This article from Wired tells the story of a hacker / engineer who was able to successful override a Deckmate 2’s security to create a cheatable shuffler.

Fascinating read.

Kinda surprised these don’t get more attention. The coolest one I saw posted were the programmable decks that could be read from the side view by phone cameras. Search on here is boo boo so it’s hard to find but was a crazy video.

This article has been posted on here 4 times now but no one is replying or discussing.

Which again feels weird. If I’m sitting down and buying in for $1k, $2k, or 500k, makes me a little uncomfy.

Even if you know for 99% certainty that your straight flush over straight flush was clean and everyone’s a “great guy”, I wonder if folks playing in games that big don’t pause for a second with large 6 figure amounts changing hands.

I think it’s because most of us knew it was possible on some level anyway? So what are you gonna do?
There was a lot of talk about these a couple years ago regarding Texas poker. (You may have been banned at the time - even odds.) most of us came away from that discussion saying that since Texas rooms aren’t regulated and since these things can be hacked, don’t play with deckmates in Texas. And to be fair, there were always a couple of guys who swore they’d never play with deckmates in Vegas or anywhere else.
Now it’s a little uglier, if these can be hacked via usb or WiFi - how much damage could be done before the state regulators figure it out? Lots, I’d think. I mean how often are they actually checked? And even so, the article alludes that checking it may be as lame as asking the machine if it’s been tampered with?
So yeah, our “state regulation” pacifiers may not actually be useful protection. I don’t think I’ll lose sleep over it. This is just another angle to watch out for. Not sure how easily I can tell the difference between bad luck and cheating, but it’s always in the back of my mind.
 
The USB port is used for the external display and control screen. They might have to go back to install the display in future models on the shuffler itself so they won't have external ports. I wonder if they did try to deploy this hack in a live Casino would they be able to catch them since the screen will shut off in order to plug the raspberry pi in.
 
the deck is cut, so do cheaters need the dealer in on it?
I don't think so. If the card order of the stub is known pre-cut (along with the number of players), the actual order of the cut deck stub can be determined -- along with all dealt hands -- once the flop has been exposed (including what cards will appear on the turn and river).
 
I work in Cyber/Information security,

This is just basic, everythink electronic can be hacked if you get physical access to it via USB port. It is unlikley that home game shufflers are hacked but when playing High stakes hand dealt is better...

Most industries are so far behind on infosec. :(

put a cover that needs to be screwed in over the usb ports and that should cover the "stick a device into the USB port" issue.

Even better, just super glue it shut.
 
I'm assuming it's needed for some sort of firmware updates/etc. Cause if they remove it they'll make it networked and then everything gets 1000% worse lol
Prediction: Deckmate 3 will be networked to enforce a subscription service pricing model (remote bricking). Then it'll get pwned at Black Hat again while manufacturer and casinos say "what design flaw?"
 
One of many reasons I don’t play at underground raked games around the tri-state area here on the east coast (sometimes I’m forced to when there’s no other game running but it’s a rare occasion). I’m very skeptical by nature that the people that are drawn to running their own high stakes games, will not at least try to experiment with something (shufflers, marked decks, ink etc)
 
The designers of these high tech devices got so enamored with whether they COULD provide fancy features, they didn’t stop to think whether they SHOULD. The unintended consequences committee was utterly sidelined.

I don’t trust Deckmate 2s not one bit.
 
What about smart watches? Fitbits? Smartrings? Vibrating buttplugs?
I gave some thought to the smart watch. The cheat here is reading an entire deck. I'm sure some speed-reading memory-champion may be able to scan their watch for every card and remember it, but those people will be very few.

No protection will be 100% safe. The goal is to make the challenge greater than the reward.

No electronic devices while in a hand isn't unenforceable. It used to be the way, but they bent the rule for the instagram crowd. Bend it back - just a little. You can read your phone, check your electronic GTO charts, take stack pics, text your buddy at the other end of the table, whatever. Just not in a hand.

Or, they have someone offsite doing that, and sends them a text that makes their phone buzz if they should raise/fold/etc

Well, it doesn’t have to be that hard. Ever use Delands Magic Deck? You arrange the cards, starting with a number and suit, and then progressively build each card one suit different and three pips higher.
Say your suits order is SDCH
Your first card would be 3S. Your next would be 6D, then 9C,… etc. you can vary the pip spacing and/or the count to stack it in various ways. The only trick then is to see the bottom card after the cut. Then you can figure them all without memorizing anything.
Deckmate could do this or any variation action easy peasy.

Anyone that plays cards should read the Delands instructions. It’s an eye opener.
 
I haven't read the article but I'm certain that they (the researchers) found a vulnerability in the deckmate's software that allowed them to leverage the USB connection to run unsigned/insecure code. doesn't mean USB port on a shuffler is dumb or bad or needs to be filled with hot glue (yes, it's another vector but provides useful features), it means they (deckmate or whatever) should take a little harder look at how they're handling peripherals

Good chance it's been exploited in the wild but the wonderful thing about hackers (in the true sense of the word) is that they explore these things and help make systems stronger
