DCG 719 Presents: 3D Printing

DEF CON doesn’t just happen once a year in Las Vegas. It’s happening all around you, all the time. There are hundreds of DEF CON Groups all over the world that have regular meetings, put on talks and collaborate on projects of all kinds. You can be part of the one in your area, and if there isn’t one you can start one - it’s free and the information is available at

This week we’re sharing a talk on 3D printing given at DC719, the DEF CON Group for the Colorado Springs area. Dana G. Neilson presents on the history and uses of 3D printing and shows how they made a pretty cool DEF CON ring as a handy example. More importantly he shows that what ever sector you work in or what ever you want to make, if you can visualize it, draw it and either CAD (Computer Aided Drafting) it or have someone else CAD it, then your ideas can become physical object. There are endless possibilities with this growing technology, become part of its growth and then share what you know.

If you’re in the Colorado Springs area and want to learn more about DC719, they’re online at Introduce yourself.

If you’re part of a DC Group that has something they want shared by DEF CON, drop us a line at sleestak [at] def con dot org.

New Speaker's Corner!

Sharing is our jam. We make an effort to get our product to everyone who can learn from it via all kinds of channels: YouTube, BitTorrent, direct download and even eMule. But security is also our jam. (We have multiple jams - deal with it.) So we’re putting a lot of thought into ways to make all that sharing more secure.

This post from the Dark Tangent is the first of several addressing the topic of more secure sharing, and it deals with BitTorrent.

The DEF CON 23 Call for Papers,
and Social Engineering CFP are NOW OPEN!

It’s getting real, people. The DEF CON 23 Call for Papers is now officially open! If you’ve got some good stuff to share, it’s time to start getting your pitch together. You’ve got until May 10th to submit, but don’t get too comfortable. May will be upon us faster than you probably think.

To learn the requirements for a DEF CON talk, take a look at the CFP form and get an idea of the suggested topics, we’ve put together a handy guide at Get yourself up to speed, get your forms filled out and get your proposal in front of our selection committee. This is going to be our biggest DEF CON yet, and there’s a lot of opportunities for speakers, both experienced and brand new. We’re hoping one of them is you.

As if that wasn’t enough CFP excitement, we’re also happy to announce that the Social Engineering Village CFP opens today! The requirements and submission form are online at The SE Village is very popular and it’s going to be even bigger and more ambitious this year.

SE Village also has a bad-ass Capture the Flag contest happening. Check out the Rules and Registration page ( If you want to play, read the whole thing. For real. They’re very clear on this point.

Resource Updates and a Call for Feedback.

We've added some links to the DEF CON website resource section: Some movies to watch, social media accounts to follow, hacker culture sites and technical books to get you on your way - today we're asking for music recommendations.

What do you listen to when you're sitting in the dark, making faces at your monitor? We want to compile a playlist of tunes to code/learn/fall into an internet rabbit hole by.

Strong enough to keep you typing into the darkness, subtle enough to stay out of your way when the big thinking happens — Send your suggestions to sleestak at defcon dot org!

New year image

Happy New Year from DEF CON!

DEF CON had a pretty great year, thanks to all of you. It takes a huge effort from so many people to create the kind of magical hacker summer camp that DEF CON has become, and we want to thank all of you for the parts you play:

   • The geniuses who create the talks and the geniuses who review and select them.

   • The mad zealots who dream up and carry out the contests and events.

   • The dedicated army of goons who descend upon a nondescript Vegas hotel every summer and turn it into a hacker utopia by sheer brute force and guile.

   • The attendees whose love, devotion and enthusiasm keeps this whole enterprise aloft.

DC22 had our biggest attendance ever. So big that some of the villages are probably bigger than the first several DEF CONs. So big, in fact, that DEF CON 23 will be in two hotels. Imagine that!

We will be occupying both Bally’s and Paris for DEF CON 23. More space, bigger villages, shorter lines. Like always, we’re counting on DC’s volunteers and the community at large to fill all that new space with ideas and ingenuity. It’s the greatest thing about running this type of conference - no matter what new ideas we throw out there, the community never fails to push it further than we imagined.

Thanks to everyone who made 2014 so great, and let’s get amped for an epic 2015.

Social Media Cleanup

As part of our social media housekeeping for the new year, we're leaving LinkedIn. As much as we like the service, we couldn't help but feel that we weren't using it to its potential, and that we were doing more to harvest spam than to communicate with all of you.

If you're one of the people who connected with DEF CON on LinkedIn, you should know that we won't do anything hasty. We'll leave everything where it is through January 2015, to give everyone time to collect whatever they need from our LinkedIn presence.

More importantly, we hope that you'll check out our other social media options. We have an active presence on G+, Facebook and Twitter and we're going to spend more time hanging out in r/defcon in the days ahead as well.

We have big plans for DEF CON 23, and we want your input.

DEF CON 23 Theme image

DEF CON 23 Theme Announcement!

We’re announcing the theme for DEF CON 23 early. Like, hella early. Right now early.

The theme will be ‘The 23 Enigma - a Hacker Noir’.  Fedoras and rain-slicked streets. Smoky back rooms and numbers that show up too often for coincidence.  While the good people of Everytown dream away the dark hours, the data wars rage without ceasing. Sleepless vigilantes fight for the users, though the users may never know. No matter. A bottle of the good stuff, a fast connection and the room to do a righteous night’s work, that’s enough. It’s gotta be. It’s all that’s left.

Hackers, start your imaginations.

The Dark Tangent’s announcement is here:
