In November 2026, a series of cyberattacks compromised refrigeration systems across Europe, affecting approximately 940 locations. These included critical infrastructure such as supermarkets and blood storage facilities.

Attackers manipulated remote control systems, dangerously increasing refrigerator temperatures, with some reaching as high as 80°C. This exploitation targeted outdated refrigeration systems, raising concerns about vulnerabilities in cold chain logistics for food and medical supplies.

The French government has attributed the attacks to 'Shahid Kaveh,' a hacking unit suspected to be linked to Iran's Revolutionary Guard. This attribution has led to significant concerns and potential retaliatory measures from the European Union against Iran.

Cybersecurity researchers noted 256 attempted attacks originating from 91 sources over a span of 10 days leading up to the main event.
