Supermarket freezers in several European countries are tampered with remotely, a month after France's wave
Bloomberg's country-by-country account shows how one brand of refrigeration controller tied the incidents together.
Overnight from November 1 to 2, refrigeration systems at supermarkets in Belgium, Ireland, Sweden, Finland, Estonia and the Netherlands were remotely tampered with, forcing stores to throw out chilled and frozen food. In one Swedish ICA store, freezers were set to 50°C, Bloomberg reports (via Claims Journal).
Carrefour Belgium said 15 of its 700 stores were affected, Delhaize confirmed an "IT incident," Ireland's Musgrave said 13 SuperValu stores were hit, and Coop Sweden confirmed a hack at seven stores. Danish manufacturer Danfoss said the incidents involved its products, as in October, when about 700 French stores had refrigeration disabled; it told Dutch broadcaster NOS that 17 Dutch facilities were affected, according to ABC News.
No group has claimed responsibility. Bloomberg notes that equipment running legacy software that can't be patched may have stayed vulnerable after October. Separately, the Pentagon is examining freezer failures at several US military facilities; no link has been shown.
