Molson Coors, one of the nation's largest beer makers, halted production this week after hackers disrupted company operations.
In a regulatory filing, company officials said the cyberattack has taken its systems offline, and delayed production and shipments. Details about the nature of the attack were not disclosed.
"Molson Coors experienced a systems outage that was caused by a cybersecurity incident," the company said in a statement.
The company is looking into the incident and is working to get systems back up as quickly as possible. A forensic IT firm is assisting with the investigation.
