What was the October 2024 Data Breach?
Western Alliance Bank recently disclosed a serious data breach affecting thousands of customers.

The hackers, identified as the CL0P ransomware group, claimed responsibility for the breach and threatened to publish stolen data on the dark web. They initially listed the bank as a victim on December 25, 2024, and revealed the full domain name (westernalliancebank.com) on January 15, 2025.
