Hackers disrupt refrigeration systems at European supermarkets
By Bill Toulas
AI Summary
Attackers remotely modified temperature settings on internet-exposed refrigeration controllers at over 100 supermarket locations across Belgium, Sweden, Ireland, Estonia, and other European countries overnight on November 2, forcing stores to discard spoiled chilled and frozen food. Danish manufacturer Danfoss confirmed its refrigeration control systems were among those targeted in this second wave of attacks following an earlier French incident, spotlighting critical OT/ICS exposure in cold-chain infrastructure. No authentication hardening or network segmentation appears to have prevented attackers from reaching operational controls.
