Centennial Bank (Happy State Bank) Data Breach Exposes Customer Financial Information

Centennial Bank, operating in Texas and encompassing its division Happy State Bank, recently disclosed a data security incident. The breach, which occurred on August 7, 2026, was formally reported to the Office of the Texas Attorney General on September 17, 2026, raising concerns for the financial institution's customers.

The breach has been confirmed to involve a range of highly sensitive customer data. Exposed information includes Full Name, Social Security Number, Financial Account Number, Date of Birth, Routing Number, Credit Score Information, Transaction History, and Mailing Address. This combination of data is particularly valuable to malicious actors.

With such detailed information in hand, individuals whose data was compromised face a heightened risk of identity theft, account takeover, and various forms of financial fraud. This could manifest as unauthorized access to existing accounts, opening of new lines of credit in your name, or even fraudulent tax filings. The potential for long-term financial harm is significant.

As a financial institution, Centennial Bank and Happy State Bank are obligated under strict regulations like the Gramm-Leach-Bliley Act to protect customer data. A breach of this nature suggests potential failures in safeguarding this sensitive information, raising questions about the adequacy of their security measures.
