Cyberattacks Disrupt Supermarket Refrigeration Systems Across Five EU Countries

The incidents affected the equipment used to store perishable goods and exposed the final stage of the food supply chain to disruption. Supermarket chains Ahold Delhaize and Colruyt reported attacks affecting critical refrigeration systems in Belgium and Luxembourg, the report stated ^[1][3].

Retailers threw away food that had warmed above safe holding temperatures, according to the report ^[2]. The hacking attack on European supermarkets hit fridges and freezers from Sweden to Belgium and forced stores to discard, the report stated ^[1].

Retailers Report Store-Level Impact

Carrefour said 15 Belgian stores were affected, while Irish wholesaler Musgrave said refrigeration systems at 13 SuperValu locations were impacted, according to Reuters ^[1][4]. Musgrave said it had to remove some chilled and frozen products from sale, the report stated ^[4].

Defrost cycles are routine maintenance functions, but sustained operation at high temperatures spoils chilled and frozen stock. The incidents affected refrigeration equipment used to store perishable goods, a segment of the food supply chain that retailers said required urgent attention.

Prior Attack in France Cited

The cyber incidents followed an attack in France last month in which hackers seized control of cooling units at hundreds of supermarkets, causing high food losses, according to the report ^[1][5]. French supermarkets reported temperatures forced as high as 50 C, with food losses described as worth millions of euros ^[5].

Reuters reported that the similarities between the incidents suggested the earlier attack may have served as a pilot run for broader disruptions ^[2]. Coverage of the French episode questioned the "sophisticated-hacker" framing of the event while confirming the temperature spikes and the scale of the losses ^[5].

Targeting refrigeration systems at supermarkets can quickly destroy perishable foods and disrupt food availability, the report stated ^[1]. Security analysts note that attribution in cyber operations is difficult because attackers route traffic through tunnels, virtual private networks and compromised machines, complicating efforts to identify who is responsible ^[6].

Advisories on Food Stockpiling Preceded Incidents

The cyberattacks came weeks after governments in Europe, the U.S. and Australia urged households to maintain emergency food supplies, according to the report ^[2]. The advisories did not identify a specific imminent threat, the report stated ^[2].

The European Union has shifted toward what one leaked document described as "war economy mode," stockpiling critical minerals, food, medicines and nuclear fuel amid rising geopolitical threats and supply chain fears ^[7]. That posture reflects preparations for war, cyberattacks and supply chain collapses, according to reporting on the document ^[7].

Investigations and Official Response

The European Union warned of a deliberate attempt to disrupt the food supply chain, the BBC reported, as problems were reported in at least nine countries ^[8]. The pattern of disruption against food infrastructure is not new, however. The U.S. Federal Bureau of Investigation's Cyber Division previously warned that food processing plants were likely to face cyberattacks ^[9].

Analysts have warned that cyberwar could involve hacking anything that runs on the internet or computers, from power grids to pipelines and bank systems ^[10]. Practical preparation guidance has long advised that attacks on computer systems could shut down electrical, gas, communications, transportation and emergency services, and that attacks on farms and processing plants would completely shut down food production and distribution systems ^[11].
