DEF CON 23 CFP Graphic

DEF CON is the largest sponsor-free hacking event, and does not seek or accept money to secure a speaking spot. You have to earn your speaking spot by impressing the CFP review team with your knowledge and skill, and only then will you get your spot on stage in front of thousands of attendees interested in your research - sink or swim - it's up to you! Are you up for the challenge?

NEW for DEF CON 23

Every year some things change.

One less speaking track, more speaking opportunities.

Because of the space layout we are removing a general speaking track, leaving us with four, and adding more speaking in the villages. We'll be announcing as the various villages release their call for papers, and we'll be recording the sessions for release along with the "big track" talks.

The 101 Track

This is an evolution of the very popular 101 track last year. This year it will be in a larger track and run over all days of the conference. Are you into math but know little about cryptography? A 101 crypto talk would assume the audience is educated and interested, but don't have the real world experience. A programmer that needs to know how to hack on hardware? A 101 talk would get you oriented and up to speed with the latest trends and tools. You get the idea. Don't think zero knowledge, think instead of attendees wanting to get up to speed and doing stuff on the latest in your area of expertise.

Suggested topics

We organize talks by a combination of clustering similar subjects and stand alone topics.


A successful attack and persistence involves many moving pieces, from bug hunting, RE, payload development, targeting and deployment to less sexy but also important care and feeding of your beachhead once you have successfully compromised a target like watching the admins to see if you are noticed. Bring the offense. Attendees should get an idea where your talk lives on the attack spectrum.

Internet Defense

Attack Talks are sexy. Really sexy. But defense is where it all ends up, and in this track we will deal with the theme of defending not specific system type but instead different parts that compose the internet. What is happening now to threaten the Net, and what can you do right away to help protect it from becoming a pretty walled garden? Topics might be as specific as how to operate anonymous networks at scale, deploying private cloud services, to helping with legal briefs, contributing to a project. It might include your research in determining the scope of fraud, crime and malware networks.

Pervasive Communications

How do hackers communicate in hostile environments? It could be protocols like old school AX.25 networking, wireless mesh, your own private POGSAG pager network (Like what Telephreak ran a couple years ago), Infra Red, Satellite, Amateur radio, and more. Technologies such as censorship resistant networks like Tor, i2P, or projects such as Tribler. I'm personally interested in how secure, anonymous communities can be build and develop in oppressive situations.

Everything Else

If your talk doesn't fit in one of these topics don't worry. Those suggested topics are only 3 out of the 12+ tracks that happen during the con. The other 9 will be filled with the clustering of topics from hardware hacking and lock picking to mobile hacking, reverse engineering, and bio-hacking.

To submit a speech:

Complete the DEF CON 23 Call for Papers Form:

Like always we strive to only accept those talks of ninja caliber, and we won't have time to go back and forth asking for clarifications or missing information in your submission. Submit your best, most complete form and if anything changes email us an update.

Barring a disaster of monstrous proportions, speaker selection will be completed no later than June 15, 2015. The sooner you submit the better chance you have of us give your presentation the full consideration it warrants. If you wait until the last minute to submit, you have less of a chance of being selected unless your name is Major Kusonagi.

After a completed CFP form is received, speakers will be contacted if there are any questions about their presentations. If your talk is accepted you can continue to modify and evolve it up until the last minute, but don't deviate from your accepted presentation. We will mail you reminders with information on deadlines for when we need your presentation, to be burnt on the CD, as well as information for the printed program. If you want to plan ahead these dates are also listed on the CFP Form.

What do you get?

No matter if you are accepted or rejected the DEF CON review board will provide candid feedback on your submission. DEF CON has a collection of different subject matter experts to help select presentations based on many factors. You'll end up with a good idea how they responded to your submission.

If you are accepted

Speakers get in to the show free, get paid USD $300 or 3 Human Badges (AFTER you give a good presentation!), get a cool speaker badge, and people like you more. Most people find it is a great way to meet others interested in their topics. You can opt to forgo their payment and instead receive 3 human badges that you can give to your friends, sell to strangers, or hold onto as timeless mementos.

Receiving badges instead of checks has been a popular option for those insisting on maintaining their anonymity.

Before DEF CON we will promote your presentation, link to your social media, blog, web pages as you desire, and help arrange for any interviews from interested media that want to learn what you are up to.

During DEF CON there is a speaker party where you can meet the staff, CFP review team, and all the other speakers before the main conference kicks off and you get swept away into the vortex of Con.

After DEF CON your presentation will then be not only recorded but transcribed into English subtitles and the resulting presentations shared all over the planet through our web server, Bittorent servers, ed2k, KAD, YouTube, index sites, etc.

Please visit: for previous conference archives, information, and speeches. Updated announcements will be posted to news groups, security mailing lists and this web site. for a look at all the events and contests being planned for DEF CON 22. Join in on the action.
