Incident marks apparent escalation by Tehran in its in retaliation against UK over allowing US to use British bases
Hackers linked to Iran have been blamed for a cyber-attack that caused a British power plant to be temporarily shut down.
The incident involved a small-scale energy generator, according to the UK government, which said that at no point was there a risk to the wider energy system.
However, it marks an apparent escalation in the threat posed by Iran after the UK said it had given permission for the US to launch “defensive” operations against Tehran from British bases.The power plant was shut down for four days as a result of the attack last month, according to the Sunday Telegraph, which first reported it.
A spokesperson for the Department for Energy Security and Net Zero 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 National Cyber Security Centre (NCSC), which deals with attacks on critical infrastructure, is understood not to have received any reported outages from regulated operators of power stations.
The Conservatives said the incident reflected a “new kind of warfare”, which meant Britain needed to prioritise “cheap, reliable energy”. “The world is getting more dangerous, which is why we need to prioritise our energy security,” said Claire Coutinho, the Conservative spokesperson on energy.
“Leaving ourselves reliant on imports of gas and electricity and failing to build enough reliable gas or nuclear plants for backup at home, all leaves us more vulnerable.”
Hostile states such as Russia, China and Iran are increasingly targeting systems behind the UK’s key services, according to a warning this year from Richard Horne, the NCSC’s chief executive.
The government said last month the UK was “ready to defend itself” after Iran’s military warned any bases being used by the US were “legitimate targets”.
