London hospitals cancel operations, appointments after ransomware attack

Several London hospitals said Tuesday that they had to cancel operations and send patients away because of a cyberattack on a company that supplies pathology laboratory services.

The firm, Synnovis, said it had been hit with a ransomware attack. Chief Executive Mark Dollar said the attack has affected all Synnovis IT systems, resulting in interruptions to many of our pathology services.

It is still early and we are trying to understand exactly what has happened, he said.
