Samples of the Faces of DEF CON artwork by Eddie the Yeti

Faces of DEF CON

Our community never fails to amaze. With no prompting from anyone, Eddie the Yeti has been making these beautiful portraits of DEF CON's better known faces and sharing them with the subjects.

He makes them with materials like soy sauce and coffee, wine and lime juice. He makes them insanely fast, but he still manages to get across the best of the subject's personality.

Check out his Faces of DEF CON series on DeviantArt. Check out the rest of his work, too. He's as good an advertisement as there could be for why you should come hang out with us in the desert. Brilliant, generous and doing it for the love.

Thanks, Eddie.

Pilgrim, another DEF CON regular, has made a tribute site to the series as well, at

DC22 Artwork Contest: Only Two Weeks Left!

We know that art takes time. We know that artists like to paint themselves into deadline corners, waiting until the last minute for inspiration to strike. If that's you, please bear in mind that the minutes run out in about two weeks. If you want to have your work considered for the contest, it has to be in to us by April 10. No exceptions.

Also, if you know a creative soul who might enjoy the opportunity, be sure to share this with them. We'd really love to showcase a lot of cool work this year.

Relevant data is all here:

Be the Match returning to DEF CON 22!

For the 4th year, 'Be the Match' is returning to DEF CON. It's your opportunity to register as a Bone Marrow Donor, and maybe someday save a life. There are lots of ways to hack your body, but this one doesn't slow you down at airports or make you look sketchy.

It also makes you kind of a hero.

To find out more about how 'Be the Match' works, you can check them out at these links:

Montage of past Artwork Contest entries

DEF CON 22 Artwork Contest!

DEF CON Art Contest is back!

The theme of this year's art contest is "Behind the Curtain". Secrets. Lies. Alibis. The magic shades in 'They Live'. The world behind the world, where all the hidden gears are turning.  The code and subterfuge employed by the adept to sneak knowledge past the sleeping and the uninitiated.

Cool, right? If you can put together a jaw-dropping variation on that theme in the next 30 days, prizes and glory could be yours. Free admissions to DEF CON 22, credit to burn on DEF CON Swag, maybe even a T-shirt with your art on it.

There are Categories and Rules, of course. And a Deadline. All of these are important.  These things make it a contest. But you, my undercover artist friend, you make it epic. Pencils up and good luck.


Call for Musicians/Artists/DJs application is LIVE!

If you're a musical performer, a DJ or an ambient Esperanto slam poet* who dreams of performing at DEF CON, this is your moment. We're beginning to select music acts for DEF CON 22, and we might very well need YOU.

Extra slots for Chillout/Ambient/Downtempo types this year, so you lower-BPM types should make sure to apply.

Your road to rocking DEF CON starts with reading the rules.

Then, if you think you have what it takes to entertain the DEF CON massive, fill out this form.

*I'm pretty sure I made that up, but I would be happy to be proved wrong. I will make you a Facebook star.

DEF CON Future Dates!

Sure, you know that DEF CON 22 rolls around August 7-10, 2014. Everyone knows that. But do you know the dates for DEF CON 23? DEF CON 24?

Probably not, because we're announcing it right now. DEF CON 23 will be August 6-9, 2015, and DEF CON 24 will be August 4-7, 2016.

Now you know. And knowing is half the battle.

Bank error in your favor!

When we announced the discount room rates for the Rio last month, there was some kind of glitch in the Matrix. The first 200 signups were granted a rate even lower than our block rate. The Keymaker at the Rio has agreed to honor this rate for those lucky registrants. He had the Architect explain it to me, but he droned on so long I lost the plot. What I can confirm is that the 200th registration was reached, the anomaly was smoothed over and real-world rates have returned.


As ever, Fortune favors the bold.


The corrected rate (based on occupancy of up to three per room and taxed at 12%) is:
Sunday -Thursday   $119.00
Friday & Saturday $129.00

They charge an extra $30 a night if you add a fourth. Sometimes it's worth it. We don't judge.

Even that rate won't last long – the DEF CON block is about 40% sold. To book now and get the block rate, follow this link. See how deep the rabbit hole goes.

Happy New Year from DEF CON!

We would like to wish all hackers, geeks, techs, nerds, makers, phreaks, engineers, privacy and security folks the world over a Happy New Year!

2014 will be a year of security battles, with more companies responding to news of their products being used in mass monitoring. Now is the time to get involved!

The IETF is working on the possibility of HTTP 2.0 requiring TLS always, dramatically encrypting more of the Web. Why wait?

  • - Enable HSTS on your own sites, enable EDH as well for "perfect forward secrecy"
  • - Run a tor server as middle if you don't want to be an exit. This is what we do.
  • - Encrypt your email. Don't want to fight with PGP? Then install an S/MIME certificate. IPhones work with them really well too.
  • - Encrypt your sms messages. Check out Wickr on Android and iPhone, or try "text secure" on Android, it should be on iPhone soon.

You guys get the idea. Make a resolution to up your defense game in 2014 to make life more difficult for all who would eavesdrop on us - for whatever reason.

Oh, and Hack the Planet™
