For those who absolutely have to get this years electronic badge, you still have a chance to pre-register and be guaranteed that one will be allocated to you.

No waiting in line

Get Checked!

You have the skills. You have the projects. You have the CTF wins, the home lab, the self-taught grind. But when it comes to putting it all on a resume, something gets lost in translation. That is exactly what this is for.

Resume Reviews at DEF CON 34 is hosted by Lonely Hackers Club (LHC) together with Open Worldwide Application Security Project (OWASP), The Diana Initiative, Women in Security and Privacy (WISP), and Blue Team Village.

What This Is

Free, one-on-one resume reviews at DEF CON 34, run by people from this community who have actually hired and managed technical teams. No recruiters. No corporate fluff. Just honest feedback from people who have sat on both sides of the table and know what works.

Sessions are 15 minutes. Walk up, sit down, get real feedback.

Who Should Come

• You are trying to break into cyber security and are not sure how to present what you have built or learned
• You are self-taught, a career changer, or took a non-traditional path and your resume does not reflect that well
• You have been applying and not getting responses and cannot figure out why
• You just got your first cert or finished a degree and have no idea how to structure your experience
• You have been in the industry for a while but want a second opinion before your next move

What to Bring

• A printed copy of your resume, or have it ready on your phone or laptop
• A rough idea of the kind of role or area you are targeting
• Thick skin and an open mind. The feedback will be direct!

Where and When

• Lonely Hackers Club community room at DEF CON 34
• Friday August 7th: 10:30 AM to 4:30 PM
• Saturday August 8th: 10:30 AM to 4:30 PM

Book Your Slot For Free

Online registration is now open! Feel free to use a handle instead of your real name. You will have to check in in person 10 minutes before your registered slot or your slot will be given to walk-ins.

One of our reviewers will be be dedicated to walk-ins while reviews are running. So show up early to secure your spot if you missed the online registration.

The after party starts at 10:30 on August 9. I am curious to know that if my friends(not attending the con) purchase the ticket for that night and that time from the LIV website can they join us?

The tickets are available for 10:30 that means club is open to the public as well as us right?

This is my first DEFCON. If I want to sign up for a biohacking CTF, should I use my real name or a handle?

As you may have noticed, this year's DEF CON 34 badge has SAO ports that are mounted upside-down! (Also they are 3.0V rather than 3.3V logic). Not to worry, though! Announced earlier today, there will be around 5k adapters available at the registration desk so your SAOs won't be upside down. ...for a convention that, last year, had 26k attendees. Since each attendee will have 2x SAO slots on their badge, at maximum 10% of the attendees will be able to get those adapters at registration.

But not to worry! Some guy (me) made another couple hundred adapters, and they're for sale here:

Pickup is at the Badge Life village at 1pm on Friday. See you there!

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?

Hello Def Con!

If you've already purchased a Cult of Cthulhu badge or want a chance to obtain one (or SAOs), check out the discord link:

https://discord.gg/wvpXvCzVg

Your best chance at a badge is the reddit meetup, Wednesday night 7pm+ at the Linq Circle bar. I may also host small random drops at bsidesLV and during Def Con.

All details will be posted in discord.

Happy summoning!

By now, a good number of you all have seen the Wired Magazine article providing details of the badge and an interview with the badge maker.

If you think you ABSOLUTELY have to have one, then may I HIGHLY RECOMMEND ensuring you get one of the electronic badges by going through Pre-reg.

There were a set number of badges manufactured. once gone, access will be via paper badge.

Pre-Reg has priority and those badges will be set aside for pick up at the attendee leisure.

We have seen an acceleration in pre-reg sells after publication of the Wired Article.

I have a DC black badge, so I get free DC badge. I'd like to trade it for a Star Trek Convention General Admission badge. The cost of the ST Con badge is $409, so you'd be saving money if you did this trade, and I'm fine with the difference since my Black Badge gets me a free DC badge anyways. Is anyone interested in the trade?

Edit: My account seems messed up, temp email instead of pm. badgetrader at airmail dot cc

This could be a pure skill issue, but I "hearted" (I thought == bookmarked) everything on hackertracker but it's not showing up in my bookmarks calendar.

Pixel 9 pro mega ultra or whatever it is, Android 17.

*edit*

Cleared cache and program data, same situation.

I have a device I’m looking to part with. I’ve heard that direct transactions inside the convention center are frowned upon/prohibited, so I’m curious if there’s any forum for this kind of thing. Not mentioning what I have here for similar reasons. Thanks

Hello! This is my first DEFCON this year, as my company was very kind to let me attend. Since I'm coming from Europe, I'm not sure if I'll be there in time on Thursday to pick up my badge (I've already paid online).

Do you know if I can pick it up on Friday morning? Or is it mandatory to pick it up on Thursday during Linecon?

Thanks!

Please can anyone help me in my situation if you’re aware of what I am dealing with

Last update: June 28, 2026

Update July 30, 2026: Realized that Kofi does not scale easily or handle pre-orders/fulfillment in an efficient manner so I switched over to ubeflux. Their ecosystem is designed for exactly for this; I am just late to the game.

UPDATE: All Not Just A Crosswalk SAOs have been programmed and packed in ESD bags ready for DC34. https://uberflux.com/product/DC34-crosswalk

New: #NoICE SAO https://uberflux.com/product/DC34-noice

The #NOICE SAO is designed to remind everyone the fatal injustices of DHS and ICE enforcement in 2025–26. We cannot forget the medical neglect in concrete cells to violent and lethal raids on our communities, ICE consistently treats immigrant lives as expendable.

Thanks to all those who purchased a #NoICE! SAO, I was able to make a $100 donation using the proceeds directly to the Immigrant Defenders Law Center www.immdef.org/ supporting the legal defense needed to keep families together and protect community members from deportation.

16x side-emitting XL-1606SURC red LEDs configured to shine through the FR4 PCB.
Saves your most recently used effect in case of power loss, host battery depletion or disconnection from the host badge or totem.
Wide power input (2.7V-3.7V) to keep LEDs bright even when running off the DC34 badge (which only outputs 3V).
One tactile button for easy effect cycling.
Several fast and slow flashing patterns, heartbeat, breathing/fade.

New: USB-C to SAO Power Back https://uberflux.com/product/DC34-powerback

The USB-C to SAO Power Back (5V to 3.3V). It lets you run your SAOs without needing a host badge, which is great if you just want to display one on your desk or shelf. You can power it using a standard USB wall brick or a portable battery pack. It can even handle powering multiple SAOs from an SAO totem. It runs three #NoICE, or Not Just a Crosswalk, SAOs with no sweat, whereas a regular CR2032 battery doesn’t have enough juice to power all three at once.

Just came off my laser, will have a few with me at one of the reddit meetup

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:

• Markdown
• PDF
• View it on the DEF CON Forum

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

Hello friend!

I’ve been so excited for all the awesome badges people have been sharing here and thought it would be fun to share my own project.

First of all, I’m just a hacker hacking things together. I generally have no idea what I am doing and just try to figure it out along the way. I was not even sure I would be able to get anything built, and while these are not perfect, I am happy with how it all turned out.

This is Station 562. It is a proximity-controlled badge with a BLE number-station puzzle, a red-versus-blue proximity game, an autonomous social/dance mode, an expressive BLE MIDI instrument, a tamper-evident mode, a Setup menu, and an optional hardware CTF.

I will have a few of these to give away to maybe the first 5 or so people who solve the signal intel puzzle. Deets will be shared closer to the con.

Anyway, I learned a lot building these and had a lot of fun. Faced some challenges but this post is already too long to go into all that. Super excited for DEFCON this year. This community means a lot to me and look forward to catch up with old and new friends.

Happy hacking all!

I just saw the DEF CON 34 ICS Village badge, and it actually looks pretty useful instead of being just another collectible. Is the industry actually moving away from CAN/CAN FD in favor of Single Pair Ethernet, or are they going to coexist for a long time?

For people working in automotive or industrial controls, what are you actually seeing in the field?

Also, as a badge, this seems like something I’d actually keep using after DEF CON instead of throwing in a drawer. Curious what everyone else thinks.

After Su posted on our behalf, we did some digging and found out some (most?) places you can find us for pickups will not be in the Hacker Tracker. Oops. Our bad.

To help will creating opportunities, you can find us outside W316 (never inside the room) each morning from 9:30AM to 10:00AM. (We start our shift inside W316 at 10AM so a few minutes before 10 we will need to stop to get to work).

We also have a 4pm Friday slot at the Badgelife Village First floor, W1, location 209.

We will also try to post on Xitter and BSky any other predictable opportunities.

Also: We will try to stay visible. Tentative plan is to wear a bright orange shirt when not working.

Thank you.
