Supermarket freezer systems in at least seven European countries were remotely heated to as high as 50C
Supermarkets across at least seven European countries were hit by another wave of suspected cyber incidents between late Nov. 1 and early Nov. 2, with refrigerated units remotely switched to higher temperatures and, in some cases, heated to as much as 50 degrees Celsius. Bloomberg said the pattern resembled the France incident reported in October, while The Guardian counted impacts across at least seven countries. Reuters said 15 of Carrefour’s 700 stores in Belgium were affected, along with five Spar stores under Colruyt and seven of Coop’s 800 stores in Sweden. The Guardian also cited 15 Intermarché stores in Belgium, 13 of SuperValu’s 223 stores in Ireland, and at least 17 stores in the Netherlands, mostly small local outlets. AP reported that Delhaize saw dozens of affected stores, mainly in Belgium and a smaller number in Luxembourg. Danish refrigeration manufacturer Danfoss told Bloomberg its products were involved, and Belgian service provider Sabcobel said attackers remotely switched units into defrost mode, matching the method seen in France. French cyber agency CERT-FR had already warned in October that attacks targeting some Danfoss models were likely still underway and that factory resets alone would not stop reinfection if devices remained online and unpatched.
