DEF CON Announcements!

DEFCON is the world's largest annual hacker convention, held every year in Las Vegas, Nevada. The first DEFCON took place in June 1993. DEF CON is renowned for the "arcane arts" of drinking, socializing, debugging, and crowd control. DEFCON is what you ma

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

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


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

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

Fri, 14 Oct 2016 09:38:25 -0700


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!

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


From their Facebook page:

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

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

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

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

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

Medical Device Security, and the Possibilities

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

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

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

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

DC813 is holding a CTF!

Fri, 30 Sep 2016 14:32:28 -0700


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

Wed, 14 Sep 2016 13:44:29 -0700


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.

Please enjoy and then pass it on.

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

Thu, 08 Sep 2016 14:56:42 -0700


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 Press!

Thu, 01 Sep 2016 16:27:55 -0700

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

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


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

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

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

As always, watch, learn and share widely.

DEF CON 24 Contest Results are Live!

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


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

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

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

DEF CON 25 Will Be At Caesar's Palace!

Thu, 11 Aug 2016 12:16:28 -0700


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!

Tue, 09 Aug 2016 18:13:23 -0700


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!

Sun, 07 Aug 2016 16:21:33 -0700


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?

Cyber Grand Challenge Highlights from DEF CON 24!

Sat, 06 Aug 2016 14:31:09 -0700


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

Wed, 03 Aug 2016 18:03:30 -0700


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

Fri, 29 Jul 2016 19:01:08 -0700


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.

DEF CON Darknet Project

Sun, 17 Jul 2016 15:43:12 -0700


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!

Sat, 09 Jul 2016 03:06:46 -0700


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

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

Mon, 27 Jun 2016 17:00:59 -0700


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. 

New Speaker's Corner post!

Thu, 23 Jun 2016 12:03:21 -0700

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

Mon, 06 Jun 2016 10:24:25 -0700


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 Homework Continues!

Fri, 01 Apr 2016 08:18:39 -0700

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. Moon 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. 2001 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.) [...]
