Check My Rights →Citibank was the subject of a data breach notification filed with the MA Attorney General. The AG filing was recorded on April 15, 2026.
Citibank appears to be a major financial institution that provides banking, credit, and wealth management services to consumers and businesses. As part of its standard operations, the company routinely collects and stores sensitive customer information, including personally identifiable details and critical financial records. If you received a data breach notification letter, it is because your personal information was involved in a security incident officially reported to the Massachusetts Attorney General in 2026. This page provides an overview of the situation to help you understand what data may have been exposed and what steps you can take to protect your identity and financial accounts.
Based on the data types reported in this filing, affected individuals face the following specific risks:
Your SSN is the master key to your identity. Once exposed, criminals can open new lines of credit, take out loans, or file taxes in your name.
Combined with a name and other leaked data, date of birth helps criminals pass identity verification questions at banks and government agencies.
Home address exposure can enable mail theft, package fraud, and targeted phishing attacks that reference your known location.
Under the Massachusetts Data Security Law (201 CMR 17.00), you may have a legal claim against Citibank if any of the following apply:
Applicable law: This breach was reported under the Massachusetts Data Security Law (201 CMR 17.00), which establishes your right to seek damages from Citibank.
The hours spent responding to a data breach — canceling accounts, contacting credit bureaus, updating passwords, and investigating fraud — represent compensable economic harm in data breach litigation.
Once your SSN is exposed, protection becomes an ongoing expense. Plaintiffs in data breach settlements have recovered costs for credit freezes, identity protection subscriptions, and time spent dealing with fraudulent accounts — sometimes covering multiple years of exposure.
Fees charged to close and reopen accounts, issue replacement cards, or dispute fraudulent transactions are recoverable in data breach litigation. So are the costs of overdrafts, late payments, and credit damage caused by unauthorized activity.
Several state data breach laws provide for statutory minimum damages — fixed amounts recoverable per affected individual regardless of actual loss. These provisions exist specifically to make legal action viable for victims who have not yet experienced direct harm.
Note: an attorney general breach filing does not by itself establish a settlement fund, a payment amount, or a claim deadline. If an official settlement notice is later issued, rely on that notice for payment details and deadlines.
No. Under Massachusetts Data Security Law (201 CMR 17.00) and federal law, the unauthorized exposure of your personal data — regardless of whether it has been actively misused — can be sufficient grounds for a claim. The breach itself is the injury.
Nothing. The Law Office of David S. Harris handles data breach cases on contingency — you pay zero upfront and owe nothing unless compensation is recovered.
Immediately place a free credit freeze at all three bureaus (Equifax, Experian, TransUnion). A freeze blocks new accounts from being opened in your name. Then file a complaint with the FTC at IdentityTheft.gov and contact our office — SSN exposure is one of the most serious breach types.
Banks may reverse fraudulent charges, but they are not obligated to compensate you for time lost, stress, or indirect damages. A class action claim against the breached company can recover those additional categories of harm.
State statutes of limitations for data breach claims typically run 2–4 years from the date of the breach or its discovery. Because this breach was recently disclosed, the window is open — but acting early preserves your options and strengthens the case.
Accepting free credit monitoring from Citibank does not waive your right to pursue legal action unless you signed a specific release waiving claims. In most cases, victims who accepted monitoring can still file.
Not necessarily. Many data breach victims are never notified directly. If your personal information was held by Citibank during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
