A ransomware attack on pathology services provider Synnovis on June 3 has severely impacted several London hospitals, affecting the care of two million people. This cyberattack has forced hospitals to declare a critical incident, cancel cancer surgeries, and halt blood transfusions. The National Health Service (NHS) is now urgently calling for donations of O positive and O negative blood, as the disruption has impaired their ability to match patients with the correct blood type. NHS England’s National Medical Director, Stephen Powis, emphasized the critical need for blood donations to help hospitals continue treating patients effectively during this crisis. Ransomware attacks, which encrypt and disable a victim’s computer systems until a ransom is paid, pose significant risks to healthcare providers due to their potential to disrupt life-saving treatments. Cybersecurity expert Steve Waterhouse highlighted the dire consequences, noting that delays in medical care caused by these attacks can be life-threatening. This incident, suspected to be carried out by the Russian-speaking Qilin group, underscores the urgent need for robust cybersecurity measures across all sectors. Synnovis is cooperating with law enforcement, but experts warn that such attacks are becoming increasingly common, emphasizing the importance of preparedness and resilience against cyber threats.
