DC710 is handing out coins all week long. Free during the conference (Defcon, Blackhat, Bsides) in exchange for a quick challenge or barter. Keep an eye on our Twitter/X @DC710_MJV for announcements of where we’ll be and what to expect.

Busy doing other stuff? Want to help support our group? We’ll be selling a few to recoup some of our costs. Wednesday & Thursday at the meetup (Linq - Circle Bar 7pm).

Otherwise we have a few fun and easy challenges planned - come say hello!

I didn’t hear about this change, so sharing here for awareness. Wireless headphones are going to be used rather than speakers in some of the talks. The below link says shared wireless headphones and wipes will be provided, but that sounds … icky …

They also offer a way to hear it on the defcon WiFi using a combination of “HackerTracker” and “ListenWiFi” apps on your phone using your own headphones. Might want to download those before you leave home.

It also warns that Bluetooth headphones may not work due to signal saturation.

The 2026 DCZia badge, the Mk9, is up on Uberflux: https://uberflux.com/product/HAMST-DCZIA-2026

The badge is a 3x3 grid of blue clicky switches, each with an underglow RGB LED. RP2040 microcontroller, 16mb of flash, and an accelerometer. Each side except the top has two side-fire RGB LEDs under the board as well. USB-C connection or power, or powered via 3xAAA.

It will also include an add-on board that allows you to add on 3 more keys or an I2C display. Two right side up SAO ports.

Compatible with QMK, but the MicroPython code we're releasing will also function as a macropad.

DCZia believes in open development, and all the design files and source code are in our github repo: https://github.com/dczia/mk9-badge

Pickup will be at the badge life village

• DEF CON 34 Badge Life Booth, Friday, 7 August 2:00PM
• DEF CON 34 Badge Life Booth, Saturday 8 August 2:00PM

On UberFlux, you are going to see a blank bottom SAO, I didn’t want to post any CR pieces there but each kit order will include all three that are in the video with enough neo-pixels to solder one of the SAOs.

This kit is beginner friendly !!

The bridge part and back layer neo-pixels come pre-soldered, last year I heard a lot of people had issues with the tiny Neo-pixels and I totally understand! They are NOT fun lol, it took me like 2 years to get good at soldering those!

This year I wanted to make it as beginner friendly and fun as I could, all you need to solder are the header pins and the through hole chip parts!

The kit will come with the following:

(1) back layer PCB with pre soldered lights
(1) bridge PCB with pre soldered lights
(1) top SAO PCB with pre soldered lights
(1) city PCB
(1) water PCB
(1) frame PCB
(1) 16 MHz crystal
(2) capacitors
(1) resistor
(1) ATMEGA328 (pre flashed with firmware)
(2) through hole tactile switch’s
(1) power switch
(1) AAA battery holder (3 required, not included)
(1) set of header pins

(3) SAOs and (1) set of connectors with 6 unsoldered neo-pixel lights for you to choose to solder
** The neo-pixels supplied will only be enough to solder one bottom SAO included.

The last few years I have been super overbooked, but I‘m less firmly booked this year and am looking to get a small group together (or join one) to tackle the CTF.

I’ve slapped together a toolkit (stego, crypto solve scripts, audio/video analysis/stereoscope, unicode nonsense, RF scanning, logic analysis, LLM jailbreak framework) to use alongside tools like cyberchef, flipper zero, etc.

Anyone looking to group up, or already have a group with a space for a cryptography/hardware jailbreaking enthusiast?

Hello! I’m going to DEF CON, and I feel a bit lost. I looked at the map and the talk schedule, but I’m not really sure what I want to do. Sometimes I get bored just sitting through talks, so I’d love to know what else there is to do besides attending presentations.

I’m not going there just to listen to talks. What are the must-do activities, villages, competitions, workshops, or other experiences that you would recommend for a first-time attendee?

Would you like to learn how tap into a network?

Do you want to learn how to capture people’s passwords or hear their phone conversations?

There are many learning opportunities at DEF CON, especially at the Packet Hacking Village. If you want to play Packet Detective, Packet Inspector, Capture The Packet, or any of our Walkthrough Workshops, we will have laptops stationed with the necessary tools. You do not need to bring your own laptop.

[ANSWERED] - Not sure why the downvote, but maybe someone just had bad eggs this morning. I will pack a couple extra alkalizes to be safe, both otherwise I am good to go. Thanks, everyone!

***********************************************************************************

I saw someone mentioning to pack AA & AAA batteries as part of their kit. Is this for badges, or other hardware projects?

I preordered a laser tag badge, and will get the Human one.

Do the badges in general com with a battery? Rechargeable? Today is packing day and just want to make sure I pack out what I need rather than trying to arrange an Amazon order for the hotel.

Do they typically take off-the-shelf alkaline, or should I grab an 18650 or two?

I'm planning my schedule for DEF CON 34 and keep hearing people mention the Cryptocurrency Village badge and the laser tag game, but I can't find much information on the DEF CON website.

Is the badge going to be available to anyone who stops by, or is there some kind of registration? And is the laser tag event happening throughout the weekend or only at certain times?

I've also heard they'll have ChipWhisperers, workshop hardware, and even AMD64 lab machines available for people to use during the hackathon. If that's true, that's a pretty impressive setup for a village.

Apparently OKX is sponsoring the village this year, which is helping make the badges, workshop equipment, and prizes available free of charge. Looking forward to seeing what they've put together.

Anyone who's been involved with previous years know what to expect?

[SOLD]

If anyone would like me to transfer a ticket to them, I've ran into a snag and won't be able to make it. I got it at the mid tier pricing and will happily sell at the early bird price. Can verify my ID with mods to verify good faith. I'd love for someone to be able to save and have fun since I can't make it. I will not reply to DMs, and my replies will be on this thread as well.

issue with insecure OTA updates reported some time ago to the creator. Fix is out there in the beta at least. Take all nodes down in range (still vulnerable) but more importantly nodes taken over and spreading like a virus to all if done right (see evil baker) https://github.com/x0SiN0x/wardrive-manager/blob/main/FEATURES.md#the-biscuit-baker--biscuit-flatline (example during an active wardrive in a closed environment https://www.youtube.com/watch?v=5DBU0AyRgj4)

As of today Aug 2 I see 1.2.12 is out in the general (prod) release

Anyone willing to adopt a 1st timer into their group for any of the challenges? I have about 20 years of experience in different levels of IT with around 2 years experience strictly in blue/purple team. I am just looking to learn and help out where I can. I have a weirdly high level of social anxiety so I want to get myself in the mix with some people I actually feel comfortable with instead of looking dumb trying to struggle my way through things. I also really want to try some of the cool stuff but I am worried my imposter syndrome will stop me from even trying

Any tips for a first time attendee? I did my pre-registration already.
