Dutch-Belgian supermarket group Ahold Delhaize has confirmed that malicious activity was responsible for the cybersecurity incident that disrupted its operations across Europe and the United States, forcing the company to take websites, applications and other computer systems offline.

In an official statement issued on Monday, 19 October, the company announced that it had filed a formal complaint with Dutch police and was cooperating with national cybersecurity authorities. Although physical supermarkets have remained open, the disruption has affected online shopping, deliveries and some distribution operations.

The company said investigators had so far found no evidence that sensitive information belonging to customers, employees or business partners had been taken. However, its investigation remains open, and the identity and objectives of those responsible have not been publicly established.

Online services interrupted across several countries

The disruption began on 12 October, when Ahold Delhaize detected suspicious activity within its information technology infrastructure.

The group responded by taking a number of systems offline as a precaution, affecting most of its retail brands in Europe and the United States. The consequences varied considerably between businesses, with some experiencing prolonged interruption to digital services while others were able to restore operations more quickly.

Albert Heijn, the Netherlands’ largest supermarket chain, has been particularly affected. Its website and mobile application have returned online, but home grocery deliveries are not expected to resume until Friday, 23 October.

Orders scheduled before that date have been cancelled, while the company continues preparations for a gradual restoration of its online delivery service.

The incident also interrupted some supply and distribution arrangements, resulting in shortages on supermarket shelves in parts of the Netherlands and Belgium.

In Belgium, Delhaize has restored its online shopping operations. Certain promotional and personalised services were still experiencing difficulties, although the parent company confirmed that its Belgian e-commerce business was operational again.

Dutch retailers Etos and Gall & Gall have also restored their websites. Meanwhile, several American supermarket brands owned by Ahold Delhaize have continued to experience service interruptions.

The group said it expected additional online services in the United States to become available over the coming days.

Dutch authorities investigate

Ahold Delhaize said it notified the Netherlands’ National Cyber Security Centre within 24 hours of detecting the malicious activity.

The company has subsequently provided updates to the authorities and, on Monday, confirmed that a formal police report had been submitted.

Chief executive Frans Muller defended the decision to shut down digital systems, arguing that the investigation had demonstrated the necessity of taking preventive action.

The company has not identified the perpetrators, confirmed whether ransomware was involved or disclosed the technical method used to gain access to its infrastructure.

These distinctions are important because malicious activity does not necessarily establish that information was stolen or that attackers obtained control over every system subsequently taken offline.

The retailer has instead described a controlled restoration process intended to ensure that affected systems can be brought back into operation without exposing the business to further risks.

Ahold Delhaize operates thousands of supermarkets and related retail businesses, including Albert Heijn, Delhaize, Food Lion, Giant Food, Hannaford and Stop & Shop.

Its geographical reach means that a disruption originating within shared corporate infrastructure can affect several national markets, even where individual retail chains maintain separate commercial operations.

Cybersecurity becomes a supply-chain concern

The attack comes amid increasing scrutiny of the vulnerability of European food retailers to digital disruption.

Earlier this month, investigators in France began examining cyberattacks against refrigeration control systems used by hundreds of supermarkets.

Those incidents reportedly affected equipment at chains including Carrefour, Intermarché and Monoprix, with some retailers forced to discard products after refrigeration systems malfunctioned.

There is no established connection between the French incidents and the attack affecting Ahold Delhaize.

Nevertheless, both episodes illustrate the dependence of modern retail operations on interconnected digital systems supporting stock management, refrigeration, logistics, payments and customer services.

The consequences of a serious cyber incident can extend beyond the loss of access to websites. Interruptions to inventory systems, warehouse operations or communications with suppliers can affect the availability of physical products.

This creates particular difficulties for food retailers, where delays in transport and storage can result in the loss of perishable goods.

European regulatory implications

The incident also draws attention to the European Union’s NIS2 cybersecurity framework, which establishes stricter risk-management and incident-reporting obligations for organisations operating in designated sectors.

Food production, processing and distribution are among the activities covered by the directive, although its application to particular companies and operations depends on the relevant legal definitions and national implementing arrangements.

The legislation requires organisations within its scope to establish appropriate cybersecurity protections, address supply-chain risks and notify competent authorities of significant incidents.

Separately, the General Data Protection Regulation establishes notification requirements where personal-data breaches meet the relevant reporting threshold.

Ahold Delhaize’s statement that it has found no evidence of sensitive data being taken does not conclude the technical investigation, but it means that a confirmed theft of personal information should not presently be presented as a fact.

For the company, the immediate challenge remains restoring online services while maintaining normal supermarket operations. The wider commercial consequences, including the cost of the interruption and its effect on sales, have not yet been quantified publicly.

At least 550,000 households lost power overnight, Zelensky said, following a coordination meeting on the situation in Ukraine's regions.

The drone struck the town's central park while many people, including families with children, were there, Interior Minister Ivan Vyhivskyi said. An infant in a stroller and two women were among those killed, he added.

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.

On the night of Oct. 2, Russian drones struck Kyiv's Southern Bridge once again. The city closed it and Paton Bridge, restricted traffic on Metro Bridge, and was gridlocked by multi-kilometer traffic jams by morning.

In the Oct. 19 attack on Kyiv, at least one person was killed, and eight others were injured as Russian missiles struck Kyiv in multiple waves overnight.

President Volodymyr Zelensky said Russian forces targeted energy facilities in 11 oblasts across Ukraine.

The overnight assault also damaged a data center in Kyiv and infrastructure in Volyn Region, where around 66,000 electricity metering points were left without power, regional officials said.

Several explosions rocked the capital just before 11 p.m., with further attacks around 3 a.m. and 7 a.m., Kyiv Independent journalists on the ground reported. Ukraine's State Emergency Service (DSNS) said damage was reported in at least three districts.

Russian strikes hit 20 locations, while falling debris was reported at four other sites.

St. Petersburg Governor Alexander Beglov confirmed the attack, reporting fires at the St. Petersburg Oil Terminal, the Ruchyi oil depot, and industrial warehouses in the Kolpinsky District.

The Lutsk facility in northwestern Ukraine, which manufactures wiring systems for BMW, Audi, Mercedes-Benz, Porsche, and Skoda vehicles, was attacked by Russian drones on Oct. 16.

A lunchtime drone attack on the head office of Ukraine's National Academy of Sciences in Kyiv's downtown on Sept. 28, 2026, might have come as a shock to scientists based outside the country.

Unfortunately, for Ukrainian scientists, those who can be seen climbing down the ladders

According to monitoring channels ExileNova+ and SuperNova+, Russian technology giant Yandex's data center in Vladimir Oblast, around 500 kilometers (310 miles) from the Ukrainian border, was targeted in the overnight operation.

The Russian drone crashed near a 5-story residential building, damaging the facades of nearby buildings, as well as setting a car on fire.

Debris from a Russian drone damaged Cosmogony, a painting that set a national record in Ukraine, the Korsaks Museum of Contemporary Ukrainian Art in Lutsk, where the artwork was exhibited, reported on 14 October. A fire destroyed part of the painting’s final section, titled The Future, according to the statement.

Russian drones continue to attack Ukraine. Overnight into 15 October alone, Ukrainian air defense forces downed or suppressed 536 Russian unmanned aerial vehicles (UAVs). In recent days, Lutsk, a city in northwestern Ukraine, has been among the cities damaged by Russian attacks. Russian UAV attacks set fire to an oil depot, a wholesale warehouse, and a shopping center. At the museum, located on the shopping center’s premises, the fire damaged Ukraine’s largest painting, which covers a canvas of more than 2,000 square meters.

Russian attack damages museum in Lutsk

A fire broke out at the Adrenalin City shopping and entertainment complex, where the museum is located, Suspilne Lutsk reported. The blaze damaged the last of the painting’s six sections, according to the report.

“By destroying art and culture, they are also trying to destroy Ukrainians,” Tetiana Repnytska, director of the Museum of Contemporary Ukrainian Art in Lutsk, told Suspilne Lutsk.

Museum staff also had to evacuate more than 300 works by Ukrainian artist Emma Andiievska, which were exhibited alongside Cosmogony, Oles Tomakh, the museum’s chief curator, told Suspilne Lutsk. Some works could not be removed in time, resulting in shattered glass. However, the museum’s other exhibition halls were unaffected, the chief curator said.

The museum is weighing whether to fully restore the damaged fragment or keep the fire’s traces as a reminder of the war, and will decide after consulting the artist, Petro Antyp, and restoration specialists, it said. Repnytska told Suspilne Lutsk that the painting’s authors could also create a new section.

“Despite the shelling, we will continue to develop contemporary Ukrainian art and preserve it,” the museum director said.

Cosmogony—Ukraine’s largest painting

Artist Petro Antyp began working on the painting in November 2022, Suspilne Lutsk reported, and it took almost two years to complete, according to the museum’s website. The painting covers an area of 2,086 square meters.

In September 2024, the project set a national record as Ukraine’s largest painting.

The artwork explores the evolution of the universe, Earth, nature, humanity, society, culture, and science. Its six sections combine myths, legends, scientific theories, and symbols from different cultures, according to the museum’s website.

The project extends beyond the canvas, as the museum presents a multimedia performance that combines light, sound, and art.

Civilians killed and injured in Russia’s latest attack on Lutsk

Around noon on 14 October, a Russian jet-powered Shahed drone attacked Lutsk. Drone debris damaged a wholesale goods warehouse and a residential building, Roman Romaniuk, acting head of the Volyn Regional Military Administration, told Suspilne.

Falling drone debris sparked a large fire at the Yevrohurt wholesale warehouse. A nine-story residential building on Sobornosti Avenue was also damaged, Romaniuk later reported on social media.

Six people were killed in the strike on the warehouse: five were found at the scene, and another person died in the hospital. Eleven more people were injured, Romaniuk said.

Two other people, including a child, were injured in the residential building. Twelve people remained hospitalized, one of whom was in serious condition, according to the report.

The city and surrounding region were targeted in an "intense" Russian attack that began late on Oct. 14, Governor Andrii Raikovych reported. The strike targeted local logistics, transportation, and industrial enterprises.
