'Some data leaked' after cyber-attack on The British Library

The British Library has continued to face a "major technology outage" caused by a cyber-attack that has also led to leaked data.

The library’s website, online systems and services are still being affected a month on from the attack, as are some onsite services like its Reading Rooms and public wifi, while the library’s London and Yorkshire sites are open. In a statement, the British Library said that it expects various services to be functioning again "in the next few weeks", but added that disruption to others may last longer than this.

"We have now confirmed that this was a ransomware attack, by a group known for such criminal activity," the statement explained. "We are aware that some data has been leaked, which appears to be from files relating to our internal HR information."

While there is no evidence that wider user data has been affected, the library has suggested that users change any passwords they use both for the library’s services and to log onto other websites.

"We have taken targeted protective measures to ensure the integrity of our systems, and we continue to undertake an investigation with the support of the National Cyber Security Centre (NCSC), the Metropolitan Police and cybersecurity specialists," the statement added.

The British Library’s chief executive, Sir Roly Keating, said: “We are immensely grateful to our many users and partners who have shown such patience and support as we work to analyse the impact of this criminal attack and identify what we need to do to restore our online systems in a safe and sustainable manner. It is too soon to offer an exact timetable, but we will provide regular updates as we progress this vital work.”
