WHAT HAPPENED?

Recently, Western Alliance reported to the Attorney General of Maine that it had experienced a data breach in which sensitive personal identifiable information in its care may have been accessed and acquired. According to the breach notice, on January 27, 2025, Western Alliance discovered that its third-party file transfer software contained a vulnerability that allowed an unauthorized actor to gain access to a portion of its systems.1 As a result, Western Alliance launched an investigation to determine the nature of the incident.

Through its investigation, Western Alliance confirmed that sensitive personal information in its systems may have been viewed and obtained between October 12 and October 24, 2024.1 As a result, Western Alliance began a review of the data to determine what information had been impacted as well as identify the specific individuals affected. While the information impacted varies depending on the individual, the type of information potentially exposed includes:

  • Name
  • Social Security number
  • Date of birth
  • Financial account number
  • Driver’s license number
  • Tax identification number
  • Passport

 

On March 14, 2025, Western Alliance provided initial notice to impacted individuals via email. Based on the breach notice sent to Maine residents, Western Alliance is providing affected individuals with a list of the specific types of sensitive information impacted and 12 months of complimentary credit monitoring services.
