SEI009091825
The Maine Office of the Attorney General disclosed on July 8, 2022, that SEI-Group Holdings, LLC suffered a data breach between March 24, 2022, and April 16, 2022, affecting 2,080 individuals, including at least one Maine resident. The incident, identified on June 10, 2022, resulted from an external system breach (hacking), potentially exposing names, Social Security numbers, and financial account information of victims. In response, SEI-Group is providing 24 months of credit monitoring and identity protection services via Experian to impacted individuals. The compromised data—particularly financial and personally identifiable information (PII)—poses significant risks, including identity theft, financial fraud, and long-term reputational harm for the company. The breach underscores vulnerabilities in SEI-Group’s cybersecurity defenses, raising concerns about third-party attacks targeting sensitive customer data.
