A ransomware attack on Synnovis, a London-based medical testing provider, has severely disrupted pathology services at major NHS hospitals.

The attack impacted critical operations such as blood transfusions and transplant surgeries at King's College Hospital and Guy's and St Thomas'.

The incident has led to the cancellation of healthcare procedures and the redirection of patients, although emergency services remain available.

Synnovis is collaborating with cybersecurity authorities to minimize disruptions and ensure patient services are maintained.

An investigation is ongoing to assess the impact of the attack.

This is the third attack on Synlab group in a year, underscoring the urgent need for enhanced cybersecurity measures in healthcare infrastructure.
