TL;DR
France said on November 9 that an Iranian Revolutionary Guard Corps cyber unit was responsible for an October attack that disrupted refrigeration controllers at about 700 retail sites. The government cited several technical and operational indicators; the attribution remains France’s assessment, and no court has tested the evidence.
France on November 9 attributed an overnight cyberattack on supermarket refrigeration systems to Shahid Kaveh, a unit it says is affiliated with Iran’s Islamic Revolutionary Guard Corps (IRGC). The attack affected controllers at about 700 retail sites, France said, causing substantial food losses and at least 15 fires; the attribution has not been tested in court, and Iran had not publicly responded by Monday evening, according to The Record.
France’s Cyber Crisis Coordination Centre, or C4, said attackers accessed refrigeration controllers over the internet during the night of October 11 to 12 and changed their defrost settings to high temperatures. Its report says the incident caused significant losses of goods and fires in at least 15 cases. The foreign ministry said more than 700 retail sites were affected and described the food losses as several tens of millions of euros. The Associated Press reported that temperatures reached 50 degrees Celsius for about six hours and that Intermarché alone reported losses in the tens of millions of euros in one day.
Three parts of the French state announced measures on November 9. The foreign ministry issued a formal attribution, Foreign Minister Jean-Noël Barrot confirmed the accusation at a G7 meeting in Paris, and the Paris prosecutor opened a judicial investigation. France also said it would propose new European Union sanctions. The prosecutor is seeking international arrest warrants for the alleged unit head and two deputies, according to reporting by the AP.
The French technical report, published by CERT-FR as CERTFR-2026-CTI-009, sets out several indicators behind the attribution. It cites shared attack infrastructure, use of the internet-scanning tool FOFA, a propaganda channel that relayed the operation, and traces of Farsi. The prosecutor’s office also cited Farsi and IP addresses linked to devices in Iran, the AP reported. France has presented these as evidence supporting its assessment, not as a judicial finding.
What the Fridge Hack Reveal Tells Us About France’s Iran Accusation
France says an Iranian cyber unit targeted supermarket refrigeration systems. Its attribution is an official assessment, not a finding tested in court.
What happened
France says attackers accessed internet-connected controllers overnight on October 11–12 and raised defrost settings.
The systems were reachable over the internet, contrary to good practice, France’s cyber response team said.
High-temperature defrost settings disrupted refrigeration and food storage.
France reported substantial food losses and fires at at least 15 sites.
Why France points to Shahid Kaveh
The government cites a bundle of technical and operational indicators, rather than one publicly conclusive proof.
Shared attack resources
France says infrastructure overlapped with scanning activity involving Schneider Electric equipment.
FOFA use
The report says the unit habitually uses the internet-scanning tool FOFA.
Farsi traces
France and prosecutors cited Farsi traces; prosecutors also cited IP addresses linked to devices in Iran.
Propaganda channel
The report points to CyberbanNews relaying the operation after the attack.
What the accusation does—and does not—establish
- Formal attribution to Shahid Kaveh, described as affiliated with Iran’s IRGC.
- Paris prosecutor opened a judicial investigation.
- France says it will propose new EU sanctions.
- The attribution has not been tested in court.
- Iran had not publicly responded by Monday evening, according to The Record.
- Sanctions, legal findings and the full damage remain unsettled.
What businesses should take from it
Connected building systems can turn a network weakness into disruption of everyday operations.
- Review whether refrigeration and other operational controllers are exposed to the internet.
- Treat cyber security as a food-safety and physical-operations concern.
- Follow the investigation and any EU sanctions decisions for practical implications.
Risks to Connected Food Systems
The incident shows how a vulnerability in ordinary business equipment can produce consequences beyond a computer network. Refrigeration controllers govern the temperature of food storage; when their settings were changed, the reported effects included spoiled goods and fires. The equipment was not described as an obscure or newly invented technology. France’s computer emergency response team had warned in October that the affected controllers had management interfaces exposed to the internet, which it said was contrary to good practice.
For retailers and other operators of connected buildings, the immediate concern is practical: internet-accessible control systems can become a route to disruption of physical operations. The reported losses also put a monetary scale on that risk, although the estimates come from French authorities and a company report cited by the AP, rather than from a single audited total. For governments, the case tests how a state-backed cyber attribution translates into consequences. France has announced diplomatic and legal steps and plans to seek EU sanctions, but the effects of those measures remain to be seen.

From Attack to French Attribution
The attack happened on October 11–12; France announced its attribution four weeks later, on November 9. The foreign ministry said the actions were carried out by Shahid Kaveh, which it described as affiliated with the IRGC’s electronic and cyber centre. Barrot told reporters at the G7 meeting that the IRGC carried out the attack. Those statements establish the French government’s position; they do not independently settle responsibility.
The attribution relies on a collection of indicators rather than one conclusive public proof. C4 said infrastructure used in the attack was also used around the same period to scan Schneider Electric equipment used in smaller energy and water production units. The report links the relevant Modbus protocol activity to Shahid Kaveh from at least April 2026, and says the group habitually uses FOFA. It also points to CyberbanNews, which relayed the attack from October 13 and which the report associates with the unit.
France’s report also attributes earlier operations against French targets since 2020 to another IRGC unit, Shahid Shoostari, including an attack on the Charlie Hebdo website in 2023 and an attempted hijacking of video display screens during the 2024 Paris Olympics. These are separate allegations in the report; the current case concerns Shahid Kaveh and the supermarket refrigeration attack.
“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 and Response Still Pending
The public evidence is a bundle of indicators, not a single publicly conclusive demonstration of who operated the systems. Cyber attribution can be complicated by relayed traffic and misleading clues, and the French report presents the indicators as the basis for the government’s assessment. The allegations have not been tested in court. An investigation does not establish the guilt of the people named or prove that they directed the attack.
Iran had not publicly responded by Monday evening, according to The Record. The total damage is also not presented as one independently verified figure: the foreign ministry gave an estimate of several tens of millions of euros, while the AP cited Intermarché’s reported losses. The available source material does not specify how many controllers were directly accessed, whether all affected sites suffered the same level of damage, or whether further technical findings will be released.
Sanctions and Investigation Ahead
France says it will propose new EU sanctions, but the source material does not state which measures it will seek or when EU governments will consider them. The diplomatic response already includes summoning Iran’s ambassador. The next public developments may clarify whether France’s partners support the attribution and what sanctions, if any, follow.
The Paris judicial investigation is also continuing. Prosecutors are seeking international arrest warrants for the alleged unit head and two deputies, according to the AP. The process will determine what evidence can be used in the legal case and whether suspects can be identified or brought within the reach of French authorities. Until then, the attribution remains France’s official accusation, while the technical details, legal findings and Iran’s response remain developing.
