Montefiore Notifies Patients About Security Breach & Potential Identity Theft

Montefiore Medical Center announced on January 29, 2021 that it is notifying some patients about a security breach involving information illegally accessed by a former employee.

Categories of personal information accessed varied and may include first and last names, medical record numbers, addresses, dates of birth and the last 4-digits of Social Security numbers. Some clinical information, such as test results, diagnoses, and visit histories, may have also been inappropriately accessed. There is no evidence that financial information, including credit card numbers, were accessed, or that patient information was used for identity theft.

The incident occurred between June 2020 and November 2020. Upon learning of this situation, Montefiore immediately deactivated the employee’s access to the electronic medical record system. After a thorough investigation, the employee was fired and the case was referred to law enforcement for possible criminal prosecution.

“We apologize for any inconvenience to our patients that this breach has caused,” said Robert Dalrymple, Chief Information Security Officer, Montefiore Medical Center. “We are taking steps to implement additional safeguards to strengthen the security of our systems.”
