France has summoned Iran’s ambassador after accusing Tehran of being behind a cyberattack that disrupted refrigeration systems in hundreds of supermarkets. The French government described the incident as a serious threat to national security and warned that it could take further action if similar attacks continue.
Foreign Minister Jean-Noël Barrot said the attack targeted supermarket refrigeration systems in early October. The disruption affected hundreds of stores and created serious problems for businesses that depend on reliable cooling systems to protect food and other temperature-sensitive products. The government considers the incident one of the most disruptive cyberattacks against French infrastructure since the war involving Iran began in February.
French officials believe Iran’s Revolutionary Guards were responsible for the operation. Tehran has not publicly accepted responsibility, and Iran’s mission to the United Nations did not respond to requests for comment. The Iranian government has regularly rejected accusations that it carries out malicious cyber operations against other countries.
Barrot said France would seek European Union sanctions in response to the incident. He also warned that Paris could consider additional measures, including cyber operations, if they were judged necessary and proportionate. The minister did not explain what those possible measures might involve, leaving the government with room to decide how to respond.
The dispute comes at a difficult time for relations between France and Iran. The two countries have disagreed over Iran’s nuclear and missile programmes, its regional activities and the detention of French nationals. Tensions increased further after Iran arrested and expelled two French diplomats during the summer. France responded by expelling Iranian diplomats.
The supermarket incident also highlights how cyberattacks can affect ordinary services without directly targeting government offices or military systems. Refrigeration is essential to the food supply chain, and a major disruption can force stores to protect or dispose of products, change their operations and deal with financial losses. Such attacks can therefore create consequences for businesses and consumers far beyond the digital systems that are initially affected.
France has been among the European countries calling for stronger protection of critical infrastructure. Governments across the region are increasingly concerned about cyber operations targeting transport, energy, communications and commercial services. The growing use of connected systems has made these services more efficient, but it has also created new points of vulnerability.
The French government now faces the challenge of responding firmly while avoiding an uncontrolled escalation with Tehran. Any European sanctions would also require coordination with other EU members. The incident is likely to add to discussions about cyber defence, international responsibility and the protection of essential services.
For now, France has made clear that it considers the attack unacceptable and wants those responsible to face consequences. The diplomatic response and any further measures will depend on the government’s assessment of the evidence and the wider security situation.
