A wave of cyberattacks targeting supermarket refrigeration systems has disrupted operations across multiple European countries, including Sweden, the Netherlands, Belgium, Ireland, Luxembourg, and Estonia. These attacks resulted in significant temperature fluctuations that spoiled food products, raising concerns about food safety and security in the region.
The incidents follow a previous attack in France where hackers gained control of cooling units in hundreds of supermarkets, causing temperatures to soar to dangerous levels, resulting in food spoilage and fires. As of now, authorities have not identified the perpetrators behind these latest attacks, and no groups have claimed responsibility.
The European Commission emphasized that these incidents underscore the growing threat of digital attacks impacting everyday life. Reports indicate that several supermarkets, including those in the ICA chain in Sweden, were affected, with some stores having their fridges hacked and set to temperatures as high as 122 degrees Fahrenheit.
In Belgium, a spokesperson for Colruyt Group confirmed that five of their stores were compromised, while Carrefour reported limited effects on 15 of their outlets. In Ireland, the wholesaler Musgrave noted that 13 SuperValu stores had to remove chilled items from sale due to a cyber incident.
Cybersecurity experts warn that the increasing connectivity of devices ranging from refrigeration systems to security cameras has opened new avenues for cybercriminals. In Sweden, the national cybersecurity center is actively investigating multiple incidents affecting grocery stores, highlighting a critical need for improved security measures within the industry.
As the situation develops, the focus remains on restoring operations and preventing further attacks, with companies urging immediate action to secure their systems against potential vulnerabilities.
