Source SecurityWeek

Description

In October 2026, a cyberattack attributed to Iran's Islamic Revolutionary Guard Corps targeted refrigeration systems in about 700 supermarkets across France, causing temperatures to rise to 50°C for approximately six hours. This attack led to significant financial losses, including tens of millions of euros reported by the Intermarché supermarket chain. French authorities have opened a judicial investigation and are seeking European sanctions against those responsible. The attack is described as unprecedented in scale and aggressiveness, representing a major threat to national interests and public security.

Impact

The attack disrupted refrigeration systems in approximately 700 supermarkets, causing temperatures to reach damaging levels and forcing disposal of perishable goods. The Intermarché chain alone reported losses amounting to tens of millions of euros in a single day. The incident represents a significant economic impact on the retail sector and poses a serious threat to public safety and national security. It also marks a precedent for large-scale cyber sabotage targeting critical infrastructure in France.

Defensive guidance

French authorities have initiated a formal judicial investigation and are pursuing international arrest warrants for those responsible. France plans to impose European-level sanctions against the perpetrators. The national cybersecurity agency ANSSI is actively investigating and attributing the attack. No specific technical mitigations or patches are detailed in the available information. Organizations operating refrigeration systems should review their security controls and monitor for unauthorized access, but no direct remediation guidance is provided by the vendor or authorities at this time.

Summary

On October 12, 2026, attackers remotely compromised refrigeration systems in hundreds of French supermarkets, causing temperatures to soar to 50°C for about six hours and resulting in the spoilage of fresh and frozen goods. French prosecutors and the national cybersecurity agency ANSSI attributed the attack to the Shahid Kaveh group, affiliated with Iran's Islamic Revolutionary Guard Corps. The investigation identified use of Farsi language and IP addresses linked to Iran. This cyberattack is considered the first large-scale sabotage on French soil, prompting France to summon the Iranian ambassador and pursue European sanctions. The incident caused significant economic damage and heightened concerns about critical infrastructure security.
