In April, hackers breached the IT network of CentroMed, a healthcare provider based in San Antonio, Texas, compromising the protected health information of 400,000 patients.
On May 1, CentroMed said it detected unusual activity in its IT network. This prompted the healthcare organization to launch an investigation into the incident.
Through the investigation, CentroMed learned that an unauthorized party accessed its IT network on April 30 gaining access to files that contained former and current patients' information.
Names, addresses, dates of birth, Social Security numbers, financial account information, medical records numbers, health insurance information, diagnosis and treatment information and claims data may have been involved, according to a press release from CentroMed.
CentroMed said it began notifying all affected individuals on May 17.
