In September final 12 months, a scandal blew up the world of high-stakes, livestreamed poker: In a hand at Las Vegas’ Hustler Live 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 called the bluff of a veteran player. No one may presumably suppose that poor hand is likely to be ok to name a bluff, 1000’s of outraged poker gamers argued, except the particular person holding it had some additional data that her opponent’s hand was even worse—in different phrases, she will need to have been dishonest.
Three months later, Hustler Live Casino printed a postmortem of its investigation into the incident, discovering “no credible evidence” of foul play. It additionally famous that if there have been dishonest, it was most probably some type of secret communication between the participant and a employees member within the manufacturing sales space who may see the gamers’ palms in actual time. But when Joseph Tartaro, a researcher and marketing consultant with safety agency IOActive, learn that report, he zeroed in on one declare specifically—an announcement ruling out any risk 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 secure and cannot be compromised,” the report learn.
To Tartaro, no matter what occurred within the Hustler Live hand, that assertion of the shuffler’s good safety was an irresistible invitation to show in any other case. “At that point, it’s a challenge,” Tartaro says. “Let’s look at one of these things and see how realistic it really is to cheat.”

Today, 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 at the moment. They finally 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 usually sits below 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 inner digicam designed to make sure that each card is current within the deck, and that they may acquire entry to that digicam to study the complete order of the deck in actual time, sending the outcomes from their small hacking system by way of Bluetooth to a close-by cellphone, doubtlessly held by a associate who then may then ship coded indicators to the dishonest participant.
In sum, their shuffler hacking method provides a cheater “100 percent full control,” says Tartaro, who demonstrates IOActive’s findings within the video under. “Basically, it allows us to do more or less whatever we want … We can, for example, just read the constant data from the camera so we can know the deck order, and when that deck goes out into play, we know exactly the hand that everyone is going to have.”
For now, the IOActive researchers say they have not but had time to engineer a method that may trigger the Deckmate to place the deck within the precise order of their selecting—though they’re sure that too could be doable. Regardless, they argue, merely understanding the total card order, slightly than altering it, provides an much more sensible dishonest technique, one which’s far more durable 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 Hold’em, the favored model of poker performed in most casinos, together with within the infamous Hustler Live Casino hand. That’s as a result of in Texas Hold’em, understanding the order of a deck would enable somebody to foretell the precise make-up of everybody’s hand, impartial of any choices they make within the sport. Even if a vendor 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 of instantly determine the order of the playing cards on the highest of the deck and in each participant’s palms as quickly because the three “flop” playing cards are uncovered—the public-facing, shared playing cards dealt out originally of a Hold’em hand.
The IOActive workforce additionally appeared on the earlier mannequin of the Deckmate, generally known as the Deckmate 1, which has no exterior USB port and no inner digicam. The researchers say that the sooner mannequin, which was the one really used within the Hustler Live Casino sport, may nonetheless nonetheless be hacked to cheat in a sport if a rogue on line casino staffer or upkeep particular person had a possibility to open the shuffler’s case and entry a selected chip that shops its code. In that case, regardless of the shortage of an inner digicam, the cheater may nonetheless hack the shuffler to reorder playing cards—or they may merely stop the Deckmate from shuffling the deck when a vendor picks up everybody’s playing cards after a hand, giving the cheater details about the placement of these beforehand performed playing cards. “A skilled player with that little bit of an edge would 100 percent clean up,” says Tartaro.
