Cyberattack disrupts operations in hospitals and clinics operated by Prospect Medical Holdings
08/09/2023 / By Laura Harris
Connecticut, Pennsylvania, Texas, Rhode Island and California are reeling from a widespread cyberattack that has crippled computer systems in hospitals and clinics operated by Prospect Medical Holdings, causing disruptions in emergency services and patient care.
John Riggi, an expert in cybersecurity and risk advisory for the American Hospital Association, emphasized the extent of the breach as hospitals resort to paper-based systems and manual processes.
“These are threat-to-life crimes, which risk not only the safety of the patients within the hospital but also risk the safety of the entire community that depends on the availability of that emergency department,” Riggi stated.
Prospect Medical Holdings, which is based in California and has operating facilities in Texas, Connecticut, Rhode Island and Pennsylvania, has taken its systems offline to protect against further damage. The company has launched an investigation with the assistance of third-party cybersecurity specialists, though the recovery process could last for weeks.
Meanwhile, the White House is closely monitoring the situation, with the National Security Council providing oversight. The Department of Health and Human Services has also offered federal support to prevent disruptions in patient care.
While the Federal Bureau of Investigation (FBI) in Connecticut is collaborating with law enforcement partners and victim entities, officials have yet to confirm whether the attack is a case of extortive ransomware. Ransomware attacks involve criminals stealing sensitive data, activating encryption malware to paralyze systems, and demanding ransoms.

Furthermore, experts have warned against paying ransoms, citing the risks of encouraging criminal behavior and the potential sale of stolen data on the dark web.
Several states deal with the aftermath of the cyberattack
As a result of the attack, emergency departments in several states faced closures, and patients had to be redirected to alternative medical centers.
In Connecticut, the emergency departments at Manchester Memorial and Rockville General Hospitals were forced to shut down on August 3. Several patients were diverted to alternative medical centers. The Eastern Connecticut Health Network, which manages many of the Connecticut facilities, reported the suspension of elective surgeries, outpatient appointments and blood drives.
Healthcare services in Pennsylvania, including Crozer-Chester Medical Center in Upland, Taylor Hospital in Ridley Park, Delaware County Memorial Hospital in Drexel Hill and Springfield Hospital in Springfield, were also affected by the attack. Medical staff scramble to manage the situation as patients faced uncertainties in the suspension of elective surgeries, outpatient appointments, and other essential services.
Even the Lone Star State was not immune to the far-reaching consequences of the cyberattack. Patient care was compromised as the facilities struggled to restore computer systems and the seamless coordination of medical services was disrupted.
In Rhode Island, the cyberattack cast a long shadow over healthcare facilities, creating chaos in emergency rooms and forcing primary care services to a standstill. The disruptions in the state exemplified the interconnectedness of the healthcare system, where a single cyber incident can trigger a domino effect.
In California, seven hospitals in Los Angeles and Orange counties were directly impacted. The attack not only disrupted patient care but also highlighted the extent of the vulnerability of critical healthcare infrastructure.
