When defrost becomes sabotage: 3 OT lessons from France’s supermarket attack

On the night of 11 October, someone remotely put the cold cases of several hundred French supermarkets into defrost. At Intermarché and Netto stores, fridges and freezers warmed to around 50°C and stayed there for about six hours, according to Les Mousquetaires, which expects losses in the tens of millions of euros. By morning, staff were filling skips with meat, frozen goods and vegetables.
