Western Alliance Bank Data Breach Investigation

Migliaccio & Rathod LLP is involved in the Western Alliance Bank Data Breach Investigation for a data breach that affected an 21,899 individuals and their personal information.

In October of 2024 a malicious party began exploiting  vulnerability in third-party software used by  Western Alliance Bank. On January 27, 2025, Western Alliance Bank learned that this suspicious party had accessed customer data. Western Alliance Bank subsequently conducted an investigation, which uncovered that a cybercriminal had stolen the files containing the personally identifiable information of its consumers stored therein, including the following:

  • full names
  • Social Security numbers
  • driver’s license numbers
  • financial account information
  • tax identification numbers
  • passport information

The Western Alliance Bank Data Breach

Western Alliance Bank recently provided notice of the data breach. All of the information stolen is likely valuable and dangerous to affected victims. As is likely to be the case with the Western Alliance Bank data breach, in previous cyberattacks, victims of data theft have noticed identity theft attempts ranging from fraudulent charges on bank accounts or credit cards, to unauthorized credit card applications, to medical services or government services ordered in their name, to their information being posted on the dark web, to a massive uptick in the number of spam text messages, calls and emails received.
