Privacy Incident

NASCO, a third-party provider of benefits administration services to health plans, used a third-party software application, MOVEit Transfer by Progress Software (“MOVEit”), to exchange files. On May 30, 2023, NASCO experienced a data security incident, due to a previously unknown vulnerability in MOVEit, in which a threat actor acquired data from NASCO’s MOVEit server. When NASCO learned of this incident on July 12, 2023, it promptly took steps to secure its systems, notified law enforcement authorities, and launched an investigation that found that some of the acquired files contained the personal information of certain health plan members. NASCO is providing notification to impacted individuals and offering them 24 months of complimentary enrollment in Experian®’s identity monitoring services.
