France Accuses Iran of Cyber-Attack on Supermarket Fridges and Freezers

France has accused Iran's Islamic Revolutionary Guard Corps (IRGC) of carrying out a major cyber-attack that caused supermarket refrigerators and freezers across the country to heat up, potentially destroying millions of euros worth of food.

The French government has accused Iran of being behind a series of cyber-attacks targeting refrigeration systems in supermarkets, in an incident described by officials as an unprecedented act of sabotage on French soil.

French Foreign Minister Jean-Noël Barrot said the attacks were carried out by Iran's Islamic Revolutionary Guard Corps, warning that France would push for European sanctions against those believed to be responsible.

The incident took place last month and affected hundreds of supermarkets, with hackers gaining access to software controlling refrigeration equipment.

Fresh and frozen food was left exposed to rising temperatures, with losses estimated to run into millions of euros.

Iran has not yet responded to the allegations.

Hundreds of supermarkets affected

The first major wave of attacks took place on 11 October, when hackers reportedly gained control of software used to regulate temperatures in supermarket refrigerators and freezers.

More than 100 Coopérative U supermarkets were affected, alongside approximately 180 stores belonging to Intermarché and its Netto brand.

Other major retailers, including Carrefour, Monoprix and E.Leclerc, were also impacted.

In some stores, refrigeration temperatures reportedly climbed as high as 50C overnight, putting large quantities of food at risk.

The software targeted was supplied by Danish engineering company Danfoss and allows supermarket operators to monitor and control refrigeration systems remotely.

The scale of the incident has raised serious questions about the vulnerability of essential retail infrastructure to cyber-attacks.

France threatens European sanctions

Foreign Minister Jean-Noël Barrot described the incident as unprecedented in both its scale and aggression.

He said it represented the first large-scale cyber-attack aimed at sabotage on French national territory and constituted a serious threat to national interests and public security.

The French government has summoned Iran's ambassador in Paris to formally protest over the allegations.

Mr Barrot said France intended to pursue sanctions at European level against those responsible and would consider further proportionate measures to discourage similar attacks in the future.

However, the government has not publicly explained the evidence behind its conclusion that Iran was responsible.

Attributing cyber-attacks to particular countries or organisations can be extremely difficult, as hackers often use techniques designed to conceal their identities and locations.

Investigators examine Iranian cyber unit

Separately, the Paris prosecutor has confirmed an investigation involving the head of an Iranian-linked offensive cyber unit and two of his deputies.

Paris prosecutor Laure Beccuau identified the group as Shahid Kaveh, which she said was affiliated with the Islamic Revolutionary Guard Corps' electronic and cyber centre.

The investigation adds another dimension to France's response as authorities attempt to establish responsibility for the attacks.

Cyber-attacks spread across Europe

The incident in France was followed by another wave of attacks last week, affecting more than 100 supermarkets across seven other European countries.

Belgium and Luxembourg were among the countries affected, while smaller numbers of stores in Sweden, Ireland, the Netherlands, Estonia and Finland also experienced problems.

It remains unclear whether the attacks across Europe were connected to the earlier incidents in France.

Cyber-security experts have been examining possible suspects, with Iran among the groups and state actors considered.

Two hacking groups aligned with Russia claimed responsibility for some of the incidents on Wednesday. However, those claims have been treated with scepticism.

No confirmed public evidence has established that the Russian-aligned groups were responsible.

Serious questions over supermarket security

The attacks have highlighted how modern supermarkets depend on connected computer systems to manage essential operations.

Refrigeration equipment may appear separate from the technology normally associated with cyber-security, but remote-control software can provide hackers with an opportunity to disrupt vital services.

A successful attack on these systems can have consequences beyond damaged equipment, potentially affecting food safety, business operations, supply chains and consumer confidence.

For France, the allegations against Iran have also raised the possibility of a wider diplomatic confrontation.

The investigation remains ongoing, and the full extent of the damage and the evidence linking the attacks to Iran have not yet been made public.

The Real Terryo Daily Round-Up Says

This incident demonstrates just how vulnerable everyday services can become when essential equipment is connected to computer networks.

Most shoppers would never imagine that a supermarket's refrigerators could become the target of an international cyber-attack, yet the consequences could be extremely expensive.

If hackers can interfere with systems responsible for keeping food safe, businesses and governments need to take the security of these networks far more seriously.

France's accusations against Iran are extremely serious, but responsibility must ultimately be established through evidence and a proper investigation.

The attacks also raise wider concerns for other European countries. Supermarkets, food suppliers and essential businesses must consider whether their systems are sufficiently protected against increasingly sophisticated cyber threats.

The Real Terryo Daily Round-Up will continue to follow developments as investigators examine the attacks and France considers its response.
