Major vulnerabilities known as Frostbyte10 have been discovered in Copeland controllers used in thousands of refrigeration systems at grocery chains, potentially allowing attackers to manipulate temperatures and disrupt supply chains. Armis identified ten critical flaws, prompting Copeland to issue firmware updates and CISA to urge immediate patching of affected systems. While no exploitation has been confirmed in the wild, the pervasive use of these controllers makes them a prime target for malicious actors.
