Supermarket chains in Belgium, Sweden and other European countries report refrigeration failures after suspected cyberattacks overnight on November 2.

A second wave of suspected cyberattacks affected supermarket refrigeration systems in Belgium, Luxembourg, Sweden, Estonia, Ireland and the Netherlands, causing freezers to reach temperatures of 50-55°C or higher and spoiling food.

No confirmed attacker, malware, exploited vulnerability or entry point was named, though Danfoss controllers with outdated firmware are implicated in some cases.
