The British Library may have to spend £7million of its reserves to recover from a crippling cyber attack, according to reports.
Criminals knocked out the website of the UK’s national library used by over 11m people a year in October.
Hackers from the Rhysida group also published hundreds of thousands of stolen files online, including customer and personnel data, after bosses refused to pay a £600,000 ransom.
A spokesman said: “The final costs of recovering from the recent cyber attack are still not confirmed.
