US agencies warn of refrigeration hacks amid suspected attacks on military bases

U.S. and European agencies warned of an ongoing campaign that manipulates electronic refrigeration controls—forcing heating/defrost cycles and obscuring temperature monitoring—resulting in spoiled inventory, damaged equipment and safety hazards at supermarkets, military commissaries and blood banks across multiple countries; authorities recommend removing internet-exposed controls, securing remote access, segmenting networks, changing defaults, patching and replacing unsupported devices.
