Cyberattack disrupts cooling systems at hundreds of French supermarkets
Unknown attackers disabled supermarket cooling systems at hundreds of stores in France overnight on Monday.
Food warmed in refrigerators and freezers, so stores had to throw away items that could pose health risks.
Fires also broke out at several locations.
French investigators described the incident as a large-scale attack, and the national cybersecurity agency is investigating.
Control devices made by Danish company Danfoss may have been manipulated, but this has not been confirmed.
A Dutch supermarket chain also reported a security problem, though it is not clear whether the incidents are connected.
The attack matters because failures in food refrigeration can threaten public health and disrupt supermarket operations.
