French foreign minister vows European sanctions against Tehran over ‘unprecedented’ hacks last month

France has said Iran was responsible for a massive cyber-attack on supermarket freezers and chiller cabinets that was described by its foreign minister as being an act of “unprecedented scale and unprecedented aggression”.

Jean-Noël Barrot said “Europe-wide sanctions” would be imposed against those responsible, adding that the attacks – which took control of digital thermostats to push temperatures up to above 50C – constituted “a major violation of the nation’s interests”.
