Sparrowvsrevolution writes "You may remember a vulnerability in four million keycard locks presented at the Black Hat conference in July. Hacker Cody Brocious showed he could insert a device he built for less than $50 into the port at the bottom of the common hotel lock, read a key out of its memory, and open it in seconds. Two months later, it turns out at least one burglar was already making use of that technique to rob a series of hotel rooms in Texas. The Hyatt House Galleria in Houston has revealed that in at least three September cases of theft from its rooms, the thief used that Onity vulnerability to effortlessly open rooms and steal valuables like laptops. Petra Risk Solutions, an insurance firm focus the hospitality industry also reports that at least two other hotels in Texas were hit with the attack. Onity has been criticized for its less-than-stellar response to a glaring vulnerability in its devices. The Hyatt says Onity didn't provide a fix until after its break-ins, forcing the hotel to plug its locks' ports with epoxy. And even now, Onity is asking its hotel customers to pay for the full fix, which involves replacing the locks' circuit boards."
