MaineGeneral breach update: investigation revealed additional PHI compromised

There’s an update to a breach reported by MaineGeneral Health in December after the FBI alerted them in November that information had been found on an external web site. At the time of their December notification, MG had noted that the scope of the incident was still under investigation.

Today, they issued a press release with an update. It reads, in part:

… MaineGeneral has determined additional protected health information impacting some individuals may have been accessed by the attacker. Letters to those impacted are being sent today, explaining the stage of the investigation, and ways individuals can protect themselves – including access to free credit monitoring and identity restoration services MaineGeneral is offering to those receiving letters of notification.

Information Compromised

While the FBI’s investigation continues, MaineGeneral’s investigation is nearing completion and the forensic team has determined that certain protected health information on its network was or may have been subject to unauthorized access on or about September 11 and 12, 2015, including:

  • The following information relating to patients referred for radiology services since June of 2009: name, address, date of birth, demographic information, medical information including name of referring physician and allergy information, Social Security number, medical insurance information, medical record number, emergency contact information, guarantor information, and employer information.
  • The names, Social Security numbers, addresses, phone numbers, attending physician name, account number and age of certain patients in a patient advocacy file.
  • The names, Social Security numbers, dates of birth, addresses, medical record numbers, treatment information, and health history information of certain patients in a patient diagnostic registry file.
  • The names and addresses of certain patients, on a mailing list file related to a physician departure in October 2010.
  • The names, addresses, dates of birth, Social Security numbers, and medical identification numbers of certain patients in a monitoring system file.
  • The name, address, procedure date, procedure description, diagnosis and treatment choice of a patient in a letter to the patient.
  • The names, addresses and telephone numbers of certain employees.
  • The names, addresses and telephone numbers of certain prospective donors.

However, the information detected by the FBI on the external website was limited to the date of birth and emergency contact name, address, and telephone number for certain patients referred to MaineGeneral Medical Center for radiology services since June 2009, the names, addresses, and telephone numbers of certain employees, and the names, addresses, and telephone numbers of certain prospective donors. The data detected by the FBI on the external website does not contain Social Security numbers, patient names, patient medical or health insurance information, health records, driver’s license numbers, or credit/financial account information.

More information, including the full statement, is available on MaineGeneral’s website.
