Iranian hackers ‘shut down British power plant for four days’ in unprecedented cyber attack
Iranian hackers reportedly shut down a small UK power plant for four days in what has been described as the first and most effective cyber attack of its kind on Britain's energy infrastructure. Although officials insist there was no wider risk to the national energy system, the breach is being seen as a stark warning about the vulnerability of the UK's critical infrastructure to state-linked cyber threats.
The unnamed facility was forced offline while engineers worked to restore systems, prompting the Government to brief power company executives and alert the National Cyber Security Centre, which is now investigating. The incident coincided with a wave of suspected Iran-linked attacks on US water utilities across more than a dozen states, including one in Arkansas and over 30 breached systems in Minnesota alone. British infrastructure, including the NHS, schools and manufacturers such as Jaguar Land Rover, faces thousands of cyber attacks daily, with Cabinet Office research putting the chance of a serious successful attack at between five and 25 per cent.

Iranian hackers reportedly disabled a British power plant for four days, in what is being described as a landmark cyber attack on UK critical infrastructure. Attacks of this kind typically target the computer systems that control industrial equipment, rather than stealing data, and can cause real-world disruption such as outages. The alleged perpetrators are described as Iranian hackers, though it is not yet clear whether they are believed to be state-backed or acting independently.
Cyber attacks on power infrastructure are taken particularly seriously because electricity supply underpins hospitals, transport, communications and other essential services, so any prolonged outage has knock-on effects well beyond the site itself. The UK has previously warned about the risk of state or state-linked actors targeting its energy network as part of wider tensions with Iran.
At this stage, key details commonly used to assess incidents like this – such as which power plant was affected, when the outage happened, how it was discovered, and what UK authorities and the energy operator have said in response – are not yet confirmed.
