<p>"Access Everywhere."<br><br>
This year we're thinking about how to make information and services available to everyone. Available wherever you are, whoever you are, and usable no matter how you need to connect.<br><br>
Less walled gardens, more sunlight.<br><br>
You can read the theme story and get some visual inspiration on the <a href="html/defcon-33/dc-33-theme.html">DEF CON 33 Theme and Style Guide page</a>. You can get it in a <a href="https://media.defcon.org/DEF CON 33/DEF CON 33 Theme Doc.pdf">PDF on media.defcon.org</a>. Homework assignments to get you into the vibe coming soon.<br><br>
We can't wait to see where you'll take it.<br><br>
See you at DEF CON!</p>

<p>DEF CON 33 is building steam. Planning is in full swing. In fact, a glance at any nearby calendar will tell you we're already halfway there!<br><br>
We know you need to plan, too. That's why we're opening up Early Bird Online Registration. For the go-getters who register early, weve got our lowest online price. And just like in years past, registering online guarantees your badge, no matter what the attendance numbers turn out to be.<br><br>
Starting Wednesday you'll be able to hit up <a href="https://shop.defcon.org/products/def-con-33-ticket">shop.defcon.org</a> to get your ticket. Are you ready?<br><br>
The Early Reg price is $540 ($520 +$20 processing fee.) Early Bird season ends May 23.<br><br>
Regular Pricing is $560 ($540 + $20 processing) and is available until July 18.<br><br>
Late Pricing is $580 ($560 +$20 processing) from July 19 to the close of Online Registration.<br><br>
As always, online registration is not required. The cash-at-the-door price is just $500, and it comes with the bonus of our world-famous LineCon.<br><br>
We're very excited about how DEF CON 33 is shaping up. We hope you are too.
Past the halfway point, people. Let's GO.</p>

<p class="byline">Posted 2.24.25</p>
<img class="postImageFloat scale-with-grid" src="images/defcon-main/post-images/lawsuit-update.webp" alt="DEF CON legal update" width="300" height="159" loading="lazy" decoding="async"/>
<p>It's been a while since our last update - a lot has been going on behind the scenes - and with the discovery phase complete we have filed a motion for summary judgement asking the court to dismiss his lawsuit. In it we reveal some of the identities of those who testified regarding their experiences with Chris, and I would like to personally thank them for standing up for our community when remaining silent would have been easier.<br>
<br>
The legal standard for evaluating a summary judgement motion means giving the benefit of the doubt to the nonmoving party (Hadnagy) on all disputed facts. Because of this we focused on the undisputed facts, including the documents and deposition testimony, that Chris can't deny.<br><br>
Should this motion fail then we would start preparing for trial, and end up arguing over the disputed facts as well. Both sides will be done with briefing in approximately one month. After briefing is complete we expect the judge to rule on the motion within a couple weeks to a couple months.<br><br>
Thank you everyone for continuing to support DEF CON, and a special thank you to all those who came forward in the ongoing lawsuit.<br><br>
Jeff Moss, President, DEF CON Communications.<br><br>
