Overview

A cyberattack on NHS pathology provider Synnovis left patients at serious risk after 3,000 consultations or operations were cancelled because of the hack. Those affected included cancer patients in urgent need of medical care. As well as the cancelled operations, affected patients were left at risk of fraud, scams and ID theft. 

Multiple London hospitals were affected by the breach and tens of thousands of NHS patients had their sensitive data published online by hackers. One cyber security expert said the violation was “one of the most significant and harmful cyber attacks ever in the UK.”
