France is seeking a European response after accusing an Iranian state-linked cyber unit of remotely disrupting refrigeration systems at hundreds of supermarkets — an allegation Tehran had not answered in the reporting.

Foreign Minister Jean-Noël Barrot described the October operation as an attack of “unprecedented scale and unprecedented aggression” and said those responsible would face Europe-wide sanctions. He said France had summoned Iran’s ambassador and characterised the incident as a major breach of national interests.¹

The scale described by French authorities was substantial: attackers allegedly altered digital thermostat settings at as many as 700 shops, driving some units from freezing temperatures to above 50C. Retailers reportedly discarded large quantities of food, while some sites suffered damage after overheating triggered safety systems.

Paris prosecutor Laure Beccuau said investigators had identified a modus operandi associated with Shahid Kaveh, a unit linked to the Islamic Revolutionary Guard Corps. The indicators cited included Farsi-language material and IP addresses traced to devices in Iran; her office opened an investigation into the unit’s leadership and others yet to be identified.²

The two accounts broadly agree that France is treating the incident as deliberate sabotage rather than a routine technical failure. They differ in emphasis over what is established publicly. The French government has not explained in detail how it reached its conclusion, and cyber attribution is inherently difficult because operators can conceal their location. Russian-aligned groups also claimed responsibility, though the reporting said those claims drew little credibility.

Later refrigeration disruptions in other European countries, as well as an attempted interference with French blood-product cold stores, have heightened concern. But reporting cautions that it remains unclear whether those episodes were connected to the French supermarket attack. EU foreign-policy chief Kaja Kallas said any Iran-attributed incidents in Europe would warrant a strong response, with the issue expected to be discussed by foreign ministers.
