Hundreds of thousands of sensitive NHS documents, some relating to British and foreign Royals, senior judges and members of the House of Lords, have been stolen by Russian hackers, The Mail on Sunday can reveal.
The unprecedented data breach, one of the largest to hit the health service, has seen 169,000 confidential documents dumped on the dark web after the ransomware gang exploited a bug in software provided to NHS bodies by US tech giant Oracle.
Many of those affected by the leak are high-profile NHS private patients – with some invoicing details from Barts NHS Health Trust in London linked to unnamed patients from royal residences including King Charles’s official home Clarence House, Buckingham Palace, Sandringham and Windsor Castle.
It is unclear which Royals were treated and for what purpose but the leak raises serious concerns about the security of medical details of the Royal Household as the King continues to be treated for an undisclosed form of cancer.
The grave incident also casts doubt over controversial plans to introduce digital ID systems in the UK as Oracle’s billionaire owner, Larry Ellison, is the biggest donor to the Tony Blair Institute, which is lobbying for such systems to be introduced. Others affected by the breach include the BBC, Premier League football clubs, British aristocrats, a member of the Bahraini Royal Family and billionaire business moguls.
The files, which have been seen by the MoS, also include data linked to children being treated at NHS hospitals, women undergoing fertility treatment and patients receiving kidney dialysis.
The extraordinary breach comes after cybersecurity experts warned in October that the Oracle software used by the NHS and the Treasury – which provides financial management and HR support to organisations – was vulnerable to Russian hackers, and that attempts at ‘exploitation’ were ‘highly likely’.
Researchers at Google said hackers from a gang known as Clop had sent emails to executives at ‘numerous organisations… alleging the theft of sensitive data’ and demanding money for its safe return.
