Cyber-attack on French supermarket freezers has geopolitical context

Summary

France has attributed a cyber-attack on supermarket refrigeration systems to hackers operating under Iran's Islamic Revolutionary Guard Corps. The attackers used default passwords to access fridge controls, raising temperatures so high that some units caught fire and forcing employees to discard spoiled meat and ice cream. A Sophos director said the attack's relatively unsophisticated nature fits Iranian capabilities, and a wave of similar defrosting hacks across Europe is presumed to be linked.
