A cyberattack on internet-connected commercial freezers reportedly spread across shops in 11 European countries on 1 November, with three French blood-storage sites also affected. Workers were alerted by alarms in time to intervene, Scientific American’s Science Quickly reports.
Why it mattersThe podcast says attackers exploited freezer defrost heaters, keeping them on long enough to push temperatures as high as 122°F. Pentagon officials also suspect similar hacking may explain freezer problems at US military bases in August, though the account does not establish that connection. Remote monitoring can be useful, until it becomes a route in. The report says firewalls and up-to-date equipment can help protect these connections, but operators need the time and information to maintain them.
Discuss: Which should come first for connected industrial equipment: stronger security requirements or better support for operators?
