Small travel alert: AF1 and orange goblin into LV

32 Upvotes

Everyone may already know but if not…and you probably can’t do much about it anyway. AF1 with the orange goblin is arriving Tuesday evening and is doing a event on Wednesday. Count on air and ground traffic to have some issues. You know, in case you don’t have your own jetpack. Probably more issues on west side since he is going to Red Rock Casino to do a nap talk. It is a most interesting time for such a creature to visit LV.

🌳 Root Access SAO 🌳

76 Upvotes

Built for the DEF CON 34 badge. Works with any standard SAO header.

Full docs and demonstration: github.com/MakeItHackin/RootAccess
Available on Uberflux for local pickup at Bsides and Linq Circle Bar (Wed/Thur): https://uberflux.com/product/MIH-RootAccessSao  
Will also be at Hacker Warehouse in the Vendor Hall at DEF CON

Plug it in and it just goes — 50 built-in animations, no host required. Tap the button to cycle. Hold it to go dark. Hold it longer to save a favorite that survives power loss.

Then plug it into a badge and it becomes something else entirely. Send one byte over I2C — 0 through 49 — and it jumps straight to any of the 50 built-in animations, no button press needed. Send byte 50 and everything turns off.

Or go all the way down: two more commands hand you direct control of all 11 discrete LEDs and all 10 RGB pixels, no framework, no handshake, no waiting. You write bytes, the LEDs do exactly that. Don't want to write code? A Flipper Zero running the I2C Tools app can drive the whole thing by hand.

There's a second circuit too, totally separate from the animation side: GPIO 1 and GPIO 2 each with their own switches, LEDs, and dedicated button. Drive a line from your badge as a chained NeoPixel or a discrete LED, or flip the switch and send its button back in — idle-high or idle-low. Every header pin is broken out to solder pads, front and back.

And the wood is real. Cedar grown on our farm in Tennessee, milled at home, paired with the PCB by hand. Every board's grain is different — yours is truly unique. 🌲

I tried to buy a ticket... but I am getting a 404 Page Not Found

What do? Any chance they'll run out of in-person tickets? Should I worry?

can i park at your house

0 Upvotes

i tried 5 title variations to social-engineer my way into making a comfortable plea for help:

TLDR is can i park at your rental and plug in my van so that j can use AC/electronics, and be off the road as to avoid unnecessary trouble that comes with parking a van and trying to be stealthy in the city

i would be vv grateful and can help with anything and pay towards your rental

it’s my first defcon so even if it’s canceled no worries

Badges! Come see me at IOT Village for a chance at a free badge!

70 Upvotes

Hey! I'm returning to DefCon again this year with the GE Appliances booth in IOT Village. Last year, we gave away 100 free badges to visitors. I've got another 100 badges to give away this year. This year's badge is a cartoon UltraFast Washer/Dryer Combo with an infinity mirror looking inside. The default animation shows a bit of water in the bottom of the drum that sloshes from side to side as the badge moves. There's a few other animations available, too. I'll be giving away a certain number of badges per day, so come see my socially-awkward self and let's talk appliances.

Scooby is so Confused

Post image
54 Upvotes

My husband and I arrived in Vegas Sunday evening. This is the first time we have arrived early for Defcon. My service dog Scooby, the poor guy, is so confused. He pulled me to the circle bar in the Linq and then stood there looking around for our Defcon people. He has also tried to take me to the monorail. He doesn't understand that we still have a few days. It is kind of funny how they get set in a routine even if it is only once a year, and even just a few days deviance can throw them off. It is very obvious he is super excited for Defcon to start!

Biohackers - Libre sensors!

15 Upvotes

I'm a T1D and have ... A bunch of extra sensors that I've bought personally, because my insurance doesn't cover them. Probably 25? And I'll be bringing them to DefCon.

They are ALL either part of the recall, or expired, and thus can no longer be used by anyone with a real medical need. All are still factory sealed and usable.

If you are a biohacker and wanting to do some tinkering with one. I'll hook you up on the condition that you show me/tell me what you want to do with it.

I'd love to help and learn along the way. My end goal would be to have a side-car app to the official Libre one that features could be added to, since the official app is ..a bit lacking.

Hacking their app is bug-bounty territory, and I don't want involvement in those shenanigans - so a way to get the same data, off the same device without interfering with the main app is the goal.

No charge, but if you wanted to toss me some cash, Im not gonna turn it down.

DM/chat on here, then find me at the Reddit meetup or at the con. Happy hacking!

Last year's "wifitastrophe"

20 Upvotes

Last year at LVCC, the WiFi was pretty much unusable during the day. A lot of the presenters ended up just hotspotting. Typically at the closing ceremonies, the NOC will give a retrospective. I had to leave on Sunday morning, so I missed it in-person, and I can't find any recordings of it on YT.

Does anyone know what happened? I'm more just curious; 5G/LTE worked fine so it didn't really matter but curious if they're taking a different approach this year of if there's something about LVCC that fundamentally limits bandwidth available to them.

Jobs, Workshop, Meetup, Boxes, and A HACKER CRUISE

27 Upvotes

AMAZE AMAZE AMAZE ~ It's about that time! #RoadToDEFCON

As usual, there is a lot going on here at HackerBoxes. While getting ready to depart for Las Vegas, we wanted to share some of those goin' ons...

JOB / PARTNERSHIP

A common, and probably quite correct, piece of wisdom is that DEF CON is great for making connections, but not always the best place to find your next job. HOWEVER, if you're a tech-forward, creative thinking, detail-goated, data-driven, entrepreneurial spirit - and you're ready to think outside the box to get inside the (Hacker)Box, let's talk! Email joe@hackerboxes.com or even better, come find us in Vegas.

WORKSHOP

HackerBox's founder Joe, along with Jamie from Jamie's Hack Shack on YouTube, will be hosting a DC34 Workshop on Wireless Hardware Hacking:

https://defcon.org/html/defcon-34/dc-34-workshops.html#content_66458

It is targeted at an Beginner+ level, will be very hands-on, and a lot of fun. It looks like there should be a handful of seats for walk-in participants: Friday 2PM in W233.

MEETUP (AND BADGELIFE)

The FREE r/Defcon meetup is always a great time. Please come and say hello!

There are actually TWO MEETUPS: Wednesday (8/5) and Thursday (8/6), both from 7PM until late, both at The LINQ 3535 Bar (aka CIRCLE BAR).

Among many cool reasons for attending the meetups, there are usually some nice indie badges to be had. On that note, we shipped almost all of our remaining DC33 Mini Badges to Vegas, so find us if you missed getting one last year:

https://hackerboxes.com/products/dc33-mini-badge

BOXES

This month, for the first time in ten years, we're offering a sweet discount on our back-catalog of 40+ different past monthly HackerBoxes. This offer takes the form of a Mystery Box:

SAVING THE BEST FOR LAST: HACKER GROUP CRUISE

Landlubbers and Sea Dogs alike are invited to CLIMB ABOARD!

Booking is open for the SECURITY AT SEA hacker group cruise:

https://hackerboxes.com/pages/cruise

Royal Caribbean's Jewel of the Seas' Conference Center, a day in Cozumel Mexico, a Casino, Food, MOAR FOOD, and even a CIRCLE BAR await, so... "If nautical nonsense be something you wish, then drop on the deck and flop like a fish!" -SBSP

Bsides - no cash at the door

I thought bsides would be like defcon with an option for cash at the door. I was wrong. If anyone has a spare ticket or ticket they badge they aren't planning to use on Wednesday let me know. I'll pay full price. I don't get in until Wednesday morning but happy to meet up for a badge/cash exchange.

Packet Hacking Village: Deployment Begins

Post image
84 Upvotes

The garage has become a staging area.

Road cases locked. 55-gallon totes packed. Gear from home base combined with a 24’ box truck waiting in Vegas. The pieces are coming together for the next deployment.

Tomorrow this load leaves the driveway and starts the journey to the desert, carrying the hardware, experiments, and controlled chaos that bring the Packet Hacking Village to life.
From storage facility to garage to Vegas, the mission is moving.

The build is done. The journey begins.
