What is this about?

If you recently received a letter or an email from Western Alliance Bank ("Western Alliance") informing you that your sensitive personal information was compromised in a data breach, you may be entitled to compensation. Western Alliance recently disclosed that it was the victim of a data breach that exposed individuals’ sensitive personal information.

What Happened?

On January 27, 2025, Western Alliance became aware of a security incident related to a vulnerability in a third-party vendor’s secure file transfer software. The vulnerable application exploited in the attack, which the firm did not name, is a Cleo file transfer tool. A third-party vendor’s secure file transfer software used by Western Alliance and numerous other organizations had an unknown vulnerability. In October 2024, an unauthorized actor began exploiting this unknown vulnerability in the third-party software, allowing them to gain access to a limited portion of Western Alliance’s systems and obtain copies of files from those systems. Western Alliance learned that an unauthorized actor had potentially accessed some of Western Alliance’s data on January 27, 2025. The investigation determined that the unauthorized actor acquired certain files from the systems from October 12, 2024, to October 24, 2024.

Western Alliance conducted a comprehensive review of the impacted data to determine what information was compromised and identified affected individuals. On March 14, 2025, Western Alliance filed a notice with the Maine Attorney General and began notifying impacted individuals.
