The investigation focuses on confirming the exact scope of the compromised data. According to the firm's report, the exposed information includes Full Name, Social Security Number, Date of Birth, Financial Account Number, Routing Number, Tax Return Information, Investment and Portfolio Details, Mailing Address, Email Address, and Phone Number.

The occurrence of a breach of this magnitude raises critical questions regarding the adequacy of the firm's administrative, physical, and technical safeguards designed to protect client data from unauthorized access or exfiltration.
