Grocery retailers throughout Europe are grappling with a fresh wave of alleged cyberattacks, which have caused abrupt alterations in the temperatures of refrigeration units. Significant supermarket brands in Belgium, Sweden, Luxembourg, and Estonia have reported these incidents, according to various local news outlets.
An Ica Kvantum store in Sweden took to social media, indicating that cyber intruders had tampered with its refrigeration systems overnight, raising temperatures to 50 degrees Celsius (122 degrees Fahrenheit). A representative from the Swedish chain Coop confirmed to local media that “unauthorized individuals gained access to and manipulated the cooling systems at a small number of our locations.” Similarly, Dutch supermarket chain Ahold Delhaize stated that an “IT incident” led to temperature adjustments in refrigeration units across several supermarkets in Belgium and Luxembourg. The complete impact of these incidents is still being assessed.
Modern supermarket refrigeration units are often connected to the internet, enabling remote monitoring and maintenance alerts. However, the rise in these suspected cyber incidents has sparked concerns regarding the vulnerabilities within food supply chains. This current situation comes on the heels of a previous cyberattack that affected hundreds of refrigerators in French supermarkets last month, resulting in significant food spoilage estimated to cost millions of Euros. Additionally, there have been numerous reported malfunctions in freezer systems at US military bases, which are also thought to be linked to cyberattacks.
