UK Power Plant Shut for Four Days in Reported Iran-Linked Cyberattack

A small British electricity generator was forced offline for four days in July by a cyberattack attributed in reports to Iran-linked hackers, in what is believed to be the first successful Iranian-affiliated shutdown of a UK power facility. Officials withheld the plant’s name and location for security reasons, and staff restored operations after four days. The outage did not affect Britain’s wider electricity supply or production, and the government later briefed power-company executives and sent businesses protective guidance. The case was reportedly referred to the National Cyber Security Centre, which declined comment on the specific incident.
