8,358 Bank Customers Exposed As Billion-Dollar Lender Reveals Data Breach, Warns Social Security Numbers and Account Details at Risk

A billion-dollar US bank is warning thousands of customers of a major data breach.

According to a filing with the Office of the Maine Attorney General, 8,358 customers at Citizens Bank – which is the 16th-largest bank in the US by total assets – are impacted.

The breach is attributed to “insider wrongdoing” believed to have happened on October 23rd of 2023.

Citizens Bank says the breach involves highly sensitive customer information.

“Information that may have been involved includes your Citizens account number(s), social security number, date of birth, or identification details.”

The bank is offering affected customers a two-year membership to an identity theft credit monitoring service.

The incident comes two months after the bank suffered a separate security breach.

In October, Citizens Bank detailed a data breach that exposed the personal information of approximately 100 customers to an unauthorized party.

The Providence, Rhode Island-headquartered bank currently has about $220 billion in total assets, according to the Federal Reserve.
