At the Black Hat conference, Brocious showed it was possible to insert the plug of a small device he built with less than $50 in parts into the port at the bottom of any Onity keycard lock, read the digital key that provides access to the opening mechanism of the lock, and open it instantaneously.
White Lodging contends that Onity only implemented a fix for that flaw in its locks after the September break-ins at the Houston Hyatt, around two months after Andy Greenberg, the Forbes reporter, first alerted Onity to Brocious’s work.
