Many schools and universities received benefits for university staff retirement through the Teachers Insurance and Annuity Association of America ("TIAA"). The TIAA portion of the intrusion did not directly target the vendor's computer systems. Pension Benefit Information, TIAA's vendor, informed TIAA that the intrusion had affected PBI. PBI informed HHS that 1,209,825 patients or insurance holders of its HIPAA-covered clients had been impacted, while Milliman Solutions informed the Maine Attorney General's Office that the attack on PBI had affected 1,280,823. At CalPers, Genworth Financial, and Wilton Reassurance, an estimated extra 5 million people have been impacted, according to earlier press reports. Even yet, they do not represent an exhaustive list or an estimate of all the clients of PBI whose consumers were impacted. They took it seriously and took preventive steps to secure it. PIB also offered access to 24 months of complimentary identify monitoring services through Kroll.

The California Office of the Attorney General reported a data breach involving CalPERS on June 22, 2023. The breach occurred on May 29, 2023, and was due to a zero-day vulnerability in the MOVEit Transfer application used by the third-party vendor PBI Research Services, potentially exposing personal information of retirees, including names, dates of birth, and Social Security Numbers.
