The hospital authorities said it was in the process of reevaluating its downtime capabilities and might have to reschedule certain appointments. It added that affected patients will be contacted accordingly.

The attack prompted primary care services to remain closed. Security experts worked to assess the extent of the damage and find a resolution.

As the investigation continues, the FBI and other law enforcement agencies are collaborating with the victim entities to identify the perpetrators and secure data.
