Iran-linked hackers have been blamed for a cyber-attack that temporarily shut down a small UK power plant, reports the Guardian.
The facility was reportedly offline for four days following the attack last month. The UK Government said the incident did not pose a risk to the wider energy system.
The National Cyber Security Centre (NCSC) is understood not to have received reports of outages from regulated power station operators.
A spokesperson for the DESNZ said: “This story refers to an incident impacting a small-scale energy generator, and at no point was there a risk to the wider energy system.
“The UK has a highly resilient energy system. We work closely with the energy sector to protect infrastructure and ensure the highest security standards.”
The incident comes amid growing concerns over state-backed cyber threats to the UK’s critical infrastructure. NCSC Chief Executive, Richard Horne, has previously warned that countries including Russia, China and Iran are increasingly targeting systems supporting essential services.
Iran has faced repeated allegations of cyber-attacks against infrastructure overseas. US security agencies also warned earlier this year of threats from Iran-linked groups targeting critical infrastructure.
The latest incident highlights concerns over the vulnerability of smaller energy facilities to cyber threats.
