Hackers reportedly alter French blood plasma freezer settings via provider Coolworld

Reports say an intrusion into refrigeration control equipment operated by Coolworld◼, a service provider to EFS, was detected overnight on 1 to 2 November 2026, with freezer setpoints allegedly changed from about -30°C to 110°C. No CVE, affected controller model or entry vector is given in the source, and the article is truncated before the statement from France's Health Ministry. Defenders in healthcare and cold-chain operations should audit remote access to building or process controllers, alarm on setpoint changes, and verify independent temperature monitoring.
