Description
Maple Leaf Foods, Canada's largest prepared meats and poultry producer, experienced a cybersecurity incident during the weekend of November 5-6, 2022, which triggered a system outage and operational disruptions. The company publicly confirmed the incident on November 7, noting that its IT team immediately activated response protocols despite attackers likely targeting the weekend period to exploit potential staffing vulnerabilities. With annual sales of $3.3 billion in 2021, operations spanning 21 manufacturing facilities, 14,000 employees, and over 700 contracted barns, the outage created varying levels of disruption across different business units, plants, and operational sites. The organization implemented its business continuity plans while working to restore affected systems, acknowledging that full recovery would require extended time and result in continued service interruptions. Maple Leaf Foods prioritized minimizing supply chain impacts, maintaining communication with customers and partners to mitigate food distribution disruptions across Canadian markets.
Specialists from the company collaborated with external cybersecurity and recovery experts to contain the incident and restore operations. The investigation remained ongoing at the time of the initial announcement, with the organization explicitly stating it had not yet determined the root cause or method of intrusion. No ransomware group or cybercrime forum had claimed responsibility for the attack as of the report date, and the company confirmed no evidence suggested partner organizations were compromised through this incident. Operational impacts persisted during recovery efforts, though the firm focused on gradual system restoration while maintaining transparency about the extended resolution timeline required for complete recovery. Maple Leaf Foods emphasized its commitment to resolving the situation systematically without elaborating on technical specifics of the attack or restoration process.
