A DEF CON 25 Announcement

Thu, 15 Jun 2017 14:21:34 -0700


No DEF CON 25 Mystery Challenge or badge contest.

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

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

No special badges or challenge and no mystery challenge

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.

Yes, L0st had planned to do a special DC 25 challenge to break everyone's

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!

Thu, 15 Jun 2017 01:44:40 -0700

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

Village Spotlight: Packet Hacking Village

Sun, 11 Jun 2017 10:24:05 -0700


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, 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.

'Better Know a Contest’: Crash and Compile Edition

Tue, 06 Jun 2017 15:56:27 -0700


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 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!

Tue, 23 May 2017 00:27:09 -0700


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.

Village Spotlight: BioHacking Village!

Fri, 19 May 2017 18:41:50 -0700


From the BioHacking Village website at

"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, by following @DC_BHV or checking out their space on the DEF CON Forums.

Tuesday Feature: Better Know a Contest!

Wed, 10 May 2017 00:33:16 -0700


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:

DEF CON in the News: Smithsonian Edition

Thu, 20 Apr 2017 22:50:23 -0700


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. The systems competing were built by teams from all over the country, all of them building the road as they travelled. The teams that made it to the hotly contested final round are all full of straight-up wizards. We're proud of how great the contest turned out, and of all the brilliant humans who made it happen.

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.

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

Mon, 23 Jan 2017 13:18:23 -0800


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

Wed, 18 Jan 2017 15:01:45 -0800


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."

Announcing the DEF CON 25 Theme!

Fri, 23 Dec 2016 16:10:56 -0800

Greetings, hacker fam. It's time to announce the theme for DEF CON 25!

Welcome to DEF CON's Silver Anniversary!
We're celebrating 25 years of warranty-voiding, boundary-expanding adventures in technological subversion, and looking forward to the next 25.

The theme this year is 'Community, Discovery and the Unintended Uses of Technology' and the vibe is retrofuturist - think maxed-out 8-bit grafx in a dark arcade, lovingly defaced websites in Netscape Navigator. A world where adventurous digital misfits are building a new world out of the pixels and info the Powers that Be leave behind.

We've come a long way together, from the obscurity of BBS life to Runner-Up for Time's Person of the Year. From 20 people at the CON to 20,000. From media scapegoat to – well, it's a work in progress.

Join us at Caesars Palace to look back at how we got here, and to imagine together where we go next.

Connected Weapons: Warfare and the Future

Fri, 23 Dec 2016 14:12:53 -0800


According to CrowdStrike, the Russian hackers known as ‘Fancy Bear’ (recently in the news regarding the US election) or APT28 used a trojanized Android targeting app to geolocate and frustrate Ukrainian artillery.

From the article: “It’s incredible, from a technical point of view, that hackers and hacking can so drastically influence the outcome of military engagements,” Wardle said. “If this is all true, I mean, it would have been a huge, huge advantage for the Russians to be able to geolocate the Ukrainian artillery units...basically in real-time, via an infected Android app. Crazy.”

It’s worth noting that at DEF CON 23 Runa Sandvik and Michael Auger  dealt with the possibilities of using connected weaponry against its owners in their talk “Hacking a Linux Powered Rifle”. You can check that presentation out here.

IoT in the News: Through the Back Door

Wed, 07 Dec 2016 14:22:43 -0800


IoT-enabled botnets are all over the news, but the suspect devices are generally consumer-grade. In today's #internetoftriviallycompromisablethings update, 80 different industrial-tier IP cameras shipped with hard-coded creds, opening them up to all kinds of botnet mischief.

Sony has addressed the issue in the latest firmware updates for these devices, and updating is enthusiastically recommended.

Probably a good reminder that the higher prices for corporate-level gear do not imply better security practices.

If you want to devote some time to educating yourself on the current state of the Internet of Things, we suggest starting with the DEF CON 24 IoT Playlist.

Enjoy, share widely and run the latest firmware.

DEF CON Flashback Friday: Samy Kamkar's Drive it like you Hacked it

Fri, 18 Nov 2016 13:30:36 -0800


The new Raspberry Pi hotness is Samy Kamkar's PoisonTap. It's a cheap (like dinner at Arby's cheap) device that pops locked machines fast (like the onset of Arby's regret fast). Samy posted a video demo on YouTube, and you should watch it.

If you dig Samy's style and want to see another of his low-fi, hi-yield hacks, we've got a #defconflashbackfriday video for you - Samy demoing inexpensive car/garage door exploiter 'RollJam' at DC23 in supremely informative and entertaining fashion.

Check it out, pass it on.

DEF CON Speaker in the News

Thu, 17 Nov 2016 11:45:31 -0800

How to Overthrow a Government: Chris Rock at DEF CON 24

Tue, 18 Oct 2016 17:14:25 -0700


The US Presidential election is a few weeks away. Whatever the outcome it’s safe to say this election is an inflection point. Hacked communications, data dumps and claims of state actors using media to influence the vote have dominated the news cycle. These factors and the anxiety and outrage fatigue that acccompany them are likely to be around a while, so it seemed like an opportune moment to repost Chris Rock’s talk on overthrowing governments. It’s a thought-provoking investigation into what it might take to use the modern landscape for toppling a regime, and it’s a good practical alternative to the generalized hysteria promoted by cable news.

DEF CON in the News: IOT Village Findings and Stealthy Stego Vuln from DEF CON 24!

DC530 (Chico, CA) now meets every Tuesday!

Fri, 07 Oct 2016 14:04:00 -0700


From their Facebook page:

It's been a while since we posted an update, so this will be a doozy....

First and foremost, meetings are EVERY TUESDAY AT 7PM at Idea Fab Labs Chico! Every week people ask "is there a meeting tonight"? The answer is ALWAYS YES! Sometimes meetings are just 5 hackers hanging out talking shop. Come by and say Hi!

If you'd rather participate and get your hands dirty, there is currently a shiny voip phone running SIP firmware AND A PBX waiting for a config to be created and pushed.

The Kegbot also needs some love, as the raspi that runs the DB and Twitter feed is unplugged on top of the kegerator. Feel like getting the Pi and Tablet talking again? By all means!

There's also that sexy little black box on our table...but that's a secret. Right guys? See you next Tuesday.

Medical Device Security, and the Possibilities

Fri, 07 Oct 2016 14:02:53 -0700

Medical devices are back in the news cycle again, this time due to reports of a hackable insulin pump that can, under the right conditions, be made to deliver an overdose. That is scary, because the pump lives in your guts and not on the kitchen counter. In the end, though, it's also very similar to all the other IoT news: connected devices that aren't designed with security in mind are dangerous.

A more interesting thing about human augmentation devices like the. Insulin pump, however, is that they offer real, life-altering promise. Unlike all the devices clamoring to dim your lighting and save you from walking all the way over to the thermostat, this class of device can save your life, return your mobility, even make you a bootleg superhero.

For your Wednesday we offer a video from DEF CON 20 by doc/hacker types Christian Dameff and Jeff Tully meant to remind you of all the cool possibilities that the future holds, if we can get the security thing under control.

Link to the insulin pump story:

DEF CON Flashback Friday: Early Release from DEF CON 24!

Fri, 19 Aug 2016 14:46:24 -0700


Returning to the tradition of #defconflashbackfriday, we offer a presentation from all the way back in 2016 - Weston Hecker's 'Hacking Hotel Keys and Point of Sales Systems : Attacking Systems Using Magnetic Secure Transmission' from DEF CON 24.

We probably can't summarize the talk better than the title does, but if you need a little more incentive here's the abstract:

"Take a look at weaknesses in Point of sale systems and the foundation of hotel key data and the Property management systems that manage the keys. Using a modified MST injection method Weston will demonstrate several attacks on POS and Hotel keys including brute forcing other guest’s keys from your card information as a start point. And methods of injecting keystrokes into POS systems just as if you had a keyboard plugged into the system. This includes injecting keystrokes to open cash drawer and abusing Magstripe based rewards programs that are used a variety of environments from retail down to rewards programs in Slot Machines."

As always, watch, learn and share widely.

DEF CON 24 Contest Results are Live!

Thu, 18 Aug 2016 07:56:52 -0700


If the presentation tracks are the brain of DEF CON, then the contests are its heart. It's a kind of alchemy: we bring together thousands of interesting strangers fascinated with various aspects of technology, and we want them to leave a few days later with new friends, new skills and new obsessions. Our solution? Just add a rich, world-class layer of competitions run by an army of talented, insanely dedicated volunteers.

This formula has worked pretty well, and we thank all of you players for supporting the games and keeping the comp high-level and good-natured. It is our sincere hope that you're getting something valuable from getting into the DEF CON arena in the battle of your choice.

Still, the contests are as tough as they are fun, and the field is full of wildly brilliant humans. Every winner listed here has earned their prizes and bragging rights. We congratulate them all and hope to see all of you back in the ring for DC25.
