Bank Issues Warning To 3,996 Customers After Detecting ‘Unauthorized Access’ To Highly Sensitive Information

A US bank is warning nearly 4,000 customers that their names, Social Security numbers and financial account information could be at risk after a data breach.

Last May, the Florida-based Flagship Bank “became aware of suspicious activity within their environment” and launched an investigation, per a new filing with the Office of the Maine Attorney General.

“The investigation determined unauthorized access within Flagship Bank’s environment occurred on April 15, 2025, due to a social engineering scheme.

Although we have no evidence of any identity theft or fraud occurring in connection with this incident, Flagship Bank conducted a review of relevant systems and is notifying those whose information was present within the systems.”

The community bank operates six branches throughout Florida as well as a Community Association Banking (CAB) Division, which offers lending, deposits and cash management services to condo and homeowner’s associations.

In a letter to customers, the financial institution said it notified federal law enforcement about the data breach and has been working to provide its employees with additional training to prevent future incidents.

Flagship Bank says it is also offering 12 months of credit monitoring services through the credit reporting agency TransUnion, and says it will provide “proactive fraud assistance” to help with any questions from customers.
