A cyberattack has been reported against Prospect Medical Holdings. This healthcare organization, which operates in California, Texas, Pennsylvania and Connecticut, as well as Rhode Island, was reportedly targeted.
A so-called data security incident began on Thursday and caused some services to be delayed, including elective surgery and outpatient appointments.
As part of its investigation into the digital breach, the FBI in Connecticut works with “law-enforcement partners and victim entities”.
Cyberattack disrupted hospital computers in several states. Some emergency rooms were closed and ambulances diverted. Many primary care services remained shut on Friday while security experts tried to identify the extent of the issue and fix it.
The “data-security incident” started Thursday at facilities operated Prospect Medical Holdings. This company is based out of California, and operates hospitals and clinics in California, Texas, Connecticut and Rhode Island, as well as Pennsylvania.
The company released a statement on Friday saying that “we took our systems off-line to protect them, and we launched an investigation with third-party cybersecurity experts.” While our investigation is ongoing, we remain focused on the urgent needs of our patients and work to restore normal operations as soon as possible.
The emergency departments of Manchester Memorial Hospital and Rockville General Hospital were closed on Thursday for a large part and patients were sent to other medical centers nearby.
Jillian Menzel said, “We have a Prospect team that is working on evaluating the impact the attack has had on all organizations,” in a press release.
The FBI in Connecticut released a statement stating that it was working with “law-enforcement partners and victim entities”, but couldn’t comment on an ongoing investigation.
Eastern Connecticut Health Network which operates the facilities reported that elective surgeries, outpatient appointment, blood drives, and other services had been suspended. While the emergency rooms reopened on Thursday evening, many primary care clinics were closed Friday. According to the website of the Eastern Connecticut Health Network, patients were contacted one-by-one.
Similar disruptions were also reported at other sites system-wide.
In a press release, Lauresha Xhihani said that Waterbury Hospital was following downtime procedures including using paper records until the problem is resolved. “We’re working with IT experts to fix it as soon as possible.”
