Largest Healthcare Data Breaches in February 2019

The largest healthcare data breach reported in February involved the accidental removal of safeguards on a network server, which allowed the protected health information of more than 973,000 patients of UW Medicine to be exposed on the internet. Files were indexed by the search engines and could be found with simple Google searches. Files stored on the network server were accessible for a period of more than 3 weeks.

The second largest data breach was due to a ransomware attack on Columbia Surgical Specialist of Spokane. While patient information may have been accessed, no evidence was found to suggest any ePHI was stolen by the attackers.

The 326,629-record breach at UConn Health was due to a phishing attack that saw multiple employees’ email accounts compromised, and one email account was compromised in a phishing attack on Rutland Regional Medical Center that contained the ePHi of more than 72,000 patients.
