What happened
On or about March 2, 2026, Heritage Bank identified unauthorized activity within its network. According to the Bank's public Notice of Security Incident, Heritage Bank immediately isolated and secured the affected environment and engaged third-party specialists to investigate. The investigation revealed that certain files had been copied from an internal file share server on March 1, 2026. Heritage Bank states that customer accounts, customer systems, and operations were not impacted by the incident itself, only the contents of the file share server. Sample notification letters filed with state regulators reference impacted residents in multiple states, including California, Maryland, New York, North Carolina, Rhode Island, and the District of Columbia.
The information present in the reviewed files varied by individual and may include the affected person's name paired with one or more of the following: account number, Social Security number or Individual Taxpayer Identification Number (ITIN), date of birth, and address. Because the file share server was used by Heritage Bank employees, both customers and employees may be among the potentially impacted individuals. Heritage Bank is providing impacted individuals with complimentary single-bureau credit monitoring, a credit report, a credit score, and proactive fraud assistance through Cyberscout, a TransUnion company, with a 90-day enrollment window from the date of the notification letter. Heritage Bank also published a Notice of Security Incident on its website (last updated March 20, 2026) and made a dedicated assistance line available at 1-833-877-5751, Monday through Friday from 5 a.m. to 5 p.m. Pacific Time.
The combination of names paired with Social Security numbers, ITINs, dates of birth, and bank account numbers is high-value identity theft fuel. Affected individuals face elevated risk of synthetic identity fraud, tax refund fraud, account takeover, and unauthorized credit applications opened in their name. Dapeer Law is evaluating whether Heritage Bank used reasonable security safeguards consistent with banking industry standards, whether internal file share access was appropriately controlled, and whether affected customers and employees can pursue monetary relief through individual claims or a class action.

Common questions
I received a data breach letter from Heritage Bank. What should I do? +
Keep the notice, activate the complimentary single-bureau credit monitoring through Cyberscout (a TransUnion company) using the enrollment code in your letter within the 90-day window, place a fraud alert or freeze with Equifax, Experian, and TransUnion, and review your bank account statements closely for unauthorized activity. Because the breach involved Social Security numbers, ITINs, dates of birth, and account numbers, also watch for unfamiliar tax filings, new accounts opened in your name, or unauthorized credit applications. A free consultation with a data breach attorney can help you understand your legal options.
Am I eligible to join a class action against Heritage Bank? +
Individuals who received a Heritage Bank notification regarding the March 2026 security incident may be eligible. Eligibility can be affected by your state of residence, whether you were a customer or employee, the categories of data exposed in your specific letter, and any documented losses you have already incurred. Dapeer Law will evaluate your notice at no cost and confirm whether you appear to qualify.
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. Breaches involving Social Security numbers and bank account data, like the Heritage Bank incident, often command higher per-class-member recoveries.
