TL;DR

France said on November 9 that an IRGC cyber unit called Shahid Kaveh carried out an October attack on refrigeration controllers at about 700 retail sites. Its published case combines technical indicators and language traces; the attribution is a government finding, not a court ruling, and Iran had not publicly responded by Monday evening, according to The Record.

France on November 9 attributed an October attack that disrupted refrigeration controllers at about 700 retail sites to Shahid Kaveh, a cyber unit France says is affiliated with Iran’s Islamic Revolutionary Guard Corps (IRGC). The government cited a collection of technical and language indicators; the attack caused food losses and at least 15 fires, according to a French cyber crisis centre report.

France’s Cyber Crisis Coordination Centre, known as C4, published a five-page report through the national cyber emergency response team, CERT-FR. It says attackers changed defrost settings on refrigeration equipment to high temperatures during the night of October 11–12. The result, the report says, was “significant losses of goods and, in at least 15 cases, fires.” The foreign ministry said more than 700 sites were affected.

The report’s attribution rests on several indicators considered together, rather than one conclusive piece of evidence. France says the attack infrastructure was also used around the same period to scan Schneider Electric equipment used in smaller energy and water production facilities. The report links the use of the industrial protocol Modbus on port 502 to activity it associates with Shahid Kaveh since at least April 2026.

French officials also cited the use of the FOFA internet-scanning tool, which the report describes as a tool habitually used by the group, and said the attack was relayed by CyberbanNews, a propaganda outlet France associates with Shahid Kaveh. The report also notes traces of Farsi in the attack infrastructure. The Paris prosecutor’s office, as reported by the Associated Press, cited Farsi use and IP addresses linked to devices in Iran.

France’s Iran-Fridge Hack Dispute What evidence did it show?

France attributed an October attack on retail refrigeration systems to Shahid Kaveh, a unit it links to Iran’s IRGC. Its case combines technical and language indicators; the allegation has not been tested in court.

700+
retail sites affected, according to France
15+
fires reported by France’s cyber crisis centre
50°C
reported peak temperature in affected systems

What France cited

Authorities said several indicators point to Shahid Kaveh when considered together.

Infrastructure

Shared attack systems

France linked the infrastructure to other activity, including scans of Schneider Electric equipment.

Tool

FOFA scanning

The report described FOFA as a tool habitually used by the group.

Language

Farsi traces

France noted Farsi in the infrastructure; prosecutors also cited IP addresses linked to devices in Iran.

Messaging

Propaganda relay

CyberbanNews, which France associates with Shahid Kaveh, relayed the attack.

What happened to stores

Attackers reportedly changed defrost settings on the night of October 11–12.

1
Controllers were exposed

France had warned that internet-accessible management interfaces were contrary to good practice.

2
Settings were altered

Refrigeration defrost settings were changed to high temperatures overnight.

3
Food and safety were hit

France reported significant product losses and at least 15 fires.

The public attribution and the criminal investigation are distinct steps.

France’s position
  • Named Shahid Kaveh as responsible for the attack.
  • Published a report combining technical and language indicators.
  • Summoned Iran’s ambassador and said it would propose EU sanctions.
Still under scrutiny
  • The attribution is a government finding, not a court ruling.
  • Paris prosecutors opened an investigation and are seeking international arrest warrants.
  • The investigation remains open; the allegations have not been tested in court.
For businessesInternet-accessible management interfaces on refrigeration and other building systems can expose stock, operations, and public safety to risk.
The takeaway
France’s case rests on a bundle of indicators, while prosecutors must still examine the evidence through legal procedures.

Costs for Stores and a Diplomatic Response

The attack affected food storage systems, turning remote access to building equipment into a direct risk to stock, store operations and public safety. France’s report records at least 15 fires and significant product losses. The Associated Press reported that temperatures reached 50°C for about six hours and that Intermarché alone reported losses of tens of millions of euros in one day. France’s foreign ministry put total food losses at several tens of millions of euros.

The attribution also carries diplomatic and legal consequences. France summoned Iran’s ambassador and said it would propose new European Union sanctions. Paris prosecutors opened a judicial investigation and are seeking international arrest warrants for the unit’s head and two deputies, according to the source reports. Those steps show the government is treating the incident as more than a private-sector disruption, while the criminal investigation will have to examine evidence under legal procedures.

For businesses, the reported access route is a practical concern. France’s computer emergency response team had warned in October that the affected controllers had management interfaces exposed to the internet, which it described as “contrary to good practice.” The episode illustrates the potential consequences of internet-accessible controls for refrigeration and other connected building systems.

How France Built Its Attribution

France’s attribution came about four weeks after the attack. On November 9, three official channels addressed the case: the foreign ministry issued a formal declaration, C4 and CERT-FR published technical findings, and the Paris prosecutor announced a judicial investigation. The foreign ministry said France was “in a position to attribute” the destructive operation to Shahid Kaveh, which it described as affiliated with the IRGC’s electronic and cyber centre.

Foreign Minister Jean-Noël Barrot made the government’s position explicit at a G7 meeting in Paris, saying, as quoted by Agence France-Presse: “I can confirm that this attack was carried out by the Islamic Revolutionary Guard Corps (IRGC) of the Islamic Republic of Iran.” The statement is France’s conclusion; it does not by itself establish the allegation in court.

The French technical report also discusses other operations it attributes to a separate IRGC unit, Shahid Shoostari, including activity against French targets since 2020. Those claims are background to the report, but the allegation about the supermarket attack concerns Shahid Kaveh. Keeping the units distinct matters because the government’s evidence and claims relate to different operations.

“I can confirm that this attack was carried out by the Islamic Revolutionary Guard Corps (IRGC) of the Islamic Republic of Iran.”

— French Foreign Minister Jean-Noël Barrot, quoted by AFP

Evidence Still Faces Legal Scrutiny

France has published a bundle of indicators, but the source material does not describe a single definitive technical link that independently proves who directed or carried out the attack. Cyber attribution can be complicated by the use of intermediary systems and misleading traces. The French report sets out why authorities connect the activity to Shahid Kaveh; it does not amount to a judicial determination.

The Paris prosecutor’s investigation remains open. An investigation is not a conviction, and the allegations have not been tested in court. Iran had not publicly responded by Monday evening, according to The Record. The available source material does not say whether the Iranian government will contest the evidence, whether the requested arrest warrants have been issued, or what further evidence prosecutors may obtain.

Some impact figures also come from different sources and are not fully reconciled in the material. France’s foreign ministry says more than 700 sites were affected, while the initial summary describes about 700. The precise total losses across all retailers and the full number of affected controllers have not been established here.

Sanctions and Prosecutorial Steps

France says it will propose new EU sanctions, but the source material does not identify the proposed measures or say when EU governments will consider them. The diplomatic response may develop as France seeks support from other member states and as Iran responds, if it chooses to do so publicly.

In Paris, prosecutors will continue the judicial investigation and pursue international arrest warrants for the alleged unit leader and two deputies. The case may test how the technical indicators described in the public report can be supported with evidence in a criminal proceeding. No court outcome or timetable is provided in the available reporting.

For affected businesses, the immediate security issue is the exposure of internet-accessible management interfaces on refrigeration controllers. France’s October warning said that exposure was contrary to good practice. The source material does not provide a complete remediation record, so it remains unclear how many affected systems have since been secured.
