Just weeks after hundreds of grocery stores in France were hit by cyber-attacks, shops in Belgium, Sweden, Ireland, Luxembourg and Estonia have also been attacked.
The attacks, which increased temperatures in fridges and freezers across Europe, have forced stores to throw away lots of food. In some cases, fridges in stores got to 50C, and some supermarkets in France have experienced fires.
