Supermarket refrigeration and freezer systems across Europe have become the target of a sophisticated wave of cyberattacks, leading to significant food spoilage and hardware damage. The incidents, which involve hackers remotely gaining access to internet-linked cooling units to manipulate temperature settings, have affected more than 100 shops across several European countries, with reports of similar disruptions emerging from military bases in the United States.
The impact of these breaches has been severe for retailers. In Belgium, the butchery chain De Laet & Van Haver reported that temperatures in their refrigerators were forced as high as 18 degrees Celsius, resulting in the loss of meat products valued at approximately 15,000 euros. Other major retailers, including Dutch operator Delhaize, Carrefour, and the Colruyt group, have confirmed that various locations were hit by IT incidents, ranging from complete refrigeration shutdowns to partial operational failures. Similar disruptions were reported at Swedish retailer Coop and Irish wholesaler Musgrave’s SuperValu stores.
The pattern of the attacks appears to have expanded over recent months. In October, hundreds of supermarkets in France were targeted, resulting in tonnes of spoiled food and damage to refrigeration units, some of which reportedly melted or caught fire due to extreme heat. Professor Awais Rashid of the University of Bristol noted that hackers are exploiting vulnerabilities in refrigeration controllers that are improperly exposed to the internet. Many of these systems, often managed by third parties, rely on outdated software and frequently utilize easily guessable passwords, allowing unauthorized users to gain remote access to system configurations.
The scope of the disruption has reached as far as the United States, where military facilities have been targeted. In August, freezers at Fort Huachuca in Arizona were forced into a defrost mode, ruining their contents. A naval station in Newport, Rhode Island, also reported a refrigeration failure that left only dry goods available for purchase. Reuters reported that the Pentagon is investigating these malfunctions as suspected cyberattacks and is currently in communication with French authorities regarding the broader trend of international sabotage.
European officials have expressed growing concern regarding the motivation behind these persistent attacks. Christophe Hansen, the European Commissioner for Agriculture and Food, described the targeting of refrigeration systems as a deliberate effort to disrupt the bloc’s food supply chain and erode consumer confidence. While authorities currently maintain that overall food security is not at immediate risk, the financial and societal costs have been described as substantial.
Investigations into the source of the attacks are ongoing. Belgium’s prosecutor’s office confirmed it has launched a criminal investigation into the recent series of breaches. To date, no group or individual has claimed responsibility for the operations. While there has been public speculation regarding potential state-sponsored actors, experts like Professor Rashid emphasize that the primary objective appears to be systemic disruption rather than traditional cyber-crimes such as financial theft.
Looking ahead, the incidents highlight a critical weakness in modern retail infrastructure as stores increasingly rely on internet-connected management systems. The vulnerability of these appliances, many of which are past their intended end-of-life cycle, remains a significant concern for infrastructure security. As authorities continue to coordinate across borders, the focus remains on mitigating further damage to the food supply chain and securing remote-access protocols for commercial cooling equipment.
