German watchdog warns some cooling systems remain vulnerable to hacking

Germany’s information security office BSI warned on Friday of ongoing vulnerabilities in some of Danish firm Danfoss’ industrial cooling appliances, following cyberattacks on refrigeration systems across Europe.

The systems in question should be taken offline when possible or otherwise any connection should be secured via VPN, or Virtual Private Network, BSI said in a security advisory on its website.

Hacking attacks on European supermarkets spread across the continent last week, hitting fridges and ​freezers from Sweden to Belgium and forcing stores to throw away food in an incident that echoed a similar attack in France last month.
