River Cree Resort And Casino's Employee, Customer Info Stolen

EDMONTON — Officials at an Edmonton-area casino are doing damage control after finding out they were the target of a cyberattack that put employee and customer information at risk.

Over the weekend, computer systems at the River Cree Resort and Casino went down, but what happened wasn't made clear until this week.

General manager Vik Mahajan says at first they thought it was a technical failure but later realized it was an actual attack.

He says there was theft of customer and employee information — though he won't say how many people are involved — but the incident didn’t affect the casino floor.

Officials say as soon as the attack was discovered, police were contacted, along with cyber security experts at a private company.

Mahajan wouldn’t say what type of cyberattack took place, or what information was compromised.

“We’re trying to sift through all that,” Mahajan says. “I know there’s some personal information in our system that would relate to associates as well as customers and how much of that information is gone, we are trying to determine that.”

River Cree has been contacting people whose information may have been compromised.

The Alberta Gaming and Liquor Commission has been contacted, and is investigating as well.
