France opened an investigation into cyberattacks on supermarket refrigeration units and accused Iran's Islamic Revolutionary Guard Corps of carrying out the attacks. Foreign Minister Jean-Noel Barrot said the IRGC's offensive cyber unit, Shahid Kaveh, conducted the attacks on October 11 and 12. He called the assault "unprecedented in both its scale and its level of aggression."
Hackers remotely increased temperatures in refrigeration systems to 50 degrees Celsius (122 degrees Fahrenheit) overnight when stores were closed. The temperature spikes caused fires, equipment damage, and millions of euros in food waste. Five major supermarket groups were targeted: E-Leclerc, Intermarche, Carrefour, Monoprix and Cooperative U. At least 300 Intermarche stores, more than 100 Cooperative U locations, 80 Carrefour stores, and about 25 Monoprix stores were affected.
The Paris prosecutor's office requested international arrest warrants against the leader of Shahid Kaveh and his two deputies. Barrot said the Iranian ambassador was summoned and that France would pursue sanctions against those responsible at the European level.
