Earlier this week, the Guardian newspaper published the results of a lengthy investigation in which it accused the organisation's senior management of having "consistently covered up" the scale of the intrusions, which it is claimed date back to 2015.
A spokesperson for Sellafield Ltd said: "We have no records or evidence to suggest that Sellafield Ltd networks have been successfully attacked by state-actors in the way described by the Guardian. Our monitoring systems are robust and we have a high degree of confidence that no such malware exists on our system.
However, this is not the first time that evidence of cyber intrusions affecting Sellafield have come to light. In 2021, for example, the Information Commissioner's Office fined Sellafield Ltd £320,000 for a data breach that occurred in 2017.
