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.

Over 800 N-able N-central servers remain unpatched against two critical vulnerabilities, CVE-2025-8875 and CVE-2025-8876, which are currently being exploited. N-able has urged administrators to upgrade to the patched version 2025.3.1, while CISA has mandated federal agencies to mitigate these vulnerabilities within a week. Shadowserver Foundation reports that most of the vulnerable servers are located in the U.S., Canada, and the Netherlands.
