Three French blood-service cold rooms had temperatures altered via a supplier attack; no products were lost, and US agencies warned operators.

France’s national blood service said a cyberattack on a refrigeration supplier changed cold-room settings at three sites, reported on November 2. Monitoring caught the changes; staff moved plasma and other products, and collection and distribution continued with no reported health impact or product loss. SecurityWeek says attackers tried to set temperatures to 110°C; The Register separately reports European supermarket attacks that raised temperatures to 50°C. The Record counts a wave across 11 European countries, while Security Affairs cites supermarket incidents in eight. CISA, the FBI and partners warned operators of internet-connected refrigeration, including possible military and retail targets; TechCrunch says an Iran link is unconfirmed.
