Russian hackers have stolen records covering 300m patient interactions with the NHS, including the results of blood tests for HIV and cancer.
Seven hospitals run by two NHS trusts were affected by the attack, which targeted Synnovis, a private/NHS joint venture that provides pathology services such as blood tests and transfusions. It is unclear at this stage if the hack involves only hospitals in the trusts or is more widespread.
