One of the five largest US banks has disclosed a massive data breach affecting 28 million customer accounts, including names, Social Security numbers, account numbers, and transaction histories.
What Was Exposed
- 28 million customer accounts
- Names, SSNs, dates of birth
- Account and routing numbers
- 12 months of transaction history
Response and Protection
The bank is offering 3 years of free credit monitoring and identity theft protection through Experian. Customers should immediately change online banking passwords, enable multi-factor authentication, and consider placing fraud alerts on credit reports.
The breach was discovered by a third-party security firm and appears to have exploited a vulnerability in the bank's legacy mainframe systems.
