Hackers linked to Iran have been blamed for a cyber-attack that led to the temporary shutdown of a British power plant last month. The incident, which caused the power plant to be shut down for four days, involved a small-scale energy generator.
The UK government stated that there was no risk to the wider energy system at any point. A spokesperson for the Department for Energy Security and Net Zero confirmed the incident impacted a small-scale energy generator and reiterated the resilience of the UK's energy system.
The incident marks an apparent escalation in the threat from Iran, following the UK's permission for the US to launch "defensive" operations against Tehran from British bases. The National Cyber Security Centre (NCSC) is understood not to have received any reported outages from regulated power station operators.
Richard Horne, the NCSC's chief executive, warned this year that hostile states, including Russia, China, and Iran, are increasingly targeting systems behind key UK services. The UK government stated last month it was "ready to defend itself" after Iran's military warned that any bases used by the US were "legitimate targets."
