Top kidney dialysis firm hit by damaging ransomware attack

• DaVita confirms ransomware attack in new SEC form
• It was forced to shut down parts of its infrastructure to remedy
• The scope of the attack is not fully known yet

DaVita, a major American healthcare company specializing in kidney care, has suffered a ransomware attack that forced it to temporarily suspend parts of its operations.

In a new 8-K form filed with the US Securities and Exchange Commission (SEC), DaVita said that in mid-April 2025, it became aware of a “ransomware incident” that encrypted certain elements of its network.

“Upon discovery, we activated our response protocols and implemented containment measures, including proactively isolating impacted systems,” the company said, adding that it is currently working to assess and remediate the incident, and that it has brought third-party cybersecurity experts to assist.
