Hackers linked to Iran temporarily shut down a small UK power plant for four days due to a cyber-attack, according to reports from The Guardian, Daily Mail, and CNBC. The incident involved a small-scale energy generator and posed no risk to the wider energy system.

The attack occurred last month, as first reported by The Sunday Telegraph. A spokesperson for the Department for Energy Security and Net Zero stated that there was no threat to the broader energy infrastructure. The National Cyber Security Centre (NCSC) is investigating the breach but has not received any reported outages from regulated operators of power stations.

This incident marks an apparent escalation in cyber threats posed by Iran, particularly after the UK allowed the US to launch defensive operations against Tehran from British bases. Richard Horne, NCSC's chief executive, warned earlier this year that hostile states like Russia, China, and Iran are increasingly targeting systems behind the UK’s key services.

The Iranian government has been accused of carrying out cyber-attacks on various countries in the past. US government security agencies have also issued warnings about cyber-attacks by hackers linked to the Islamic Revolutionary Guard Corps (IRGC). The IRGC stated that any base used for aggression against Iran would be a legitimate target for their forces.
