DEF CON 26 Voting Village Report Released!

Posted 9.27.18

The Voting Village Report from DEF CON 26 is live now! We hope you’ll take some time to read it in full. In the Voting Village’s second year, the selection of devices was expanded to more than 30 machines, all but one of which are still in use across the USA right now. We also made a very successful effort to attract election officials to observe, participate and even get training from cybersecurity experts.

The many vulnerabilities discovered are listed in some detail. For example:

"A voting machine that is currently used in 26 states is vulnerable to be remotely hacked via anetwork attack. Because the device in question is a high-speed unit designed to process a high volume of ballots for an entire counties, hacking just one of these machines could enable an attacker to flip the Electoral College and determine the outcome of a presidential election.

A second critical vulnerability in the same machine was disclosed to the vendor a decade ago, yet that machine, which was used into 2016, still contains the flaw.

Another machine used in 18 states was able to be hacked in only two minutes, while it takes the average voter six minutes to vote.”

While these results are cause for concern, the DEF CON Voting Village also provided Election Day Crisis Communications Protocols with the aim of suggesting clear best practices to mitigate the exploitation of the election infrastructure.

Please share this report widely. The only curative measure for misleading headlines is accurate information, and the security of our democratic process requires that we understand the problem clearly. If you are concerned about the vote tech in your area, get in touch with your local representatives. If they’re not aware of our project, share it with them.

We want to thank the organizers of the Voting Village, the election officials from around the nation who came to learn from our research and the hackers at DEF CON who brought their talent and ingenuity to the task of securing our voting process.

Yet another DEF CON 26 Early Release: Booby Trapping Boxes!

Posted 9.22.18

More video from DEF CON 26! 'Booby Trapping Boxes' by Ladar Levison and hon1nbo is a practical talk about high impact, low cost hardening for a chronically insecure world. From the abstract:

"Whether your running servers as a high value target, or simply want to protect your Monero private key, this talk will show you to achieve FIPS 140-2 level 4 security, without the FIPS 140-2 level 4 price tag. Specifically, we'll cover acquisition considerations, physical hardening, firmware mitigation, tamper detection and more."

Enjoy, and pass it on.

DEF CON 26 Early Release: Inside the Fake Science Factory!

Posted 9.18.18

More DEF CON 26 video for your perusal: @5uggy, Till Krause and @sveckert deliver a timely and important breakdown of the fake science industrial complex. From the abstract:

"This talk presents the findings and methodology from a team of investigative journalists, hackers and data scientists who delved into the parallel universe of fraudulent pseudo-academic conferences and journals; Fake science factories, twilight companies whose sole purpose is to give studies an air of scientific credibility while cashing in on millions of dollars in the process. Until recently, these fake science factories have remained relatively under the radar, with few outside of academia aware of their presence; but the highly profitable industry is growing significantly and with it, so are the implications. To the public, fake science is indistinguishable from legitimate science, which is facing similar accusations itself. Our findings highlight the prevalence of the pseudo-academic conferences, journals and publications and the damage they can and are doing to society."

Enjoy, and pass it along.

More Early Release Video from DEF CON 26: What the FAX!

Posted 9.14.18

More video from DEF CON 26! This time it's the ancient, humble fax machine's turn in the security barrel.

From the abstract:

"What the Fax?! ...We went to work, determined to show that the common fax machine could be compromised via mere access to its fully exposed and unprotected telephone line -- thus completely bypassing all perimeter security protections and shattering to pieces all modern-day security concepts."

As always, please enjoy, be edified and share far and wide.

DEF CON in the News: Voting Village Report Incoming Edition

Posted 9.12.18

The team that runs the DEF CON Voting Village has announced that they will release findings from DEF CON 26 next week. The report from last year's Voting Village was widely cited and helped jump-start the conversation about improving election tech security.

There has been controversy, with vote tech manufacturers and some state officials challenging the results and the methodology of the hackathon. TechTarget has an interview with VV's Jake Braun about this year's results and some behind the scenes info about the expanded efforts at this year's Voting Village.

DEF CON in the News: Voting Village Edition

Posted 8.22.18

4 senators sent a bipartisan appeal to @essvote urging the vote-tech firm to engage with the independent security research community. They asked Election Systems and Software to make voting machines available for testing and to share the results to increase transparency.

“Election agencies must be able to make informed decisions about what election equipment will help them conduct secure elections, and independent testing helps both election agencies and vendors.”

This is why we have a Voting Village.

We approve this message.

First Early Release Video from DEF CON 26!

Posted 8.18.18

For your first post-DC26 (and pre-DC27!) weekend, here's the first video release - Rob Joyce, Senior Advisor for Cybersecurity Strategy at the NSA giving his presentation 'NSA Talks Cybersecurity'.

From the abstract:
"The National Security Agency (NSA) has authorities for both foreign intelligence and cyber security. This unique position gives NSA insights into the ways networks are exploited and the methods that are effective in defending against threats. Over time, NSA has adapted the focus of its security efforts and continues to evolve with technologies and the adversaries we face. The talk will look back at some of the inflection points that have influenced NSA and US Government cybersecurity efforts and look at what is necessary to stay safe in the new environment."

As always, enjoy and share widely.

Caesars Palace Update

Posted 8.16.18

A team from DEF CON management met with Caesars on Tuesday. They are looking into the reports we presented, and we’ll share what we can as those investigations play out.

Here’s an overview of the current policy as shared with us:

1. DND tag on the door too long triggers a security visit.
2. That security visit is supposed to be by hotel security staff who are clearly identifiable as hotel security staff.
3. That visit should be comprised of a visual survey of the main segments of the hotel room, with no fiddling about in personal belongings.

This means that entering rooms and taking a quick look around does not violate the hotel’s policies.

But it also means that reports of opening closed bags, confiscation of personal effects, and reluctance to self-identify and/or allow guests to verify the legitimacy of the security officers all fall well outside of the policy.

Please know we are not letting this go. We are sympathetic to the new terrain major hotels find themselves in, but our main commitment is to our community. We intend to stay on this until we’re satisfied these issues are resolved for next year.

Updates as we get them.

DEF CON 26 is a Wrap!

Posted 8.14.18

Just like that, DEF CON 26 is in the books. We want to thank all of you for making such a success of our little hacker party every year - there is truly no community anywhere like the DEF CON community.

The Dark Tangent announced in closing ceremonies that next year we'll be back at Paris/Bally's. Also a bit of Planet Hollywood. Even more space, but less exposure to deadly solar radiation. We're already planning ways to use it all.

This was a big year for us. We doubled the villages. We grew the workshops. We pumped up demo labs and contests, and we even learned how to set up the crazy lightshow required by the mighty Juno Reactor - which you will get to see shortly, since they let us record their set. (Yay Juno Reactor!) Also, we did that thing in Beijing that went so nice we're doing it twice.

We're gonna take everything we learned from this year's crazy expansions, fine-tune things and bring all that new wisdom to DEF CON 27. If you have ideas, feedback@defcon.org stands ready to accept them.

Thank you for all that you share with us, all of your enthusiasm and love that animates everything that happens here. Congratulations to everyone who won something, or learned something, or tried something weird and new. Cheers to all our old friends and our brand new ones. We love you, and we can't wait to get together with you next year.

DEF CON 26 ATTENDEE REPORTED INCIDENT POLICY

Posted 8.6.18

As a followup to my last post we realized that if we were hoping people would emulate our policies at other conferences we may as well release our attendee incident reporting policy as well. The version given to all the DEF CON Goons is the same as below but also includes confidential reporting phone numbers.

ATTENDEE REPORTED INCIDENT POLICY

DEF CON does not tolerate harassment of any kind, be it racial, sexual, physical, political, intellectual, or emotional. Every Goon shall take each report by an attendee seriously, and not dismiss any of them. Never turn an attendee away. It is not a Goon’s duty to judge anything that an attendee says, regardless of opinions of the attendee, the person they’re reporting, or the reported issue itself.

Reported/Observed Harassment or Assault
When an attendee reports harassment or assault to any Goon follow this procedure:

1. Get a second Goon to be with you to listen to the report.
2. Have one goon contact a SOC goon via the SOC Contact Procedures
3. Make a warm hand off with the attendee to the SOC Department.
4. Let the SOC conduct their investigation and handle the incident from there.
5. Be available to answer any questions from the SOC or venue security.

Interaction with Social and Traditional Media
DO NOT SHARE photos or videos. Please let the responding SOC GOONS know if you have any video or pictures, they may end up being evidence, but out of context could cause problems.

During or after an incident, you may be asked to comment on the situation. DO NOT make any comments to reporters, and do not post about the incident on social media. As a Goon, the media will treat anything you say as an official statement from DEF CON. Commenting prematurely before we understand the situation could cause more confusion or reveal identities that should remain confidential so please refrain from speculating and work with SOC / PRESS to help them understand what happened.

Refer all media inquiries to the DEF CON Press Department (press@defcon.org or send them to the press room)

DEF CON 26 Support Resources!

Posted 8.5.18

In my last post about the DEF CON Code of Conduct, I mentioned that I wanted to make sure that the community had all the tools necessary to get involved and report problems when they arise.

In this post, my last before the con, I'll talk about some of the new efforts we are deploying for DEF CON 26. It will be our first year for some of these, so we are looking for feedback. You will notice a theme of transparency, appropriate given the theme of this year's con!

NEW WAYS TO REPORT ISSUES: The DEF CON Support Hotline

You can reach DEF CON staff during normal hours of operation (8am to 4am) to anonymously report any behavior violating our code of conduct or to find an empathic ear by calling +1 (725) 867-7255. Trained community volunteers will be standing by to help any attendees.

You can still report issues by going to any Info Booth or talking to any SOC Goon, but sometimes you may not want to be walking around in person with a problem, and so this year we have added a phone option.

NEW SUPPORT RESOURCES:

We are collaborating with several organizations including Kick at Darkness, The Rape Crisis Center Las Vegas, and the Nevada Coalition to End Domestic and Sexual Violence to provide expert resources for survivors, including dedicated support for LGBTQ+. When you call the Hotline you will reach DEF CON community Goons trained to help in these areas.

NEW WAYS TO IDENTIFY GOONS:

In the past there has been some confusion by attendees with what Goon they were actually talking with.

New for DEF CON 26 Goons should all have visible patches with their nickname on them so it is easier to remember who you talk to about what. The name patches should be attached to the front of the Goon's lanyards and be more visible than the back of a shirt that might be covered by a backpack.

Please use the name on the patch if you have any feedback on Goons, good or bad. Feedback can be sent to feedback@defcon.org, written and dropped off at registration, or if serious enough called into the Hotline.

MORE DETAILED TRANSPARENCY REPORT:

Based on the positive community response to our closing ceremony transparency report, we plan to do this every year and hope other conferences do as well.

As people get comfortable reporting issues I expect the numbers to increase, and only by facing these issues head on can we hope to prevent them. It requires courage to speak truth to power, or to report something that is unpleasant in your community, but together we can make things better.

See everyone soon!

Get hyped, fam. We're in the home stretch.

DEF CON Code of Conduct

Posted 7.27.18

When I designed the updated DEF CON Code of Conduct in 2015, I had a few goals in mind. Make it simple to understand, express in broad strokes what kind of behavior is not acceptable, and don't be too specific.

I wanted it to act as a template for other conferences, if they chose to do so. It was legally reviewed by our outside law firm and a specialist. In 2018, it's looking like it may get seriously crash tested.

The Code of Conduct assumes people are acting in good faith and not creating intentionally elaborate, dishonest or disingenuous claims of harm. "Ah ha! This is where the bad actors will attack the CoC" you may be thinking.

As a conference of hackers, our CoC is intentionally flexible: like a spoon in the matrix. We describe generally what is not acceptable as opposed to trying to enumerate 42 different bad behaviors.

Besides the CoC, DEF CON has several structural factors that are to our advantage when dealing with people intent on disruption. This is not our first conference, and as such we have a department dedicated to dealing with this problem. We have also had time to plan with hotel and casino security should we need their involvement. We take this issue very seriously and choose to err on the side of removing people, rather than allow them to spoil the conference for those who just want to contribute in a positive way.

Finally, I have always said that DEF CON is what you make of it. I want to make sure our community has all the tools necessary to identify and report unacceptable behavior. Together, we will have all the pieces in place to act quickly and professionally, no matter what the issue is.

Contests and Events at DEF CON 26 posted!

Posted 7.14.18

Now that you’ve had a whole day to absorb the epic Village list, we’ve got some more goodies for you. The Contests and Events page is now LIVE, and it’s also quite a bit to take in. Ranging from the straightforward elegance of the Tin Foil Hat Challenge to the complexity of an Industrial Control Systems CTF competition, there’s contests here for just about any hacker discipline, and every level of skill or experience. Contests are also a great way for the shyer among us to beat the icebreaker blues and get right into some fun with a bunch of likeminded strangers.

The more extroverted attendees can still opt for a Charity Mohawk or the cringetastic glory of Hacker Karaoke.

Block off a little time for pre-con recon and make a plan to make sure you get to sample widely from the smorgasbord of C&E offerings.

Our reunion draws ever closer, fam. Get amped.

DEF CON China Talk Video!

Posted 6.12.18

Please enjoy the video of the Keynote presentation from DEF CON China! It's the redoubtable Dan Kaminsky, and his topic is "Bugs Aren't Random: Unifying Building and Breaking in the Modern Age." Many topics are covered, as viewers of previous Kaminsky talks can attest.

We also offer you the estimable and renowned Vito Genovese from the mighty Legitimate Business Syndicate, discussing the lessons taken from five years running the DEF CON CTF contest.

From the abstract:

"This presentation will cover topics about all aspects of CTF organization: the history of CTF, building a cross-functional organizing team that sticks together year after year, developing a game infrastructure that handles the onslaught of attacks from players, and the stories behind some of the most difficult CTF challenges ever built."

As always, enjoy and share the info. Be sure to join us in Vegas for the brand new CTF run by the scrappy upstarts in The Order of the Overflow.

DEF CON 25 Transparency Report!

Posted 6.4.18

At the closing ceremonies of DEF CON 25 last year we shared the results of our first public transparency report - an account of the incidents we dealt with throughout the con. The report now has a permanent home on the DEF CON website, and we’ll be updating it after every event.

We’re hoping that this kind of reporting catches on. It’s a good way to know where to concentrate our efforts, to attach more public accountability to the DEF CON Code of Conduct and to familiarize our community with how we handle con-goers’ concerns.

So check it out, and check back after DC 26 to see what went down behind the scenes..

PS whoever brought that one ‘vicious animal’ to the party - Hey. Don’t do that. Jebus.

DEF CON 26 Homework: Critical Thinking Edition!

Posted 5.9.18

More Reading Homework for DEF CON 26!

Another way to keep dystopia at bay: question everything. Widen your information funnel. Examine the framing. Check your sources.

In the spirit of DEF CON 26’s theme “1983: The View from Dystopia’s Edge”, we offer some homework reading with a focus on critical thinking.

First up, the delightful “You are Being Lied To”. It’s compiled by the redoubtable Russ Kick of the legendary first version of disinfo.com, and it’s a sage, provocative collection of bite-size think pieces from all over the cognitive map. The only through line is that many of your assumptions are garbage. Start anywhere, and let it shift your paradigm.

https://archive.org/details/media_You_Are_Being_Lied_To

“The Undercover Economist” is Tim Harford’s wry take on the basics of economic theory, with a special emphasis on the strange and counterintuitive ways the tangled forces of the economy affect your daily reality.

The final assignment for today is Walter Lippmann’s ‘Public Opinion’. Written almost a century ago, “Public Opinion” is an eerily incisive and prescient take on the way your opinions are crafted and slipped into your head while your attention is elsewhere. Less dated than you think, and packed with meaty insights for the ‘post-truth’ era. Prepare to question how (and why) you know everything you think you know.

Happy reading! Stay tuned for more assignments in the coming days.

Roundup of DEF CON Updates!

Early bird reg for DEF CON China [beta] has now closed. Online reg remains open for those who prefer it, but please be aware that the standard DEF CON method of paying at the door works just fine.

The brand-new Ethics Village (ethicsvillage.org) is accepting talk submissions until June 22.

Car Hacking Village (carhackingvillage.com) is still open.

Hardware hacking village is looking for talks, art and demos. Check their forum thread for more info.

New Soldering Skills Village at DEF CON 26!

Posted 4.27.18

Announcing new for DEF CON 26, the Soldering Skills Village! The SSV will focus purely on soldering and making at DEF CON while the HHV will focus on bringing more hardware hacking resources than ever before!

The change-up is beneficial for everyone, it means both villages can get quiet and well-lit spaces. It also means the two volunteer groups can better support the DEF CON community in their own ways. Both villages will maintain an open share of knowledge and volunteers between them. The SSV and HHV will coexist at DEF CON and provide the most that they can to all DEF CON attendees!

Also: Got something you want to show off, teach, or blab on about? Let us know about it! Shoot an email to [email]l33tbunni@dchhv.org[/email] Now accepting submissions for demos, talks, art, anything hardware you want to show off!

Space Announcement for DEF CON 26!

Posted 4.25.18

DEF CON 26 is getting close and now is the time to let everyone in on some big changes we've got in store. We've accepted a record number of villages and are growing the number of workshops from last year. To hold all this goodness we are growing to include the Flamingo hotel.

TL/DR

- DEF CON has has accepted more villages than ever before and needs to grow.
- DEF CON is spreading to two hotels, Caesars Palace and the Flamingo.
- This lets us do more stuff + evening pool parties.

The PLAN:
For DEF CON 26 we will try something we have never done - Split the con between two hotels! No, not like Paris + Ballys, they are connected. I'm talking Caesars Palace and the Flamingo across the street.

"That's Crazy!" you say. "Why do we need that much space?" you say. Check this out: The number of villages will almost double from last year to about 25. Parties should increase. More contests are under development. DEF CON needs space to support all the awesome projects from the community and I'd really like to throw some pool parties. That is all now possible.

In the next month you will hear more specifics but I want to answer some questions here:

- How will the space be split? The Flamingo will hold some of the "destination" events to relieve pressure off of Caesars Palace. Current planning includes Workshops, DEF CON 101 track, some villages and contests, a chill out space, pool parties, and more once we finish planning.

- Will there be DC TV at the Flamingo? Yes DC TV will be in the Flamingo and as many other hotels as we can wire. A more definitive list soon, but we are building on what we did last year.

- If you ran a village or contest last year you should count on the same or more space you got last year. If you are running a first time event we will work to meet all of your needs. If you want even more space or a dedicated spot at the Flamingo we can work on making that happen.

Background:
With the move to Caesars Palace last year we got more space and a different floor plan that helped with some flow, but the broken escalators stole some of those gains. For DEF CON 26 the escalators are fixed and we have a better understanding of how to use the space. With that understanding and the growth of interest in Village and Contests we realized that we are out of space and need to span to a new property. This growth will allow us to accept more contests and villages and try some new stuff while giving existing events some room to breathe.

DEF CON 26 Homework Assignments Roll On!

Posted 12.15.17

We've given you a lot of reading so far, so here's an assignment that can be completed in under two hours - The 2006 Alfonso Cuarón film 'Children of Men'.

The movie fits the theme of 1983 by being a thoughtful and moving study of hope and resistance in the face of calamity and misrule. It also features a bunch of stellar performances and some crazy precision camera work (keep your eyes peeled for the long, unbroken takes).

'Children of Men' fits our theme in other ways, too - the set design could hardly be more in line with our DC26 style guide. Concrete skies, graffiti, neglected brutalist edifices everywhere - it's probably as close to a match as you're going to find so feel free to take inspiration from it.

Watch this space for more assignments!

DEF CON in the News!

Posted 12.7.17

The DEF CON Voting Village co-hosted an event with the University of Chicago's Harris School of Public Policy to highlight cyber vulnerabilities in our elections infrastructure. At the event, Noah Praetz, Director of Elections with the Cook County, IL Clerk's office issued "2020 Vision" a plan that details ways federal, state, and local government can work together to improve the security posture of U.S. voting infrastructure.

DEF CON in the News!

Posted 12.5.17

Here's the full video of a hearing of the House Subcommittee on Information Technology regarding the Cybersecurity of Voting Machines. One of the testifiers was Matt Blaze, security superhero and DEF CON Voting Village organizer. It's a good read for anyone who wants to be thoroughly grounded on the state of election security and the plan for moving forward.

"The results of the Voting Village were summarized in detail in a report. It is notable that participants, who did not have any previous special expertise in voting machines or access to any proprietary information or source code, were very quickly able to find ways to compromise every piece of equipment in the Village by the end of the weekend. Depending on the individual model of machine, participants found ways to load malicious software, gain access to administrator passwords, compromise recorded votes and audit logs, or cause equipment to fail. In most cases, these attacks could be carried out from the ordinary interfaces that are exposed to voters and precinct poll workers. The first machine was compromised by a participant within 90 minutes of the doors opening."

You can read the full report from the Voting Village.

And a transcript of Matt's remarks

DEF CON 26: The Homework Continues!

Posted 12.1.17

The heart of the DEF CON 26 theme is the concept of the counterfuture. The counterfuture is the open-source alternative to totalitarian dystopia; a world where we use tech and ingenuity for empowerment and connection rather than isolation and control.

In the spirit of the counterfuture, we offer book two in our pre-con homework series: ‘Cryptonomicon’ by Neal Stephenson. It’s a bit of an epic, so you’ll want to pencil in some real reading time. The story concerns two historical inflection points, WWlI and the eve of the 21st century. In both eras, Crypto and savvy are all that protect us from a spreading and despotic darkness. In both, hackers (of various kinds)are the carriers of the counterfuture.

Enjoy, and stay tuned for more assignments.

DEF CON 26 Call for CTF Organizers Reminder!

Posted 11.29.17

Friendly reminder to all of you Capture the Flag rock stars - there’s still time to put your stamp on the Super Bowl of CTFs at DEF CON 26!

We’re looking for a team with big ideas and the skills to execute under pressure. A team that wants to push the limits and create challenges that people talk about for years.

If that’s you, read the requirements at https://www.defcon.org/html/links/dc-ctf-cfo.html and get in touch. We look forward to seeing what you’ve got.

DEF CON 26: The Homework Begins!

Posted 11.28.17

In keeping with the DC tradition of releasing a list of books, movies and other cultural products to help you get into the headspace of our theme, we offer the first suggested reading assignment: 'Little Brother' by digital-age soothsayer and frequent DEF CON speaker Cory Doctorow.

Don't let the YA trappings trip you up - the book contains a toothsome examination and critique of the dangers of the police state and the role that hackers, makers and like-minded troublemakers can play in turning the tide.

It's also fun. Share your thoughts with us in the comments and stay tuned to this space for your next assignment.

Happy Thanksgiving from DEF CON!

C-SPAN coverage of Voting Machine Security Forum

Posted 10.11.17

Here's the C-SPAN coverage from the aformentioned Atlantic Council event, enjoy!

DEF CON 25 Voting Machine Hacking Village Report Released!

Posted 10.10.17

Today at a Washington DC event hosted by the Atlantic Council, the long-awaited DEF CON 25 Voting Village Report was released. You can even watch the presentation live on CSPAN 2 - The Dark Tangent is headlining the event!

During the weekend of DEF CON 25, every single device in the Voting Village was compromised. The report we’re releasing today gives a glimpse into how much we were able to discover in only a few days. Any committed threat actor would devote vastly more time and resources, and we believe that democratic governments must treat the security of election systems with the same rigor and investment as they do their borders.

We entered into this experiment as a non-partisan public service, believing that discussion about solutions has to start with a realistic assessment of what needs fixing. The DEF CON community has a lot of talent in that kind of work, and we saw a way we could contribute.

We would like to thank everyone who joined us in the Voting Village to test the machines, everyone who collaborated on the report, the Atlantic Council for helping us share the results and the Library of Congress for granting an easement of the DMCA provisions that would have blocked this research. This project is a great example of government making room for independent researchers to bring their talents to an issue that matters to all of us. Here’s hoping there will be more success stories like this one.

LegitBS Blog on Running CTF for DEF CON!

Posted 10.6.17

Vito from the Legitimate Business Syndicate has started blogging about the experience of running the past five (stellar) DEF CON CTF Contests.

Recommended read for anyone interested in CTF, especially anyone considering responding to our call for CTF Organizers. LBS is top-shelf, and if you’re going to learn, they’re the kind of teachers you want.

DEF CON Capture the Flag Call for Organizers!

Posted 10.2.17

After five years of exemplary stewardship of the DEF CON CTF, the shadowy masterminds of the Legitimate Business Syndicate are ready to retire to the shore house. However, whenever life closes a door, hackers jimmy open a window. LegitBS will be missed, but for someone out there a giant opportunity has just opened up.

We know some of you have genius ideas for making your own mark on the world’s premiere CTF competition, we want your proposal. In return for your fresh blood and fanatical devotion, we offer eternal geek glory and a place in the pantheon next to LegitBS, DDTEK, Kenshoto and the all theheroes who have made this contest their own.

There’s a lot you’ll need to know to submit, and you can read all about it on our CTFCFO page.

For inspiration, check out this Mega-panel of previous CTF organizers from DEF CONs past, courtesy of DEF CON 25.

If you’re ready to graduate from the combat arena to the control room, get your ideas together and let’s make some magic. Valhalla awaits.

DEF CON 25 News Roundup: Voting Machines Edition

Posted 9.21.17

The #votingvillage we introduced at DEF CON 25 is still in the News - mainly because it’s being cited as one of the driving forces behind a growing shift in attitudes about the security of ballot machines.

In Virginia, the State Board of Elections voted to decertify it’s touchscreen voting machines in time for the November gubernatorial election, and one of the reasons given was the discoveries at DEF CON. We’re hoping for increased focus on security and accountability in our voting systems, and we are pleased to see the subject getting broader attention.

https://www.usnews.com/news/best-states/virginia/articles/2017-09-08/virginia-bans-certain-voting-machines-over-hacking-concerns

There’s also a very informative episode about DEF CON by the fine people who do all the ‘How Stuff Works’ podcasts. The first half is devoted to a thorough explanation of DC history and the second half is an interview with the wonderful Shannon Morse (@Snubs) about her experiences there as a human and in her professional capacities as a vendor and journalist. It’s from their TechStuff series and it’s worth a listen, especially if you’re new to the community.

The DEF CON 25 Soundtrack Raises Funds for the EFF!

Posted 9.5.17

In case you didn't know, the DEF CON 25 Soundtrack is available on Bandcamp as a 'pay-what-you-want' item. All proceeds go directly to keep the exemplary humans at the EFF fighting for the users. So for a modest donation you get dope music from DC25 performers and that warm feeling that only comes from selfless do-goodery.

The DEF CON A&E Team also auctioned off an artist badge for $321. Add that to the current Bandcamp sales of $423.37 and our donation match and you get a current payout to EFF of $1506.

"But the EFF does so much!" you say. "Surely I can still contribute to push that number higher?"

To which we respond, "Yes. Yes you can."

Click that link. Get some tunes. Relive the sounds of DEF CON 25 and toss a little change in the bucket to help the EFF keep cyberspace free.

Do it today, and then make sure to pass it on.

Posted 8.28.17

Now we take you way back to July 2017 for a leisurely Q&A with two impressively clued-in congresspeople; Rep. James Langevin from Rhode Island and Rep. Will Hurd from Texas.

Ever wondered if there was such thing as a “hacker-friendly” member of Congress? We found some and convinced them to come to DEF CON so you can meet them too! In this first-of-its-kind DEF CON session, two of the most hacker-friendly Congress critters will join DEF CON for an engaging and interactive session with the security research community.

Join the Atlantic Council’s Cyber Statecraft Initiative for a candid discussion with Representatives Will Hurd (R-TX) and James Langevin (D-RI). The two Congressmen share their thoughts on the latest developments in cybersecurity policymaking on the Hill, exchange ideas, and maybe even answer some of the Congressmen’s questions.

#VotingVillage is a hit!

Posted 7.28.17

For a rookie, the Voting Machine Hacking Village is off to a very impressive start: consider the following tweets:

90 min after doors open: Complete remote control on the operating system level of the Winvote voting terminal (including election data).

On the e-pollbook front: internal data structure already discovered and reverse engineered within an hour. #VotingVillage

The Voting Village has a bunch of machine makes and models to try your hand at, including Sequoia AVC Edge, ES&S iVotronic, Diebold TSX, Winvote, and Diebold Expresspoll 4000. More importantly, there's a chance to make a little history here. The integrity of voting systems is a live issue in the world's news, and there are a lot of eyes on our little experiment. If your idea of fun includes a little paradigm-shifting, the VotingVillage is open all DEF CON.

In Memoriam, the DEF CON Conference CD

Posted 7.27.17

Let's face it: this change has been looming on the horizon for a long time. When we started putting a compact disc full of slide decks and files into the DEF CON goodie bag, it was a perfectly good idea. In those days, 750 megabytes was a decent amount of storage. More importantly, optical discs were still a thing. Readers shipped with all the computers and we all had cool CD wallets and racks and whatnot.

The world has changed, and CDs are now a weird novelty item from the hazy past like Pet Rocks and Cassingles.

This year, you'll find all that juicy data on the DEF CON media server (media.defcon.org) and you can connect at your leisure and leech to your heart's content with no silly plastic doodads to hunt down of when you're loading out your hotel room.

We will miss the Conference CD. We had good times together. We will toast to your memory, and pour out a little data in your honor. See you on the flip side, old friend.

DEF CON 25 Entertainment Lineup!

Posted 7.19.17

Curious who's gonna be rocking the house in the wee hours of DEF CON 25? Here's a handy guide to the MainStage performers for all three nights! Enjoy, plot your entertainment journey and pass it on.

Just a little over a week! W00T!

*Richard Cheese and Lounge Against the Machine are performing in the Chill-Out Area, the rest of these performers are on the main stage.

Full-spectrum psychedelic bassquake - ZEE is back!

Posted 7.17.17

Saturday Night, y'all!

Zebbler Encanti Experience (aka “ZEE”) is what happens when Pixel Wizard and Techno Badger meet in the woods and decide to short circuit neural pathways of the nearby mushroom pickers with nothing short of bassquakes (9.0 on the scale of awesome) and complete visual reality replacement (somewhat too awesome and terrifying to be numbered anything in particular).

That historic meeting in the woods is the underpinning of the very garments that ZEE now wear at every event they perform. The mere loosening of a button of their coats' pockets opens up a wormhole of psychedelic visions and sub-sonic rattles. But Zebbler Encanti Experience do more than that. They open their minds fully to each and every dance floor and ask you to Get In There!

Richard Cheese and Lounge Against the Machine are BACK for DEF CON 25!

Posted 7.15.17

Friday, in the Chillout area, please to enjoy the nearly-too-swanky-to-function  sounds of returning DEF CON performers (and DEF CON Soundtrack contributors!) Richard Cheese and Lounge Against the Machine!

America's loudest lounge singer Richard Cheese performs swingin' Vegas versions of rock and rap songs, "swankifying" popular Top40 hits into retro vocal standards. Imagine Sinatra singing Radiohead, and you've got Richard Cheese & Lounge Against The Machine.

The aforementioned DEF CON soundtrack is included with admission at DEF CON 25 or by donating to the EFF (url coming soon).

DEF CON 25 Friday Headliner: Reel Big Fish!

Posted 7.14.17

For your DEF CON After Dark enjoyment, we present Friday's headliners, Reel Big Fish! They're fresh from their Beer Run Tour and ready to bring their trademark SoCal skank to the DEF CON masses.

In case you're not familiar, a bio snippet: "Reel Big Fish were one of the legions of Southern California ska-punk bands to edge into the mainstream following the mid-'90s success of No Doubt and Sublime. Like most of their peers, they were distinguished by their hyperkinetic stage shows, juvenile humor, ironic covers of new wave pop songs, and metallic shards of ska."

Sounds fun, yes? Yes.

DEF CON 25 Village Spotlight: ICS VIllage

Posted 7.13.17

A small group of SCADA Ninjas are traveling around the globe, spreading the word of SCADA. Unless you are already operating a secret nuclear enrichment facility in your basement or an ACME factory production line, then this is your best chance to get a kick-start into the world of Industrial Control Systems. We are bringing a number of real-world industrial devices from different vendors for you to look, feel and mess around with.

We bring you a safe, yet realistic environment where you can learn on how to assess, enhance, and defend your Industrial Environment. We bring you real components such as Programmable Logic Controllers (PLC), Human Machine Interfaces (HMI), Remote Telemetry Units (RTU), Actuators, etc. to simulate a realistic environment by using commonly components throughout different industrial sectors.

You will be able to connect your machine towards the different industrial components and networks and try to assess these ICS devices with common security scanners, network sniffers to sniff the industrial traffic, and more! In addition to previous years there is a workshop dedicated to ICS 101 and 201. Afterwards there will be an additional but optional challenge to test your newly acquired skills.

Follow @ICS_Village or have a look at www.ics-village.rocks.

New for DEF CON 25:
Voting Machine Hacking Village!

Posted 7.11.17

"Just like everything else, it's time for hackers to come in and tell you what's possible and what's not."

-The Dark Tangent

Judging from the headlines, it's a good time to figure out how secure our electronic voting machines are. What better way, we thought, to find out what's real and what's hype than getting a bunch of real voting machines into the hands of thousands of hackers? We happen to know where to find a lot of hackers onthe last weekend in July, so we created the Voting Machine Hacking Village. We're bringing a bunch of voting machines and encouraging people to see what's possible. Let's test the physical security, try attacks at a distance, dump the BIOS, all of it. Knowing is half the battle, people. Let's do our part to add to the base of knowledge.

Read all about it:

A DEF CON 25 Announcement

Posted 6.15.17

BAD NEWS:
No DEF CON 25 Mystery Challenge or badge contest.

WHAT HAPPENED?
Curious Codes, the company that was designing the DEF CON 25 badges, notified us they are no longer working on any challenges or badges for DEF CON.

WHY?
A combination of design and planning delays combined with a last minute unforeseen personal circumstance made their production impossible.

WHAT DOES THIS MEAN FOR DEF CON?
No special badges or challenge and no mystery challenge

SO NOW WHAT?
We've gone with a DEF CON 25 anniversary theme with the badges and have worked around the clock to get them designed and ordered. Not to fear, we are hackers, it will work out. Everyone will have badges, they just won't have crypto, secret embedded robotics, or radioactive compounds. I'll talk more about the joy of conference badges in a later post.

WAIT, THERE WAS GOING TO BE ANOTHER MYSTERY CHALLENGE?!?
Yes, L0st had planned to do a special DC 25 challenge to break everyone's minds.

ERATTA
Stay tuned for more info on #badgelife, we are planning a badge meet up for all those who enjoy building and collecting conference or contest specific badges of all kinds.

Village Spotlight - Crypto and Privacy Village Edition!

Posted 6.14.17

Privacy is important to everyone, both in terms of the abstract legal right to secure our information and the concrete availability of tools and means to keep that data secure. In this age of near-ubiquitous surveillance, it's a good idea to keep your security knowledge sharp.

To that end, the Crypto and Privacy Village is back with a full roster of presentations, contests and workshops to level up your privacy game. Follow them @cryptovillage, or get the full rundown at cryptovillage.org.

Beardless, but interested in competing? Please know that there is a freestyle category that actively encourages the creation and display of faux, ersatz and/or fictive facial hair arrangements. Fanciful and improbable designs welcome.

Village Spotlight: Packet Hacking Village

Posted 6.10.17

Once upon a time, the Wall of Sheep was mostly a bunch of paper plates stapled to a wall, shaming DEF CON attendees for bad security practices. It has grown into a whole village full of packet shenanigans with its own speaker track, contests and even workshops.

There’s loads of information on their wallofsheep.com, including the speakers they’ve so far selected for DC25. There’s a lot to take in, so it pays to get familiar in advance. The Packet Hacking Village has enough going on to satisfy all packet ninjas, from Padawan to full-blown Jedi. Visit their site, follow them on Twitter @wallofsheep and get your chops in order. The mischief starts next month.

'Better Know a Contest’: Crash and Compile Edition

Posted 6.6.17

Crash and Compile is part drinking game, part programming contest. The ratio, of course, is yours to determine, but there are prizes for both the solving of programming problems and the drinking of drinks.

There are more rules than this,naturally, and you can find them at crashandcompile.com. They are the kind of rules that go like this: something happens, people take a drink. Also something doesn’t happen, or fails to happen as expected, and people take a drink. You get the picture, we think.

There are also ways to participate if you want to code without the drinking, or drink without the coding, or just distract the people trying to do both.There are prizes, and booze, and the satisfaction of proving that your skills can’t be thwarted by a little casual imbibing.

Follow the organizers on Twitter @crashandcompile and if this seems like your kind of party, get started on the training montage. We’ll see you there!

DEF CON in the Media: Mar Talks Art and DEF CON on PBS!

Posted 5.23.17

We put a lot of effort into the atmosphere of DEF CON. We bring in musicians and artists that set a tone of high-energy creative inspiration. One of our favorite artists is Mar Williams - you’ve seen Mar's bold and evocative work in the halls, in the programs, on your swag. That style and energy are a large part of the DEF CON image in recent years, and we’re very proud of Mar.

Mar recently shared some thoughts about the creative process and some ideas about the connections between hacking and art with an interviewer at PBS. Check it out and let it inspire you to just start something creative and see where it takes you.

If you find that you really like Mar's style and you need some more of it in your life, Mar has a Patreon account you can check out at https://www.patreon.com/spux.

YouTube version: https://m.youtube.com/watch?v=Ud-l6u9HzVY

Village Spotlight: BioHacking Village!

Posted 5.19.17

From the BioHacking Village website at defconbiohackingvillage.org:

"The DEF CON Biohacking Village is a multi-day biotechnology conference focused on breakthrough DIY, grinder, transhumanist, medical technology, and information security along with its related communities in the open source ecosystem. There have been multiple instances of DIYBio overcoming conventional science. We want to celebrate the biohacker movement with a compendium of talks, demonstrations, and a medical device hackathon.

The 2017 BioHacking Village theme is Medical Industry Disrupt. The Medical Industry is one of the last to be touched by technology. We have placed doctors and the study of medicine on an altar for years; the time of ivory towers, pedestals, and information isolation has come to an end. Biohackers are working on projects that have traditionally been kept in the labs of the medical institutions. We are moving science forward by working on DIY projects that matter and use citizen science to solve the economic problems that are caused by privatizing medicine and the resources for research."

If this sounds like your jam, or you just want to dip a toe in the DIYBio pool, you can find out more at defconbiohackingvillage.org, by following @DC_BHV or checking out their space on the DEF CON Forums.

Tuesday Feature: Better Know a Contest!

Posted 5.9.17

We're spotlighting some of the contests of DEF CON 25, to help you map your time and maybe get some practice in. Today's Featured Contest: COINDROIDS!

Coindroids is sort of an RPG, set in a post-humanity Earth where only financial services droids remain, battling each other through the ruins for upgrades and survival. Money is the goal, both as a symbol of power and the weapon from which power is derived.

The game is played within the blockchain, and each block represents a round. To attack, you send defcoin to the attack address. To defend, you send defcoin to a 'block' address to raise your shield. Gain experience, level up, purchase new and more powerful armaments and upgrades and claw your way up the leaderboard. Rule the Cryptocurrency wasteland.

For a thorough explanation of the game's inner workings, check out the coindroids github: https://coindroids.github.io/Coindroids-Documentation/#introduction

Sign up and get some reps in at the Coindroids website: def.coindroids.com

DEF CON in the News: Smithsonian Edition

Posted 4.20.17

The 2016 DARPA Cyber Grand Challenge was kind of a big deal. It was an autonomous, all AI Capture the Flag contest with millions of dollars in prize money.

Specialized Reviewers wanted
for DEF CON 25 CFP!

Posted 2.14.17

Greetz!

We're seeking specialized CFP Reviewers to join our DEF CON 25 CFP board this year. We have a fairly well rounded board, but we could use a few more to the team. Specifically, we'd like those more specialized in: Cryptography, Malware, Post-exploitation, Reverse Engineering, and Forensics. So if you can open a can of whoop ass with those skills, please apply.

All you have to do is write a cover letter telling us how you've been involved in the DEF CON community, what skills you can bring to the table, and where to find your resume. Please be aware being on the review board is a hard volunteer job. To review you need to spend hours reading submissions and providing feedback. There will be hundreds of emails, so you have to be committed. The reward, however, is having a hand in making DEF CON 25 amazing and the eternal gratitude of hackers all over the world. Which is nice.

Send your entries to talks@defcon.org if you want in.

Thanks,
Nikita

Luminous humans of the DEF CON community, we interrupt your slow news week to bring you this urgent message:

The DEF CON 25 CFP is OPEN! And so is the Call for Workshops!

We realize that's kind of two messages. The common thread is that the machinery of DEF CON 25 awakes from its fitful rest, and it hungers. It hungers for your talk submissions as well as your workshop ideas.

The time is upon us, people. The deadlines will arrive faster than you think. Get your stuff together, whip it into shape and get it in. We are only going to turn 25 once, and we want you to be a part of it.

DEF CON Speaker In the News

Posted 1.23.17

In 2013, the FBI wanted access to Edward Snowden's encrypted email. Faced with a request for Lavabit's  SSL key, founder Ladar Levison instead closed the service. Over 400,000 customers lost access to their accounts. Levison's hardline stance on customer privacy earned him praise from the security community.

Today the service is on the verge of relaunching. It's got brand new architecture, new features and soon, end-to-end encryption.

You can read Kim Zetter's interview with Levison on the Intercept.

For additional background , watch Levison and Stephen Watt discussing Lavabit at DEF CON 22.

DEF CON In the Media: Coded Web Series

Posted 1.18.17

The trailer for 'Coded', a new hacker-focused series from Freethink Media, has tons of shots from DEF CON 23. It also contains interview footage with Ladar Levison and Nico Sell. We've only seen the trailer, but It looks promising. Here's the promo blurb: "The data war is in full swing. Foreign governments are hacking major corporations, major corporations are collecting massive amounts of consumer data, and the NSA is listening to all of them. With malevolent hackers on one side and oppressive regimes on the other, data security is as important to the global economy and human rights as free speech and the rule of law. Join us as we profile a new generation of programmers helping consumers and companies alike protect their financial information, their identities, and their freedom."
