LONDON - After The Guardian news outlet released an article claiming that the Sellafield nuclear site had been cyber-attacked by state actors mostly linked to Russia and China, the British government released a statement saying that the claims were false and that they have no records or evidence to suggest that Sellafield Ltd networks had been attacked by state-actors "in the way described by the Guardian".

The statement added that the agency is "confident that no such malware exists" on their system.

The Guardian report claimed that the site was infected by sleeper malware that had been detected as far back as 2015, but said that the authorities don't know when it was first compromised, and it is not known if the malware has been eradicated.

"It may mean some of Sellafield’s most sensitive activities, such as moving radioactive waste, monitoring for leaks of dangerous material, and checking for fires, have been compromised," the report stated. 

"The astonishing disclosure and its potential effects have been consistently covered up by senior staff at the vast nuclear waste and decommissioning site," The Guardian report said.
