Eisner Advisory Group Data Breach Lawsuit

Eisner Advisory Group Data Breach Details

In September 2023, Eisner detected suspicious activity related to a limited set of data. Upon learning of this, the company immediately initiated a thorough investigation. The investigation revealed that unauthorized access occurred between September 4 and September 9, 2023. During this period, an unknown actor gained access to certain files, but the unauthorized access was confined solely to those specific files.

Eisner’s investigation continued throughout the following months, and by February 2025, the company confirmed that the impacted files contained personal information related to certain individuals, including some of those receiving this notice. The company has seen no evidence of any misuse of the information, but, as a precaution, Eisner is informing affected individuals.

As an added measure of caution, Eisner is offering complimentary credit monitoring services to all affected individuals. These services are intended to help individuals monitor their credit reports for any signs of fraudulent activity, providing peace of mind as they continue to safeguard their personal information.

What Information Was Exposed?

While the specific data elements vary by individual, the potentially exposed information could include:

Name

Address

Social Security number

Driver’s license or state-issued identification number

Passport number

Date of birth

Financial account information

Payment card information

Medical information or health insurance details

How to Know if You Were Affected

If you received a data breach notification from the Eisner Advisory Group, your personal information may have been compromised. While most victims are officially notified through a “Notice of Data Breach” in the mail, the consequences—such as fraudulent transactions and identity theft—can begin long before the notice arrives.

Steps to Take if You Were Affected by the Eisner Advisory Group Data Breach

Stay Alert for Phishing Scams
Scammers may exploit the data breach by posing as Eisner Advisory Group. Be cautious of unexpected emails, texts, or calls requesting personal information. When in doubt, verify communications directly with the company through official channels.

Monitor Your Credit and Financial Accounts
Regularly check your bank statements, credit card activity, and credit reports for unauthorized transactions. Set up account alerts to detect suspicious activity early. Take advantage of free credit reports and review them carefully for unfamiliar accounts or discrepancies.

Consider Freezing Your Credit
For added security, request a credit freeze from all three major credit bureaus. This prevents new accounts from being opened in your name while still allowing you to use existing credit. You can temporarily lift the freeze when necessary if applying for credit.
