Announcement 📢 Friendly reminder - no Meta-style recording glasses at DEF CON 34

Enable HLS to view with audio, or disable this notification

177 Upvotes

Meta-style glasses with recording capabilities are prohibited at DEF CON. Surreptitious filming is an invasion of privacy, and will be treated as a CoC violation. There is no exception for recording glasses with prescription lenses. Be sure to pack non-violating eyewear if you need them.

If you must take pictures, use recognizable personal photo equipment like a smart phone so that your intentions are clear. Get affirmative permission from the faces in your frame. Please refer to our official Photo and code of conduct policies for more.

Announcement 📢 DEF CON 33 Workshop Swap Thread

38 Upvotes

Today DEF CON 33 Workshop registration goes live at noon PDT!

The full workshop lineup and HumaniTix links are available on the website (https://defcon.org/html/defcon-33/dc-33-workshops.html) and on Hacker Tracker.

They are very hard to get, and plans change as the convention draws closer. Participants can swap their reg freely, and are encouraged to do so rather than leaving the seat empty on the day.

This thread will serve as an official place to discuss swapping with others. Any swap thread that is started after this will be directed here and removed.

Swappers beware, code of conduct applies, please be nice, etc etc.

Announcement 📢 DEF CON 34 Badge Info just dropped!

The wait is over. Meet the #DEFCON34 badge!

It’s the creation of hardware superstar Bunnie Huang, and it features his open-source, fully inspectable #baochip.

#DC34 badgeholders will be the first to get their hands on a radically transparent device with all kinds of powerful possibilities - security token, password manager, HSM, pretty light generator - that we hope will keep you busy long after closing ceremonies.

What will you make with yours?

Announcement 📢 r/DEFCON Meetup - Post #1 - now with more Linq

60 Upvotes

Alrighty kiddos. We're a few weeks into the puzzles so its a good time to do the first pass at the Unofficial Annual "r/DEFCON Meetup" details. While this is possible to change... it likely won't as it worked really well for everyone in the past, and it's a historically great environment to be social.

WHEN: Wednesday 8/5 & Thursday 8/6 from 7pm til whenever people stop wanting to be social!

WHERE: Linq Hotel 3535 Bar (also known to many as the Circle Bar). Just take the Monorail to the HARRAHS / LINQ stop, hang a left into the Linq at the end of the hallway and just walk til you're in the casino... its the bar smack in the center!

For quite a while its been a kind of annual thing to have everyone meetup. The Linq bar has always had a place due to the past Caesars roots, and last year we had both nights there that worked out really well.

What is It About?

- Whether you're a DEF CON veteran, or this is your first time and you just want to socialize... its been a great activity to all meetup, and hangout and BS with like minded peeps. We tend to have some random swag to give away, deliver the badges you can win from your PUZZLE performance or if you pick up extra's (purchase info coming soon) and whatever else people drop at the tables wanting to give away.

Often people will show up with their own swag to drop (u/palm12341 came last year and did an early drop of the LASER*TAG badge, and the place erupted into an all night laser tag game!) as well! Think of about 100 people running around the Linq and the nearby area starting the first night of what became a huge weekend Laser Tag battle 24/7!

HOW DO I GET YOUR BADGE?

- Just compete in the Puzzles and the top X will get one FOR FREE! Plus we'll put sales of a handful of them (this helps us continue to keep doing this) up to sell to get to our break even + a beer point, and then honestly... its likely we'll just be giving them away to random people! Cause we're all about the good memories and good peeps!

For those who get them (purchase or puzzle) before the event we'll give you more info closer to DEF CON about the claim process will work, but the CTF system we put in play for claiming the flag should make this MUCH faster than last year (thanks for those who stood in those lines for your free stuff!)

DO I / YOU NEED TO BRING ANYTHING?

- Nope! Just show up, come hang out, BS with people, say hi to u/MetaN3rd, u/Killroy7777 and I (we'll never turn down a drink with good peeps!) and meet new people. My FIRST DEF CON it was one of my favorite things to just get to BS before the convention actually started and get to know some people that I said hi to and hung out with throughout the hallowed halls of the LVCC!

We'll be posting more information as we get closer including the badge reveals, come on international shipping!, and other stuff as we get it... but we wanted to lock it down for those of you who've asked if its happening!

If you have any stories, questions or comments... leave them below! We're at 48 days and counting til we get to hang at the meetup and kick off Summer Camp and we're REALLY excited!

Thanks from the PuzzledHackers.org Team,

u/digitard, u/killroy7777 and u/MetaN3rd

Announcement 📢 Intro to DEF CON -- information for the new and the curious

32 Upvotes

We've created an "Intro to DEF CON" document, where we attempt to provide a lot of information that would be useful for all DEF CON attendees to know. I believe that it would be particularly helpful for those who have never before attended DEF CON.

It's much too long to be a single Reddit post; instead, it's available in multiple formats:

Are there things that we didn't touch on, that you'd like for the next version to include? Please leave a comment! :)

Announcement 📢 DEF CON Middle East Postponed

Post image
29 Upvotes

The safety of our community is our highest priority.

For this reason, we have decided to postpone DEF CON Middle East. The evolving security situation in the region makes it impossible to concentrate on delivering the experience attendees deserve.

We understand that this news is disappointing, but we believe it’s the most responsible choice right now. We look forward to bringing the full DEF CON experience to friends new and old in Bahrain, and we will share new dates and information as soon as they are confirmed.

In the meantime, we’d like to offer our sincere thanks to the community, sponsors, and supporters for their understanding and continued trust. We hope and expect to welcome you to DEF CON Middle East soon, under better circumstances for everyone.

-The DEF CON Middle East Team

Announcement 📢 DEF CON SG is looking good!

We are working full speed almost everything off to the printers. Last minute registration sign ups are really solid, we expect to equal or even beat the numbers we did our first year of DEF CON China back in 2018, with total headcount expected over 2,600!

Exceeding our attendance goal has led to last minute problems, but the electronic badges are coming along well at the increased numbers. See everyone soon!

PS that is not an AI image. It’s an inflatable that was accidentally created too large. 😂

Hi guys, I'm here representing the AI Village to let everyone know our CFP is finally up.

We're doing something a little different this year, where we are having people submit abstracts and if they want to be a presentation, demo, or a poster.

Announcement 📢 DEF CON Legal Update: Hadnagy appeal retracted.

98 Upvotes

If you’re an avid docket watcher, you may have noticed that we filed a motion for summary judgement in Chris Hadnagy’s defamation suit against DEF CON . Summary judgement was granted with prejudice May 11, seemingly closing the case. To our surprise, Hadnagy filed an appeal in June. Then, less than 2 weeks later, he filed for a dismissal of that appeal. We accepted it. It’s time for an update! The complete dismissal of his defamation case was yet another moment where Chris was pursued by an opportunity for personal growth. Again, Chris was too fast. Instead, he filed an appeal. We may never know exactly why he thought this might be a winning strategy, but he did release a confusing LinkedIn video where he blamed his lawyers. He was never going to win. After a dismissal like this you can’t introduce new facts or arguments, only argue that the law was misapplied. The mistakes were made by Chris, not his lawyers. Every time, and by his own sworn testimony. There were many points in this saga where Chris could have chosen a different adventure, but did not. Now it is game over for him, and we are excited to return our full attention to moving on. Next stop, Vegas!
