Bank of America Data Breach Notice (Massachusetts Attorney General)

If you received a notice from Bank of America, here’s what the filing says was exposed, and what to do about it.

Bank of America notified Massachusetts residents of a data breach in a filing reported to the Massachusetts Office of Consumer Affairs on March 04, 2026, and the notice lists social security numbers and financial account numbers among the information exposed.

What to do now

Steps that match what this notice says was exposed

Every step below is free and you do it yourself, and none of it depends on Bank of America.

  1. Freeze your credit — this is the one that matters. A freeze is free, it takes minutes, and it has to be done separately at all three bureaus: Equifax, Experian and TransUnion. It stops a new account being opened in your name, which is what a Social Security number in the wrong hands is for. You can lift it temporarily whenever you need credit.
  2. Tell your bank before you do anything else. Account and routing details are the fastest-moving of the fields in this notice. Call the number on the back of your card rather than any number in an email, and ask them to watch the account and reissue the card.

One more, whatever was exposed: a breach notice is a favourite disguise for a phishing email. If a message about this arrives, do not use its links — go to the company’s site yourself, or call the number on your statement.
