On March 14, 2025, Western Alliance Bank ("WAB") disclosed a data breach affecting the personal information of its customers. According to the official disclosure filed with the California Attorney General's Office, the breach occurred between October 12, 2024, and October 24, 2024.

An investigation revealed that the breach originated from a vulnerability in a third-party vendor's secure file transfer software. This software was utilized by Western Alliance Bank and numerous other organizations. An unauthorized actor exploited this previously unknown vulnerability, gaining access to a limited portion of Western Alliance's systems and obtaining copies of files stored within those systems.

Western Alliance Bank became aware of the unauthorized access on January 27, 2025. Following an extensive review, the bank determined on February 21, 2025, that the compromised files contained sensitive personal information belonging to customers.

The exposed information includes customers' names, Social Security numbers, drivers' license numbers, and passport information.
