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

For your weekend, another #defconflashbackfriday early release talk from DEF CON 24 - this time Marc Newlin on the hijacking of wireless mice for nefarious purposes. He calls it 'MouseJack'.

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 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 24 writeups image

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.

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.

Workshops On-site Registration Instructions!

DEF CON 24 workshops registration image

Workshops are free, first come, first served, and seats will fill up fast!

There ain't no show and tell like a hacker show and tell.

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.

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 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.

DEF CON 24 Wireless Village image

Wireless Village CFP is open - closes June 30!

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

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.

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.
