Doug Polk has issued a warning to poker players about the risks of card shuffling machines in private games or unlicensed card rooms — saying you should “run for the hills” if you see them being used.

Polk made the comment during an interview for a new WIRED video, in which journalist Andy Greenberg revisited an earlier investigation into the vulnerability of automatic shuffling machines — specifically, the Deckmate 2 — and how they can be hacked to facilitate cheating.

The Deckmate 2 is one of the most commonly used automatic card shufflers in the world, found at the WSOP and in casinos around the world. It includes an internal camera capable of scanning and delivering the full order of a shuffled deck in real time to a connected device — information that can be exploited to cheat during a poker game.

Greenberg first reported on a hack of the Deckmate 2 two years ago. By accessing the machine’s USB port, researchers were able to bypass security protocols and alter its code to "hijack the machine and invisibly tamper with its shuffling." Even without the USB port, someone with access to the machine's internal components could set it up for cheating.
