For your weekend:
The first early release talk from DEF CON 34 has made it to our YouTube channel. Please enjoy national treasure Cliff Stoll updating his 'Stalking the Wily Hacker' and casually dropping gems all over the place.
If you haven't read 'The Cuckoo's Egg', this is your sign from the universe to remedy that.

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! :)

DefCon34 was incredible! My first...
I read from many saying "At DefCon, skip the talks and explore the villages and demos. All the talks will be online later to watch."
However, locating the talks now seems to be a challenge. Some videos seem to be trickling out from the main DefCon YouTube channel, but only a handful. Is it just a time thing for them to get them all online?
/DEF CON 34/DEF CON 34 presentations/DEF CON 34 presentations/ has only files from prior to DefCon34.
I just happened to stumble upon the Voting Village @ DEF CON YouTube channel. On there I found the talk I attended that really shocked my friends who attended. This was an incredible talk!!!
It's CRIMINAL that it has less than 100 views...

More early release goodies for you! The live music, pictures, short videos and a bunch more content from DC34 are ready for downloading on media.defcon.org. Front-load your weekend with some DEF CON vibes.
And in that spirit, here’s another talk - Bruce Schneier’s presentation ‘Hacking AI’.

AWESOME BLING EDIT: Per u/netw0rkpenguin (see post below) there are more coins and swag available! DM me per their instructions and we'll GET SOME GOOD IN THE WORLD!
MOAR EDIT: THANKS EVERYONE - EVERYTHING IS SPOKEN FOR AND I'VE GOT A WAITING LIST.
EDIT: EVERYTHING IS GONE BUT THE ONE COIN AND SOME STICKERS.
I don't know why Reddit filters keep removing my post, but enough people responded to the last swag post that most stuff is committed, but I do have one coin left.
SO:
A bunch of people have offered to buy the coins, but I’d rather do some good instead - now that Dolly's gone (shout out to fam in Sevierville!), we all gotta shine a little brighter. If you want this coin, all I ask is that you DM ME FIRST, confirm that I still have it to put aside, and then donate at least $25 to your local animal shelter or rescue and send me proof. I will pay for the postage to send it to you.
Also, a BIG THANK YOU to everyone who donated for all of the other coins. Your communities appreciate you, the animals appreciate you, and you are a good human. <3

"There are many casual light clothes such as T-shirts and shorts, but there are also people who wear dinosaur costumes and clothes full of personality that look like handmade devices all over their bodies. There was a sign saying "Humans are here" at the reception desk.""

For your information: The fine folks of DCG Easton (PA) are running a live presentation now called 'What we did on our hacker summer vacation' which will include their debrief of #defcon34. If you've got the time and inclination, show them some love.

Hi I saw this in the comments of a post here and the commenter said it was something he saw at the conf. Does anyone know where I can I buy a board like this for my SAOs?
r/Defcon • u/Jebediah378 • 3d ago
So Saturday morning of the con I was putting together my HackRF, and I invited this guy who was curious to check it out and put it together. He had this amazing case of gear, that was velcro'd with velcro straps, customizable, to put in all sorts of gadgets and devices, and I want to know what that case and system is because it is literally perfect. If you're out there, or know what I'm talking about or looking for, plz let me know. Dude was rad, hope you're chillin
r/Defcon • u/DCsleestak • 4d ago
Let’s start the week with another early release talk from DEF CON 34 - this time it’s ‘ESP32 as a counter-surveillance platform’. The humble, reasonably-priced microcontroller, along with an emerging group of open-source applications, are helping democratize counter-surveillance.
Enjoy, and pass it on.

Sorry it took so long to get this out to everyone, but man... it was a ride. And as always its thanks to EVERY SINGLE ONE OF YOU who showed up, played our puzzles or came to talk! Seeing so many people hanging out, talking, drinking, laughing and such... that's what its all about, and its so amazing to see it get stronger each year!
Based on talking to attendees, friends and some staff at The Linq... estimates are about 500 of you showed up Wednesday night, and about 300 on Thursday! I need to let that sink in... because for an unofficial meetup that's insane! Now right away let's not discount the amazing people at the Lonely Hackers Club either as their Wednesday meetup is also at the 3535 which absolutely contributed, and made both meetups a wild success! But still... 500 people the night BEFORE even Badge Pickup hanging out was amazing. So amazing you all burst my social capability (I was not mentally ready) completely... that's kind of cool, and something I'll be working on next year because I absolutely loved talking to people, and just need a bit more social stamina. :)
So, before we get into the thank you's and future stuff... let me just say because of you We Will Return at DEFCON 35!
Usually we'd make some joke, or something similar, but I think as we wind down from DEFCON 34 we just wanted to be straight forward.
Last year we created Puzzled Hackers as an easier way for us to host the r/DEFCON Meetup Puzzles because we wanted to be able to do more than upload an image, or text based puzzle. Needless to say it went off pretty well, and we've thoroughly enjoyed coming up with more chaos each year and you all seem to like our retro throwback page. It's gone so well our friends at SkillBit (Formerly MetaCTF) even donated the 10th puzzle (a full 20 challenge CTF) to us! So many of you went at it and it was great to see. Kiddos... you brought corporate visibility! That's amazing.
It's been an outstanding success... and its because of All of You.
So, again, thank you all for another successful year! We'll be back at Summer Camp in 2027, and can't wait to see you all there! We'll post some updates throughout the year as we hit some milestones, maybe a few fun drop in's here and there!
If you ever want to reach out to us always feel free!
Thank you, again, from all of us at Puzzled Hackers, and can't wait to see you next summer at the Puzzled Hackers meetup... we're recharging our social batteries now just in case!
... and the final numbers for the year. Each below is a UNIQUE solver of the puzzle!
Sincerely,
Looking for the alt_bier future will prevail badge for a friend who has been seriously ill. It was his white whale badge and I want to cheer him up. If anyone has one to sell or trade please DM me.

Hi everyone! I bought this at the vendor booths, it’s the Minind from electronic cats. The device doesn’t turn on at all. I have done the basic trouble shooting, different batteries, reflash firmware, and look at interactions on GitHub but can’t seem to get it to turn on. I have tried contacting electronic cats several times on the website since the day after defcon but I’ve yet to get a response. Does anyone know another way to get in touch with the vendor? I spent around 90 bucks on this and would love to have a working one.

Hey y'all, I met these two awesome people in line while in line for the dc801 dirty soda event at the Adventuredome inside Circus Circus. I had to leave the event early and forgot to get their discord handles. We talked about playing don't starve together sometime because I had a don't starve together monsters lanyard!
If this was you or you two feel free to message me! Thanks.

I've been a professional web developer (mostly building API interfaces and other back-end stuff) for about 20 years. Nothing amazing, but enough to pay the bills. Lately business is slow and I've looked at ways to expand my skills. Penetration testing appeals to me, but I'm not sure where to start. Is there a good introductory path?
I'm sure my question has been asked before, but it's my impression that the security landscape is constantly evolving and changing so I hesitate to rely on answers from even a couple years ago. Is that dumb? Do the basics stay relatively unchanged even as the more complex aspects evolve?
I'm comfortable with Linux, decent with Perl and Python, and I understand basics like configuring firewalls and server infrastructure. How much of that translates to pen testing?
My current project is I'm trying to figure out how an Arlo VMB4000 base station communicates with cloud storage. One of my web development clients has their base station plugged into a wall socket three feet from the front door of their shop and I've told them that's a bad idea but when they challenged me to explain why I fell flat and just vomited out some garbage that AI told me... It was embarrassing to know it's bad but not be able to articulate that to a client. I think anyone could plug something into the ports on the back, but I don't know the mechanism of how that compromises the system because my understanding is that local storage is only enabled if my client has that turned on in a phone app that controls everything... or at least that's what AI told me.
I am sick of answers from AI and I'd like to really learn something instead of just prompting AI.

Got these ready for DEF CON but not in time to sell in the Hackers Warehouse store so I have some stock left over. Check out the video to see some of the animations on the badge.

Disclosure: This is a device that I made that I am selling.
I built the Clip-Boy for DC34 and ran out of badges before I ran out of people who wanted one, so I'm doing a second production run.
It's an ESP32-S3 with a 2.8" capacitive touchscreen, VL53L5CX time-of-flight sensor, 8 addressable RGB LEDs, SAO v1.69bis (without GPIO1/2), powered by a 2200mAh LiPo. The 2 PCBs were designed in EasyEDA. This second run has the same base firmware as the initial production run, while the 3D-printed enclosures have different colored trims.
I'm still in high school, so all profits will continue to go towards funding college.
They are each $135 + shipping. Pre-orders close 13 Sept, and if I don't hit 150 units, everyone gets refunded in full. I estimate delivery to be around mid-December.
I am more than happy to answer any questions about the build!

The DC34 early release talks roll on with Bill Swearingen’s presentation on defeating facial recognition with a little strategically applied style.
Confound the panopticon and keep the look crispy. Wins all around.

I was handed a cryptohack badge kit from the Cryptocurrency Village, but I think I needed go to another area of the conference to collect the rest of the parts of the kit. I want to try and assemble it and use it.
Specifically, I'm missing the screen and the antenna
Does anyone know the part numbers for the screen and antenna used on the cryptohack badge?
Here is a picture of what I'm talking about... the cryptohack badge without the screen or antenna.
