On November 2, local time, the temperature in European supermarket refrigerators soared up to 50 degrees Celsius.

When freezer doors are opened, melted ice cream drips down.

Employees sweep spoiled meat and frozen foods into garbage bags.

The cause was a hacking attack.

Someone accessed the facility control system and remotely manipulated the refrigeration and freezing equipment, switching them to "defrost mode" to drive up the temperatures.

Similar incidents occurred in France last month and at a US military base food store last August.

However, it has not yet been revealed who carried out these attacks or why.
