Investigation into cyber attack ‘could take weeks’, says NHS England

Investigations into a cyber attack on London hospitals will take several weeks to be completed, according to NHS England. The ransomware attack targeted NHS provider Synnovis, with hundreds of operations and appointments cancelled as a result, while some patients may have to repeat tests. Authorities are now working to verify the data stolen by the Russian group Qilin and published online. Experts anticipate the disruption caused by the attack will last for several months.
