Centennial Bank (including its division Happy State Bank) data breach

Clerk's notes

Centennial Bank, which operates across Texas and includes its division Happy State Bank, formally reported a data security incident to the Texas Attorney General's office on September 17, 2026. The institution indicated that the breach event took place on or around August 7, 2026, impacting its robust financial operations and customer data.

The reported data exposure includes highly sensitive personal and financial identifiers. Specifically, the compromised datasets are confirmed to contain Full Name, Social Security Number, Financial Account Number, Date of Birth, Routing Number, Credit Score Information, Transaction History, and Mailing Address. This collection of information is critical to an individual's financial identity.

Such a comprehensive compromise of financial data places affected individuals at significant risk. The combination of these exposed data types could enable unauthorized account access, identity theft, the opening of fraudulent lines of credit, and targeted financial scams that could persist over time. Vigilance over financial statements and credit reports is crucial.

As a federally regulated financial institution, Centennial Bank and Happy State Bank are obligated under laws like the Gramm-Leach-Bliley Act to implement robust security measures to protect customer information. The occurrence of this data breach suggests potential deficiencies in these safeguards, which could constitute a breach of duty to their account holders.
