Louisville, Ky.-based Norton Healthcare confirmed that the May ‘cyber incident’ that led the health system to shut down its network briefly was a ransomware attack.
After an investigation, the health system concluded that the unauthorized party had access to certain network storage devices between May 7 and May 9. However, the health system found no evidence that the attackers accessed its EHR or MyChart system, according to a Dec. 8 Norton Healthcare news release.
The health system is offering two years of free credit monitoring services to affected individuals.
