In September final yr, a scandal blew up the world of high-stakes, livestreamed poker: In a hand at Las Vegas’ Hustler Dwell On line casino, which broadcast its video games on YouTube, a relative novice holding nothing however a jack of golf equipment and a 4 of hearts efficiently referred to as the bluff of a veteran participant. Nobody may presumably assume that poor hand could be adequate to name a bluff, hundreds of outraged poker gamers argued, except the particular person holding it had some further information that her opponent’s hand was even worse—in different phrases, she should have been dishonest.
Three months later, Hustler Dwell On line casino revealed a postmortem of its investigation into the incident, discovering “no credible proof” of foul play. It additionally famous that if there have been dishonest, it was more than likely some type of secret communication between the participant and a workers member within the manufacturing sales space who may see the gamers’ arms in actual time. However when Joseph Tartaro, a researcher and guide with safety agency IOActive, learn that report, he zeroed in on one declare specifically—a press release ruling out any chance that the automated card-shuffling machine used on the desk, a tool generally known as the Deckmate, may have been hacked. “The Deckmate shuffling machine is safe and can’t be compromised,” the report learn.
To Tartaro, no matter what occurred within the Hustler Dwell hand, that assertion of the shuffler’s good safety was an irresistible invitation to show in any other case. “At that time, it is a problem,” Tartaro says. “Let’s take a look at one in every of this stuff and see how sensible it truly is to cheat.”

At the moment, on the Black Hat safety convention in Las Vegas, Tartaro and two IOActive colleagues, Enrique Nissim and Ethan Shackelford, will current the outcomes of their ensuing months-long investigation into the Deckmate, probably the most broadly used automated shuffling machine in casinos as we speak. They in the end discovered that if somebody can plug a small system right into a USB port on probably the most trendy model of the Deckmate—generally known as the Deckmate 2, which they are saying typically sits underneath a desk subsequent to gamers’ knees, with its USB port uncovered—that hacking system may alter the shuffler’s code to completely hijack the machine and invisibly tamper with its shuffling. They discovered that the Deckmate 2 additionally has an inside digicam designed to make sure that each card is current within the deck, and that they might achieve entry to that digicam to study the complete order of the deck in actual time, sending the outcomes from their small hacking system through Bluetooth to a close-by cellphone, probably held by a companion who then may then ship coded alerts to the dishonest participant.
In sum, their shuffler hacking method offers a cheater “100% full management,” says Tartaro, who demonstrates IOActive’s findings within the video under. “Principally, it permits us to do kind of no matter we wish … We are able to, for instance, simply learn the fixed knowledge from the digicam so we are able to know the deck order, and when that deck goes out into play, we all know precisely the hand that everybody goes to have.”
For now, the IOActive researchers say they have not but had time to engineer a way that may trigger the Deckmate to place the deck within the actual order of their selecting—though they’re sure that too could be doable. Regardless, they argue, merely figuring out the total card order, moderately than altering it, presents an much more sensible dishonest technique, one which’s far tougher to detect.
Tartaro says the method might be used to cheat in any variety of card video games, however that it could be notably highly effective in Texas Maintain’em, the favored model of poker performed in most casinos, together with within the infamous Hustler Dwell On line casino hand. That is as a result of in Texas Maintain’em, figuring out the order of a deck would enable somebody to foretell the precise make-up of everybody’s hand, impartial of any selections they make within the recreation. Even when a supplier cuts the deck earlier than dealing, as most do in high-stakes on line casino video games, Tartaro says the dishonest participant would nonetheless be capable to instantly work out the order of the playing cards on the highest of the deck and in each participant’s arms as quickly because the three “flop” playing cards are uncovered—the public-facing, shared playing cards dealt out firstly of a Maintain’em hand.
The IOActive crew additionally appeared on the earlier mannequin of the Deckmate, generally known as the Deckmate 1, which has no exterior USB port and no inside digicam. The researchers say that the sooner mannequin, which was the one really used within the Hustler Dwell On line casino recreation, may nonetheless nonetheless be hacked to cheat in a recreation if a rogue on line casino staffer or upkeep particular person had a possibility to open the shuffler’s case and entry a specific chip that shops its code. In that case, regardless of the dearth of an inside digicam, the cheater may nonetheless hack the shuffler to reorder playing cards—or they might merely stop the Deckmate from shuffling the deck when a supplier picks up everybody’s playing cards after a hand, giving the cheater details about the placement of these beforehand performed playing cards. “A talented participant with that little little bit of an edge would 100% clear up,” says Tartaro.
