More Black Hat/DEFCON 26 updates.

Wednesday, August 15th, 2018
  • Slides for “A Dive in to Hyper-V Architecture & Vulnerabilities” with Joe Bialek and Nicolas Joly can be found here. (The link on the Black Hat site is still borked.)
  • This isn’t an actual DEFCON 26 presentation, but it’s referenced in Vincent Tan’s “Hacking BLE Bicycle Locks for Fun and a Small Profit”, and I want to bookmark it for later: “Blue Picking: Hacking Bluetooth Smart Locks” by Slawomir Jasek.
  • Slides for “Ring 0/-2 Rookits: Compromising Defenses” with Alexandre Borges are here.
  • Also not a DEFCON presentation, but picked up by way of an Ars Technica story: “Fear the Reaper: Characterization and Fast Detection of Card Skimmers” by Nolen Scaife, Christian Peeters, and Patrick Traynor. In which the authors analyze a bunch of skimmers confiscated by NYPD…and then build a device that can detect skimmers, based on nothing more than the physical properties of how card readers work. Quote of the day: “Security solutions requiring significant behavioral changes are unlikely to be successful.”
  • Content for “All your math are belong to us” with sghctoma is here: slides, white paper, and exploit code.

DEFCON 26/Black Hat updates: August 14, 2018.

Tuesday, August 14th, 2018

I apologize that I wasn’t able to post more coverage over the weekend: as I expected, it turned out to be fun, but packed.

I intended to post this yesterday, but I wasn’t able to find many updates on my lunch hour. Then I got stuck in a gumption trap late in the day at work, and basically came home and collapsed.

In retrospect, that was better, because this story broke late in the afternoon: Caesars Palace security was (in the opinion of at least some DEFCON attendees) a little too aggressive about searching rooms. More from Defiant, a company that was at DEFCON. Statement from Marc Rogers.

Good post with links over at Borepatch’s site about the widely covered “voting machine vulnerabilities”.

Also: badge related coverage if you care. Personally, I don’t need a stinking badge.

Another Ars story based on another Black Hat panel:

Life-saving pacemakers manufactured by Medtronic don’t rely on encryption to safeguard firmware updates, a failing that makes it possible for hackers to remotely install malicious wares that threaten patients’ lives, security researchers said Thursday.

The presentation in question is “Understanding and Exploiting Implanted Medical Devices” by Billy Rios and Jonathan Butts. No slides or white paper yet, so I don’t want to comment very much. But: I do also want to point out this article, “The $250 Biohack That’s Revolutionizing Life With Diabetes“. Why? Well…

The DIY pancreas movement would never have happened if not for a Medtronic blunder. In 2011 a pair of security researchers alerted the public that the wireless radio frequency links in some of the company’s best-selling insulin pumps had been left open to hackers. Medtronic closed the loophole after the researchers warned of risks to patients, but it never recalled the devices, leaving thousands in circulation.

Some additional interesting looking work:

  • “TRITON: How it Disrupted Safety Systems and Changed the Threat Landscape of Industrial Control Systems, Forever” by Andrea Carcano, Marina Krotofil, and Younes Dragoni. “In 2017, a sophisticated threat actor deployed the TRITON attack framework engineered to manipulate industrial safety systems at a critical infrastructure facility. This talk offers new insights into TRITON attack framework which became an unprecedented milestone in the history of cyber-warfare as it is the first publicly observed malware that specifically targets protection functions meant to safeguard human lives.” Slides. White paper.
  • There will be Glitches: Extracting and Analyzing Automotive Firmware Efficiently” by a whole bunch of people.
  • And it just wouldn’t be a security conference in 2018 without a Tesla attack: “Over-the-Air: How we Remotely Compromised the Gateway, BCM, and Autopilot ECUs of Tesla Cars” by Ling Liu, Sen Nie, Wenkai Zhang, and Yuefeng Du. White paper is at the link: slides are broken.

That’s all I’ve been able to turn up today. More tomorrow, I hope.

Black Hat 2018/DEFCON 26 0 day updates.

Thursday, August 9th, 2018

Some of yesterday’s Black Hat presentations:

Some others that I didn’t get to the first time around:

  • “Software Attacks on Hardware Wallets” by Alyssa Milburn and Sergei Volokitin. “…we show how software attacks can be used to break in the most protected part of the hardware wallet, the Secure Element, and how it can be exploited by an attacker.” Slides. White paper.
  • “Screaming Channels: When Electromagnetic Side Channels Meet Radio Transceivers” with a whole big bunch of folks. “…we show that it is possible to recover the original leaked signal over large distances on the radio. As a result, variations of known side-channel analysis techniques can be applied, effectively allowing us to retrieve the encryption key by just listening on the air with a software defined radio (SDR).” Slides. White paper.

Ars Technica has a story up in advance of Justin Shattuck’s “Snooping on Cellular Gateways and Their Critical Role in ICS” presentation later today:

…many of the unsecured gateways were installed in police cars, ambulances, and other emergency vehicles. Not only were the devices openly broadcasting the locations of these first responders, but they were also exposing configurations that could be used to take control of the devices and, from there, possibly control dash cameras, in-vehicle computers, and other devices that relied on the wireless gateways for Internet connections.

There are a couple of other presentations from yesterday that sound interesting on second look, but the links to them are currently broken. Also, I haven’t had a chance to read through all of these yet: I did give a quick skim to “Stress and Hacking” and “Reversing a Japanese Wireless SD Card” and look forward to a more careful read of both.

I think I’m going to try to post a second update later this evening if the broken links are fixed and/or new content is available. We should also be getting close to the point where the DEFCON 26 media server has preliminary versions of the presentations up…

Edited to add: DEFCON 26 presentations are now live on the DEFCON media server.

DEFCON 26/Black Hat 2018 preliminary notes.

Sunday, August 5th, 2018

DEFCON 26 and Black Hat 2018 start up later this week. Again, I’m not going, but I do feel like I’m inching closer to making a return. Full-timers from my group have been sent to Black Hat in the past, so who knows what’s going to happen next year?

What would I do if I was there? A quick skim of the Black Hat briefings schedule doesn’t show a whole lot that really jumps out at me. I’d probably just be hitting targets of opportunity, with a few exceptions:

What about DEFCON 26? After the jump…

DEFCON 25 update: August 3, 2017.

Thursday, August 3rd, 2017

Mike the Musicologist tipped me off to this:

Marcus Hutchins, the guy who was in the news earlier this year for defusing the WCry malware, was detained in Las Vegas after DEFCON.

This is still an evolving story, but what I’ve seen from reliable sources (and CNN) is that Hutchins is under federal indictment and charged with creating another piece of malware: Kronos, described as a “banking Trojan”.

The best coverage I’ve seen of this so far is from TechDirt and ArsTechnica. I would keep an eye on those two sites for updates, as this story is still evolving.

DEFCON 25 updates: July 31, 2017.

Monday, July 31st, 2017

Things are going to be a little busy this week, but I do plan to keep an eye out for updates. In the meantime, please enjoy this latest set:

  • TJ Horner has a nice blog post up about his experiences hacking voting machines in DEFCON 25’s “Voting Village”.
  • “The Adventures of AV and the Leaky Sandbox” (Itzik Kotler and Amit Klein) didn’t catch my attention the first time around, but the abstract sounds intriguing: “In this presentation, we describe and demonstrate a novel technique for exfiltrating data from highly secure enterprises whose endpoints have no direct Internet connection, or whose endpoints’ connection to the Internet is restricted to hosts used by their legitimately installed software. Assuming the endpoint has a cloud-enhanced antivirus product installed, we show that if the anti-virus product employs an Internet-connected sandbox in its cloud, it in fact facilitates such exfiltration.” Slides. White paper. GitHub repo.
  • GitHub repo (including slides and white paper) for the Marc Newlin/Logan Lamb/Chris Grayson presentation, “CableTap: Wirelessly Tapping Your Home Network”.
  • Here’s some stuff from “Tracking Spies in the Skies” (Jason Hernandez, Sam Richards, Jerod MacDonald-Evoy): North Star Post summary of their presentation. GitHub repo.
  • Slides from the David Robinson talk, “Using GPS Spoofing to control time”, are here. Slides contain links to code, per Mr. Robinson. I’ve only had a chance to take a quick look at this, but I’m fascinated.

DEFCON 25 updates: July 29, 2017.

Saturday, July 29th, 2017

Third round. I’m not proud. Or tired.

DEFCON 25/Black Hat updates: July 28, 2017.

Friday, July 28th, 2017

Round 2:

  • The white paper for “Free-Fall: Hacking Tesla from Wireless to CAN Bus” (Ling Liu, Sen Nie, Yuefeng Du) is here. Slides here.
  • Slides for “Exploiting Network Printers” (Jens Müller, Vladislav Mladenov, Juraj Somorovsky, Jörg Schwenk) are here.
  • Found slides for “Breaking Electronic Door Locks Like You’re on CSI: Cyber” here. (I called this one wrong: no Bluetooth. Not a complaint, just an observation.)
  • This is one that I saw, overlooked, and now am intrigued by: “All Your SMS & Contacts Belong to ADUPS & Others“. “Our research has identified several models of Android mobile devices that contained firmware that collected sensitive personal data about their users and transmitted this sensitive data to third-party servers in China – without disclosure or the users’ consent.” Slides. White paper.
  • Slides for Vlad Gostomelsky’s “Hunting GPS Jammers”. I think this is one that really needs video, too.
  • “Intercepting iCloud Keychain” (Alex Radocea) slides.
  • And “The Future of ApplePwn – How to Save Your Money” (Timur Yunusov) slides.
  • And (hattip to Mr. Yunusov) “Jailbreaking Apple Watch” (Max Bazaliy). I haven’t compared these slides to the onea on the presentations server, just FYI.

Okay, lunch time is almost over, and I feel like I’ve done enough damage to the security community today. I’ll try to have more updates later today or tonight.

DEFCON 25/Black Hat updates: July 27, 2017.

Thursday, July 27th, 2017

Round 1:

Edited to add more:

  • Karla Burnett’s “Ichthyology: Phishing as a Science” is actually relevant to my professional life. White paper.
  • Slides and the white paper for “Hacking Hardware with a $10 SD Card Reader” (Amir Etemadieh, CJ Heres, and Khoa Hoang) are here.

Here’s your hat.

Wednesday, July 26th, 2017

Black Hat 2017 is just getting started.

There’s some overlap with DEFCON 25. For example, hacking wind farm control networks and the SHA-1 hash talk are on both schedules. But there are also a few things unique to the Black Hat 2017 schedule:

The same rules for the DEFCON post apply here: if you’re a presenter who wants some love, or if you want me to follow a specific talk, leave a comment.

DEFCON 25: 0 day notes.

Tuesday, July 25th, 2017

I’m not going again this year. Maybe next year, if things hold together. But if I were going, what on the schedule excites me? What would I go to if I were there?

Thursday: neither of the 10:00 panels really grab me. At 11:00, maybe “From Box to Backdoor: Using Old School Tools and Techniques to Discover Backdoors in Modern Devices” but I’m at best 50/50 on that. At 12:00, I feel like I have to hit the “Jailbreaking Apple Watch” talk. “Amateur Digital Archeology” at 13:00 sounds mildly interesting.

Not really exited by anything at 14:00. At 15:00, I suspect I would end up at “Real-time RFID Cloning in the Field” and “Exploiting 0ld Mag-stripe information with New technology“. And 16:00 is probably when I’d check out the dealer’s room again, or start getting ready for an earlyish dinner.

Friday: 10:00 is sort of a toss-up. THE Garry Kasparov is giving a talk on
The Brain’s Last Stand” and as you know, Bob, chess is one of my interests. On the other hand, there’s also two Mac specific talks, and Kasparov’s talk is probably going to be packed: I suspect I’d hit “macOS/iOS Kernel Debugging and Heap Feng Shui” followed by “Hacking travel routers like it’s 1999” (because I’m all about router hacking, babe). Nothing grabs me at 11:00, but I do want to see “Open Source Safe Cracking Robots – Combinations Under 1 Hour!” at 12:00:

By using a motor with a high count encoder we can take measurements of the internal bits of a combination safe while it remains closed. These measurements expose one of the digits of the combination needed to open a standard fire safe. Additionally, ‘set testing’ is a new method we created to decrease the time between combination attempts. With some 3D printing, Arduino, and some strong magnets we can crack almost any fire safe.

13:00: “Controlling IoT devices with crafted radio signals“, and “Using GPS Spoofing to control time” at 14:00. (I do want to give a shout-out to the Elie Bursztein talk, “How we created the first SHA-1 collision and what it means for hash security“, though.)

Do I want to go to “Phone system testing and other fun tricks” at 15:00? Or do I want to take a break before “Radio Exploitation 101: Characterizing, Contextualizing, and Applying Wireless Attack Methods“:

As we introduce each new attack, we will draw parallels to similar wired network exploits, and highlight attack primitives that are unique to RF. To illustrate these concepts, we will show each attack in practice with a series of live demos built on software-defined and hardware radios.

And then at 17:00, “Cisco Catalyst Exploitation” is relevant to my interests. However, I don’t want to dismiss “The Internet Already Knows I’m Pregnant“:

…EFF and Journalist Kashmir Hill have taken a look at some of the privacy and security properties of over a dozen different fertility and pregnancy tracking apps. Through our research we have uncovered several privacy issues in many of the applications as well as some notable security flaws as well as a couple of interesting security features.

Saturday: Nothing at 10:00. At 10:30, maybe “Breaking Wind: Adventures in Hacking Wind Farm Control Networks” because why not?

I have to give another shout-out to “If You Give a Mouse a Microchip… It will execute a payload and cheat at your high-stakes video game tournament” but I’m personally more interested in “Secure Tokin’ and Doobiekeys: How to Roll Your Own Counterfeit Hardware Security Devices” at 11:00. (“All Your Things Are Belong To Us” sounds pretty cool, too, but I’d probably wait for the notes/repos/etc. to be released rather than attending in person.)

Oddly, there’s really nothing that grabs me between 12:00 and 15:00. At 15:00, “Tracking Spies in the Skies” mildly intrigues me (mostly for the ADS-B aspect), while at 16:00 I’m really excited by “CableTap: Wirelessly Tapping Your Home Network” (more home router hacking! Hurrah!)

At 17:00:

In this talk, we explore the security of one of the only smart guns available for sale in the world. Three vulnerabilities will be demonstrated. First, we will show how to make the weapon fire even when separated from its owner by a considerable distance. Second, we will show how to prevent the weapon from firing even when authorized by its owner. Third, we will show how to fire the weapon even when not authorized by its owner, with no prior contact with the specific weapon, and with no modifications to the weapon.

You have my attention.

(Related article from Wired. Presenter’s Twitter feed.)

Sunday: “I Know What You Are by the Smell of Your Wifi“, followed a little later by “Backdooring the Lottery and Other Security Tales in Gaming over the Past 25 Years“.

Weirdly, after that, there’s nothing that interests me until the closing ceremonies at 16:00. (Though I might go to “Man in the NFC” if I was there.)

This seems like a very low-key year, and I’m not sure why. I don’t see any Bluetooth related stuff, and very little lock related. Perhaps I should be glad I’m skipping this year.

Anyway, you guys know the drill: if you see a talk you’re interested in, leave a comment and I’ll try to run it down. If you’re a presenter who wants to promote your talk, leave a comment and I’ll try to give you some love.

Curses!

Tuesday, July 25th, 2017

DEFCON 25 is this week, and it snuck up on me. I was expecting it to start next week.

I guess this means I have to get the schedule analysis up in a hurry. I think I can get it done by Wednesday night; or at least get the Thursday/Friday parts of it up, and Saturday/Sunday up by Thursday night.

Is there anything that leaps out at me from a quick once-over? No “hippie, please!” panels that I noticed this year. Also no badge contest or mystery challenge.

(Also, I’m reorging the DEFCON tags. I think this should be transparent to everyone.)

Actually, they can read your poker face.

Wednesday, October 26th, 2016

Or at least your cards.

This is a presentation that I overlooked from DEFCON 24, but the authors have now been blogging.

For somewhere between $1,300 and $5,000, you can buy a device that helps you cheat at poker.

The technology is quite interesting. It isn’t just “disguised” as a phone: the device is actually a fully functional Android phone, with a custom ROM and app that controls the cheating portion.

Ironically, there is a hardcoded backdoor password in the app, which makes this security measure pointless if you know the backdoor password.

How does it work? Hidden camera, concealed infrared LEDs, and…

What makes the whole thing work is the use of a special deck in which the four edges of each card are marked with IR-absorbing ink. As a result, when this marked deck is illuminated by the IR LEDs, the spots of ink absorb the IR, creating a sequence of black spots…
The sequence of black spots created by the IR illumination, illustrated in the photo above, is read remotely by the cheating device to infer a card’s suit and value. You can think of those markings as invisible barcodes.

So yes, you do need to slip in a marked deck. But the people who will sell you the phone will also sell you pre-marked decks, which are designed to look like they haven’t been messed with. And apparently the phone will pair with Bluetooth based audio and haptic feedback devices, so you don’t even have to be looking at the display.

And yes, because it is based on marked cards, it will work with card games other than poker, too. (High-end bridge cheating? Chris Christie, call your office, please. Sorry, little joke there.)

The post that’s up now is just the first one in a promised series: I’ll try to link to the other ones as they go up.

DEFCON 24 updates: August 11, 2016.

Thursday, August 11th, 2016

“SITCH – Inexpensive, Coordinated GSM Anomaly Detection” doesn’t just have slides up. Or a whitepaper.

It has an entire freaking website. Which does include, yes, slides and whitepaper. (Thanks to SecBarbie on Twitter for this.)

Slides for the Tamas Szakaly “Help, I’ve got ANTs!!!” talk are here. And his GitHub repo is here.

Good stuff is going up on the Black Hat 2016 briefings site, too. I haven’t had a chance to go through all of the abstracts yet, but my current favorite is: “Does Dropping USB Drives In Parking Lots And Other Places Really Work?”. Slides here, code here, blog post here, no spoilers here.
