    • If other, please specify: Milliman Solutions provides risk assessment services to clients including life insurance companies. As part of those services, Milliman Solutions utilizes a third-party vendor, Pension Benefit Information, LLC (“PBI”), to conduct research on whether consumers have passed away. For that purpose, Milliman Solutions transferred data regarding its clients’ consumers to PBI utilizing a secure and encrypted file transfer protocol. PBI recently notified Milliman Solutions that PBI experienced a data security incident affecting the data of Milliman Solutions’ clients. Specifically, PBI disclosed that it utilized the “MOVEit Transfer” software provided by Progress Software Corporation (“Progress Software”) for PBI’s secure file transfer protocol (“SFTP”) servers. PBI also indicated that it stored Milliman Solutions’ clients’ data on PBI’s SFTP servers utilizing the MOVEit Transfer software. According to information provided to Milliman Solutions by PBI, on or around May 31, 2023, Progress Software disclosed for the first time that its MOVEit Transfer software contained a previously unknown, “zero-day” vulnerability that could be exploited by an unauthorized actor (CVE-2023-34362). PBI also disclosed that it launched an investigation into the nature and scope of the MOVEit vulnerability’s impact to PBI’s systems. According to PBI, its investigation determined that an unauthorized third party accessed one of PBI’s MOVEit Transfer servers on May 29, 2023, and May 30, 2023, and downloaded data. PBI explained it then conducted a manual review of its data to confirm the identities of individuals potentially affected by this event. PBI completed that review on June 16, 2023, and confirmed to Milliman Solutions at that time that the personal information of certain consumers of Milliman Solutions’ clients were affected and Milliman Solutions, following reconciliation of the data, was able to recently inform its clients of the scope of individuals whose information may have been affected. The Milliman Solutions clients whose consumer data was affected by the incident include MEMBERS Life Insurance Company (MLIC), CMFG Life Insurance Company (“CMFG”), and The Independent Order of Foresters (“Foresters”).
