Hospitals across England have been hit by a large-scale cyber-attack, the NHS has confirmed, which has locked staff out of their computers and forced many trusts to divert emergency patients.Hospitals across the country appear to have been simultaneously hit, with a pop-up message demanding a ransom in exchange for access to the PCs. NHS Digital said it was aware of the problem and would release more details soon. Details of patient records and appointment schedules, as well as internal phone lines and emails, have all been rendered inaccessible.

The problem appears to be limited to Windows PCs. Macintosh, Linux, and various mobile tablets appear to be unaffected.
