Eastern Bank was the subject of a data breach notification filed with the MA Attorney General. The AG filing was recorded on January 30, 2025.
From the AG filing description
Eastern Bank is a prominent financial institution and full-service commercial bank operating extensively across Massachusetts and the broader New England region. As a trusted provider of consumer banking, commercial lending, wealth management, and mortgage services, the institution routinely collects, processes, and stores vast quantities of highly sensitive personal and financial data. Because customers rely on Eastern Bank to manage their daily transactions, savings, investments, and loan applications, the institution holds immense volumes of confidential consumer and business records that require rigorous cybersecurity safeguards. In 2025, Eastern Bank reported a significant data security incident to the Office of the Massachusetts Attorney General, raising serious concerns among account holders and legal analysts alike. While the precise vectors of the intrusion continue to be evaluated through ongoing forensic investigations, incidents affecting prominent financial institutions typically involve sophisticated cyberattacks, unauthorized network intrusion, or the exploitation of vulnerable third-party vendor platforms used for banking operations and data storage. Threat actors actively target financial entities to intercept sensitive data streams, exfiltrate proprietary databases, or disrupt critical financial infrastructure. The data compromised in financial sector data breaches frequently includes core identifying and transactional elements such as full names, Social Security numbers, dates of birth, financial account numbers, bank routing numbers, and credit histories. The exposure of this combination of data creates severe, immediate risks for affected consumers. When cybercriminals obtain Social Security numbers alongside banking credentials and account details, victims face an elevated threat of financial account takeover, unauthorized wire transfers, fraudulent loan applications, and persistent identity theft that can take years to fully resolve. As a financial institution operating in the United States, Eastern Bank is subject to stringent federal and state regulatory frameworks, including the Gramm-Leach-Bliley Act (GLBA) and Massachusetts data privacy and security statutes. These legal mandates require financial entities to implement robust administrative, technical, and physical safeguards to protect non-public personal information against unauthorized access and cyber threats. A data breach of this magnitude strongly suggests potential failures in maintaining adequate network security controls, continuous monitoring, and vendor risk management protocols, raising questions regarding the institution's compliance with established industry standards. Receiving an official data breach notification letter from Eastern Bank serves as formal confirmation that your private financial and personal information was compromised due to corporate security shortcomings. Legally, this notification establishes your standing to participate in a class action lawsuit aimed at holding the institution accountable and securing compensation for the risks and disruptions you now face. Under established legal principles, affected individuals do not need to prove that out-of-pocket financial fraud has already occurred to seek legal redress. Our firm evaluates and litigates these data privacy cases on a contingency fee basis, meaning you pay no upfront costs or out-of-pocket attorney fees unless we successfully recover compensation on your behalf.
Based on the data types reported in this filing:
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.
You may have been affected by the Eastern Bank data breach if:
Common categories of compensation in data breach class actions
Courts recognize that the time spent monitoring accounts, placing credit freezes, and dealing with the aftermath of a breach has real economic value. This category of damages is recoverable even without direct financial loss.
Professional credit monitoring services cost $10–$40 per month. Identity theft restoration services, if needed, can cost hundreds of hours and thousands of dollars. Courts have awarded these costs as direct damages in SSN breach cases.
Direct financial losses resulting from the breach — unauthorized charges, fraudulent transfers, or fees incurred through fraud — are recoverable as compensatory damages. Banks may reverse some charges; a class action recovers the remainder and associated costs.
Data breach victims regularly report anxiety, loss of sleep, and ongoing fear of identity theft. These non-economic harms are cognizable injuries in data breach litigation, particularly in cases involving SSN or medical record exposure.
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.
Applicable State Law
This breach was reported under the Massachusetts Data Security Law (201 CMR 17.00), which mandates notification and establishes your right to seek damages.
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.
Statutes of limitations for data breach claims vary by state but typically run 2–4 years. Depending on when you learned of the breach, you may still have time. Contact our office for a free eligibility review — there is no cost to find out.
Accepting free credit monitoring from Eastern Bank 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 Eastern Bank during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
