In July, hackers linked to Iran forced a UK power plant offline for four days,
the government said; officials declined to identify the facility and described
it as relatively small. Separate attacks on US water infrastructure last month
affected facilities across 12 states and drew White House attention. Britain
operates dozens of small, often intermittently run power plants. The episode
follows prior major UK cyber incidents that disrupted the NHS, school IT
services and manufacturers including Jaguar Land Rover.
