What happened
According to a notice filed with the Massachusetts Office of the Attorney General, an email-phishing scheme on August 26, 2026 led an employee of Millbury National Bank to disclose customer information to an unauthorized party. The bank reports that the incident began and ended the same day it was discovered, and that it notified the state and the affected consumers on August 26, 2026.
The filing indicates that 29 Massachusetts residents had information involved, including names, mortgage lien information, account numbers, loan balances, payment status, phone numbers, and other financial account details. Millbury National Bank did not offer complimentary credit monitoring. Instead, it states that it has placed an alert on each affected account, is taking steps to prevent unauthorized transactions, and advises customers to place a free security freeze with the three national credit bureaus.
The notice also warns customers that the bank will never request private information by phone or email, and asks anyone who receives such a request to verify it by calling the publicly listed number, 508-865-9521. Because the disclosed data pairs account numbers with loan balances and payment status, the information is well suited to convincing follow-on impersonation attempts targeting mortgage borrowers. Whether the bank maintained adequate phishing controls and employee training, and whether affected customers face continuing fraud exposure, are among the issues under review.
What to do if you received a letter
Keep your notice letter
Do not discard it. Your letter documents that your information was involved and is important evidence if you decide to participate in a lawsuit.
Place a free security freeze on your credit reports
Because Millbury National Bank did not offer credit monitoring, consider placing a free security freeze with Equifax (800-349-9960), Experian (888-397-3742), and TransUnion (888-909-8872). Massachusetts residents may place or lift a security freeze free of charge. Taking this step does not waive your right to pursue legal action.
Place a fraud alert or credit freeze
Contact Equifax, Experian, and TransUnion to place a fraud alert or freeze on your file. Request a free weekly credit report from AnnualCreditReport.com, and use the FTC's IdentityTheft.gov recovery guide. Treat any unexpected call, text, or email about your mortgage as suspect, and verify it by calling Millbury National Bank at its publicly listed number, 508-865-9521, rather than any number provided in the message.

Common questions
I received a data breach letter from Millbury National Bank. What should I do? +
Read the notice carefully and keep it, follow the bank's verification instructions and never give account information to an unverified caller, consider placing a free security freeze with Equifax, Experian, and TransUnion, monitor your mortgage and deposit account statements closely for the next 12 to 24 months, report anything suspicious to Millbury National Bank at 508-865-9521, and contact a data breach attorney for a free consultation.
Am I eligible to join a class action against Millbury National Bank? +
If you received a breach notice from Millbury National Bank, you are likely eligible for a free case evaluation. Eligibility depends on whether your information was among the 29 affected records, your state of residence, and whether you have suffered financial losses or spent time responding to the incident. A legal review will clarify your rights.
How much money could I receive from a class action lawsuit? +
Data breach class action recoveries vary significantly. Settlements typically range from a few hundred dollars for basic out-of-pocket losses to several thousand dollars for documented identity theft, with class size, damages, and negotiation all affecting the final amount. No payout is guaranteed, and this investigation has not yet resulted in a settlement.
What personal information was exposed in the breach? +
According to the notice filed with the Massachusetts Attorney General, the information disclosed included names, mortgage lien information, account numbers, loan balances, payment status, phone numbers, and other financial account details. Your individual notice letter should confirm what applies to your accounts.
Did Millbury National Bank offer free credit monitoring? +
No. The notice does not offer any complimentary credit-monitoring service. Millbury National Bank instead says it has placed an alert on each affected account and advises customers to place a free security freeze with the three national credit bureaus.
