Thundermist Health Center in Woonsocket, R.I., was victimized by a ransomware attack that disrupted its systems on Thursday morning.

Amanda Barney, associated VP of communications and development said that the health care center acted promptly to protect patient and employee data, local news affiliate WPRI reported. As of Thursday evening, there is no evidence that any information was compromised, Barney added.

"We acted quickly to protect patient data, limit the attack and continue to provide safe patient care. Patient and employee information was not compromised. We are open and there was little impact to patient care," said a statement on the center's home page. "We started our emergency plan. We cancelled appointments that could not be safely completed without access to our electronic health record. We contacted the Rhode Island Department of Health and Rhode Island State Police."

Thundermist serves tens of thousands of patients each year in the communities of Woonsocket, West Warwick and South County.
