full speed ahead on planning. If you’ve got a stellar idea for a contest, this is your moment. Take advantage of the early opening to turn your idea into a real DEF CON Experience. The extra lead time helps us work with you to get the best ideas across the finish line, but only if you take advantage and get your submissions in.

You can read the rules and requirements on the Call for Contests Page. You can check the DC29 Contest forum for an idea of what we’ve accepted in the past.

Let’s see what you’ve got percolating out there, DEF CON fam. Let’s take DC30 up a notch.

DEF CON 30: Open and Upcoming Calls

DEF CON 30 Calls image

The DEF CON 30 Call for Villages is already open! To see if your fave is already accepted, check out the Villages forum for DEF CON 30! Don't see what you want on the current list? Maybe that's your cue to submit a proposal!

On the horizon very soon will be the Call for Contests! Polish those proposals for new DEF CON contests now and be ready for the call!

We only turn 30 once. Let's do it big!

DEF CON 30 Call for Villages has Opened!

DEF CON 30 CTF call for villages image

DEF CON 30 may seem a long way off, but it’s never too soon to start planning. Especially for something as close to the heart of the DEF CON experience as Villages.

As always, we’re looking for new villages that will create welcoming, hands-on spaces for congoers to sharpen their skills, learn something new and maybe even find their newest obsession.

Space (both physical and metaphorical) is limited. Early submissions have increased chances of success. If the concept is strong but needs work, we can help but only if we have enough time.

You’ll want to famailiarize yourself with the requirements and submission guidelines at first. If you can meet the preconditions, and you have a stellar idea to propose, that’s the universe telling you it’s go time. Rise to meet your moment.

We can’t wait to see what’s on your mind.

CTF Call for Organizers is Officially Open!

DEF CON 30  CTF call for organizers image

The mighty and venerable Order of the Overflow is retiring from organizing the DEF CON CTF, and the torch must be passed. This means a rare opportunity for you, CTF enthusiasts.

Are you ready to create the next generation of elite CTF tournaments? Do you have the skill and creativity to elevate the game for the world’s best players? The drive to see your ideas through to completion? If this is you, it’s time for us to talk.

The lowdown is at Get familiar, submit the CTF you want to see in the world. For the chosen, glory awaits.
