HARTFORD, Conn. (WTNH) – During the summer, multiple Connecticut hospitals and clinics owned by Prospect Medical Holdings were impacted by a six-week cyber attack from July to August.

The multi-state data breach impacted Manchester Memorial Hospital, Rockville General Hospital and Waterbury Hospital.

The Federal Bureau of Investigation (FBI) got involved, and the White House monitored the situation.

The above video is from the 5 p.m. newscast on (11/15/2023).

News 8 learned 109,728 people in Connecticut may have had their data compromised in the incident, according to a two-page letter sent to Connecticut Attorney General William Tong by lawyers representing Prospect Medical Holdings.

The letter by a Partner at Baker & Hostetler LLC can be read in part below.

“As you are aware, on August 1, 2023, Prospect Medical learned of a data security incident that disrupted the operations of some of its Information Technology (“IT”) systems. Prospect Medical immediately took steps to secure its systems, contain the incident, and notify law enforcement. Additionally, a third-party forensic firm was engaged to conduct an investigation.”

News 8 learned that information on patients’ names, addresses, dates of birth, diagnoses, lab results, medications, insurance, and financial data may have been compromised.  

Those whose social security number or driver’s license information was involved in the cyber attack are offered two years of complimentary credit monitoring and identity protection services through IDX.

“This is a common undertaking for companies affected by a data breach. We saw it with Equifax, for example: Two years of credit monitoring. It’s helpful, but I don’t have to tell you it doesn’t solve the whole problem, not even close,” Tong said.

Prospect Medical Holdings has added more security measures to monitor its systems to help prevent a cyber attack from happening again.

The letter goes on to say that Prospect Medical Holdings has also established a phone line to answer any questions people may have on the data breach.
