10,953 Customers at Two US Banks Receive Data Breach Alerts As Lenders Warn Extremely Sensitive Information at Risk

Two US banks are issuing alerts to customers informing them that their personally identifying data has potentially been compromised.

According to new filings with the Office of the Maine Attorney General, TD Bank and Summit National Bank say they’ve suffered data breaches that occurred between the third quarter of 2023 and the second quarter of this year.

Wyoming-based Summit National Bank says it initially discovered suspicious activity in May and has now determined a data breach occurred between the 13th and 16th of the same month.

The bank says 10,912 customers are affected by the breach.

In a notice to customers, the bank says the information that “could have been subject to unauthorized access” includes names, Social Security numbers, and financial account information.

Meanwhile, TD Bank says in a separate filing with the Office of the Maine Attorney General that an insider is behind a data breach that affected 41 customers. In its notice to customers, the bank says the breach was discovered on July 16th, although it had happened months earlier.

“We recently discovered that between September 2023 and March of 2024 one of our employees improperly accessed some of your personal information without a legitimate business purpose. We realize this is not news you want to hear, and we’re truly sorry.”

On the extent of the data breach affecting it, TD Bank says the leaked personal information may included names, addresses, social security numbers, dates of birth, debit card numbers, expiration dates, and security codes.
