Kaiser Permanente Discloses Data Breach at WA Health Plan, 69K Impacted
Kaiser Foundation Health Plan of Washington, Virginia Mason Medical Center, and MCG Health recently reported data breaches impacting protected health information (PHI).
Kaiser Permanente notified 69,589 individuals of a data breach that occurred at the Kaiser Foundation Health Plan of Washington. According to a notice on its website, Kaiser Permanente discovered on April 5 that an unauthorized party had gained access to an employee’s emails.
Kaiser Permanente terminated the access “within hours” and began investigating. Although there was no indication that the unauthorized party accessed the protected health information (PHI) contained in the emails, the organization could not rule out the possibility.
The emails contained names, dates of service, medical record numbers, and laboratory test result information.
“After discovering the event, we quickly took steps to terminate the unauthorized party’s access to the employee’s emails,” the notice emphasized.
“This included resetting the employee’s password for the email account where unauthorized activity was detected. The employee received additional training on safe email practices, and we are exploring other steps we can take to ensure incidents like this do not happen in the future.”
Kaiser Permanente began notifying impacted patients by mail on June 3.
Virginia Mason Medical Center Faces Second Breach Since December
Virginia Mason Medical Center (VMMC) faced its second data breach since December 2021, according to a notice on its website. In the latest incident, an external third party “intruded” three servers between January 16 and January 20, 2022.
There was no evidence of data exfiltration, but the servers potentially contained PHI, including names, phone numbers, Social Security numbers, health insurance numbers, email addresses, COVID-19 screening and surveillance, and presence on a COVID-19 vaccine waiting list. The incident impacted 1,523 individuals.
“VMMC conducted a comprehensive investigation of the incident. The FBI was notified as well. Upon discovery, the involved servers were quickly removed from the network. The involved servers were isolated for investigation and subsequently will no longer be used,” VMMC’s notice stated.
“New servers containing updated security and software were put in place. The forensic vendor, and other partners, reviewed each file that the unauthorized party may have accessed to determine what, if any, personal or protected health information was present.”
In March 2022, VMMC also notified patients of a separate data breach that impacted just under 3,000 individuals. An unauthorized party accessed some VMMC staff email accounts between December 21, 2021, and January 3, 2022, via a phishing attack. VMMC said it implemented blocks to the phishing domain and provided further employee education.
“VMMC regrets this event and any concern it may cause,” both notices stated.
“We strive to always maintain the privacy and security of our patients’ and employees’ protected information.”
