COLUMBUS — Columbus Surgery Center and Eye Physicians were the target of a ransomware attack that may have resulted in the disclosure of patients' personal and health information.
The businesses, both located at 3772 43rd Ave., initiated a comprehensive response to secure their systems and investigate what was called a “data security incident," according to press releases.
Letters sent Thursday to people whose information may have been compromised include information on steps they can take following the attack.
According to the releases, the cyberattack occurred on Oct. 7.
The businesses used independent computer forensics experts to determine how the incidents occurred and if information had been accessed by an unauthorized third party.
The investigation did not identify any evidence of access to patient information, but the possibility exists that patients' names, dates of birth and medical procedure notes are at risk. No Social Security numbers, financial transactions or payment information were involved in the incident. To date, there has been no known misuse of anyone’s information as a result of the incident.
To prevent similar events from occurring in the future, the businesses had an in-depth network security assessment completed by an outside security consultant and improved hardware and software.
Toll-free call centers have been created to answer questions about the incident and related concerns. The centers are available 8 a.m.-8 p.m. Monday-Friday and can be reached at 855-575-7460 for Columbus Surgery Center and 844-324-7572 for Eye Physicians.
