Supermarket Freezers in Belgium and Sweden Hit by Suspected Cyber-Attack

Overview of the Incident

Dozens of supermarkets across Belgium and Sweden, alongside locations in Ireland, have experienced temperature malfunctions in their refrigeration and freezer units following a suspected cyber-attack. The incident has forced retailers to discard significant amounts of perishable food and temporarily alter store operations.

Impact by Region and Retailer

According to initial reports, the disruptions affected multiple major grocery chains:

• Belgium: Approximately 40 Delhaize supermarkets and 15 Carrefour stores reported issues.
• Sweden: Several ICA and Coop locations experienced disruptions. Out of roughly 800 Coop stores, seven were impacted, though the company stated the situation is now contained and under control.
• Ireland: Thirteen SuperValu shops were also reportedly affected.

Nature of the Disruption

Retailers and local media have highlighted the operational challenges caused by the temperature alterations:

• Local media reported that thousands of euros worth of food had to be discarded.
• A social media post from an ICA branch in Sjöbo, southern Sweden, stated that unit temperatures were maliciously altered to 50°C (122°F) overnight. The affected branch temporarily closed before reopening to customers.
• A similar security incident reportedly affected hundreds of French supermarkets last month.

Official Responses and Attribution

As of the latest updates, no group or individual has claimed responsibility for the attack, and the exact method of intrusion remains under investigation.

• Delhaize: Described the event to Belgian media as an overnight "computer incident" affecting 40 shops.
• Carrefour: Stated that it is currently analyzing the technical issues at its 15 affected Belgian stores.
• ICA: A spokesperson confirmed that a small number of stores operating outside ICA's central network were impacted and noted that corporate support is assisting with recovery efforts.
