Biggest Healthcare Data Breaches Reported in January 2021

The breach reported by Florida Healthy Kids Corporation was one of the biggest healthcare data breaches ever. The breach was reported by the healthcare plan, but actually took place at one of its business associates. The health plan contracted an IT company for hosting its website and an application for applications for insurance coverage. The company did not implement patches for seven years, which allowed a hacker to gain access to sensitive data.

Hendrick Health had a major data breach as a result of a ransomware attack; one of many reported by healthcare delivery organizations  since September 2020 when ransomware actors increased their attacks on the healthcare sector. The County of Ramsey breach was also due to a ransomware attack at one of its technology partners.

Email-based attacks such as business email compromise (BEC) and phishing attacks were prevalent during January, and were the cause of 4 of the top ten breaches.
