Hackers altered temperature settings at regional centers following a wave of attacks on European supermarkets

France's national blood service is conducting a judicial investigation into a cyberattack that occurred between November 1 and 2. Hackers gained control of refrigeration systems at three regional storage centers.

Intruders modified the defrost and temperature settings of cold storage units. Some equipment had parameters adjusted from minus 30 degrees to plus 110 degrees. Alarms and the intervention of technicians prevented the loss of blood samples or products.

The incident took place on the same night that supermarkets in nine European countries reported similar breaches. France is investigating whether there is a connection between the attack on the blood service and previous episodes that affected the retail sector.

In October, about 700 French commercial establishments suffered attacks that raised freezer temperatures and caused financial losses. Intelligence reports point to a cyber unit of Iran's Revolutionary Guard as responsible for these actions.

The French government has requested international arrest warrants for the identified suspects. The Ministry of Foreign Affairs seeks the implementation of European Union sanctions against those involved in the attacks.
