PharMerica provides its services to senior living communities, nursing facilities, public health organizations and post-acute care organizations.
“On March 14, 2023, we learned of suspicious activity on our computer network. Upon discovering the cybersecurity incident, we promptly began an internal investigation and engaged cybersecurity advisors to investigate and secure our computer systems.” reads the letter sent to the impacted individuals and shared with the Maine Attorney General’s Office. “The investigation determined that an unknown third party accessed our computer systems from March 12-13, 2023, and that certain personal information may have been obtained from our systems as a part of the incident.”

- “If an application is made for credit, please notify the following person(s): (e.g., list a surviving
relative, executor/trustee of the estate, and/or local law enforcement agency – notifying the
relationship).”
Who is behind the attack?
