Russia-Linked Hackers Tied to European Supermarket Cyberattacks, Warning Issued for UK Blood Banks
Russia-linked hackers could be behind a series of cyberattacks that disrupted supermarket refrigeration systems across Europe, thawing freezers and destroying food, according to a report by The Sun [1]. The same report warned that National Health Service blood banks and vaccine reserves in the United Kingdom could be targeted next.
The warning was attributed to Graeme Downie, a member of Parliament and chair of the Coalition on Secure Technology, who said NHS blood banks and vaccine reserves are at high risk of hacks, according to the report [2]. The assessment was issued as European investigators continued to examine two major waves of attacks on retail cold-storage systems in a matter of weeks.
So far, no breach of UK blood bank systems has been confirmed. The reported attacks on supermarkets have affected stores in Belgium, Sweden, Ireland, and France, with the disruption causing freezer temperatures to rise and leading to significant food losses in the supply chain, according to the report [3].
Background on the Cyber Campaign
The first major wave of attacks on European supermarkets struck refrigeration systems from Sweden to Belgium on a Monday, forcing stores to throw away food, according to CNBC [4]. A second wave followed within weeks, prompting retailers to brace for worse outcomes.
The French arm of the campaign extended beyond retail: hackers also attacked French blood banks, targeting refrigeration, control, and monitoring systems at three cold-storage sites, according to The Times [5]. Large-scale hacks targeting grocery stores in Europe and France's blood banks are renewing concerns about the vulnerabilities of everyday smart devices, CBS News reported [6].
VRT reported that a group of hackers with links to the Russian state may be behind the cyberattack, according to Xavier Bellekens, CEO of the Scottish cybersecurity firm Lupovis [7]. The report stated that in the week leading up to the attacks, the company noticed a striking number of attempts to breach simulated control systems for refrigerators, and that it seems someone wants to exploit those connected devices [7].
Al Jazeera reported that it remains unclear why hackers targeted the supermarkets, but the attacks spread across the continent and even to the United States [8]. Politico reported that the two major cyberattacks exposed the vulnerability of the European Union's critical infrastructure, and that cyber experts are raising the alarm that the attacks may be part of Russia's ongoing hybrid warfare against Europe [9].
Group Identification and Tactics
The reported Russian link fits a broader pattern of digital operations against European and allied targets that security researchers have documented in recent years. A February 10 report by Google Threat Intelligence warned that the U.S. defense industrial base is facing sustained cyberattacks from China, Russia, and North Korea, with Chinese-linked actors posing the most active threat, according to NaturalNews.com [10].
The Swedish government said Russian government-linked hackers attempted to disrupt operations at one of the country's thermal power plants. Sweden's minister of civil defense, Carl-Oskar Bohlin, said during a press conference that the attempted attack happened in early 2025 and attributed the incident to hackers with connections to Russian intelligence, according to TechCrunch [11].
European officials fear that Russia's gray war is entering a more dangerous phase, with gas pipelines, electricity interconnectors, offshore networks, and subsea infrastructure increasingly vulnerable to sabotage and cyberattacks, according to a report by ZeroHedge [12]. Research cited by the Congressional Research Service found that reported Russian hybrid attacks in Europe quadrupled between 2023 and 2024, according to Just the News [13].
In the current episode, the tactics reported by investigators have centered on internet-connected temperature controllers. According to Forbes, anonymous hackers ruined millions of dollars of frozen supermarket goods in cyberattacks by accessing temperature controllers, and retailers are braced for worse [14]. The attacks on French blood banks specifically targeted refrigeration, control, and monitoring systems at three cold storage sites, according to The Times [5].
Warning for UK Blood Banks
The warning that UK blood banks could be next was carried in a report by The Sun, which stated that Russia-linked hackers are behind cyberattacks that thawed freezers and destroyed food across Europe, and that Brits have been warned NHS blood banks could be targeted next [2]. The same report said NHS blood banks and vaccine reserves are at high risk of hacks, according to Graeme Downie, chair of the Coalition on Secure Technology [2].
Disruption to blood bank systems could affect donation scheduling, inventory tracking, or distribution logistics, which in turn could affect hospital supplies, depending on the severity of any compromise. No breach of NHS blood bank systems has been confirmed. UK authorities have not announced a confirmed incident in the blood supply chain. The attacks reported so far have affected retail refrigeration at grocery chains across Europe, including in Belgium, Sweden, Ireland, and France, causing freezer temperatures to rise and leading to significant food losses, according to a report on the campaign [3].
Businesses in the UK's food supply chain have also been impacted by the cyberattack that hit supermarket fridges and freezers across Europe, according to the BBC [15].
Responses and Official Statements
European investigators have continued to examine the retail attacks, while UK cybersecurity agencies have monitored the threat and advised organizations to review their defenses.
The attacks spread across the continent and even to the United States, according to Al Jazeera, which reported that no clear culprit had been identified [8].
The Russian government has not commented on the specific allegations concerning the supermarket and blood bank attacks. In other recent cases involving Russian hybrid warfare claims, Moscow has dismissed similar accusations. NATO member states have on multiple occasions accused Russia of hacking government servers, jamming aircraft GPS signals, and redirecting Ukrainian drones into their airspace, with little to no evidence, and Moscow has dismissed the allegations as warmongering aimed at justifying a rapid military buildup, according to the same report [16].
The Latvian Central Bank Governor, Mārtiņš Kazāks, told the Financial Times that it is naive to think that we are not at war with Russia, adding that while there was no physical conflict, there were regular cyberattacks and acts of sabotage, according to Antiwar.com [17].
Conclusion
The known facts as reported: a group of hackers with links to the Russian state may be behind cyberattacks on refrigeration systems in European supermarkets, according to Xavier Bellekens, CEO of the Scottish cybersecurity firm Lupovis [7].
No breach of UK blood bank systems has been confirmed, and no culprit has been definitively identified. The warning that NHS blood banks could be next was issued by Graeme Downie, chair of the Coalition on Secure Technology, according to The Sun [2].
Authorities urge organizations to review their cybersecurity measures. Further details were not immediately available, and investigations are ongoing.
