Cyberattack disrupts hospital systems across U.S.

August 9, 2023

A cyberattack has disrupted hospital systems across the United States, forcing healthcare facilities to halt operations, reschedule appointments, and divert ambulances.

The attack impacted all healthcare facilities dependent on Prospect Medical Holdings’ hospital systems, which operates out of California and has several hospitals and numerous clinics there and in Texas, Connecticut, Rhode Island, and Pennsylvania.

In Connecticut, the emergency departments at Manchester Memorial and Rockville General Hospital were closed, and patients were diverted to other nearby medical centers. The cyber attack also impacted primary care services at Waterbury Hospital, forcing the facility to reschedule appointments and resort to manual systems.

The Eastern Connecticut Health Network (ECHN), which runs Prospect’s facilities in 19 towns in the region, indefinitely suspended surgery and GI procedures, outpatient medical imaging, outpatient blood draw, urgent care, and wound care.

The cyber attack also impacted several facilities in Pennsylvania, including the Crozer Chester Medical Center, Taylor Hospital in Ridley Park, Delaware County Memorial Hospital, and Springfield Hospital.

Prospect Medical Holdings has yet to disclose the nature of the cyber attack, but medical officials in Pennsylvania revealed it was a ransomware attack.

Prospect has not given a timeline for restoring impacted hospital systems, but the process could take weeks. Meanwhile, no ransomware group has publicly taken responsibility for the attack on Prospect’s hospital systems.
