Manufacturing is now one of the most targeted industries for ransomware, and the reason is simple: attackers know a stopped line forces fast payment. OT and IT environments that were never designed to touch are now connected, aging equipment runs on systems that cannot be patched, and defense-adjacent suppliers face CMMC and DFARS requirements flowing down through their contracts whether they are ready or not. Meanwhile plants still depend on copper lines for fire panels, elevators, and alarms that carriers are sunsetting, connectivity gaps stall smart factory ambitions, and energy costs eat margin on every shift.
