Western Alliance Bank Data Breach Class Action

At Console & Associates, our data breach lawyers are closely examining the recent Western Alliance Bank data breach. This data breach was disclosed following a cyber security incident at Western Alliance Bank, which may have affected as many as 21,889 individuals, potentially exposing sensitive personal identifiable information.

What Happened?

A recent report from the Maine Attorney General's Office states that the Western Alliance Bank data breach occurred due to a cyber security incident involving a vulnerability in a third-party software product used by the bank.

Between October 12, 2024, and October 24, 2024, an unauthorized party exploited this previously unknown software vulnerability to gain access to portions of Western Alliance Bank's IT network. During this 12-day window, the unauthorized individual accessed specific files containing confidential customer information stored on the bank's systems.

Upon discovering the security breach, Western Alliance Bank initiated a comprehensive investigation to identify the extent of the intrusion and determine which customers were affected. The bank completed its review of the compromised files on February 21, 2025, confirming that the exposed information included customers' names and Social Security numbers.

Data breach letters were sent out by Western Alliance Bank on March 14, 2025, informing affected individuals about the nature of the incident and compromised data. These notifications provide recipients with details regarding what specific personal information of theirs was exposed during the breach.
