Frostbyte10 bugs put thousands of #refrigerators at major grocery chains at risk

Major #flaws uncovered in #Copeland #controllers: Patch now

10 #vulnerabilities in Copeland controllers, which are found in thousands of devices used by the world's largest #supermarket chains and cold #storage companies, could have allowed miscreants to manipulate temperatures and spoil food and medicine, leading to massive supply-chain #disruptions.

The flaws, called #Frostbyte10, affect Copeland E2 and E3 controllers, used to manage critical building and #refrigeration systems, such as #compressor groups, #condensers, walk-in units, HVAC, and lighting systems. Three received critical-severity ratings.

Operational technology security firm #Armis found and reported the bugs, and #firmware updates have since been issued. Upgrading to Copeland firmware version 2.31F01 mitigates all these security issues.
