France is accusing Iran of carrying out a mass cyberattack that targeted freezers at hundreds of French grocery stores in October. The disruption spoiled food, damaged equipment, and pushed an ordinary piece of supermarket infrastructure into the center of an international security dispute.
French Foreign Minister Jean-Noël Barrot said the Islamic Revolutionary Guard Corps conducted [1] the attack. He described the operation as “unprecedented in both its scale and its level of aggression,” according to the BBC.
The attack reportedly caused millions of euros in food losses. Refrigeration systems that stores depend upon to preserve inventory instead became tools for widespread disruption.
The cyberattack “marks the first large-scale cyberattack aimed at sabotage on our national territory, and it constitutes a major attack on the nation’s interests and the security of the French people,” Barrot said.
France said it would pursue sanctions at the European level against everyone responsible for the attack. The country also summoned Iran’s ambassador for a formal reprimand, according to Barrot.
The accusation comes after France looked askance at America during its military action against Iran. Paris is now pointing directly at the Iranian regime’s Islamic Revolutionary Guard Corps over a cyber operation that struck French territory and damaged private businesses.
Paris prosecutor Laure Beccuau said an investigation was opened into Shahid Kaveh. The organization was described as the Islamic Revolutionary Guard Corps’ cyber warfare unit.
The hackers targeted supermarket refrigerators and freezers that could be controlled remotely, according to CNN. The systems were switched to their defrost cycles, causing food to spoil and damaging some of the equipment.
Hackers turned refrigeration systems into heaters and drove temperatures to 50°C. Food was destroyed, some fires occurred, and French blood banks were targeted, forcing staff to move supplies into unaffected refrigerators.
Some affected equipment was outdated, connected to the internet, and vulnerable to basic security failures. One controller model had a hidden password calculated from the date, although nobody had established whether attackers exploited that flaw.
The French incidents did not remain an isolated case. According to the U.K. Guardian, hacks this month affected refrigerators in Belgium, Sweden, Luxembourg, Finland, Ireland and Estonia.
No hacktivist organization has claimed responsibility for the wider activity. North Korea, Russia and China were also identified as governments that engage in hacking and could potentially be responsible for incidents whose perpetrators have not been established.
France suspects IRAN hacked its supermarket fridges. But the embarrassing part might be how EASY it was.
Hackers turned refrigeration systems into heaters, pushing temperatures to 50°C, destroying food and even causing fires.
Then French blood banks were targeted. Staff had to move supplies into unaffected refrigerators.
French officials now apparently suspect Iranian hackers, but the evidence hasn’t been made public.
Meanwhile, some affected equipment was outdated, exposed to the internet and vulnerable to basic security failures.
One controller model even had a hidden password calculated from the DATE.
Nobody has established whether that flaw was exploited.
If Iran did it, that’s a serious act of cyberwarfare. But who left the doors open?

The United States had already experienced similar trouble in August, when commissaries at military bases were hit. On Aug. 26, malfunctions affected commissaries at Army base Fort Huachuca in Arizona, Naval Station Newport in Newport, Rhode Island, and other bases, according to The New York Times.
Military officials are investigating whether those August incidents were connected to the broader hacking activity that followed. The investigation leaves officials examining whether problems at American military commissaries were part of the same pattern affecting commercial refrigeration systems overseas.
Experts warned that the private sector could face serious trouble because older food and beverage systems were historically kept offline. Connecting that equipment creates vulnerabilities in systems responsible for storing food and maintaining safe temperatures.
“We have a huge legacy problem in food and beverage as a whole,” said Sean Tufts, chief technology officer of Claroty, a cybersecurity company in New York. “Historically, those kinds of things were always offline.”
Richard Jones, a University of Edinburgh professor of criminology who studies cybersecurity and supply chains, said Western nations frequently treat stable food systems as a given. The attacks offered a blunt reminder that basic infrastructure can become a target.
“Food security is often taken for granted in Western countries,” Jones said. “This is a wake-up call.”
