The UK’s most hazardous nuclear site, Sellafield, has been hacked into by cyber groups … the Guardian can reveal.

The astonishing disclosure and its potential effects have been consistently covered up by senior staff at the vast nuclear waste and decommissioning site, the investigation has found.

The Guardian has discovered that the authorities do not know exactly when the IT systems were first compromised. But sources said breaches were first detected as far back as 2015, when experts realised sleeper malware – software that can lurk and be used to spy or attack systems – had been embedded in Sellafield’s computer networks.

…

The full extent of any data loss and any ongoing risks to systems was made harder to quantify by Sellafield’s failure to alert nuclear regulators for several years, sources said.

The revelations have emerged in Nuclear Leaks, a year-long Guardian investigation into cyber hacking, radioactive contamination and toxic workplace culture at Sellafield.

The site has the largest store of plutonium on the planet and is a sprawling rubbish dump for nuclear waste from weapons programmes and decades of atomic power generation.

…

In one highly embarrassing incident last July, login details and passwords for secure IT systems were inadvertently broadcast on national TV by the BBC One nature series Countryfile, after crews were invited into the secure site for a piece on rural communities and the nuclear industry.
