Anyone here grab a photo with me? I think, at one point, I had a line of 20+ people to take a selfie. Please tell me wearing this all the way from the Flamingo was worth it in the 110+ degree heat 😩

Hey now,
Looking for info on a board from defcon34. Does anyone know where this board was at or where I can purchase it now?

I understand some of the free workshops had info sites or online guides available, with the instructor(s) leading participants through them. I wasn't able to get into the workshops and would love a chance to read through the info and learn at home, especially for "WS8 Wi-Fight Club: I am Jack's Evil Twin" and "WS2 From Prompt to PWN: Exploiting LLM Powered Web Applications with OWASP Techinques".

A few people have been asking about the game that was running on the screen in Packet Hacking Village near closing and after hours.

It’s called Hardcount, and it’s a project by Doc, a DC community artist and longtime contributor who has been part of the community for years. He took a year off to teach himself game development and put that time into making this.

I wanted to give it a little more attention because this is the kind of project I think is worth supporting. Not just because it’s a game, but because it’s something a longtime member of the community decided to take a chance on and build from the ground up.

Hardcount is currently on Kickstarter, and Doc is trying to reach the funding goal. If you know Doc, have crossed paths with him in the community, saw the game at PHV, or just want to support someone putting their time and energy into making something new, consider backing it.

And if you can’t back it, sharing the Kickstarter helps too.

Anyone know where the official photos are from the Villages? Was in Packet Hacking Village when the official photographer was.

Attention DEF CON attendees: the excellent folks of DEF CON A&E would appreciate your input on how they can keep improving the music side of DEF CON. If you could take a moment to fill out their quick survey, we’d be most grateful.

Does anyone know the default password for the robot badge that rok was selling in the DC34 vendor village? I cannot figure out how to connect to this thing.

TIA!

Edit: For anyone who doesn't know it's "123456". Have fun meshing!

Some thoughts about DC 34.

I'm not really an OG, and I'm not a n00b. I'm friends with a lot of OG's though, I guess.

I hear a lot of negative talk about DC not "being like it used to be". This year it seemed like there were quite a few "I'm a n00b and this sucks" reddit threads early in con.

That wasn't my con. Not this year.

The magic was back. Our magic was back.

I'm not going to name names, they can comment if they want, but it is a shared sentiment. We've talked about it.

We spent time running communities, villages, contests. We also spent time in talks, meeting new people, learning things at villages. We also put away our duties. We hung out each night, with a revolving group of people. We sat in hallways. We talked. We laughed. We did silly things, funny things, epic things. We made new friends, and hugged old ones. We ate, and drank, and smoked. We were mischievous and curious and good hearted. We partied, we whispered, and we laughed and we cried. We remembered those passed. We planned for next year. We glowed in the sense of community, and shared spirit.

We focused on people and connecting, and our magic came back.

I hope yours did too.

Hi there! I make music and art under the alias CadoFox, and I work for Zebbler Studios as an artist and on-site as part of A&E for the con. I'm the artist behind this Defcon Banner, as well as 3/4 of the video loops on that giant video wall at the front entrance! (flat render that only con and ZS were sent above as proof, can provide more if anyone REALLY wants lol)

I am new to this community, this was my first time doing both content and on-site work (both were SO much fun), and I had initially gotten permission from the con to get to take this banner home after the con was over, but it seems someone got to it before I did... (I was told this was quite normal lol)

Its honestly really cool that someone liked it enough to take it, but It would honestly mean the world if this could at all make its way back to me somehow! This was a very meaningful milestone for me. I unfortunately can't offer much in return, but I will buy it back for a reasonable price if needed I suppose. I can also cover shipping ofc.

If anyone knows anything of where it ended up, dm me here or my ig (same user). Hope everyone is doing alright post-con!

First off, shoutout to everyone digging into the badge at the con and who shared and posted their findings. You all inspired me, and this year's badge is one of my all-time favorites.

For the meatbags who don't know, the DC34 badges are all a simulated genetic population under the hood: each badge has a genome, and is equipped with various genetic reproduction mechanisms: diploid (2-strand) genome, meiosis with linkage groups, Gray-code mutation, and an inbreeding penalty (when two badges of the same type exchange). The math is clean enough that it decomposes into a few array ops, so I ported the genetics core out of the Rust firmware into a single dependency-free HTML file and ran 10,000 badges in the browser as a live 100x100 grid of animated 5x5 LED tiles. It's a Monte Carlo of the questions the physical conference can't answer at any real statistical power: how fast does the shooting-star (lin<88) phenotype drift, fix, or vanish? Does the inbreeding penalty actually diverge isolated subpopulations, or does mutation just swamp it? Does the asymmetric nonlin expression (slot-0 chaser leaks into slot-1 nonlin, bug or feature, you decide) shift the population median in a measurable way?

Companion writeup on the GitHub repo with the full derivation from dc34-api/src/lib.rs, and the whole sim is one HTML file. View source, tweak the rate, reseed, watch it evolve.

(Did I mention it's got borg mode?)

EDIT: Also added the ability to generate nonce and seed QR codes, so you can now use your physical badge to mate with any genome you create in vim gene. Step-by-step instructions are here.

Just saw a pic of the yo yo on Twitter. Anyone grab one that they want to sell or barter for?

Thank you guys for another wonderful time with everyone. I can't wait to see old friends and make new ones on the flip side <3

was doing some last minute soldering on the phreakme 2600mhz sao in the BadgeLife Village and the usb-c solder irons were all dead so plugged my Anker battery into one but was rushed out during closing and forgot to snag after packing my bag, If anyone know anyone running that area and found it while packing up please dm me.

I'm the project manager for the Hacker Tracker family of apps (used by DEF CON and other conferences), and I also oversee the comprehensive convention schedule that gets published in Hacker Tracker for DEF CON. We (my team) would love to get your feedback about the app and the DEF CON related data in it; we'll consider this feedback when prioritizing the improvements/features we work on in the near future.

Did you discover something new, that you weren't aware was there? Did you look for something that wasn't there, but you wish it was? Or did something just outright not work correctly? Give us your best and worst.

When commenting, please be as specific as possible -- at least mention which platform you're using (Android, Apple, web), as they are different implementations.

Thanks! :D

Was wondering if anyone had any issues with TSA regarding any of their defcon electronics and/or respective batteries in their carryon?

I took all the batteries out and plan to put them all into one ziplock bag. If they say no to that, I will just trash them.

If they say no to the electronics, I hope I can buy a checked bag and put them in there or something?

Just want to make sure I can take everything back etc.

Hi, I’m CJ, head of the SOC Goons.

While the con is still fresh in everyone’s minds, I’d like to ask you to take a moment to share some feedback. How did your con go? How were your interactions with my team? Most importantly, how can we do better?

We have a challenging set of objectives. We have to interact with everyone, and not always about friendly things. We’re often your first interaction with the con, and it’s difficult to be an ambassador and an enforcer at the same time.

I hope it’s obvious to those of you who’ve been attending for a while that we’re a very different team from even just a few years ago. I’m still looking for ways to improve, and making the team more transparent and accountable was one of those steps. This post is another step in that direction.

We love DEF CON and we serve this community. That’s why we’re getting quicker at removing Goons who don’t share that vision, and doing it earlier in the process. New Goons are now trained, evaluated, and then re-evaluated before they’re allowed to call themselves Goons.

I’m looking for feedback, whether it’s positive or negative, but preferably constructive.

Thank you for an awesome DEF CON 34. Its was both hard work and a lot of fun. I wish I could have been out on the floor amongst all of you more, but i’m still recovering from breaking my neck. Regaining stamina has been a long journey along with re-learning walking lol

Last, I’ve never had more people come up and tell my team how much they’re appreciated. Honestly, that made their year.

I went to steak con at the Golden Steer and noticed a server wearing Meta glasses. I could see the camera; no light to indicate recording, but I got the impression it's easy to put a sticker over the light, unless newer models don't allow them. Got home and finally had time to call them out about this privacy invasion and possible credit card theft and their response was disappointing to say the least.

If you went there, check your credit card receipts. They said the server disables recording, but why am I gonna trust some random in a place that has a $12,500 wine on the menu? Do they think I'm paying that in cash?

Really disappointed with this place. The food was great.

This was my second year at DefCon. Another great experience. While I'm more of a maker than a hacker, I've realized just how much the DefCon crowd is "my people". I'm usually a very quiet and shy person and don't go out of my way to talk to people (#Autism). While I was at DefCon this year, I realized that I was acting way different than usual. I was talking to people in a way that I usually only talk to myself in my head. I felt comfortable talking to people in ways that I almost never do. I wasn't in my head the whole time and words just flowed from my brain to my mouth in a way that is very uncommon for me. The only thing I can attribute it to is the high number of like-minded individuals and the anonymity that comes with such a large conference. For the last two years I've been working at my company's booth which helped nudge me into talking to people more, too.

Anyway, basically, DefCon is awesome and I'm already looking forward to next year. If I weren't able to attend with my company at some point, I think I'd reach out and try to volunteer as a goon.

See you at DefCon35!!!

I had a limited supply of coloring sheets so you could make your own fake badge at DEFCON 34. Since the con is over, I thought I'd share with you all.

https://github.com/riskymanag3ment/defcon34/blob/main/DC34%20Coloring%20sheet.pdf

Also if you found one of these and colored it in, I'd like to see pictures.

I wanted to go but I lost track of time. I bought the recordings but they will take a while to get to me. What was the talk like?

With all the conference action our visitor action hit 21k

We gained about 400 additional DEFCON.social users signing up.

Great week everyone!

Now that we are back home and settled I wanted to thank everyone at Defcon, from the Goons, to the Villages, to the Attendees for gifting so much to my service dog Scooby and making this another amazing Defcon for us. He loves attending the convention just as much as we do and making new friends along the way. Defcon always makes us feel so safe and included, and this having been our fourth one, we are excitedly looking forward to next year!

PS: sorry Blue Team Village, but Red Team Village won this year with a patch and a badge. Lol.

( I wish I could thank everyone individually, but then this post would be way too long. Lol.)

So… it obviously not only good for QR codes.

I’m completely aware that this is super rage-baiting at this point but I don’t really enjoy being lied to.

Sure. It’s not a phenomenal camera. But it’s enough to take pictures of faces and with a proper lens would have a better focus.

The attached photo is 800x600. The camera goes up to 1600x1200. It’s high enough resolution to take pictures of faces and text.

I haven’t attempted it yet but I assume any arducam would work with the ribbon cable connector on the board of the badge which would allow for me, tolerances given, to place a much higher resolution camera.

This badge breaks DEFCON camera policy:
“Smart glasses and other devices that can record audio or video with no consistent way to understand if they're recording or not, are prohibited at DEF CON, they erode trust and invade people's privacy.”

EDIT 1: Photo was taken an arms length away.
EDIT 2: Added a bit more information about reusing that connector for a higher resolution camera.
EDIT 3: Added smart glasses and OTHER DEVICES policy
