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

DEF CON In the Media: Coded Web Series

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


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

Announcing the DEF CON 25 Theme!

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

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

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

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

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

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

Connected Weapons: Warfare and the Future

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


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

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

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

A Gift for You!

Fri, 16 Dec 2016 23:13:30 -0800

IoT in the News: Through the Back Door

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


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

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

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

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

Enjoy, share widely and run the latest firmware.

Exclusive DEF CON 25 Swag Pack!

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

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


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

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

Check it out, pass it on.

DEF CON Speaker in the News

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


DEF CON 24 Speaker Patrick Wardle is back in the news with a warning about Shazam's macOS app. Apparently, turning off the app doesn't stop it from recording.

Which is weird, right?

If reading the article has you looking for a little more of Patrick's insights into macOS security, you can check out his talk 'I've Got 99 Problems, Little Snitch Ain't One.' from DC24.

Mon, 07 Nov 2016 16:35:12 -0800


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.

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

DC530 (Chico, CA) now meets every Tuesday!

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


From their Facebook page:

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

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

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

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

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

Medical Device Security, and the Possibilities

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

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

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

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

Link to the insulin pump story:

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

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


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

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

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

As always, watch, learn and share widely.

DEF CON 24 Contest Results are Live!

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


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

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

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

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.

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 Sine Qua Non[...]

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.

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. Westworld: 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.  Hardware: 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. Runaway: 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. [...]

DEF CON Lucknow Update

Thu, 16 Jun 2016 14:04:03 -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.
