Was this a ransomware attack?

The filing does not say ransomware was involved. We do not label an incident ransomware unless the company’s report says so. Whatever the cause, the steps to protect yourself and the legal question are the same.

What we know

Heritage Bank has reported a security incident to the California Attorney General on April 23, 2026, after an unauthorized party gained access to the financial institution's network. Because banks maintain deep financial and identity-related records for their customers, the breach compromised sensitive personal information belonging to account holders. While the exact total of affected individuals has not been publicly disclosed, the exposed files originate directly from the bank's internal systems. When personal information of this nature is compromised, it exposes individuals to distinct real-world risks such as targeted phishing attacks, unauthorized credit applications, and fraudulent financial accounts opened in their name. Because this type of data is permanent and cannot simply be changed like a password, victims face a prolonged threat of identity theft and financial monitoring. Securing your accounts and tracking your credit reports closely is critical to mitigating these ongoing security vulnerabilities. If you received an official notification letter in the mail from Heritage Bank regarding this incident, you may be eligible to join a class action lawsuit to pursue accountability and compensation. You can request a completely free, no-obligation case review right now with zero upfront costs or out-of-pocket expenses.

After the Heritage Bank incident: what to do and your options

What should I do after getting the Heritage Bank data breach notice?
Keep the letter and the envelope, and note the date it arrived. Freeze your credit with Equifax, Experian and TransUnion, change any passwords the notice mentions, and sign up for any free credit monitoring the letter offers. Then check whether you may have a claim.
Did Heritage Bank offer free credit monitoring?
Look for an enrollment code in your Heritage Bank notice. Companies that offer free credit monitoring after a breach usually include it there, with a deadline to activate. Using the free service won't stop you from joining a lawsuit or settlement later.
Where can I see the official Heritage Bank breach notice?
Heritage Bank's report is published by the CA Attorney General: https://oag.ca.gov/privacy/databreach/list#heritage-bank-2026-04-23 Compare it with the letter you received to confirm the dates and details match.
Can I sue Heritage Bank over the data breach?
It depends on what was exposed, the law in CA and your own state, and whether you've been harmed. Most people take part through a class action rather than suing alone. Keep your notification letter — it's the proof that connects you to the breach.
Do I need a Heritage Bank data breach lawyer or attorney?
Whether the company's systems were encrypted by ransomware or data was simply taken, the legal question is the same: did it protect your information the way the law requires? An attorney can review your notice for free, and these cases are usually handled on contingency.
Is there a Heritage Bank data breach class action lawsuit?
Law firms often open an investigation after a breach notice like this one, and a class action lawsuit may follow. This page doesn't confirm that a lawsuit has been filed against Heritage Bank. You usually don't have to join a class action to be included — if a settlement is reached, class members are notified and can file a claim.
Is the Heritage Bank data breach letter legit or a scam?
A notice from Heritage Bank in the mail matches the breach Heritage Bank reported to the CA Attorney General on April 23, 2026. Check that the company name and dates in your letter match that filing. A real notice of data security incident won't ask for your password, Social Security number or a payment — if it does, contact Heritage Bank through a phone number or website you find yourself.
How much could a Heritage Bank data breach settlement or claim be worth?
There is no set amount, and no Heritage Bank settlement is confirmed here. In past data breach settlements, payments depended on what data was exposed and on documented losses — fraud, out-of-pocket costs and time spent dealing with the breach. Keep receipts and records; they're what damages claims are built on.
