• Major French supermarket chains experienced a cyberattack affecting their refrigeration systems.
• Over 300 stores were involved, with temperatures in refrigeration units reportedly reaching 50°C.
• The attack has raised concerns over food security and resulted in significant food waste and financial losses.
• Investigations are underway to assess the impact and identify vulnerabilities in the affected technologies.
• Europes' food and agriculture commissioner highlighted the seriousness of the exploitation of food by such attacks.

On October 12, several major French supermarket chains, including Intermarché, Coopérative U, and E. Leclerc, reported a serious cyberattack that led to refrigerator failures across hundreds of stores. Hackers gained control of the software regulating the temperature of refrigeration units, leading to substantial spoilage of fresh and frozen food, which could amount to millions of euros in losses. The chief executive of Coopérative U, Dominique Schelcher, labeled the incident as "unprecedented" and extremely serious, demanding immediate actions to address the situation, according to Le Monde and BBC.

Reports indicate that approximately 150 - 200 Intermarché outlets were directly affected, alongside nearly 100 Coopérative U stores. Some fridges reached temperatures as high as 50°C, prompting supermarket staff to throw away all exposed food to prevent health risks. Additionally, Paris prosecutors confirmed that the cyberattack triggered outbreaks of fire in some locations, emphasizing the severity of the incident, as noted by CBS News and Le Monde.

The incident involved several other supermarket chains, with Carrefour reporting that 80 of its stores were impacted. However, the majority of its operations remained unaffected. Following the attack, Coopérative U's CEO emphasized the need for an investigation into the vulnerabilities exploited, particularly noting that the hacking targeted systems essential for food preservation. Experts noted that the sophistication of the attack raises alarms regarding food security in Europe, as highlighted by the EU's food and agriculture commissioner, according to BBC and CBS News.

As investigations proceed, the Paris prosecutor's office aims to identify victims and ascertain the extent of damage incurred from lost food supplies. This cyberattack reflects a growing concern about hybrid threats in Europe, suggesting that critical infrastructure, including food supply systems, could be increasingly targeted to exploit weaknesses. Experts from the cybersecurity field have begun analyzing the implications of interconnected refrigeration units, raising serious questions about the protections in place against such attacks, as mentioned by CBS News and Le Monde.
