A coordinated, suspected cyberattack has disrupted temperature control infrastructure across multiple major supermarket chains in Western and Northern Europe. Hackers specifically targeted commercial refrigeration and deep freezer units overnight, forcing store operators to throw out thousands of euros worth of perishable food stocks to maintain food hygiene and consumer safety.
Major Supermarket Outlets Struck in Belgium and Sweden
The disruption hit retail networks in Belgium and Sweden particularly hard. Delhaize, one of Belgium's premier grocery retailers, disclosed that an overnight computer incident crippled operations across roughly 40 of its supermarkets. French-owned supermarket giant Carrefour also reported disruptions, stating that it is actively analyzing the technical disruption across 15 of its Belgian locations.
In Sweden, multiple outlets belonging to retail brands ICA and Coop experienced similar operational failures. A representative for ICA confirmed that the incident primarily hit a limited collection of independent storefronts operating outside the group's central computer network. Corporate teams have stepped in to assist the impacted store managers in stabilizing systems and handling compromised stock.
Freezer Temperatures Forced to 50 Degrees Celsius
The attackers executed dramatic temperature overrides inside commercial cold storage units. At an ICA branch in Sjöbo, located in southern Sweden, store management discovered that automated controls for both refrigerators and freezers had been breached overnight. The hackers altered thermal parameters, forcing the freezers up to an extreme 50 C (122F).
Because frozen goods thawed rapidly under these elevated settings, the facility had to dispose of extensive inventory. The Sjöbo store temporarily closed its doors to clear damaged stock and reset environmental controls before resuming regular retail operations. Meanwhile, Coop confirmed that seven out of its 800 Swedish branches suffered system issues, noting that the overall crisis was rapidly contained and brought under operational control.
Disruptions Extend to Irish Retailers
The fallout from the technical incident also spread across international borders into Ireland. Retailer SuperValu saw 13 of its stores impacted by similar refrigeration failures. The multi-chain incident highlights growing operational risks facing automated facility controls and internet-connected industrial equipment across Europe's commercial food distribution landscape.
