Eisen, Inc. Data Breach Lawsuit Investigation
Received a June 2026 breach notice from Eisen?
Dapeer Law, P.A. is investigating a potential class action against Eisen, Inc., a New York-based financial services firm that manages unclaimed-property compliance, on behalf of individuals whose personal information may have been exposed when a file was disclosed in the December 2025 social-engineering incident.
Who may qualify
You may be eligible to participate in a class action if any of the following applies:
- You received a data breach notification letter from Eisen dated June 2026.
- Your letter offered enrollment in 24 months of free Experian credit monitoring and identity-restoration services.
- You had personal information held by Eisen in connection with its unclaimed-property compliance work.

What happened
According to a notice filed with the California Attorney General and consumer letters dated June 24, 2026, Eisen, Inc. reported that on December 12, 2025 it was targeted by a social-engineering scheme. An individual impersonating the California State Controller's Office requested a file containing unclaimed-property compliance records, and an Eisen employee, believing the request was legitimate, transferred the file. Eisen states that it identified the request as fraudulent shortly afterward and moved to contain the incident.
Eisen reports that it revoked the recipient's access, deleted the file from its sharing platform, and completed an internal investigation that it says found no further exposure. The company began notifying affected individuals on June 24, 2026, roughly six months after the December 2025 incident, and is offering 24 months of complimentary credit monitoring and identity-restoration services through Experian. According to the notice, the disclosed file may have included names, mailing addresses, email addresses, Social Security numbers, dates of birth, and information regarding unclaimed-property balances. The California filing does not state the total number of individuals affected.
Because the exposed information reportedly included Social Security numbers and dates of birth alongside contact details, recipients may face an elevated risk of identity theft and financial fraud. Dapeer Law is evaluating whether Eisen had reasonable safeguards and verification procedures in place to protect sensitive unclaimed-property records before the incident occurred.

Common questions
I received a data breach letter from Eisen. What should I do? +
Keep your breach notice letter, enroll in the free Experian credit monitoring and identity-restoration services using the code provided, and watch your bank, credit-card, and investment statements for unfamiliar activity. Because Social Security numbers were reportedly involved, consider placing a fraud alert or security freeze with the credit bureaus, and preserve all breach-related correspondence. You can also contact a data breach attorney to discuss your options.
Am I eligible to join a class action against Eisen? +
Individuals who received a breach notice from Eisen are the most likely to qualify. Eligibility can also depend on your state of residence, the categories of your data that were exposed, and whether you experienced any documented losses or fraud. A free consultation can help clarify where you stand.
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. No payout is guaranteed, and this investigation has not yet resulted in a settlement.
What personal information was exposed in the breach? +
According to the California notice, the disclosed file may have included names, mailing addresses, email addresses, Social Security numbers, dates of birth, and unclaimed-property balance information. Your individual letter should describe the specific data elements that applied to you, so check it carefully.
Did Eisen offer free credit monitoring? +
Yes. Eisen is offering 24 months of complimentary credit monitoring and identity-restoration services through Experian. The enrollment instructions and deadline are in your letter. Enrolling in this service does not waive your right to pursue a legal claim.

Is there a deadline to take legal action? +
