DaVita, a major player in the kidney dialysis industry, has been targeted by a ransomware attack.
No impact on patient-related services has been reported so far, but if the stolen data is released or sold, it may lead to phishing attacks and identity theft.
Ransomware attacks have evolved into a double extortion model, where attackers not only encrypt files but also steal sensitive data.
To protect against data extortion, organizations should backup and encrypt data, implement access control measures, maintain robust endpoint protection, configure firewalls correctly, train staff on cybersecurity, and practice safe application practices.
