Investigation of Russian hack on London hospitals may take weeks amid worries over online data dump

A ransomware attack on London hospitals earlier this month led to the cancellation of hundreds of operations and appointments, with the investigation slated to take several weeks. The National Health Service (NHS) confirmed that patient data related to the attack had been published online, reportedly including names, date of birth, and descriptions of blood tests. The Russian group, Qilin, is believed to be behind the attack — the same group that disrupted services across NHS hospitals in 2017.
