What Happened

According to a notification filed with the Texas Attorney General, Happy State Bank and its parent, Centennial Bank, reported a data security incident affecting customer information. Public accounts describe the incident as arising from a third-party vendor error: an associate at Fidelity Information Services (FIS), which assists the bank with certain banking operations, is said to have prepared a secure email containing a customer file and inadvertently sent it to an unintended recipient — reportedly an employee at another financial institution.

Public accounts indicate the misdirected file was sent on or about August 7, 2026, and that the unintended recipient opened it on or about August 10, 2026, before notifying FIS. FIS and the bank report taking steps to contain the incident, including recalling the email, terminating access to the file, and confirming the file was destroyed.

Important details — including the incident's true scope, the specific data involved for each individual, and the total number of people affected nationwide — have not been fully confirmed publicly.

What Personal Information May Be at Risk

Based on the notification filed with the Texas Attorney General, the information potentially involved may include:

• Names
• Social Security numbers
• Dates of birth
• Addresses
• Driver's license numbers
• Government-issued identification numbers
• Financial information, such as account or credit and debit card numbers
• Health insurance information
• Other sensitive personal information

Anyone who has received a data breach notification connected to this incident may face an increased risk of identity theft and fraud and is encouraged to come forward.
