France accuses Iran of supermarket fridge hacking

France has accused Iran of being behind cyber-attacks that raised the temperatures of supermarket fridges and freezers.

Speaking at a news conference, French Foreign Minister Jean-Noël Barrot said the attack was carried out by the Islamic Revolutionary Guard Corps (IRGC) of Iran.

He said the attack was "unprecedented in both its scale and its level of aggression", adding that the country would "implement sanctions at the European level against all those responsible for this attack."

The cyber-attack last month saw fridges and freezers in hundreds of supermarkets across France heated up, which spoilt fresh and frozen food estimated to be worth millions of euros.
