A cyberattack affecting approximately 700 supermarkets in France has exposed serious weaknesses in the digital systems used to control commercial refrigeration, raising concerns about the vulnerability of European food distribution networks and other essential infrastructure.

The attack began overnight on 11–12th October, when intruders gained access to remotely managed refrigeration equipment and altered operating settings, causing refrigerators and freezers to overheat.

Stores belonging to several major supermarket chains were affected, including Intermarché, Netto, Coopérative U, Carrefour and Monoprix. Some were forced to discard substantial quantities of fresh and frozen food.

French Finance Minister Roland Lescure confirmed that approximately 700 of the country’s 10,000 supermarkets had been affected, although the severity of the disruption varied between locations.

The Paris prosecutor’s office has opened an investigation into the attack, including the damage caused by destroyed merchandise and reported fires.

The incident has drawn attention to industrial control systems that are routinely connected to the internet but may receive less cybersecurity protection than corporate networks and customer databases.

Refrigeration systems remotely manipulated

Investigators have established that refrigeration equipment was targeted through vulnerabilities associated with remote monitoring and control systems.

The French cybersecurity authorities identified compromises involving products supplied by Danish manufacturer Danfoss and American company Copeland.

Some of the affected systems used older equipment that no longer received regular security updates.

According to information released by the companies and cybersecurity specialists, certain industrial controllers had been accessible through public internet connections, creating opportunities for unauthorised access.

Hackers reportedly manipulated defrost cycles and increased temperature settings, preventing equipment from maintaining the cold conditions required to preserve food.

The attack affected approximately 300 Intermarché and Netto stores, while Coopérative U reported disruption at around 80 outlets.

Several retailers managed to contain the damage, but others lost substantial quantities of stock.

The consequences extended beyond malfunctioning equipment. Businesses faced the cost of replacing spoiled food, repairing refrigeration systems and restoring normal operations.

The precise financial damage is still being assessed, although estimates from the retail sector indicate that losses across France could amount to tens of millions of euros.

Vulnerabilities in connected equipment

The incident illustrates the security problems created by the growing use of internet-connected industrial equipment.

Modern refrigeration installations allow contractors and maintenance specialists to monitor temperatures, adjust settings and diagnose faults remotely.

These arrangements can reduce operating costs and improve efficiency, but they also create additional access points that attackers may exploit.

Cybersecurity specialists have identified vulnerabilities in commercial refrigeration platforms manufactured by Danfoss and Copeland.

The manufacturers subsequently addressed identified flaws, although older or unsupported equipment remained a concern.

A critical problem for businesses is that industrial machinery often remains operational for many years after its original software has become obsolete.

Replacing entire refrigeration installations can involve substantial expense and operational disruption, encouraging operators to retain equipment that may no longer meet contemporary cybersecurity standards.

The risks are particularly difficult to manage when responsibility for maintenance, software updates and network security is divided between retailers, equipment suppliers and external contractors.

France’s delayed cybersecurity legislation

The attack has renewed scrutiny of France’s implementation of the European Union’s NIS2 Directive, which is intended to strengthen cybersecurity across sectors providing important economic and public services.

The directive establishes common requirements covering risk management, incident reporting, organisational responsibility and protection against cyber threats.

Its scope extends beyond traditional critical infrastructure such as energy, telecommunications and transport to include certain businesses involved in food production, processing and distribution.

EU member states were required to incorporate the directive into national legislation by 17 October 2024.

France was among the countries that received a formal warning from the European Commission in May 2025 over incomplete implementation.

French cybersecurity specialists have since warned that delays have complicated efforts to establish consistent obligations for organisations operating industrial and commercial systems.

However, NIS2 does not automatically cover every supermarket. Its application depends on the nature and size of an organisation and the provisions of national implementing legislation.

The incident therefore raises questions not only about the pace of legislative implementation but also about the practical protection of equipment already in use.

Wider implications for European infrastructure

The disruption demonstrates how a cyberattack can cause physical damage without directly targeting a conventional industrial facility.

Unlike breaches intended to steal customer information, the French incident interfered with machinery responsible for preserving essential products.

The distinction is important for European policymakers, who increasingly face threats to infrastructure that combines digital controls with physical operations.

The European Union’s cybersecurity agency ENISA has organised cross-border exercises to test how authorities and companies would respond to disruption affecting essential services.

The attack itself has been established, but responsibility for it has not been publicly attributed.

French authorities have said there is no immediate threat to national food supplies. Nevertheless, the destruction of merchandise and interruption of ordinary retail operations have demonstrated the potential economic consequences of weaknesses in relatively commonplace equipment.

The continuing investigation must establish how access was obtained, which systems were compromised and whether the vulnerabilities were known to operators before the attack.

For Brussels and national regulators, the case provides a practical test of whether European cybersecurity legislation can translate into effective protection for the connected equipment on which ordinary commercial activities increasingly depend.

The United States has warned the European Union that proposed restrictions on American satellite operators could provoke commercial retaliation against European businesses, escalating a dispute over the future of satellite communications and Europe’s efforts to reduce its dependence on foreign technology.

US Ambassador to the EU Andrew Puzder has criticised plans under consideration in Brussels that would reserve parts of the radio spectrum for European operators, potentially restricting services provided by Elon Musk’s SpaceX and its Starlink satellite network.

According to details of Washington’s objections, the American administration believes the proposed arrangements would discriminate against US companies and undermine competition. Puzder has warned that European businesses could face substantial consequences if the restrictions proceed.

The disagreement comes as Brussels pursues a broader strategy intended to strengthen Europe’s technological independence in satellite communications, cloud computing and artificial intelligence. Washington has increasingly challenged European regulations that it considers detrimental to American technology companies.

A dispute over access to satellite frequencies

At the centre of the disagreement is the allocation of radio frequencies used by satellite communications systems. Access to suitable spectrum is essential for providing reliable services, particularly as operators deploy increasingly large constellations in low Earth orbit.

SpaceX has established a substantial commercial and technological advantage through Starlink, which operates thousands of satellites and provides broadband services to residential, commercial and government customers across numerous countries.

European operators argue that the expansion of American satellite networks could make it difficult for European competitors to secure sufficient spectrum and develop commercially viable services.

Washington takes a different position, warning that preferential treatment for European operators could restrict competition rather than strengthen it.

The precise legal form of the proposed EU restrictions, and whether they will proceed, remain unsettled. No final European prohibition on American satellite services has been announced.

Nevertheless, the dispute raises a question for Brussels: whether measures intended to protect European industrial capacity can be introduced without exposing European exporters and investors to American retaliation.

Europe’s satellite ambitions

The European Commission is investing heavily in IRIS², its secure satellite communications programme, which is intended to provide independent communications capabilities for governments, defence organisations and commercial customers.

Under arrangements confirmed in August, the programme’s principal constellation is planned to comprise 348 satellites operating in low and medium Earth orbit, with initial launches scheduled for 2029.

The system is designed to reduce Europe’s reliance on communications infrastructure controlled by companies or governments outside the EU, particularly during military emergencies, cyber incidents and interruptions to terrestrial networks.

The Commission’s technical programme envisages communications services supporting border management, crisis response, defence and other sensitive government activities.

However, IRIS² is not yet operational, and European commercial operators face significant competition from SpaceX.

Eutelsat, which operates the OneWeb satellite network, is among the European companies positioned to benefit from increased demand for alternatives to Starlink.

Its shares rose sharply on 14 October following reports of restrictions affecting Ukrainian access to certain Starlink services. The market reaction reflected renewed interest in European-controlled satellite communications.

OneWeb cannot simply replace Starlink across all applications. Differences in network architecture, terminal equipment and available capacity complicate any rapid transition.

Ukraine adds a security dimension

The dispute is particularly sensitive because Starlink has become an important part of Ukraine’s communications infrastructure during Russia’s invasion.

Ukrainian forces have relied on satellite connectivity for communications in areas where conventional telecommunications infrastructure has been damaged or destroyed.

The strategic consequences of relying on a commercial provider became more prominent following reports that access to certain Starlink capabilities had been restricted.

For European governments, the episode has reinforced concerns about whether defence communications should depend on technology controlled by a company subject to political and commercial pressures outside Europe.

Yet restricting American participation before European alternatives are fully available could produce its own operational difficulties.

The Commission must therefore distinguish between developing independent European capabilities and limiting access to services that governments, businesses and military organisations currently require.

Another transatlantic regulatory confrontation

The satellite dispute follows disagreements over European regulation of American digital companies, including competition enforcement and restrictions on online platforms.

As EU Today reported in May, the European Commission had already proposed reserving much of the future mobile satellite spectrum for European operators.

Washington’s opposition introduces a different dimension because spectrum allocation affects market access directly.

The American administration is also linking the dispute to broader commercial relations, raising the possibility that measures affecting satellite companies could produce consequences for unrelated European industries.

Brussels has not announced a final decision on the disputed spectrum arrangements, while the United States has not specified which retaliatory measures it would impose.

The immediate issue is therefore regulatory rather than an enacted trade restriction. Whether it develops into a wider confrontation will depend on the Commission’s final proposals and Washington’s willingness to pursue its warning through commercial measures.
