The official filing, dated March 6, 2026, confirms that unauthorized parties gained access to a network where confidential client records were stored.

While the specific categories of information involved were not detailed in the public record, the company's filing indicates that personal information was compromised. This exposure raises significant concerns for the security of affected clients' data.

The unauthorized access to this personal information creates potential risks for those impacted. These risks can include identity theft, various financial frauds, and targeted phishing schemes where malicious actors attempt to gain further sensitive details by impersonating legitimate entities.

Because certain types of exposed information are permanent and cannot be easily changed, affected individuals may face long-term security considerations regarding their financial privacy. The company stated that this incident is currently under investigation.
