Hacked London NHS hospitals data allegedly published online

Cyber-attack earlier this month led to cancellation of almost 1,600 operations and outpatient appointments

Data from a ransomware attack has allegedly been published online weeks after the attack halted operations and tests in major London hospitals, NHS England has said.

A Russian group carried out the cyber-attack on Synnovis, a private pathology firm that analyses blood tests for Guy's and St Thomas' NHS foundation trust (GSTT) and King's College trust, on 3 June, forcing hospitals in the capital to cancel almost 1,600 operations and outpatient appointments.
