A cyber attack resulted in the successful shutdown of a UK power facility. Operational outage and loss of power generation for four days. The incident underscores the severe risks associated with legacy operational technology (OT) within critical national infrastructure. While the facility recovered within four days, the breach demonstrates the capability of state-sponsored actors to cause physical operational disruptions. The primary concern is whether such attacks can pivot from smaller facilities to the wider national grid.
