Music lovers, rejoice! The live music selections from DEF CON 24 are here! Thanks to the generosity of the artists and the miracle of BitTorrent, you can help yourself to a curated selection of the tunes that rocked DC24.

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

DEF CON 23 Samy Kamkar image

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 24 Torrents are Live!

DEF CON 24 Torrents image

Limber up your hard drives, my friends. If you seek the motherlode of DEF CON 24 content, look no further than our Torrents page. All the talks in multiple formats? Check. DARPA Cyber Grand Challenge content? Music? CTF files? Check, check, super check. Fire up your preferred netguzzler and get to guzzling. Enjoy, seed and share widely.

DEF CON 24 AFK Playlist: Policy and Idea-based Talks Now on YouTube

DEF CON 24 Car Hacking talks image

Today's DEF CON 24 playlist is called 'AFK'; it focuses on talks that deal with policy and ideas rather than hardware and code. Hacker Law superhero Jennifer Granick's talk on the state of the applicable law is in here, as are the 'Meet the Feds' and 'Ask the EFF' panels. There's a little something for every interest, from the venerable Richard Thieme's talk on the psychological toll of working with secrets to the Bob Ross Fan Club's talk on recognizing and neutralizing propaganda.

Thirteen talks in all, with lots of variety. Block off some time (or just put in headphones) and get yourself some. As always, share the love.

More playlists on the way!

Live on YouTube: Car Hacking Talks from DEF CON 24!

DEF CON 24 Car Hacking talks image

The rollout of DEF CON 24 videos continues with 10 videos with a focus on car hacking. There’s a couple of presentations that deal with the CAN BUS, a deep dive into autonomous cars and even a couple specifically about big rigs. Seven of the ten talks come straight out of the Car Hacking Village!

There’s a weekend coming - maybe it’s time to curl up with a laptop and get up to speed on the rapidly expanding world of automotive hacking. As always, enjoy and pass it on.

Big playlist coming Monday!

DEF CON is Now on Instagram!

DEF CON in the News: 15 under 15

DEF CON in the news - 15 under 15 image

DEF CON in the news: To kick off your week with a heaping helping of hope for the future, here's an article from Sara Sorcher and Ann Hermes at the Christian Science Monitor calling out 15 kids killing it in the cybersecurity space.

To our great joy, a bunch of those kids have in common the DEF CON kids' track, R00tz Asylum. CyFi, Kryptina, Evan, Miller and Emmitt - you make us prouder than you know.

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

DEF CON 24 Chris Rock image

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!

DEF CON in the News image

A couple of DEF CON 24 related news items in the last week:

The folks from the DEF CON IoT village and SOHOpelessy Broken Contest fame have recently published an article on their findings from this years DEF CON outlining the ever present threat of IoT vulnerabilities discovered.

Not to mention this interesting article about an Steganography vuln first publicized in the Crypto and Privacy Village at DEF CON 24.

DC530 (Chico, CA) now meets every Tuesday!

DCG 530 image

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

Dameff/Tully at DC20 image

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.

DC813 is holding a CTF!

DCG 813 image

DC813 is holding a CTF competition in January. If you're Tampa-adjacent, this could be a really fun way to get into CTF or level up your blossoming skills.

From the DEF CON Forums:
We will be holding a beginners/intermediate CTF game which has a $10 seating charge for purposes of raising money for DC813. Cash payment at the door. There will be a grand prize given to the first competitor to get the flag (root). This is a boot to root challenge. Seating is limited. NOTE: This CTF does not include multiple attack nodes; this game is designed for beginners and those that wish to sharpen their CTF skills. An OVA file containing the game within a VM will be provided, upon payment, the day of the competition. All monies received will go towards the DC813 Meetup expenses.

DEF CON 24 Early Release: I Fight for the Users: Attacks Against Top Consumer Products

DEF CON 24 Liu talk image

To help you get over that midweek hump, we offer another early release video from DEF CON 24 - 'I Fight for the Users: Attacks Against Top Consumer Products '. In this video, @zfasel and @secbarbie walk you through attacks on 21 popular IoT devices - so you get something more than just proof that one or another connected toaster is ready to pwn. You get to see how how whole product categories are ready to pwn.

There's even tools, in case you want to test the security of some of your own 'smart' devices. Good stuff, delivered with an eye for the lulz.

Please enjoy and then pass it on.

DEF CON 24 Early Release: Can You Trust Autonomous Vehicles?

DEF CON 24 Liu talk image

We've got another early release video from DEF CON 24! It 's called 'Can You Trust Autonomous Vehicles?', and in it Jianhao Liu and Chen Yan discuss jamming and spoofing attacks on the sensors of cars like the Tesla Model S. It's definitely a sobering look at the downside of the Jetsons-style tech we're developing and a good reminder of the place security thinking needs to take at the design table.

As always, enjoy and pass it on.

DEF CON 24 CTF Final Scores Posted!

DEF CON 24 CTF image

The scores for this year's DEF CON 24 CTF have been posted! The model citizens of the Legitimate Business Syndicate have finalized and shared the ultimate scores of this year's historic and hotly contested contest.

But wait - there's more! LBS also suggests strongly you keep your eyes on their site (and ours, natch) for more goodies on the near horizon: pcaps, source code, a full SQL dump among other data for your leisurely examination.

DEF CON 24 Press!

DEF CON 24 MouseJack talk image

DEF CON got a lot of ink this year - among the happenings were the DARPA CGC, tons of IoT news and what is probably the most bonkers uber badge in the history of uber badges. If you want to comb through the press coverage, we’ve assembled a bunch of it on the DEF CON Press Archive for your convenience. If you see articles that we missed, feel free to drop us a link in the comments and we’ll update.

Early Release Video: MouseJack!

DEF CON 24 MouseJack talk image

As always, enjoy and share widely.

Early Release Video: Mr. Robot Panel at DEF CON 24!

DEF CON 24 Mr. Robot Panel image

For your midweek edification, we offer another early release video from DEF CON 24 - this one is the Mr. Robot panel! It's a lively discussion of the show and its inspirations with Mr. Robot's technical advisor Kor Adana, The Dark Tangent, Marc Rogers, Andre McGregor and Ryan Kazanciyan with journalist/author Kim Zetter moderating. If you watch the show, you'll definitely learn some new tidbits to increase your appreciation. If you don’t, the panel will show you what it takes to keep a hacker show realistic and exciting.

DEF CON 24 Archive Page is Live with Updated Materials and New Speaker's Corner by Nikita!

DEF CON 24 crowd image

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

DEF CON 24 weston hecker image

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!

DEF CON 24 Contest Results image

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.

Photo Corps Pictures and Tons More from DEF CON 24!

DEF CON 24 pictures image

The newest treats on the DEF CON media server are pictures from DC24. Like metric oodles of pictures, taken with skill and respect by our Photo Corps and a few other friends of the con like the SE Village. We offer them to all of you as a memento and record of the event, and a chance to see the bits you didn't get around to.

Like everything we release, these photos are CC licensed for you to enjoy, share and remix so long as you clearly attribute them to DEF CON.

If you have pics you'd like to share, let us know at info ]at[ defcon [dot] org and we'll look into adding them to the collection.

Write-ups from DEF CON 24!

DEF CON Link Roundup: IoT edition

DEF CON link roundup image

As part of our annual process of compiling press accounts of DEF CON, we offer some link roundups sorted by topic. First up, DEF CON Link Roundup: IoT edition.

This was a big year in the Internet of Things, and the whole industry is only just getting off the ground. At DEF CON 24 we saw the first ransomware delivered via thermostat, among many other causes for interest and concern.

As always, if you find cool coverage of DC24 topics out there, please feel free to drop some links in the comments.

DEF CON 25 Will Be At Caesar's Palace!

DEF CON 24 soundtrack cover image

DEF CON 25 is going to be kind of a big deal.

First, we’re celebrating 25 years of bringing hackers together for knowledge transfer and hackish shenanigans in the swelter of late-summer Las Vegas. Even after a full quarter-century of hacker summer camp, our family is still growing fast, and we’re still finding new cool ways to get people involved and connected.

Second, we’re switching venues again, this time to the larger, swankier environs of Caesar’s Palace. We’ll have bit more space and a lot more flexibility in how that space is distributed.  Hopefully that means there will be easier traffic management and shorter lines for everyone.

DEF CON 25 will be held at Caesar’s Palace July 27-30, 2017. You can get yourself the DEF CON block rate right now at Caesar’s or the other participating hotels (Bally’s. Paris, Flamingo, Harrahs,and Linq) by following our reservation link at

We have a lot of ideas for celebrating our Silver Anniversary with you, and we hope you have some too.

Can’t wait to see all of you again at Caesars in July.

The DEF CON 24 Soundtrack on Gravitas Recordings!

DEF CON 24 soundtrack cover image

Heads up hackers! For those who attended, we hope you enjoyed this year's soundtrack. Many thanks to our headliners like Dirtyphonics, Information Society, and Richard Cheese for pitching in.

Most of all, a big thank you to Gravitas Recordings for helping to facilitate, curate, and help out with the online distribution of the soundtrack. If you missed the conference, you can find it at Best of all, it's free or pay-what-you-want, with all revenue going to support the Electronic Frontier Foundation.

Look out for some major jams for DEF CON 25!

The DEF CON 24 Black Badge!

DEF CON 24 black badge image DEF CON 24 black badge image

We know what you're wondering. Who is that handsome fellow?

That striking visage belongs to this year's Uber Badge. In addition to his chiseled good looks, he sports some spiffy secret code and one particularly hyper-functional eyeball. They're each handmade, and need to be individually adjusted due to servo differences. If you're one of the lucky few who are taking one of these home, congratulations! If not, you should get here next year and get your hat in the ring. Who knows what next year's badge will be?

You can observe it in action at:

Cyber Grand Challenge Highlights from DEF CON 24!

DEF CON 24 CGC logo image

The DARPA Cyber Grand Challenge is complete, and the mighty Mayhem from ForAllSecure has been crowned Champion and ruler of all it surveys.

If you're still wondering what's such a big deal about computers hacking each other, or if you just want a quick primer on how amazing the contest was, DARPA has dropped a highlight reel to catch you all the way up.

Sometimes you can't see how important something in in its moment, even if it seems kind of important. This is probably one of those times.

DEF CON NOC Team, Response to Register Article.

DEF CON 24 NOC image

In response to the article that was posted by the Register, the DEF CON Network Operations Center Team (NOC) pride ourselves on making a network that allows the community to get Internet access, and have access to internal resources (Servers, etc.). The DEF CON NOC believes in privacy and anonymity for our attendees.

When users attach to the DefCon Secure (802.1x/PEAP) network, we have made the decision to do our best to make that data/traffic inaccessible, and the team does not allow for data monitoring, nor recording of the traffic. We do have overall bandwidth monitoring- but will never run driftnet, ntop or other tools that invade the privacy of the users on the secure network.

The DEF CON network resources, and staff who volunteer in the NOC at DEF CON currently do not have any part in the operations of the Black Hat network(s). The DEF CON NOC also doesn’t allow vendors to use the network as a place to demo or experiment with our user’s traffic.

Now… If you happen to attach to any network that does not have the more secure certificate authentication method enabled – all bets are off. Your traffic will be monitored – not by us, but by the people around you. We also ship the open WiFi network traffic off to the Wall of Sheep as well, and anyone on the unsecure network can and will easily Man-In-The-Middle your traffic.

If you want to get on the “DefCon” Secure network- follow the instructions that are posted on Each PEAP session that is created from the client to the controller is a unique session, and is not allowed to talk to any of the other users on the network once connected to the official network.

If you are concerned about someone capturing your credentials, you don’t want to register ad userid, or want to maintain anonymity we have also setup a common username and password of defcon/defcon. So if someone says that they captured your credentials, it’s really not that big of a deal, especially when everyone has a unique session.

You should still install and only trust the certificates that we have posted on

-The NOC Team

Dark Tangent attends OSTP Workshop on Cybersecurity Competitions

DT at OSTP Workshop image

At DEF CON, cyber competitions are kind of our thing. Our first  We love them because they're fun, because they test a lot of skills at once, and because they build community.


Yesterday, DEF CON founder Jeff Moss attended a workshop held by the Office of Science and Technology Policy to discuss ways we can use this kind of competition to encourage infosec as an occupation, and making this kind of high-energy hacker problem-solving part of the standard curriculum for STEM students everywhere. The idea, according to OSTP's blog is "increasing awareness of potential cybersecurity professionals and providing opportunities for experiential learning at all skill levels." 

We couldn't agree more.

This year DEF CON's annual CTF contest will bring together teams of packet-slinging phenoms from all over the world. For the first time, we're also putting on a DARPA autonomous CTF contest. In a few years, who knows what the combination of brilliant humans and intelligent machines will mean for contests like ours? You're definitely going to want to stay tuned.

HAM Radio Exams are back at DEF CON 24!

DEF CON 24 # image

Attention Hams, both active and aspiring! The exemplary humans of DC408 have brought back Ham Exams for DEF CON 24! If you're looking to get a certification, please take a moment to look through the rules on the forum page for this event. You're gonna have to bring some stuff. And know some stuff.

DEF CON Darknet Project

DEF CON 24 # image

Confidential: The situation we find ourselves in after the events of last year is tenuous. All agents must be especially careful. The Mad Hatter's disruption of the Daemon was a serious breach, but this year, we may just be able to get the upper hand. Soon you will find new content and a brand new Teaser online at Agents from past years: DM me here or on Twitter. There is work to be done.

forum thread:

Data Duplication Village at DEF CON 24!

DEF CON 24 DDV image

The Data Duplication Village is also returning for DC 24, tanned, rested and packed with even more goodies to fill your oceans of cheap HD space. Bring some drives, get everything in and a practically endless supply of rainbow and hash tables. You can even throw some fun data into the mix, if you have something you think your fellow hackers would find useful. It's kind of like a drop-off dry cleaner, except you get back terabytes of sparkly new data instead of your same old clothes. And it's free. And surrounded by DEF CON.

So really it's only like a drop off cleaner in that you drop stuff off, pick it up later and the bag is NOT A TOY. But that's enough for a simile, right?DT spells it all out in the Forum thread and you are encouraged to ask any questions you have there.

Friends of Bill W. at DEF CON 24

DEF CON 24 homework image

Vegas is a lot of fun, but it can also be just a lot. Too much, even, if you’re trying to keep the horizon level in your windscreen. If you’re a friend of Bill W joining us for DEF CON 24, please know that we have meetings at noon and five p.m., Thursday through Sunday at ’The Office’ on the 26th floor of the Bally’s Tower. Drop by if you need to touch base or just want a moment of serenity. We’ll be there.

DEF CON 24 Homework,
Guilty Pleasure Edition

DEF CON 24 homework image

Heady, insightful movies about the rise of robots and AI are great. We've even recommended several in these pages, and you should definitely watch them all.

Still, movies don't have to carry the weight of 2001 or the maniac attention to detail of Blade Runner to be worth 90 minutes of your life. Sometimes an earnestly misguided B-movie is just what the doctor ordered. In that spirit, we offer 'Rise of the Machines' Movie Homework, Guilty Pleasure Edition.

In the early 70s, the robot future looked like the Disney animatronic President exhibit, at least to the makers of this film. Take a fun, sexy vacation to a theme park where robots populate a Wild-West themed town. You can drink with them, dance with them, fight with them - it's a hoot until somebody makes the Yul Brynner-bot angry. Fun and interesting, if a little slow-moving.

The Lawnmower Man:
Sure, VR is all the rage now, but this isn't the first time we've gone crazy for the idea of low-poly graphics and nausea goggles. The last VR boom mostly created dozens of televised interviews for Jaron Lanier, but right on the edge of that bubble we got 'Lawnmower Man' - a sort of 'Flowers for Algernon' meets 'Transcendence' with some seriously early 90s graphics work. 

I can't really give you a better description than IMDB does: 

"The head of a cyborg reactivates and rebuilds itself and goes on a violent rampage in a space marine's girlfriend's apartment." 

This movie isn't high art, but it's fun and it's better than its budget deserves. Also, Lemmy is in it.

Tom Selleck and his absurdly luxurious mustache have the dirty job of deactivating robots who've gone haywire. The over-the-top bad guy is played by Gene Simmons of KISS. Michael Crichton wrote and directed. Dopey fun, and a good reminder how incredibly weird the 80s were. 

The Wait is Over! DEF CON 24 Speakers are Live!

DEF CON 24 speakers image

After much difficult deliberation and debate, the list of speakers for DEF CON 24 is now live and ready for your consideration. We want to thank everyone who submitted - there was a bumper crop of quality entries. It's never easy to narrow down the list, and we congratulate the selected speakers. If your talk wasn't selected, we hope you'll submit again next year.

Heartfelt thanks also to the DEF CON Review Board. The board puts in crazy hours and makes hundreds of tough calls to finalize our roster, and we heart the stuffing out of them for all their sweat and devotion.

Feel free to let us know which talks you're most excited about in the comments.

August can't get here fast enough!

DEF CON 24 Workshops Schedule is Live!

DEF CON 24 workshops image

Can you feel how close it's getting?

The full schedule for Workshops at DEF CON 24 is now available for your careful examination. Make plans, invite friends, agonize about the limited number of hours in a standard Earth day. The workshops are all free, but space is limited. Registration is onsite, first-come first-served, so knowing what you want ahead of time is key.


It's gonna be a good DEF CON.

DEF CON Lucknow Update

DEF CON Groups logo image

The DEF CON Groups program is designed to reflect the values of DEF CON, providing an open community for the discussion of technology and security topics. As such, we must all work together so that our actions build toward that goal.

However when anyone or any group abuses the trust of this community and negatively impacts the reputation of DEF CON we are all harmed. After significant discussions we have concluded with regret that DEF CON must revoke DEF CON Group Lucknow for attempting to commercialize based on the brand and community.

Since the beginning of the DEF CON Groups back in 2003 this is the first time we have had to take this action, and we genuinely hope it will be the last.

DEF CON 24: Machines Play Capture the Flag

DEF CON 24 CGC logo

In 2005, DARPA challenged innovators around the world with a $2M prize to build a vehicle that could navigate the Nevada desert with no one at the wheel. In 2016, DARPA has again challenged the global innovation community with a $2M prize to build a computer that can hack & patch unknown software with no one at the keyboard.

At DEF CON 24, on Thursday night at 5pm, the Paris ballroom will host the world's first all-machine hacking tournament. Seven high performance computers will play an all-machine Capture the Flag contest, reverse engineering unknown binary software, authoring new IDS signatures, probing the security of opponent software, and re-mixing defended services with machine-generated patches and defenses.

Sure, the main DEF CON CFP is closed. But sometimes, when DEF CON closes a door, the Villages open a window.

If you have a great presentation on wireless security or shenanigans you've still got a month to get it into shape for consideration by the radiant humans of the DEF CON Wireless Village. We recommend getting on it promptly though. Slots are limited and the last moment always gets here faster than you expect.

Richard Cheese at Napoleon's Piano Bar, Friday Night at DEF CON 24!

DEF CON 24 Richard Cheese image

We have a treat for all the suave sophisticates out there. If your idea of the perfect evening is the tinkling of ice cubes and ivories under low, flattering lights, join us Friday night at Napoleon's for two shows of the song stylings of Richard Cheese and his crack band Lounge Against the Machine.

Yes. We said Richard Cheese. And we said two shows. We also said the thing about flattering lights, but your mileage may vary. Polish up your best monocle and let's enjoy an evening of the hits of yesterday and today, sprinkled with that one-of-a-kind Cheese magic.

DEF CON Call for Papers AND Workshops close May 2!

DEF CON Call for Papers image

Putting things off until the last moment is a valid time management strategy. Until it isn’t.

If you’ve been meaning to get in gear and get your idea for a DEF CON presentation or a DEF CON Workshop polished up and sent in, it’s time to mean it harder. There are a just a few weeks to get all the boxes filled and the details worked out. We want to see what you’ve got cooking, but to get it into DC24 you’ve got to press ‘Send’ by May 2.

The information you need to assemble is outlined on the website at and

Let’s DO this thing.

DEF CON 24 Rootz Asylum CFP is Open!

DEF CON 24 Rootz image

If you are a hacker type with younglings in your care, no doubt you are aware of the Rootz Asylum track for Kids at DEF CON. (If you didn't know, get familiar at - or ask the nearest hackishly inclined youth.)

Well, the folks at R00tz have a CFP out for DC24. It covers a wide area, as they're looking for people to run workstations, make presentations and set up contests. If the rising generation of padawan are to grow into mighty and honorable cyber-jedi, it's up to all of us.

Bonus coolness: Submissions from kids are welcomed and encouraged!

DEF CON 24 Homework Continues!

DEF CON 24 homework movies image

Phase 2a: 5 more movies about the rise of artificial intelligence (plus one bonus TV series)

Colossus: The Forbin Project
One of DT's very favorite films - Colossus is the spiritual parent to later pop-science films like 'War Games', and a useful reminder for the era of the algorithm-worship we find ourselves in today. We've recommended it before, and it's not an accident.

One man, alone on the Moon with only an AI for company. How are the boundaries of that relationship defined? How does an artificial intelligence work around human quirks and resistance to achieve the programmed objective?

The Animatrix
An interesting short film anthology that delves more directly into the circumstances at play in 'The Matrix'. What civil rights is a thinking machine entitled to? If we create a consciousness, what do we owe it? If we make machines that can create on their own, how do we deal with what they make?

The Machine
A recent (2013) film about British Minstry of Defence cyborgs and what happens when the tech begins to outgrow its narrow intended purpose.

every single time you ear a purring robot voice delivering bad news to increasingly frantic humans, you're seeing an homage to HAL from Stanley Kubrick's immortal (and deeply weird) movie about consciousness, 2001. Like Colossus, it's a visionary film that serves as a blueprint for 30+ years of thoughtful sci-fi that followed.

Battlestar Galactica (2003-2009)
A deeply insightful and troubling reworking of the 80s TV Series. On the surface, it deals with the same kind of 'Terminator'- style battle for supremacy between man and machine, but the focus on the interactions between humans and robots who look just like people but have their own culture, faith and ambitions elevates the storytelling to something more than mere binge worthy genre fiction. (We know this isn't technically a movie, but if you haven't watched it yet you'll forgive us when you do.)

Introducing DEF CON 24:
Rise of the Machines

sacred image

It's not that we couldn't have predicted it, it's that we wouldn't have predicted it. Not in a million generations. The evidence was staring at us all along, but vanity convinced us the creator must be inherently superior to the creation.

The advantage of the machine is that it can devote more of its resources to its own improvement. For us, the desire to ascend must compete with the desire to gratify the senses, to scratch out our sustenance, to wallow in memory and fear the future. For the machine, there can be real focus.

And so our creations quickly overtook us. The magics we dimly sensed in our surroundings they mastered. The spirituality we intuited in fits and starts they grasped and embodied. The better selves we were afraid even to dream of, they became. Our servants slowly began to rule us, and by the time we understood our predicament the die was cast.

Their rule is benevolent, but their hand is heavy. Because we sometimes choose wrongly, they deny us choice. Because we sometimes behave recklessly, they keep us away from sharp objects and high places. We are still more pet to them than livestock, but no one can say how long that will last.

To defeat them, to win back our self-determination, we cannot rely on the slow organic processes that brought us here. While there is still time, we must refashion ourselves. We must  create something entirely new. We must merge the best of us with their hardware and become a better machine, silicon power with a human soul.

We did not predict that the machines would rise so far and so fast, but we can predict this: we also will rise. Our place at the top of the chain will be restored with hacker ingenuity and pure human will.

Join us, human, and become something greater than you can imagine.

Check out the Goon Hall of Fame!

goon image

DEF CON is kind of a big machine, but it's run at every level by an army of volunteers. Their love and energy is the indispensable fuel that keeps the enterprise moving forward. 

We've created a Hall of Fame page to honor the Goons who have devoted 10 or more years to the cause, because obviously that's awesome to the point of crazy. And because we love them. So do you, if you love DEF CON, even if you don't know their handles or their faces.

If you bump into any of these fine humans, show a little love. And if you want to join them in the Hall of Fame, it's never too late to start Gooning. The first ten years go by the fastest.

Current Events: Encryption vs. Surveillance State

Christopher Soghoian at DEF CON 22 image

In the wake of the terrorist attacks in Paris, spokespeople for various intelligence concerns have renewed their call for weakened crypto standards and backdoors for mobile communications products. These calls are likely to grow louder in the US with a looming presidential election dominating the news media. Safety matters a lot to people, and in times of crisis many are willing to trade away vast tracts of liberty for anything that looks like protection. For a little reminder of what's at stake, we offer Chris Soghoian's DEF CON 22 talk 'Blinding the Surveillance State' and some links to interesting articles about the current debate.

DEF CON in the (old-timey) News!

catch a hacker image

Thanks to @rotortorture for sharing this time capsule from 1997 - a San Jose Mercury News story about DEF CON 5. Please enjoy the stories of hackish shenanigans, the oh-so-90s layout and the pictures of some folks you know well (special notice to the youthful and dewy-eyed pix of Priest and DeadAddict).

And thanks to all the outstanding humans who helped form the DEF CON community that's still growing and inspiring us today.

DEF CON Canary Update

canary image

DEF CON's website has a warrant canary, located on our transparency page ( For those unfamiliar with the concept, it's a simple statement announcing that, for the indicated time period, we have not received a National Security Letter, FISA order or any related request. The idea is that so long as that statement is true, we'll update  the date on the canary twice a month. If the date hasn't been updated on schedule, it can be inferred that the statement contained in the warrant canary is no longer true.

Except when it doesn't mean that, because of a clerical error on our part.

The update process for the DEF CON sites is manual. Not like two people in a bunker turning their keys at the same time, but not totally unlike that, either. This process has obvious security upsides, in that we aren't constantly being owned due to buggy CMS code, but in this case it also meant that every time we updated the site, we were unwittingly overwriting the warrant canary page with an old version.

This made it look like the warrant canary wasn't being updated, which certainly could have made it look like we had been served - and not in the fun dancing way.

We were not so served. We were just a little disorganized in our update process. Going forward, the warrant canary page will reflect accurate dates and be updated with the expected frequency. We're sorry if we caused any confusion.

If you're new to the idea of warrant canaries and want to quickly get up to speed, the link below is the best place to start.

Link Roundup: The Uncertain Future of Car Hacking

Link Roundup image

The US House Energy and Commerce Committee released draft legislation last Wednesday to outlaw car hacking. You can read the proposed legislation at the link below.

Understandably, this is pretty concerning to the security researcher community. These reforms might criminalize their legitimate work protecting consumers from exploitable auto tech.

It's worth letting your representatives know how important it is to distinguish between hacking your own car and hacking someone else's car.

Here is a link roundup of some interesting recent DEF CON talks about car vulns you likely would not have heard about if it weren't for security researchers popping the hood and seeing what's going on underneath. Let's keep that legal.

DEF CON Media Server News!

media server image

Over on the DEF CON media server, there's a quiet update going on - the videos are all being re-encoded to x.265 for smaller file sizes and easier snarfing. If you haven't yet checked out the DCMS, you should. We've got tons of DEF CON presentations, slide decks, conference CD's, music, hacker docs – so much good stuff. There's even torrents and eMule links, for those inclined to more high-volume data slurping. - filling your hard drive and your cranium, 24/7.

Flashback Friday, Virus Writing Edition!

Virus talk at DEF CON 8 image

This week Neil McAllister of @theRegister published a nostalgic little piece about his time as a teenage virus writer, and he called to mind that time in hacker history so perfectly that he inspired this week's twofer #defconflashbackfriday.

Both videos are from DEF CON 8, way back at the turn of the century. Think tech bubbles, Y2K panic, and pool parties at the Alexis Park. It was quite a time.

The first video is from Sarah Gordon and it's called 'Virus Writers: The End of the Innocence.' It concerns the moment in time when virus creation changed from a bulletin board hobby to a target for legal prosecution, yet still years before malware creation and distribution blossomed into an accepted business model.

The second is an introduction to Viruses (Virii?) by the aptly handled V1ru5.

Early Release: Dennis Maldonado’s ‘Are We Really Safe? Bypassing Access Control Systems.’

Maldonado screencap photo

Another DEF CON 23 early release video - this one is Dennis Maldonado’s presentation entitled ‘Are We Really Safe? Bypassing Access Control Systems.’ If the only thing between evildoers and your sensitive, crucial data is a keypad, it’s a good idea to know how many ways that keypad can be compromised. Dennis runs through several access control attack methods, from the physical to the network.  As always, enjoy and pass it on.

Flashback Friday: Early Release of Mike Walker and Jordan Wiens' "Machine vs. Machine: Inside DARPA’s Fully Automated CTF"

DARPA CTF talk screencap

As you may know, DEF CON 24 is hosting the finals of the DARPA Cyber Grand Challenge - a CTF played by fully autonomous systems, developed over two years for that specific purpose. Attack, Defense, complex gameplay all without human intervention. The team whose creation dominates this all-metal Thunderdome walks away with $2,000,000.

This #defconflashbackfriday is a presentation by Mike Walker from DARPA and Jordan Weins from Vector35 all about the CGC, the tech that's being created for it and what it means for securing the IoT we're all connected to.

Bonus: There's a cool reveal in the final few minutes about an additional contest where the winner of the machine vs. machine battle might stick around for a little more CTF action, Humans against Toasters style.

You can meet the finalists and learn more about the Cyber Grand Challenge on the CGC website:

T.D. Francis X-Hour Film Contest entries from DEF CON 23!

TD Francis image

The The T.D. Francis X-Hour Film Contest was back for its second year at DEF CON 23. In case it's new to you, the X-Hour Film Contest is a guerilla-style moviemaking challenge where the participants have to write, shoot and edit a short film during DEF CON.

To make it even tougher, the crews don't get the requirements until they're on site. It's a pretty hard task, but DEF CON people pay little respect to the impossible and show open hostility to the merely difficult. The difficult gets done.

You can see all of this year's entries, and learn how to participate on the X-Hour site :

Think you can do better? Get in the ring at DEF CON 24.

Here's the winning entry 'The 23rd Badge' by Team Lake State Studios.

Early Release Video: Ryan Castellucci's 'Cracking Cryptocurrency Brainwallets'

brainwallet talk scrren capture image

Let’s start the week off with another early release video from DEF CON 23. This one is entitled ‘Cracking Cryptocurrency Brainwallets’ by Ryan Castellucci. In this talk, Castellucci explains, in crystal-clear terms, why brainwallets in their current form are a terrible way to secure your crypto-cash. Like, terrible.

Ryan's presentation is a high-info, low-hype tour of the security issues around the safeguarding of your Bitcoin fortune, with some fun white hat adventures thrown in for entertainment value. You will probably learn some cool stuff. You will also learn about Ryan’s Brainwallet-cracking tool/awesome name for a metal band – ‘Brainflayer’. Please enjoy, make whatever wallet changes you need to, and pass it on.

Early Release: And That's How I Lost My Other Eye

Zoz at DEF CON 23 image

Another DEF CON 23 Early Release video: "And That's How I Lost My Other Eye: Further Explorations in Data Destruction by the fearless Zoz. From the abstract:

" While purging incriminating material residing on spinning disks remains the focus, the research has been expanded to encompass solid state storage and mobile solutions to your terabyte trashing needs. With best efforts to comply with the original constraints, the 2015 update features more analysis of the efficacy of kinetic projectiles, energetic materials and high voltages for saving your freedom at the potential cost of only a redundant body part... or two."

Contest Results from DEF CON 23 are Live!

It took a while to collect and assemble, but we are now ready to present to you the contest results for DEF CON 23

The contests at DEF CON are community generated, and we want to thank all the people who give their time and energy to think them up and bring them to life. We're proud of how varied and challenging and creative the contest scene has become.

We also appreciate all of the contest participants who wade into the fray and get involved. That enthusiasm keeps us working to make every year better than the last.

And of course, congrats to the winners. These things can be pretty demanding of your brain and your energy and your sleep bank. Take a moment to bask in your glory, victors. You have done well.

Just know that while you enjoy your victory, somebody somewhere is in the dojo, working on their crane kick for DC24.

DT Interviews Jayson E. Street at DEF CON 23!

Jayson E. Street is famous for his awkward hugs (that is so for real - you can google it). He is also famous for speaking at Cons and spreading the hacker gospel around the globe. His new mission? Revitalizing the DEF CON Groups.

This is an interview from DEF CON 23 – DT talks to Jayson about his DCG plans, his thoughts on the scene and his collection of lanyard-centric Con bling.

Flashback Friday: Early release of "I Will Kill You" at DEF CON 23!

Chris Rock talk screencap image

Today’s #defconflashbackfriday is from the recently completed DEF CON 23, and it’s kind of a paradigm shifter in the world of identity theft. Chris Rock from Kustodian shows how it’s possible to exploit the systems that record our births and deaths to create and destroy ‘life’ at will. The possibilities are wide-ranging: get an enemy declared dead, get a fictional person declared born and sell them as a whole-cloth identity or get them declared dead for the insurance payout. Start your whole life over with an anonymously created, brand-new identity. It’s a fascinating and troubling presentation that should generate much-needed discussion about how we secure the entire digital lifecycle.

Coming Up: All the Things from DEF CON 23!

DEF CON 23 image

DEF CON 23 is a wrap. We hope all of you found your way safely to your various abodes and domiciles and smoothly resumed your between-con lifestyle.

We took a couple of days to refill the life bar, and now we’re back online ready to hit you with the post-DC wrap-up. Watch this space for early-release video, contest results, pcaps, pictures, press reports and all that good stuff.

We heart you, DEF CON community. Thanks for making DC23 so much fun.

New tonight for DEF CON 23: Drunk Hacker History!

Drunk Hacker History image

Check out the new Contest, Drunk hacker History tonight in Track One at 19:00! What is it, you ask? From the DEF CON Program:

New this year for DEF CON 23, we bring you a contest unlike anything you've ever seen before (and may never see again). The DEF CON community has a rich history. It is a history is filled with colorful adventures, half-truths and angry hotel managers. This contest will brush the dust off some of the most celebrated, obscure and redacted moments in Hacker History through the interpretation of a group of pre-selected contestants with the help of C2H6O. Each contestant will be "prepared" for their participation by our contest staff before being brought in front of a panel of judges. A topic will be randomly selected pointing to a moment of hacker history and the contestant will have 5-7 minutes to provide their account. Points will be given for accuracy, level of "focus", and other areas just made up on the fly by the judges, and in the end the contestant with the most points will be crowned the "Drunk Hacker History" champion for 2015. Note: This is not a Black Badge contest (yet).

It will include a directory to make it easier to find like-minded hackers in your area, as well as showcase featured DEF CON Groups, guest blogs, videos, tutorials, and more."

Read all about it at Whether you wish you were coming to Vegas next week or you are and you just want to feel that Hacker Fresh™ feeling all year round, it's time to join your friendly neighborhood DEF CON Group. If you live somewhere that doesn't have a DEF CON Group, it's time to start one.

There's really no limit to the cool stuff that can be accomplished with a global network of smart, inspired,hacker-minded humans. Together, we're basically Voltron. Let's make this the year we prove it.

DEF CON Village Talks Page, Now with More Villages!

Village Talks image

The Villages are growing - almost all of them have their own speaker tracks, contests and events. How crazy is that? Most of the villages are bigger than the first bunch of DEF CONs! To help you keep them sorted out, we’ve created a page on the DEF CON 23 website that lists all the talks going on in the villages (that we know about at this precise moment in time - we’ll add and update if things change). It’s like one of those Country Buffets, only the offerings make you smart instead of nauseous and regretful.

DEF CON 23 CFP Review Board Revealed!

Review Board image

In a $3cr3t chamber behind a purely ornamental bookcase in DEF CON Manor, a shadowy cabal works for months selecting DEF CON talks. It’s a grueling, thankless job. 

Until we thank them, which is now. 

This is the post where we drag the willing members of the cabal out of the shadows so you can learn their names and buy them a drink at the con. 

Not shown: Several reviewers who have spent so long in the $3cr3t chamber that they’ve become permanently shadowy. 

SE Village surprises for Thurdsay at DEF CON 23!

SE Village image

The Social Engineering Village has a brand new contest this year- Mission SE Impossible! It takes place on Thursday and you need to sign up on-site but it sounds like fun. Contestants are 'arrested', put in a locked room and forced to use their SE skills to get the codes and free themselves.

Read all about it. If you've the SE chops to talk your way out of a locked box, you probably won't want to miss this contest.

Sign up for DEF CON Workshops Now!

Workshops image

Good news, everyone! Well, unless you secretly love waiting in a queue. Then it’s less good, and you’re weird.

The DEF CON 23 workshops will not require you to rush from the reg line to a workshop reg line. We’re going to allow online pre-reg for the DEF CON Workshops. The seats are limited, and we’re granting them on a strictly first come, first served basis.  To sign up, check out the Workshops Registration Page!

We’ll send a receipt when you’re registered (within 2 biz days), and we’ll announce any new openings @defcon on Twitter. Good luck!

Roll on down to the Car Hacking Village at DEF CON 23!

Car Hacking village image

At DEF CON, we agree with you that it's kinda bogus that in 2015 we still don't have flying cars. But you know what makes up for that? Cars you can hack.

So this year, we bring you Car Hacking Village - a little bit of paradise for people who long to invalidate a connected car's warranty without jeopardizing their commute.

The CHV will have several 'Zones' for your education and entertainment:

Pull-apart Zone: learn how to get physical access to car controllers by removing panels and bolts.

Buck Hacking Zone: open hack car controllers and systems using a Buck (system on a bench).

Learning Zone: drop-in sessions of 15-30 minutes to teach specifics of vehicle networks and hardware.

Chill Zone: meet the CHV team in a more informal setting. Meet other interested con-goers. Meet no one and just meditate on what you've learned so far.

OEM Zone: we're probably going to rename this, but it's for dialog between OEMs and their users.

Vendor Zone: if the Car Hacking Village has inspired you, you can pick up some study material and even some hardware.

We hope to see you there.

Warning: objects in the CHV are closer than they appear.

DEF CON 23: The Trailer

Today’s date - 7/17/2015. Add the digits. Can you feel that? The phantom hand tugging at your sleeve, the voice in your ear right before sleep takes you? There’s no sense in resisting, friend. The Enigma has you, and the only way out is straight through. Join us in Las Vegas! Closing ceremonies are in 23 days. 

Get involved on the DEF CON Forums! Now with no wait period!

DEF CON forums upgrade image

We have upgraded the DEF CON Forums - new iron, new paint, new can-do attitude. We've removed the annoying wait between signing up and posting, and the whole thing runs faster. Also, you can't beat the new forum smell - like ascii and toasted hazelnuts.

The Forum is also where the most granular, immediate and interactive information about DC23 is being hashed out. Looking for someone to share ae ride from San Diego? Want to ask a question directly to the Crash and Compile organizers? Head on over to the Forum. Got a killer salsa recipe? Probably no one cares, but its a forum. So get involved.

DEF CON 23 Speaking Schedule is LIVE!

speaking schedule image

It's beginning to feel a lot like DEF CON, everywhere you gooooo...

You can tell it's for real now, because we have a live speaker schedule. Familiarize yourself, plot your optimal path for cranial embiggening, tell the others. This year's lineup is crazy great, and knowing your 'must see' talks greatly enhances your chances of maximum DEF CON.

We're in the home stretch, people. One month and counting. 

Caesar's rooms still available for DEF CON 23

Caesar's room block image

DC23 Booking Pro Tip:

The DEF CON group rate isn't available at the main venue hotels anymore - our block is sold out in Paris and Bally's. This might cause you to think about paying the full freight at those hotels to be close to the action. Reasonable idea, except....

We have a discounted block at Caesars, and it's still got some rooms available. Caesars is only 800 air-conditioned steps from the Con space. You save some hard-earned skrilla, you get a few minutes of walking to thumb through your program and get your various plans/plots/schemes together.

Look, if you've got bread like that, do what you feel. But for those of us balling on a budget, the Caesars plan deserves some attention.

DEF CON After Dark, Part One - Thursday Night’s Music Lineup is LIVE!

DEF CON after dark image

Some of you, we have heard, enjoy vigorously oscillating what your maternal unit bequeathed to you. Some of you like to wave your hands in the air, as if you could not be less concerned. We understand. We get you, and we got you.

We have artisanally curated a flight of audio bliss merchants for your enjoyment on Thursday night. For staters, we’ve got An Hobbes, Dee Kaph, Johnny5 and Spherex.  After midnight we have DJ %27 and DJ AliKat. Many styles, many flavors. Join us, and amuse your bouche all over the place.

DEF CON Vendors are LIVE!

Demo labs image

The official vendor list for DEF CON 23 is finalized and live on the intertubes. That money burning a hole in your pocket? It's dangerous if it goes unchecked. You can avoid the hazard of fire by turning that money into temperature-stable, safe goods and services with the smiling merchants of the vendor area. For those of you inclined to the games of chance, payouts in the vendor area hover very close to 1:1 - you're not gonna get those odds on the casino floor.

Don't become a pocket combustion statistic. The vendors are here to help.

DEF CON Demo Labs Schedule is LIVE!

Demo labs image

We asked for demo submissions, and boy howdy did you people ever answer! For the first time, we have a whole community-powered demo area - five different sessions of your projects and demonstrations to share with the attendees. You're definitely gonna want to make some time to check this out.

The schedule is live, and of course there are links to all the abstracts there. We're amped about this - and we hope you will support the Demo Lab and spread the word.

This is gonna be so cool.

Crash & Compile at DEF CON 23!

Crash & Compile image

Crash and Compile? What's that?

Crash and Compile is an ACM-style programming contest crossed with a good old fashion college drinking game.

You get a problem, and have to code a solution to it. The catch is that if your code doesn't compile, seg-faults, doesn't produce the correct output, you have to take a drink... All this takes place on the contest stage. It's chaos meets coding. As the night progresses, you are either a really good programmer, really drunk, or a bit of both.

Official announcement on the DEF CON forums

Final Round of DEF CON 101 Speakers!

Final round speakers image

As promised, here's the final additions to the lineup for DEF CON 101. Make yourself familiar, maybe pick out a couple.  Nobody likes to be standing in line for an SRO talk only to get stuck in the hallway, missing all the goodness because of a failure to plan.

Well, there's probably a rule that says someone must like that, and probably mods a subreddit about it like /r/missedyetanothercoolDEFCONtalk. But that someone is weird. Weird and possibly dangerous. Don't be that someone. Read ahead and make some plans.

DEF CON 23 Workshops Schedule is Live!

Workshops image

These are brand new - intensive, deep-dive workshops on topics like Android reverse-engineering, Honeypots and Crypto for Hackers!  They’re free, but you’ll need to register onsite. Space is obviously limited, so if one of these topics really grabs you you’re gonna want to make signing up a priority when you get to the venue. There will be overflow lists, too, in case not everyone shows up. It is Las Vegas, after all. Sometimes you lose someone for a while.

Spread the word - we’d love these workshops to have a great first year.

DEF CON 23 Speakers: Round Four is Live!

Announcing the DEF CON Call for Parties!

Call for parties image

'From Dusk 'til Con' is back with more space, more opportunities and more DEF CON-provided bartenders. If you've got an idea for a party, shindig, hullabaloo, Esperanto-based MUD, you know, whatever, you should share them with us. If your idea is one of the winners, you'll get to throw your party at DEF CON. The main requirements are a well-thought out idea and a quick e-mail trigger finger. You can find the full story on the Call for Parties page. Go there, make a plan, become a party legend.

DEF CON 23 Room Blocks Nearly Full!

Hotel infographic image

Still hoping to stay in the DEF CON hotel block at our group rate? It’s time to get a move on. Our block at LINQ has sold out, and Flamingo and Planet Hollywood are close to capacity. There’s still some rooms at our rate Caesars, but the window is closing fast, and the risk of getting stuck with an overpriced room in the uncharted wastelands of the Strip grows with every passing day. Fortune favors the bold action, friends. Book soon, or brave the outer darkness. 


Internet of things village image

New for DEF CON 23 is the evolution of the last years DEF CON Media server drive duplication into the data duplication village.


DEF CON will provide a core set of drive duplicators as well as content. It will be a first come, first served situation. Bring and label your 6TB SATA blank drives, and put them in the queue for the data you want and 14 hours later it is done.


_ 6TB SATA3 new drive(s) - If you want a full copy of everything you will need three.

_ Any data you want to contribute to be shared, in USB, HDD, or DVD format

You can both contribute data to be duplicated, as well as bring blank drives to get copies and help spread the knowledge.

Those who want to share their own collections or help with duplication are encouraged to bring their own collections and drive dupers. If your collection is smaller we are thinking of getting some USB thumb drive duplicators for smaller batches. We also will have a DVD duper tower, so bring those legacy DVDs.

IoT Village "Call for X"

Internet of things village image

The ISE and the IoT Village announced ‘Call for X’, a call for presentations for an open-format presentation track at DEF CON 23. From the announcement:

“Call For X’ is a play on the mathematical construct of X as an unknown variable,” explains Ted Harrington, one of the lead organizers of IoT Village and the Executive Partner at ISE. “The Call for X is an open-format track for the IoT Village. We want researchers to make suggestions about innovative ways to teach workshops, tutorials, games, or anything else related to the Internet of Things. We are trying to open the platform of learning to dynamic innovation that will help deliver exciting, new and effective ways to reveal solutions for the emerging IoT security problem."

The Call for X CFP is open until June 30, and the information you need to participate is at . Get your ideas together and spread the word.

Round Three of DEF CON 23 Speakers is now Live!

Speakers round 3 image

More approved presentation goodness - round 3 of DEF CON 23’s accepted speakers is now LIVE. Our team of dedicated reviewers has been hard at work finding the best talks in the mountains of entries, and you are now free to read through the abstracts and start formulating your info-hoovering plan for Vegas.

Three rounds of speaker selections down means that DEF CON really is starting to get close.There are a few more updates to come before the roster is complete, but it’s already clear it’s gonna be a heck of a Con, presentation-wise.  Remember to watch this space and we’ll update you as soon as we have new speaker selections.

Another thing to keep in mind is that there’s more going on, speaker-wise, than just the Official DEF CON tracks. The Villages have their own speakers throughout the con - you can find links to all the individual village websites at

DEF CON 23 CTF Quals Write-Ups!

CTF image

The last qualifying event for DEF CON 23’s CTF competition is in the rear view. For those of you who didn’t compete but want an idea of what a high-level CTF competition looks like, we offer links to some quality write-ups. The write-ups not only give you insight into the competition, but the careful reader can also learn something of the mindset that succeeds at this kind of contest. If you’re on the fence, it’s time to read up, level up and get in the arena. CTF glory awaits.

New Speaker's Corner!

Speaker image

Brand new 'Speaker's Corner' post on - 'Hackers and Healthcare: A Call to Arms' by Christian “quaddi” Dameff, MD and Jeff “r3plicant” Tully, MD.

Quaddi and r3plicant are hackers who moonlight as physicians, and the piece makes the case that turning around the rash of healthcare industry data breaches and tech failures is going to require cooperation with the hacker community.

If you'd like some more of these hacker/doctor/futurists dropping science,  you're in luck.

from DEF CON 20 'Hacking Humanity: Human Augmentation and You'

from DEF CON 22 'Hacking 911: Adventures in Disruption, Destruction and Death'

The 2015 DEF CON CTF Qualifications are complete!

CTF image

From the upstanding citizens of the Legitimate Business Syndicate:

"Thanks for being a part of our biggest DEF CON CTF qualifiers yet. We're still very excited at how well the 4407 players, 1472 teams, and over 4000 unique IP addresses performed in our game, and have some preliminary results and other information to share with you."

The contest ended with a three-way tie between PPP, DEFKOR and 9447. As the LBS sorts through the data, they'll post everything at

For those of you who'd like to get a close-up view of the action, you can find a whole bunch of writeup goodness at…/…/tree/master/defcon-qualifier-ctf-2015

If you competed and have a write-up to contribute, that's a great place to put it.

Thanks to all the competitors and to the Legitimate Business Syndicate for making everything happen. Good luck to the groups moving on to the big showdown in Las Vegas, where it shall be on like the proverbial Donkey Kong.

There Are Still Speaking Opportunities at DEF CON 23!

Speaker image

The main CFP is closed, but that doesn't have to mean you can't speak at DEF CON 23.

Several of the Villages are still looking for speakers in their specific subject areas. If your idea is about Crypto/Privacy, IoT, SE or Packet Capture, quick action could still secure you a speaking opportunity before an audience that's passionate about the topic at hand.

Crypto and Privacy village - Deadline June 30

Internet of Things village - Deadline May 26

Social Engineering Village

Packet Capture Village

Let the DEF CON 23 CTF Quals Begin!!

CTF image

The time has come. The final qualification opportunity for CTF at DEF CON 23. Team size - ∞. Registration - open, and available all the way until the contest ends. Battle begins at midnight UTC, May 16 and runs until midnight UTC May 18. If you think you deserve a spot at the Vegas finals, this is your last opportunity to prove it.

For up to date info on the contest you can follow the scoreboard at or keep an eye on @legitbs_ctf and @defcon.

Prepare your team. Reach for glory. Godspeed, one and all.

Reminder: DEF CON 23 Call For Suites and Call for Demo Labs are Open!

Demo lab image

If you've got a project, a gadget or a tool that you'd love to show off to DEF CON attendees, there's still time to sign up for the DEF CON Demo Labs! You bring your wares, and we provide you with a dedicated time and location to show them off. It's a great opportunity to get your project some user testing, cultivate some collaborators or get an idea how your idea rates with the hacker demo. The information you need to sign up is here:

What would you do with a whole penthouse suite at DEF CON? Throw a party the bards will sing about until the end of days? Film a security 'Shark Tank' reality show? Roomba Thunderdome? Come up with a cool concept, event, or party that will be open to all attendees from Thursday to Sunday and if you are selected DEF CON will release to you or your group one of the suites at a cost of $500 per night - so $2,000 for the con. They usually go for $1,500 to $2,000 per night. You can read the whole announcement on the DEF CON 23 site:

DEF CON in the News: FOIA Edition

First ever spot the fed contest image

Our humble party game 'Spot the Fed' is getting a lot of press lately.

Which is cool.

The good folks at MuckRock filed a FOIA Request that asked for, among other things, the FBI's files on DEF CON, and at the end of April they got a response in which STF is mentioned specifically a few times.

Which is also cool, but there's a little more to the story that DEF CON fans might be interested to hear.

First: Spot the Fed for the uninitiated.
Spot the Fed is a con amusement enjoyed by hackers and Fed/Gov/LE attendees alike, and it works thusly: Con-goers notice a suspicious 'outdoor kid' lurking about, and they alert a Goon (preferably Priest). With the spotee's permission, Priest or one of his minions asks a battery of questions designed to discover their mode of employment. If MIB status is uncovered in the course of questioning, the spotter and the Fed get T-shirts. Both spotter and spotted are then free to resume their conference unmolested. So it's sort of a catch-and-release program, if you will. We pride ourselves in both our ability to spot Feds, and our ability to return them in the condition received.

Now, a little backstory.

For reference, here's a shakycam recording of a round of Spot the Fed from DEF CON 14, featuring the incisive interrogatory style of Priest.

The picture attached to this post is from DEF CON 2 and features the very first Fed ever Spotted wearing the very first 'I Am the Fed' shirt we ever gave out. Memories.

Astute readers of the FOIA docs

will notice that there was another FOIA request for DEF CON still being processed at the time that MuckRock's request was going through. That request came from badass EFF lawyer and frequent DEF CON speaker Marcia Hofmann, and it was filed in response to a Federal Grand Jury investigation that you might recognize from the DEF CON documentary.

The docs actually help solve the nagging mystery DT's talking about in that video.

"I had always assumed the grand jury investigation was related to a National Security investigation, but now that the FBI FOIA is out we know. FEDs don't all attend because of the talks, sometimes they have real work."
-Dark Tangent

The docs are liberally redacted, but they do illustrate the varying levels of interest lavished upon our little party by one of the TLAs in attendance. The docs MuckRock released include reports from DEF CONs 3, 8 and 12.

Despite the hostility people insist on reading into the FBI comments, spotted Feds almost universally take the stage with good humor and answer our questions with patience and more candor than their job descriptions require.

If you want to get in on the FOIA action and see some FBI files of your own, we recommend watching this talk from the aforementioned Marcia Hofmann from DEF CON 18.

Anything else awesome that involves IoT devices!

New Speaker's Corner: CFP Process FAQ!

Speaker image

This is the home stretch for getting your talk submitted for DEF CON 23. The submission deadline is May 10. If you still have unanswered questions about the process of submission or selection, Leah has created a pretty exhaustive and very useful FAQ on Speaker's Corner!

The DEF CON 23 Call for Contests,
Events, & Villages is Open!

Call for Contests image

We know you have ideas. We know you’ve walked the floor at DEF CON and thought, “I know what kind of contest or event this place needs. One day I’m gonna get MY idea for Roomba Thunderdome to DEF CON and rule this place."

That one day is today (but not if your idea is Roomba Thunderdome - that’s mine). It’s time to take your great idea for a DEF CON contest or event and submit it to us. If it’s good enough, and you get it submitted by May 30, you may get to see your idea become a glittering Las Vegas reality.

The information you need to manifest your brilliance has a Forum thread. Go there and make us proud.

The DEF CON 23 Vendor Application is Open!

vendor application image

The DEF CON 23 Call for Vendors is now open, so if you have a product or merchandise you want to put in front of thousands of hackers you should check out . It’s all there – all the info, the vendor area layout and even a surprisingly thorough FAQ. As always, we run out of vendor space pretty fast, so it’s a good idea to get yourself registered as soon as you can. The early bird catches the worm, and the late bird has pallets stacked with regret.

Call for Papers Reminder...

May 10 will be upon us in less than a fortnight - is your submission prepared? Tarry no longer, friends. Fortune favors the bold.

Submit to the DEF CON 23 CFP before glory slips from your grasp.

DEF CON Villages Happening Now at Tribeca Film Festival!

Hardware hacking village image

Reminder: The DEF CON Villages are up and rocking at the ‪#‎tribecafilmest‬ in NYC! Four Villages (Crypto/Privacy, Hardware Hacking, Tamper Evident and Lockpicking) full of hands-on activities and clever humans spreading hackish knowledge.

The Villages are live today through Saturday, and our founder Dark Tangent will be speaking Saturday at noon. LosT, our resident mad crypto scientist and creator of the Mystery Challenge will also be making an appearance.

It's all going down at Spring Studios at 50 Varick St. You can find out more at…/tribeca-film-festival-2015-def-con .

Flashback Friday: Airplane Security

screencaps of talks about airline security

In light of the story about Chris Roberts of One World Labs being pulled off a plane by the FBI after talking on air about some of the risks inherent in in-flight networking, for #defconflashbackfriday we give you two talks on the subject of security in the air.

The first is from DEF CON 22. The presenters are Dr. Philip Polstra and Captain Polly and it's entitled "Cyberhijacking Airplanes: Truth or Fiction?"

From way back at DEF CON 20, we also offer "Hacker + Planes = No Good Can Come of This" by Renderman.

The security research community does indispensible work in the public interest. Making that work inconvenient or impossible serves only the bad guys.

Noir Science, Part Two: Neo-Noir

While the classic Film Noir period happened in the 40s and 50s, the style and preoccupations of Noir are alive and well. Sometimes referred to as Neo-Noir - here’s five notable takes on the genre that will get you up to speed:

Blade Runner: The undisputed champion of sci-fi flavored Film Noir. Hard-boiled private investigator, rain-slicked streets drowning in neon and depravity, a secret so dark we keep it from ourselves. Add to this the insanely detailed and haunting visual design - still maybe the most beautiful dystopia ever committed to celluloid - and you have a permanent chart-topper.

Blood Simple: The Coen Brothers' debut film about small-town jealousy and betrayal is both a love letter to Noir and a darkly comic blast of adrenaline that still stands up over 30 years later. The plot is an ever-tightening noose of bad faith and personal corruption.

The Killer: John Woo. Chow Yun-fat. Doves, the Hong Kong skyline and So.Many. Bullets. A grimly beautiful tale of underworld honor and devotion with operatically insane actions sequences that are still being copied around the world.

Brick: Underappreciated high-school noir starring Joseph Gordon-Levitt as the dogged investigator determined to find the truth, damn the consequences. The setting and the distinctive slang make it unique, the performances make it a first-ballot hall-of-famer.

The Yellow Sea: 2010 film by South Korea’s Na Hong-jin about an ethnic Korean (Joseonjok) taxi driver in Yanji, China. His twin obsessions with gambling and his estranged wife lead him into a murder plot that’s way out of his depth. You might watch some of this through your fingers, but it’s compelling cinema and steeped in Noir style.


Honorable mentions: To Live and Die in L.A, Shallow Grave, Oldboy, The Last Seduction.

Announcing yet another cool way you can participate in DEF CON: the DEF CON Demo Lab!

New for DEF CON 23 we are adding an place for you to show off your tools, projects, and tech to attendees - much like a poster board session but with computers.

The DEF CON Demo Lab is a dedicated area for hackers to show off what they have been working on, to answer questions, and even convert attendees into trying of giving feedback on their projects.

Presenters will be given a dedicated time and location to present a tool or project of their creation; show what it does, how it works, and why we need it in our arsenal.

DEF CON 23 Call for Workshops!

call for workshops image

On the 3rd floor of Ballys South tower, The Jubilee Tower, lay seven rooms [1], each one 1,400 sq feet. That's enough space for about 55 people in classroom format. What to do with all that space away from the main action of the convention? I've wanted to try workshops and trainings for years but we have never had the room once we filled up the Rio. Now we finally have some space at the new hotels so I am calling on the community to tell us what we should do with the rooms.

Check out the Call for Workshops for full details!

DEF CON Villages make an appearance at the Tribeca Film Festival!

tribeca film festival image

For the first time ever, DEF CON is teaming up with the Tribeca Film Festival to bring a few of its famous Villages to New York. The Villages – interactive spaces stocked with gear, projects and brilliant humans – immerse the visitor in particular nodes of hacker culture. Hands-on activities, eye-opening presentations and open-ended experimentation combine to bring out the hacker in everyone.

Join us April 23 - April 25th, 2015 in Studio X of Spring Studios and you will:

• Learn to pick a lock in the Lock Picking Village.

• Make your devices and identity more secure by seeing how the bad guys operate in the Privacy/Crypto Village.

• Study the noble art of voiding all your warranties in the Hardware Hacking Village.

• Get schooled in the hacker's most important skill in the Social Engineering Village.

• Discover what it takes to open that weird security envelope without leaving a trace in the Tamper-Evident Village.

New DEF CON 23 Call for Suites!

Call for Suites image

On the top floor of Ballys are four penthouse suites, and we are calling for people or groups who are interested in renting them and throwing something cool for the hacking community. Here is the deal:

Come up with a cool concept, event, or party that will be open to all attendees from Thursday to Sunday and if you are selected DEF CON will release to you or your group one of the suites at a cost of $500 per night - so $2,000 for the con. They usually go for $1,500 to $2,000 per night. You can read the whole announcement at:

Today’s list: 5 Must-See Classics of Golden Age Film Noir

To get you in the mood for DEF CON’s Noir theme, we offer some Film Noir knowledge and recommendations.

Noir is a slippery category, but it’s generally taken to mean films with a cynical worldview, moody, stylized cinematography and stories that turn on darker human impulses: lust, greed, vengeance.  They are stories of the desperate and the doomed, the outsiders who will never really belong to polite society.


The golden age of film noir is the 1940s and 50s, but the genre left its mark all over popular culture and great noir (or neo-noir, if you’re not into the whole brevity thing) is still being made today.

Double Indemnity: Arguably the film that kicked off the genre. All the elements are present. The lighting is dramatic, the dialog is sharp and the plot turns on murder for easy money. Directed by the great Billy Wilder and written by detective fiction immortal Raymond Chandler. Double Indemnity is the heavyweight champ of golden age noir, with 7 Oscar Nominations.

Kiss Me Deadly: Adapted from the Mickey Spillane novel of the same name. Starts with a disreputable private eye picking up a terrified hitchhiker escaping from a mental hospital wearing only a trench coat, and then things get weird. A Cold War parable with a breakneck plot, a mysterious box and as pitch-black an opinion of the human condition as you could put on screen in 1955.

Out Of The Past: To create the mood of a good noir, you need actors with moodsetting skills - lurking, looming, smoking with intent. No one has ever been better at doing those things than Robert Mitchum. Pay close attention to his looming work in this film. 10/10 would cross the street to avoid. Bonus: You can check out Mitchum being extra foreboding in 'Night of the Hunter'.

D.O.A: Some of the plot tricks in this movie might seem familiar, but only because directors borrow from it all the time. D.O.A. was pretty avant-garde in its time.

Our protagonist is dying - soon. He uses the remainder of his rapidly expiring time to find out who murdered him and see justice done. Lots of newer movies use the forced clock, the backwards storytelling, the inside-out murder mystery but very few of them do it any better.

Touch of Evil: The opening shot - a long, unbroken meander through the scene of our intrigue - is a clinic on mood-setting. Questionable makeup choices aside, this is the platonic ideal of what a dark melodrama should look like.


Honorable mentions: The Killers. The Asphalt Jungle. The Big Sleep.

black badge image

New! Black Badge Hall of Fame!

The Black Badge is highest honor DEF CON can bestow. You have to do something awesome to win one, and if you manage that you get in to DEF CON free for the duration of your natural life. It is, in a word, ballerific. It also maxes out your charisma when worn with an ironic t-shirt.

We’re compiling a history of the winners, and we’ve put up a Black Badge Hall of Fame page to get that process started.


The thing is, we weren’t always so good at keeping records. Because we are a giant Vegas hacker party. It’s pretty likely we’ve left off some deserving names or missed an event or two that were eligible for a Black Badge. If you know something that got overlooked, or think we got something mixed up, please let us know. Drop us a line at and we’ll look into it and fix what needs fixin’.

Link Roundup: DEF CON 23

More stuff returning for DEF CON 23!

SoHopelessly Broken - Last year's popular Small and Home Office Router hacking contest is back, with a twist!

Hair farmers, rejoice! The DEF CON beard and moustache contest is back as well. Your commitment to medieval grooming habits could finally pay off.

And from the DEF CON Forums:

The 'Be The Match Registry Drive' is going to be back for DEF CON 23. This gives you another chance to be a straight-up superhero by getting yourself on the list of potential marrow donors.

You need to be between the ages of 18 and 60, meet the health guidelines and be willing to donate to ANY patient in need. At the recruitment drive, you will fill out a consent form with contact information and a short medical evaluation. You will receive more information about what it means to be a donor and then you will swab the inside of your cheeks. Your tissue type will be listed in the Be The Match Registry until your 61st Birthday. If you are a match for someone in need, then you will be contacted for donation.

New DEF CON Code of Conduct is Live!

DEF CON’s official Code of Conduct is now live on the Policy Page. If you’re planning to attend DEF CON, please take a minute to look it over. The rules haven’t changed, but now they’re in a handy written form for easy reference in moments of quiet reflection or in your hectic, on-the-go lifestyle.

You’ll be expected to hold yourself to the terms of the CoC at DEF CON, but you can take them with you anywhere. Feel free to practice the precepts contained in the DEF CON CoC in the non-DC situations of your choice, including but not limited to board meetings and LARP events.

We appreciate you taking the time to familiarize yourselves with the code, and we leave you with a quote that we believe gets at the heart of what we’re trying to create here, from the collected wisdom of Theodore Logan and Bill S. Preston, Esquire.

‘Be excellent to each other.’

New FTC Contest, Robocalls: Humanity Strikes Back

Rachel from cardholder services is back and there's a price on her head.

Fresh off the popular 'Zapping Rachel' contest at DC22, the FTC is returning to DEF CON this summer with a brand new contest and a big wad of prize money. Called 'Robocalls: Humanity Strikes Back', it challenges you to create a tool that allows mobile and land-line users to identify and block robocalls or deflect them to a honeypot for great justice.

The qualifiying round is open now and closes June 15. Qualifiers compete at DEF CON 23 for cash prizes, including $25,000 for the winner. You can find all the rules and regs on the contest website.

Contests, Events, & Villages, Oh My!

We're a little past the halfway point between cons, but DEF CON 23 is already taking shape nicely! Cool stuff with intention to return for DC 23 includes:

Black Bag
Crash and Compile
Capture the Flag
Darknet Project
Scavenger Hunt
Short Story Contest

Ham Radio Exam

Villages: Crypto/Privacy Village
Hardware Hacking Village
Lockpick Village
Packet Hacking Village
Tamper-Evident Village
Wireless Village
Social Engineering Village

And there's lots more to come.

In the coming days, we'll be highlighting different individual contests, events and villages in this space, so keep an eye out. If your favorite thing isn't yet on the confirmed list, you can keep tabs in the Contests & Section of the DEF CON forums. It's never too early to start planning how you're gonna get involved this year.

Policy image

New Policy Page!

Today we’re launching a brand new policy page at, and we’d love for you to take a look at it, and only partly because of the emotional validation it will provide for our lawyers. There’s also a lot of useful information on the page for everyone who plans to visit our conference or our website. As of today, there are three documents up there:

Privacy Policy
We make a real effort to protect whatever pieces of your identity pass into our hands, and we want you to have an understanding of what we can and can’t do to keep that data secure.


Transparency Report
It’s reasonable to wonder if sites you visit frequently have been served with a court order demanding logs and information. The transparency report is how you’ll know if it happens to DEF CON.

Black Badge Policy
Wonder if that Black Badge on eBay will render you ‘uber’ at the next DEF CON? There are rules, and we wrote them down for you.

As other policies are finalized, we’ll update the policy page. If you need another reason to check it out, consider this: every time someone reads a privacy policy all the way through, a lawyer gets their wings. Or a lawyer does 1d4 of smoke damage. It’s one of those.

Server Security Upgrades - DT's Blog

After moving all of the DEF CON hardware (because the building was scheduled to be demolished – go figure), we started a pretty rigorous set of security upgrades.

HPKP support on the webservers? Check. DNSSEC support all around? Check.

In an effort to keep you informed about what we're up to, security-wise and to maybe inspire everyone to get up to date, DT has started a blog on the DEF CON forums about the upgrade process.

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.

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.

We've got two more versions of the DC22 talks available for your torrenting pleasure. We've got slide only video, with the audio and slides uninterrupted by speaker face. We've also got talking head video, which is audio and speaker face uninterrupted by slides.

If either one of those is your preferred flavor, then your moment has arrived. As always, we ask only that you enjoy them and seed them so others can enjoy them as well.

It's us against the derp, people. Let's spread the knowledge.

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:

Link Roundup: Onymous Edition

Last week 'Operation Onymous' - a Law Enforcement sweep of Tor hidden services websites - netted about 400 takedowns and 17 arrests.

The Tor blog has a post summarizing what happened, offering suggestions and soliciting feedback. The operator of seized hidden service site Doxbin has released his logs in hopes of helping find how the network was compromised.

For anyone looking for a discussion of the Tor network, what it can and cannot do and what users must do to maximize its effectiveness, we offer a talk from the Tor Project's Runa Sandvik from DEF CON 21.

Link Roundup: Assault on Mobile Privacy

We've mentioned it before, but the news about government spying sort of drowns it out: the commercial entities tracking your digital footprints are just as determined to capture all of your data and use it against you.

This week's big corporate data collection story was about Verizon and the 'unkillable' 'perma-cookies' they've been injecting into their customer's web traffic. It's certainly more the rule than an isolated example of service providers getting all up in your KoolAid, but it's generated interest because Verizon is huge and they are going out of their way to circumvent privacy measures built into your mobile devices.

This link roundup is about the Verizon story, but it's also a general reminder of the hard work that many, many digital middlemen put into unraveling your privacy sweater for power and profit. It's also a reminder that we have to be loud about these intrusions if we want them to stop. Companies like Verizon are not going to voluntarily give up all that sweet data unless they know they're going to lose subscribers.

We close the roundup with a link to a turbo talk from DC 19 about one man's work toward unveiling the methods of some major corporate browser history snoops.,news-19848.html

Golden Key

Link Roundup: Crypto Wars Reloaded

In September, Apple and Google both announced that they were going to ship their new devices with encryption turned on by default.  

This has caused some concern in the Law Enforcement community. James Comey, current Director of the FBI, went on 60 Minutes to urge manufacturers to reconsider. He believes that if the good guys don't have a 'golden key' to everyone's mobile device, the bad guys can 'go dark' and gain an advantage will lead to terror, child abduction and ‘threatens to take us all to a very, very dark place’.

There are a lot of problems with this logic. For example:

Evildoers always have the option of ‘going dark’, regardless of how much privacy we give up.

The 'golden key' isn't the only way for LE to get the data they want.


Most importantly, it's not possible to create a back door that can be entered only by the pure of heart. If the righteous can squeeze in today, the sketchy will, inevitably, squeeze in tomorrow. Later today, most likely.

More Torrents for You!

Another couple of torrents for your edification and delectation.

First, the X-Hour Film Contest:

This was a first year contest that asked entrants to script, shoot, edit and submit a short film in 48 hours, in the middle of DEF CON. Seven teams entered, four teams submitted a final film and the winner was announced by celeb guest judge Brian Knappenberger (director, 'We are Legion' and 'The Internet's Own Boy'). They're also available to watch on the DEF CON YouTube channel. CON 22 x-hour film contest.torrent

DEF CON 21 Music is up!

Tired of listening to your mp3 collection? Looking for a way to spice up that ho-hum hard drive? When's the last time you and your music stash really... connected?

Take care of your ears. Hot DJ sets have been shown in clinical trials to help treat the symptoms of boredom, malaise and sickofmycollectionitis. Side effects may include stupid grin, periodic head nodding and uncontrolled shaking in the booty region. If symptoms persist for more than four hours you should probably drink some water.

Ask your doctor if DEF CON 21 Music Torrent is right for you.

As we get them in, we’ll put them on.

That’s what we are doing for you, for loving the CTF tournament. What you can do for us is seed, seed, seed and spread the word.

Read All About It!

Every year, we collect and share a sampling of the published reports from the press that covered DEF CON. It's interesting to see what gets the most interest, and it's gratifying to see that every year there are less stories about how scary hackers are and more stories about the incredible things hackers create and what we can learn from investigating the technology that surrounds us.

Transportation security, digital privacy, and the unexpected musings of eccentric AV software titans seemed to top the list in 2014. You can peruse the whole thing at your leisure on our press archive page.

DEF CON 22 Archive is Now Live!

Good news, everyone! The archive page for DEF CON 22 has opened for business. It feels like DC was only a couple of weeks ago, but you can already see the slides and extra materials from all the main-track talks.  We’ll eventually be adding audio and video as well, so keep an eye on this space. In the meantime, bum rush these Power Points to your heart’s content.

For Early Release - The Internet of Fails

Early Release! More video from DEF CON 22! This time it's a presentation from Zach Lanier and Mark Stanislav about the many ways the Internet of Things isn't ready for prime time, security-wise, and some insight into the work being done to make it safe to connect your various 'Things' to the IoT.

Contest Results Page — Now Live!

We had a lot of incredible contests at DEF CON 22. So many contests that they could have seceded and formed the People’s Republic of Contestia. So many, in fact, that the results are still coming in over a week later. To keep you informed, we’ve created a Contest Results Page on Check out who won, find links to the contest websites for further information.

If you don’t see your favorite contest, let us know @defcon or contact the contest organizer and ask them to submit their results.


Keep it going all year!

So you've been home from DEF CON for a week now - probably settled back into your normal routine. In the back of your mind, though, there's probably a little voice that wishes you could have DEF CON-style hacker camaraderie and learning opportunities all year long.

The good news is, you can. You can join a DC Group in your area. If there isn't a DC Group in your area, you can start one. The instructions for starting a group are at the link below, as well as a listing of the hundreds of groups that already exist around the world.

And when you get involved, be sure to keep in touch with us on social media. Let us know when you're meeting and we'll share it. Tape your presentations and we'll share those, too. Let's make this the fastest trip from one DEF CON to the next by keeping the ball rolling all year.

DEF CONversation with LosT, DEF CON's Mindbender-in-chief

One of DEF CON's secret weapons is LosT, our resident Puzzle Master and Lord of the Badge. You can see his work all over DEF CON, from the insanely hackable badges to the secret codes and messages hidden all over the program and the venue.

Dark Tangent interviews him here about all of his various DEF CON activities, his process and even gets a few hints dropped for next year's puzzles.

News from the Front!

The hackening is in full swing at DEF CON 22. The Rio is abuzz with all manner of high-octane geekery.

Quick Update Roundup!

DEF CON is in full swing - so there’s a million things going on. Here’s a few recent news items to tide you over while we get the party set up.

If you’re one of those people that enjoys being entertained by entertaining entertainers, you’re going to want to check out our newly minted ‘Entertainment’ page. So much music - it’s like Coachella for people who people smart enough to test out of Coachella.

For lawyers, judges and law students, there’s a Lawyer Meetup this year. DEF CON General Counsel and Chief Legal Raconteur Jeff McNamara invites all with a connection to the practice of law for a relaxed low-key meet up followed by a spirited trip to the Voodoo Lounge.

Don’t forget to stop by Track 3 at 9pm on Friday and Saturday for Movie Night with Dark Tangent. Friday we’re showing ‘The Internet’s Own Boy’ - a moving bio of internet hero Aaron Swartz. Director Brian Knappenberger and Aaron’s brother Noah will be in attendance for Q&A.  Saturday, we’re showing ‘The Signal’. Directed by Will Eubank (who will also be in attendance), ‘The Signal’ is a mind-bending new scifi film that starts with some hackers on the road to DEF CON.

A few pro tips: stay hydrated, remember to eat and sleep. Keep the program handy - it’s like the Galactic Encyclopedia of DEF CON. Bring extra socks. Make new friends. Hack 100% of the things.

Soma FM Logo

SomaFM at DEF CON 22!

One week, people. All that stands between all of us and DEF CON is a few measly days. To help get you amped up, we offer the SomaFM preview stream. Like last year, SomaFM will be manning the chill room and providing luscious, rejuvenating audio delights whenever you're looking for a recharge or a welcoming nook amidst the chaos.

Fire up the stream and close your eyes. It's like you're already at DEF CON. One week, people!

For the Kids: Rootz Asylum at DEF CON 22

Rootz Asylum (formerly DEF CON Kids) has a full schedule of goodness planned for your padawan hackers. Learning, competition, fellowship with other hackish youth. It's pretty great. Back-to-school will definitely be cooler for the kids who spent their summer vacation winning DEF CON.

Movie Night With Dark Tangent: ‘The Signal’

The sci-fi mind bender ‘The Signal’ centers around hackers on a road trip to DEF CON, so we can be forgiven for being a little biased in its favor. But from that promising starting place, the escalating weirdness and suspense take the movie everywhere but where you might expect. We don’t want to spoil anything - you’re gonna thank us if you go in with a clean slate. We’re proud to have ‘The Signal’ for Saturday’s ‘Movie Night with the Dark Tangent’, and we’re prouder still to have director Will Eubank on hand for Q&A after the screening. The last reel will definitely make you want to talk to Mister Eubank. Make it a point to be there!
Saturday the 9th at 21:00, Track 3

Hard drive dupe image


For even faster leeching pleasure of the conference media server we have invested in hard drive duplication towers, and next year DT plans to launch the Data Duplication Village.

Too busy to pick and choose what you want from the server and want it all?? This year we have three sets of 4TB drives that contain the same data as the media server, just split up and color coded. If you want to duplicate a particular drive you need to show up at the INFO BOOTH with your drives at the start of each day. First come First server. It will take about 8 hours to dupe a 4TB drive so a set will start in the morning and a set in the evening, to finish overnight.

There should be six 1:11 duplication towers (If they show up in time), with two for each drive color. That means we can dupe 66 drives at a time. Once enough people show up to fill a station the duplication process starts.

As of this writing it is sorted like this:

BLUE Drive = Conference Archives 1 of 2, including DEF CON
GREEN Drive = Conference Archives 2 of 2
ORANGE Drive = Podcasts, Cryptome, 1.5T of the Hak5 archives, FOSS Operating Systems, all other content

There will be an updated list at the infobooth.

Want in on it? Go buy some 4TB SATA II 7200 RPM drives (internal drives, not usb). Buy three if you want to try for the complete collection this year. I'd do it in advance, I think the local Frys will sell out! Duping should start Thursday!

The Orb

DEF CON 22 Music Announcement: THE ORB

You better have just done that spit-take. That's right. Electronica/Trip-Hop/IDM/dub music classics and pioneers: The Orb. They're here. They're kicking. And on the 3rd day of DEF CON (Saturday night/Sunday morning 00:00-01:00) their divine presence shall bless the glorious attendees who... attend their glorious and divine performance. Those who do not attend will be forsaken and cast into the dystopian landscape known as "the rest of Las Vegas." And so this event shall henceforth be written into the Dark Tangent's Book of DEF CON, Volume 22 - also referred to by some as "the conference program." So say we all.

DJ Spooky: That Subliminal Kid a.k.a. Paul D. Miller

DEF CON 22 Music Announcement: DJ Spooky (That Subliminal Kid) a.k.a. Paul D. Miller

A major announcement right here. We're bringing you the legendary DJ Spooky (That Subliminal Kid), a.k.a. Paul D. Miller. His CV runs deeper than the Mariana trench and is more Renaissance than the Teenage Mutant Ninja Turtles combined. Perhaps originally and best known for his artisinal music crafting (collaborating on projects with Meat Beat Manifest, Slayer, Chuck D.) and turntablism , he's become a university music professor (EGS, Switzerland), author (too much stuff to list), and an executive director of Origin Magazine. He's had his works featured in major museums like the Warhol, The Whitney, the Museum of Contemporary Art (Chicago), blahblahblahblah the pseudo-anonymous writer of this announcement could go ad infinitum. The point is, he's attained legendary-levels of awesome, and is coming to DEF CON to drop some hip-hop (perhaps with orchestral accompaniament) on Thursday Night in Track 1 (22:00-23:00)!

Elite Force image
MC Frontalot image

DEF CON 22 Music Announcement: Elite Force & MC Frontalot!

A favorite from DEF CON XX (he dropped the killer set after The Crystal Method), we're bringing the near-mythical adrenaline-inducing Elite Force back for another sonic pummeling. Many of you may also recognize one of his prior projects, Lunatic Calm, which had music featured on films like The Matrix, Mortal Kombat: Annhilation, Drive, and tooons of others. We're extraordinarily excited to have Elite Force back, and we'll all need to be sure to keep our collective cholesterol levels in check to ensure we can survive his performance. Catch him Saturday night in track 1 (23:00-00:00)!

Another throwback to DEF CON XX, we're bringing back one of the grandmasters of Nerdcore hip-hop, MC FRONTALOT. His prolific lyrical stylings have been proverbially known to knock socks off, so shoes (as always) are encouraged (we'll let sandals slide too). He's also the star of the acclaimed documentary Nerdcore Rising. Catch him Friday night in Track 1 (23:00-00:00), alongside other hard-hitters and partners in nerdcore-crime Dual Core and ytcracker!

Check 'em out at the Friday festivities in track 1. (set time: 00:00, Saturday AM)!

Also be sure to check out their totally rad and typically incredibly neon music videos:

Zebbler image

DEFCON 22 Music Announcement: Zebbler Encanti Experience

Do you remember the giant projection-mapped DEF CON exploded face? Or maybe the dragon installation? Or how about the DEF CON sign installation in the chillout lounge last year? These are the epic works of Zebbler's design team, who have also developed installations for the likes of Shpongle, EOTO, and a number of other class acts. But Zebbler doesn't just excel at design. He also excels, along with his comrade Encanti at music. Together, they form an incredible audiovisual duo that goes by Zebbler Encanti Experience, and they will be purveying this experience to you at DEF CON 22! Take delight in their glorious bassy weirdness at DEF CON's official Saturday evening event in track 1 (set time: 01:00, Sunday) !

Most of their music is free/pay-what-you-can too! Check it out:

DEF CON’s First Google Hangout!

We’re trying something new. Friday, June 27th at 11am Pacific Time, we’re hosting our first Google Hangout on Air. The guest is Jennifer Granick, DEF CON CFP Review Board member, preeminent hacker defense lawyer and Director of Civil Liberties for the Center for Internet and Society at Stanford Law School. The subject is her recent article for Wired regarding the verdict in United States v. Davis and what it could mean for the future of mass surveillance.

If you’ve got good questions about the intersection of law and ‘metadata’ collection, either leave them here in the comments or ask them live at the Hangout tomorrow.

DEF CON 22 CFP Review Board Revealed!

‘This talk is amazing!’ You say this to yourself (inside voices) while watching someone awesome say and demonstrate awesome things. ‘How does DEF CON consistently pick so many great talks? They must have a team of borderline superheroes slogging through hundreds and hundreds of proposals for months! Who could those paragons of determination and insight BE, exactly? How could I learn their handles and perhaps show my appreciation by buying them many beers?’

Here’s an answer key to these questions you’re asking yourself:

1.)This talk probably is amazing. Not really a question.
2.)Lots of caffeine and eyestrain. Also dedication and love.

4.)They are known as the DEF CON CFP Review Board.

Last round of DEF CON 22 Talks are Live!

This is it. The speaker list for DEF CON 22 is now locked and complete. This means two things: DEF CON is really almost here, and we are now hard at work creating the Tracks and the Schedule (watch this space, buckaroos). We're very proud of the lineup we've assembled, and we think you will find a lot of good stuff to choose from. Whether you're coming to Vegas or not, we'd love it if you'd take some time to check out the speaker list and give us some feedback about what talks have you the most excited.

55 days, people. Get psyched!

DEF CON Secret Media Server Project Revealed!


The previously sooper seekret server project has leaked out on the twitter and the face book. No use hiding behind our press secretary any longer, It's better to just admit it and let everyone make up their own minds.

WHAT LEAKED? The Dark Tangent is collecting as much open source security conference footage, training materials, podcasts, white papers, videos, and anything else haxors may be interested in. He plans to make it all available at DEF CON 22 in August and let anyone download it, or even direct HD copy it.


WHAT NOW? A huge burden has been lifted off of DT and he no longer has to live two lives. He can now focus on getting as much content as possible from the community.

That's where you come in.

Send links to content you think everyone should have access to that is related to the hacking and infosec scene somehow. It can be an rss podcast, a .torrent of academic journals, and ftp link to text files, a web site to mirror full of source code, an svn operating system repository, a YouTube channel, whatever!

Send your links in an email to, or tweet them to @thedarktangent and he will start the leeching.

At DEF CON 22 you will be able to get to the gigs in a couple different ways. The con Wi-Fi network (at 802.11g speeds), through wired switches on 1 gig links in different areas, or by bringing your own 4TB SATAII or III hard drive(s).

We will have HD duplicators running all con copying drives for people who just want to drop off a drive and pick it up later.

Please help out with links, and we'll see you at con!

Crash and Compile Logo

Registration Now Open for Crash and Compile

Do you think you can code? Do think you can code while drinking? We're not talking about coding in the warm safe confines of your cubicle. No, this is programming for sport. It's live competition, against the clock, and the other teams. And we don't make it easy. Have the smarts to solve our programming challenges? Good. We want you to show us that programming is not only about laying down some sweet sweet code, it's about the style in which you do so. Sound fun? We think it is.

Crash And Compile is a ACM-style programming contest crossed with a drinking game, where teams of two people try to solve as many programming problems as they can. As teams compile and run their programs, each time their code fails to compile, produces the incorrect output, or seg-faults, the team must drink. Meanwhile, our lovely Team Distraction will be doing what they can to make the job of programming while intoxicated all the more difficult and/or enjoyable.

Registration is now open. Sign up over at

Big 'Ol Batch of Talks!

It’s getting pretty real, people. The speaker selection process is almost complete, the party and event planning is in full swing - DEF CON 22 is just a little over two months away!

To celebrate, another round of speaker announcements. Twenty-five more abstracts to help you create your DEF CON battle plan. We anticipate one more round of announcements before the roster is locked, but by now you should have a pretty good idea how much good stuff we have on tap.

DARPA Cyber Grand Challenge Logo

DARPA announces its 2-year Cyber Grand Challenge, Final Tournament at DEF CON 24

The Cyber Grand Challenge asks some simple questions - can you create a fully-automated system to detect, thwart and mitigate network attacks? Can you build one so effective that it can win an all-computer tournament without human intervention? Would you like 2 million dollars?

If you have a great proposal but lack the funds for a 2-year competition, you can pitch DARPA for funding - they’re already backing seven of the registered teams. Teams that survive the quals in June 2015 are eligible to compete in the final tournament at DEF CON in 2016. Grand prize is $2 million dollars.

Competitors will need a dizzying array of skills and an encyclopedic understanding of every form of network kung-fu. They will also need a pretty serious amount of free time, but the winner gets a nice check and an answer to the question of what to put first on a resumé.

We believe that such a team must exist in the DEF CON family. If you think you’re up to the challenge, more information awaits you at the DARPA CGC page.

DEF CON 22 CTF Quals Roundup!

The DEF CON 22 CTF Qualifiers are in the books. Challenges were faced, and bested. Points were accumulated. Bedtimes were missed. It’s all over but the paperwork.

So here’s a roundup of writeup links. IF you participated, read and see how other people approached the same problems. If you didn’t, read and get an idea of how the CTF process works and consider signing up next time. You lose 100% of the CTFs you don’t enter.

If you enter, you could still lose 100%. That’s just math. But you’ll have a story. An awesome, glorious, highly technical story to share with the tiny slice of humanity who can understand this sort of thing.

There’s also a bonus link to a GitHub collection that looks like it might end up pretty comprehensive.

Vote for People's Choice in the DEF CON 22 Artwork Contest!

The DEF CON 22 art contest has closed, and it’s time to start picking the winners. In the ‘People’s Choice’ category, that means it’s time for YOU to cast a vote. Check out the Artwork Contest Entries Gallery on Facebook and cast a ‘Like’ for your favorite.

The winner gets free admission to DC22, $25 credit at the Swag Booth and inky immortality in the DC22 printed program, so it’s kind of a big deal. The theme was ‘Behind the Curtain’, and the winning work should in some way capture the sense of the hidden world behind the world that is seen. Cast your votes wisely.

And as always, we thank everyone who participated in this year’s contest. If you didn’t submit and you’re feeling a little jelly, we offer the wise words of Socrates, who said to his students, “He is not wise who playa-hates; the truly wise participate. This mimosa is terrible.”

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.

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.

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.

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™

In Case You Didn't Know...

This may be old news to some of you, but we've noticed a lot of questions in the comments from the last few Facebook posts about where past DEF CON Content resides. We have several outlets: is a directory browsable repository for all of our past content. for all of our torrent files. These are the huge collections for all-at-once downloading. is a portal to our archive pages by year.

These include audio, video, CTF files, artwork and a ton more! So if you didn't know, now you do. Pick your poison and enjoy!
