Ransomware Attack Leaves London Hospitals Desperate for O Positive and O Negative Blood Donors
NHS Blood and Transplant has issued an urgent call for O Positive and O Negative blood donors after a cyberattack on Synnovis disrupted London hospitals. Due to the attack, blood type matching systems are down, leading to a critical shortage of these blood types.

Hot Take:
Who knew ransomware could suck the lifeblood out of hospitals quite literally? It’s time for us to roll up our sleeves and save the day—because hackers certainly won’t!
Key Points:
- Ransomware attack on Synnovis disrupts operations at multiple NHS hospitals in London.
- NHS issues urgent call for O Positive and O Negative blood donors.
- Non-urgent procedures canceled or redirected due to blood transfusion complications.
- O Negative and O Positive blood types are being used as a safety measure.
- Synnovis has no clear timeline for system recovery.
