Cyberattack Heats French Supermarket Refrigerators

A cyberattack on French supermarkets has raised concerns about whether Australian retailers could face similar disruption. Hackers reportedly altered the temperature settings of refrigeration systems in hundreds of stores, causing frozen and chilled food to spoil. Intermarche owner Les Mousquetaires said refrigerators in about 150 stores were heated to 50 degrees Celsius for six hours overnight. Reports said at least 300 Intermarche or Netto stores, more than 100 Cooperative U outlets, several E Leclerc stores, 80 Carrefour Market stores and 5 per cent of Monoprix stores were affected. Intermarche’s chief executive estimated nationwide losses could reach tens of millions of euros. French authorities are investigating. A source close to the French prime minister said France’s National Cybersecurity Agency identified a vulnerability in software made by Danish company Danfoss. Danfoss said some affected refrigeration controllers used outdated firmware and reiterated its advice to update supported systems and replace legacy equipment. Security research published in August had described vulnerabilities in a Danfoss controller that software updates addressed. The precise attack method remains unconfirmed; experts say it could have involved known but unpatched software flaws, a previously unknown “zero-day” vulnerability, compromised credentials, insecure remote access, or weaknesses in a third-party or centralised management platform. Australian experts say similar attacks are possible if retailers use comparable systems. A compromised corporate network or refrigeration-management platform could let attackers alter settings across many locations, with consequences including food waste, store closures, inventory losses, supply-chain disruption and reputational damage. Large chains such as Woolworths, Coles and Aldi may be attractive targets because their systems are centralised, though experts caution that being a target does not necessarily mean being vulnerable: large companies may have greater cybersecurity resources, while smaller retailers may have fewer. The article also warns that internet-connected operational technology is increasingly used to run essential physical infrastructure. Aging equipment and outdated software can leave systems exposed, while advances in AI may give criminals additional ways to search for vulnerabilities.

The article reports that a cyberattack targeting refrigeration systems at supermarkets in France caused serious disruption and financial damage. According to the supplied text, hackers remotely raised the temperature of affected systems to 50 degrees Celsius. The temperature increase reportedly triggered fires, while the failure of refrigeration left shelves empty and led hundreds of stores to discard food. The headline characterizes the resulting losses as amounting to millions, although the excerpt does not specify a precise total, identify the affected supermarket chains, or explain how the attackers gained access. The reported consequences include both immediate physical hazards and broader disruption to food retail: fires, spoiled or discarded stock, and empty shelves across France. The excerpt does not provide details about injuries, the duration of the incident, the number of locations affected beyond saying hundreds of stores, or the status of any investigation or response. It also does not name the hackers or describe whether the attack was directed at a particular company or carried out against multiple operators. The article’s presentation is brief and news-oriented. Its central focus is the reported connection between remote interference with supermarket refrigeration and the resulting fires and losses. Because the provided content is only a short newsfeed description, further context and verification details are not available in the text supplied.

A cyberattack affected more than 500 French supermarkets, remotely raising temperatures in internet-connected refrigerators and freezers to as high as 50°C while stores were closed. The resulting damage spoiled millions of euros’ worth of food, and in some locations reportedly caused fires or melted equipment. Major chains affected included E-Leclerc, Intermarché, Carrefour, Monoprix and Coopérative U; the reported scale ranged from at least 300 Intermarché and Netto stores to more than 100 Coopérative U supermarkets, 80 Carrefour stores and about five percent of Monoprix’s roughly 490 shops. France’s cybersecurity agency advised operators of the affected freezer models to disconnect them from the internet or restrict access and install software updates. Investigators have not identified those responsible or fully explained how the attack was carried out. French broadcaster BFM reported that attackers may have activated a forced-defrost function. The targeted systems were manufactured by Danish company Danfoss, which said many were legacy products running outdated firmware and that it had previously recommended updates. French officials are also consulting other European countries about possible impacts. The article places the incident in the context of earlier cyberattacks on food retailers and suppliers. It cites the 2025 ransomware attack on British retailer Marks & Spencer, which disrupted online and app orders and reportedly cost about £300 million, as well as attacks affecting United Natural Foods and Ahold Delhaize USA. Analysts say supermarkets are vulnerable because food and agricultural operations increasingly depend on connected technology, while perishable stock and interconnected supply chains can make disruptions costly and far-reaching. Cybersecurity analyst Steven Lachance warns that internet-connected equipment can be exploited and says the incident should prompt national and international measures to protect critical infrastructure. The article also notes President Emmanuel Macron’s recent call to protect France’s critical infrastructure from Russian “hybrid attacks,” without attributing this supermarket attack to Russia.

A cyberattack on internet-connected refrigeration systems affected hundreds of supermarkets in France, raising temperatures in fridges and freezers to as high as 50°C and spoiling fresh and frozen food. Fires were also reported at several stores. Intermarche and its Netto brand said at least 300 shops were targeted; Cooperative U reported more than 100 affected outlets, Carrefour said 80 supermarkets were hit, and Monoprix reported disruption at about 5 percent of its roughly 490 stores. E Leclerc also said several locations were targeted. French authorities treated the incident as a large-scale attack on connected refrigeration equipment. Prime Minister Sebastien Lecornu asked the National Cybersecurity Agency (ANSSI) to investigate. France was coordinating with European counterparts and assessing whether other companies might be vulnerable. Intermarche CEO Thierry Cotillard estimated the losses could reach tens of millions of euros nationwide in a single day. Affected stores had to discard fresh and frozen products, while retailers worked to restore normal operations. The article reports that ANSSI identified a vulnerability in software supplied by Danish company Danfoss. Danfoss said affected units were running outdated firmware and reiterated its advice that customers update systems and replace older equipment. The incident followed cybersecurity research published by Claroty in August describing vulnerabilities that could allow authentication to be bypassed in Danfoss systems. A Sekoia analyst told Reuters that Spain, Portugal, Poland, Germany and Belgium had also been affected. Cybersecurity analyst Steven Lachance said the scale was rare, even if attacks on connected equipment were not unprecedented. He characterized the incident as a warning about internet-connected infrastructure and called for national and international preventive measures. He cautioned that future attacks could target more consequential systems, including energy infrastructure or hospitals.

A cyberattack disrupted refrigeration systems at hundreds of French supermarkets, causing some fridges and freezers to heat to as much as 50°C (122°F) overnight. The affected chains included Carrefour, Monoprix, Intermarché and Coopérative U. The incident spoiled fresh and frozen food and, according to the article’s key points, sparked fires; however, a Les Mousquetaires spokesperson said that some stores experienced smoke but that no fires had been reported. Coopérative U CEO Dominique Schelcher condemned the attack as unprecedented and said it targeted equipment vital to food preservation and the national food supply. The Les Mousquetaires group, which owns Intermarché and Netto, said around 180 stores were affected and estimated losses could reach several million euros. It attributed the disruption to an attack on a service provider that manages refrigeration systems at some stores. The chains removed and disposed of potentially affected products as a consumer-safety precaution. The group said it was awaiting assessments by a court-appointed bailiff and insurance experts to establish the damage more precisely. Sekoia analyst Felix Aime told Reuters the attack affected several European countries, including Spain, Portugal, Poland, Germany and Belgium. European Commissioner for Agriculture and Food Christophe Hansen condemned the targeting of food products and warned that the weaponization of food had become a reality. Separately, supermarket group Ahold Delhaize reported a security issue within its network and took systems offline, though its stores remained open. The article places the incident within a wider rise in cybercrime, noting concerns that artificial intelligence can increase the scale and speed of attacks. It cites a recent data breach at British retailer Asos, a cyberattack that temporarily shut down a small U.K. power plant, and comments by Interpol security chief Bjorn R. Watne that AI can help attackers target multiple victims at once. Watne characterized AI’s role as an evolution rather than a revolution.

The France 24 video report says major French supermarket chains were hit by a cyberattack that caused refrigeration temperatures to rise in hundreds of stores. The resulting loss of cooling led to food spoilage and required stores to discard affected products. The report frames the incident as more than an operational disruption: the scale of the affected stores and the quantity of food at risk raised concerns about food security. The supplied article text is very brief and does not identify the supermarket chains, explain how the attackers gained access, specify the precise number of stores or amount of food affected, or describe the response by authorities or the companies. Its headline says the hackers heated supermarket fridges and that this sparked fires, but the available body text does not provide details about fires. The only further information in the report’s body is that the chains said the attack occurred on Monday. The video is credited to Reuters and France 24 and is listed as a 1-minute, 17-second item, issued on October 13, 2026. Overall, the report presents a cyberattack with tangible consequences for retailers and consumers: disrupted refrigeration, spoiled food, and heightened concern over the security of the food supply.
