The confirmed data exposure includes highly sensitive categories such as Full Name, Social Security Number, Date of Birth, Financial Account Number, Routing Number, Tax Identification Information, Investment and Portfolio History, and Mailing Address. The aggregation of such comprehensive financial and identity data creates a severe risk for affected individuals, potentially enabling sophisticated financial fraud, unauthorized account access, and long-term identity theft.
