Impact of Cyberattack on European Supermarkets

A recent cyberattack has wreaked havoc on dozens of supermarkets across seven European countries, compromising their refrigeration and freezing units. This incident has raised significant alarm about the vulnerabilities faced by supermarkets in an increasingly digital world.

Widespread Effects Across Europe

Approximately 40 Delhaize supermarkets located in Belgium and Luxembourg were severely impacted. Additionally, a smaller number of stores in Sweden, Ireland, the Netherlands, Estonia, and Finland also experienced repercussions. Sabcobel, the Belgian company responsible for manufacturing affected refrigerator units, reported that the evaporators of the units were forced into defrost mode, leading to overheating. This method mirrors a similar attack that recently targeted hundreds of French supermarkets.

Significant Food Loss

Local media highlighted that millions of euros’ worth of food had to be discarded due to these failures. Stephan Moelans, CEO of Sabcobel, confirmed to the Belgian News Agency that this incident was indeed a cyberattack. He stated that their team had been dedicated to disconnecting the affected units from the network throughout the night and morning.

Responses and Measures Taken

Since the attack in France early last month, Sabcobel had been proactive in strategizing to bolster the security of their clients’ refrigeration systems. Moelans explained that while the company had made updates to the software, physical modifications to the refrigeration units were also necessary. “The simplest solution is to manage refrigerators through a secure network connection,” he noted. Most clients opted for this safety measure following the previous incident in France.

Temperature Rises and Security Monitoring

During this latest attack, many supermarkets reported that their freezer temperatures soared to alarming levels of up to 50°C. The national cybersecurity agencies of Belgium and Sweden are closely monitoring the situation, while the UK’s National Cybersecurity Centre is collaborating with international partners to thoroughly investigate the incident. Notably, there have been no similar occurrences reported in the UK.

Economic Impacts on Supermarkets

In Flanders, northern Belgium, a Delhaize branch in Hoeilaart revealed an estimated loss of €100,000 (about $112,145) in products due to the attack. This figure does not account for additional losses incurred from the store’s closure. Similarly, Carrefour, a French supermarket chain, reported that only 15 of its stores in Belgium were affected, and swift measures were implemented to keep remaining stores operational.

Additional Supermarkets Affected

In Sweden, several ICA and Coop stores were also touched by the attack. An ICA spokesperson confirmed that a limited number of stores operating outside the main network were impacted. One such store in Sjöbo took to social media to announce that their refrigeration units had been hacked, adjusting the temperature to an unsuitable level. Fortunately, this store has since reopened.

Seven branches of Coop in Sweden reported similar problems, though the company stated that the situation is now managed and under control. In Finland, several K supermarkets experienced refrigeration failures, with the chain’s security experts investigating the issue. Reports also indicated that supermarkets faced disruptions in Ireland, the Netherlands, and Estonia, further illustrating the widespread nature of this attack.

Conclusion

This recent wave of cyberattacks on supermarkets underscores the vulnerabilities present in modern retail environments. As many stores now rely heavily on internet-connected systems for refrigeration, securing these connections has become more crucial than ever. Supermarkets need to remain vigilant and invest in robust security measures to safeguard against future cyber threats.
