Iranian hackers shut down UK power plant for four days

Hackers linked to Iran reportedly succeeded in shutting down a British power plant for four days in what is being described as an unprecedented cyberattack against the UK’s energy infrastructure.

The targeted facility has not been identified, but British officials said it was a relatively small power station and that its shutdown did not affect the country’s wider electricity supply. Nevertheless, the incident is significant because it appears to mark the first known case in which hackers linked to the Iranian regime successfully forced a British power-generation facility offline.


Employees spent four days restoring the plant to operation.


The attack was reported to Britain’s National Cyber Security Centre, which operates under the GCHQ intelligence agency. Following the incident, the British government briefed senior energy executives and circulated additional security guidance to companies operating critical infrastructure.
