Iranian Hackers Reportedly Shut Down UK Power Plant for Four Days

Iranian hackers reportedly shut down a small British power plant for four days in what The Telegraph described as an unprecedented cyberattack.

According to the newspaper, the incident marked the first known case of Iranian hackers successfully taking a power facility offline in the UK. Officials have not identified the plant, citing security concerns, but said it was a relatively small facility.

The outage did not disrupt Britain’s wider electricity supply or significantly affect national energy generation. However, the incident prompted UK authorities to brief energy-company executives and issue guidance to businesses on cybersecurity measures and next steps.

The reported attack came amid a wider series of cyber incidents targeting US water infrastructure, which affected systems across 12 states and raised concerns among American officials.

The incident has renewed warnings about the vulnerability of critical infrastructure to state-linked cyberattacks.
