New Happenings at DEFCON 16

Well folks, the time for the 16th installment of the hacking convention known as DEFCON draws near, and this year promises to be a great one! We've got more content than ever, including 5 full tracks of talks, demos, workshops, new contests, a new Hardware Hacking Village, and even a new EFF fundraiser to replace the dunk tank! Here is some of the goodness you can expect:

DAVIX Visualization Workshop
At this "Bring Your Own Laptop" workshop we will introduce you to DAVIX. The workshop starts with an introduction to the set of available tools, the integrated manual, as well as customizing the CD to your needs. In a second part, you can use DAVIX to analyze a set of provided packet captures. In the end we will show some of the visualizations created by the participants. Be prepared for pretty and meaningful pictures! Get more info at:

Mobile Hacker Spaces
Interested in visiting a Colorado Hacker Space here at DefCon 16? Check out the first ever Mobile Hacker Space, which will be parked in the outside chill out area during the convention. Try your hand against one of the challenges in the pentest lab, or learn from the web-based tutorials posted on the open network. Participation is encouraged, and presentations will be given every day from 2-4pm, which will provide a more hands-on look at how the Mobile Hacker Space operates and fits within published hacker space design patterns. Make sure you also attend the presentation on the history and design of the Colorado Springs Mobile Hacking Space on Sunday, at 1pm in Track One. Forums link:

Quantum Spookshow
Quantum mechanics make possible some things that are impossible in the "classical" world of ordinary experience, and which even seem to contradict common sense. Some of these spooky effects are coming into practical use in security applications. The Quantum Spookshow of the National Institute of Standards and Technology (NIST) and the National University of Singapore (NUS) demonstrates quantum cryptography and quantum entanglement on a four-node quantum network, which supports quantum encrypted streaming video and violations of local realism. Participants are encouraged to interact with the light beams that constitute the physical link of this network, and to meet physicists who have designed and built quantum networks. Quantum mechanics provides methods of encryption that are secure from eavesdropping attacks against the quantum channel, but in any actual system there are points of vulnerability, e.g. correlations of classical noise in the operation of quantum elements. Participants will have a chance to discover vulnerabilities by hands-on interaction with our systems.

Hours: 10:00-18:00 on Friday and Saturday with Sunday, closing around 16:00
Location: 114. Directly across from the Contest area.

EFF Fundraiser
This year we decided to replace our beloved Dunk Tank with something NEW!
Hackers and Guns in Las Vegas – Ya gotta love it.

You've seen it played out numerous times in movies and on TV. A flash bang grenade goes off. SWAT kicks in the door and moves quickly to differentiate between the good guys and the bad guys in the same room. How do they train to effectively recognize and take out the bad guys, while not wasting any of the hostages? One of the tools they use is a Firearms training Simulator or FATS system and someone was foolish enough to let us get our hands on one for DEFCON 16.

So… Calling all Shooters, FPS Gamers, Psycho Killers, and 1337 wannabes. Come on by and pop a cap in someone’s VR ass. We will be set up in room 115 across from the contest area and next door to the Quantum Spookshow from 10:00 – 20:00. See if you got the skillz to make it through the challenges unscathed. Then the next time you hear a knock at your door in the middle of the night - you'll be ready. More at:

Warballooning Demo

A WarBalloon, er... Airborne Surveillance & 802.11 Stumbling Platform, also known as the "Kismet Eye in the Sky" will be flying just outside the DEFCON convention center on FRI and SAT from 11AM - 2 PM.

DEFCON Attendees:
please note the Balloon & Electronics launch will occur Daily at 11:00 AM & several times during the day as we change antenna's & recon new targets. (read more)

Coffee Wars: Call For Beans

In addition to whatever other insanity flourishes at Defcon each year, the last eight years have been witness to the amazing and ridiculous contest known as CoffeeWars. This single ludicrous event is really two contests. The first, and most important, is the attempt to select the finest coffee from all of hacker culture. The second is the loopy part: to find the upper limit on how much coffee the staff can drink. (read more)

DEFCON Shoot is Back!

The DEFCON Shoot is a public event happening just prior to the DEFCON hacker conference in Las Vegas, Nevada. Anyone who wants to can show up and for a small fee make use of a private range located about 30 minutes outside of the city. There will be opportunities to see and possibly shoot some of the weapons belonging to your friends and it will also be possible to rent firearms (including Class-III full autos) from the range itself. As of right now, the event's ability to come off is contingent on participation... that means that we need you if we're going to make it happen. (read more)

Defcon Goon: Speaker Operations: Call for Volunteers

From Agent X on the DEFCON Forums:
The few, the proud (arrogant?) ,the insane? Yes, that's right Speaker Operations a subset of the Defcon Goon Squad is looking for a few good folks. Speaker Operations goons are the blue shirts that ferry speakers to and from stage, keep the speaking schedule in order, and generally try to make the talks not suck... Sometimes we succeed, sometimes we fail, generally there is beer at the end. In an effort to ensure a healthy supply of goons for future Defcons, I'm holding semi-formal auditions/interviews this year at Defcon 16. Find out more here.
