Chris Hadnagy vs. DEF CON Lawsuit update

----------------------------------------

](https://storage.courtlistener.com/recap/gov.uscourts.wawd.329575/gov.uscourts.wawd.329575.84.0.pdf)

Posted 2.24.25

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.  

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.  

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.  

Thank you everyone for continuing to support DEF CON, and a special thank you to all those who came forward in the ongoing lawsuit.  

Jeff Moss, President, DEF CON Communications.

Good news, everyone! We’ve already got some discounted room blocks you can use to lock down your lodgings for DEF CON 33.  

DC33 doesn’t kick off until August 7, 2025, but that’s no reason to lollygag. If you’re a high-octane go-getter you already know how good it feels to get those To-Do items checked off early. If not, this is far enough ahead to forget you booked and give yourself a nice surprise when there’s one less thing to do at crunch time.  

You can book at the [Venetian](https://book.passkey.com/go/RDCON) now and get the DC33 ball rolling. We’ll keep you posted as additional options become available.

Thanks for a Great DEF CON!

---------------------------

Posted 8.11.24

DEF CON 32 has wound down, and we want to thank our community for making this one stellar. You never fail to bring gigantic love and enthusiasm to every aspect of the Con, and we are inspired by your example.  

The curveball of a sudden, late-stage venue scramble could have spelled disaster, but it turned out to be a blessing in disguise. Having so much of the Con back under one roof felt great! FIrst years in a new venue always mean some hiccups and learning experiences, but you reacted with patience and grace when they happened. For this you have our eternal gratitude.  

As always, if you want to keep that DEF CON feeling alive in the off-season, you can and should join a DEF CON Group in your area. If you can’t find one, we encourage you to start one ([https://defcongroups.org](https://defcongroups.org)). We also encourage you to check out our new project DEF CON Franklin ([https://defconfranklin.github.io](https://defconfranklin.github.io)) to find ways to put your skills to work where you live.  

As you return to your real lives, share your engagement ideas with us at [https://defcon.social](https://defcon.social) and we’ll amplify. Let’s motivate and encourage each other. Let’s stay engaged, with each other and the wider world.  

We’ll see you again just one short year from now in this same charming little place. In the meantime, keep learning and making new stuff, and look out for each other.

DEF CON Response to Badge Controversy

-------------------------------------

Posted 8.10.24

DEF CON thrives on community collaboration and has operated for over 30 years successfully working with hundreds of vendors including the dozens that have helped with our badges over the years. For this year’s Raspberry Pi badges, DEF CON hired Entropic Engineering to do the hardware development and firmware. After going overbudget by more than 60%, several bad-faith charges, and with a product still in preproduction, DEF CON issued a stop work order. Any claims that DEF CON did not pay Entropic Engineering for its hardware or firmware development are false. Unfortunately, we heard that these issues with Entropic Engineering were not unique to DEF CON. We decided at that point to finish the badge on our own. We paid to send engineers to Vietnam to work onsite to finalize and test the badges in order to ensure they would be done on time for the conference. We never removed Entropic Engineering’s logo from our badge, it is still on the PCB. However, Entropic was not involved in the design and production of the case, and we removed their logo we had added as a courtesy.  

We were happy to still include one of their contractors on the badge panel session. Unfortunately, shortly before the talk was set to take place DEF CON became aware that unauthorized code had been included in the firmware we had paid Entropic Engineering to produce, claiming credit for the whole badge and promoting their coin wallet to solicit money from DEF CON attendees above and beyond what we had negotiated. When asked about the unauthorized code, the engineer said it had been done as a “joke” two months ago and forgot to remove it, and we decided as an organization not to have him on stage while we kept the slides in the talk giving him credit for his work. We communicated the change in advance of the talk, and this individual decided to show up for the panel anyway. He refused to leave, demanding that our security team remove him. Wanting to ensure that the other people involved in creating the badge were able to deliver their presentation, we complied with his wishes and escorted him off the stage, where he was free to continue attending the conference.  

Any issues of non-payment are between him and Entropic Engineering, DEF CON fulfilled its financial obligations.

DEF CON 32 #protip: On the desert planet of Las Vegas, door to door AC is worth its weight in water.  

When choosing a hotel, don’t overlook our deeply discounted room block in the Rio. All our reserved Rio rooms are fully remodeled suites, and there’s a FREE shuttle right to DEF CON’s main entrance. No wasting your precious moisture on the burning sidewalks.  

Also, we have it on good authority the the shuttle moves without rhythm so as not to attract the worm.  

[Check out the Rio room link now!](https://book.passkey.com/gt/219994873?gtid=61fe6fbb382f8c0f53f21fea47821433)

Another new room block - The RIO!

---------------------------------

Posted 4.22.24

We’ve secured a [block of deeply discounted rooms at the fabulous Rio](https://book.passkey.com/gt/219994873?gtid=61fe6fbb382f8c0f53f21fea47821433), with FREE shuttle service to and from the West Hall of the Las Vegas Convention Center! In addition to the door-to-door shuttle service, they’re giving us a big break on the room rate AND the Resort Fee. Rio also offers [additional discounts for government employees](https://book.passkey.com/gt/219994888?gtid=8024fa5af2024b9e294865eb034b9017)  

We love the Rio - it was home base for DEF CONs 19-22 - and you should see it now. It’s had a massive multi-year renovation and it’s new all over. New all-suites accomodations, new restaurants, new food hall, even a redesigned 5-acre pool complex. It’s a whole new experience at a steal of a price.  

We expect these to fill quickly, so you should act accordingly and book now!

New Room Block! Resorts World!

------------------------------

](https://book.passkey.com/e/50812150)

Posted 4.6.24

Spring has sprung. That means laughter in the air, flowers everywhere, and DEF CON right around the corner. In the spirit of new growth we’ve got another discounted room block for DEF CON 32 attendees - this time it’s at Resorts World. You can check the selection and [book at this link](https://book.passkey.com/e/50812150).  

Resorts World is the very large, very new hotel-casino complex that sits on the lot once occupied by The Stardust. It sports a location convenient to the LVCC, the very latest in accommodations and (so far as we can tell) no relation to Michael Crichton’s WestWorld and FutureWorld.  

It’s all happening, people. Just a few more months till the big event. Prepare accordingly.
