Stolen Casino Rama customer data has surfaced online one day after the casino announced it had been the victim of a cyberattack.

On Thursday, Ontario’s Casino Rama announced that an “anonymous threat agent” had infiltrated its data networks and made off with “past and present customer, employee and vendor information” dating as far back as 2004. The company became aware of the breach on November 4.

On Friday, Toronto’s CityNews reported that the anonymous hacker had posted some of the stolen data online, along with a warning that the entire data trove would be posted within 72 hours.

The hacker’s post included a note saying it was “extremely simple” to access Casino Rama’s files and that “no security systems were in place leaving the whole casino network wide open.” The hacker slammed the casino for convincing the public “that they take the protection of data and customer information seriously when really they don’t.” Neither the hacker nor Casino Rama have so far publicly indicated that the breach was part of an attempt to extort the casino.
