Eisner Advisory Group LLC has sent letters to individuals whose personal information sat in a set of files that an unknown actor accessed and took between September 4 and September 9, 2023. The company says it first noticed unusual activity around that time, but it took until February 2025 to finish reviewing exactly which files were affected and whose information appeared in them. Eisner describes this as a hacking or system intrusion carried out by an outside party, and states that access by that actor was limited to the files in question.
The letter is addressed to a specific person and does not give a nationwide total of how many people were notified. It does note that roughly 53 Rhode Island residents are among those affected, which suggests the notification went out to people across multiple states. If you received this letter, Eisner has confirmed that information tied to you specifically was found in the compromised files.
What data did Eisner actually confirm was taken?
- Your full name
- Additional personal information — the version of this letter provided to BreachLetter uses a placeholder for the specific data category and doesn’t spell out exactly what else was included beyond your name
Because Eisner is offering credit monitoring as part of its response, it’s worth treating this as a signal that more sensitive identifiers, such as a Social Security number or financial account details, may have been among the information involved, even though the letter itself doesn’t list them by name in the copy we reviewed.
As part of its response, Eisner is offering complimentary credit monitoring services through IDX. You’ll need to sign yourself up — the company cannot activate the service on your behalf. To enroll, go to https://response.idx.us/Eisner and enter the enrollment code printed at the top of your personal letter, or call 1-877-782-4279 (Monday through Friday, 9 am to 9 pm Eastern). Enrollment must be completed by July 8, 2025.
Practical steps to take before the enrollment deadline
- Sign up for the free IDX credit monitoring using your enrollment code before July 8, 2025, since the offer won’t be extended automatically.
- Pull your free credit reports from Equifax, Experian, and TransUnion at annualcreditreport.com and look for accounts or inquiries you don’t recognize.
- Consider placing a fraud alert or a credit freeze with the three major bureaus — a freeze is free under federal law and stops new credit from being opened in your name without your direct authorization.
- Since Eisner’s letter doesn’t fully specify every data element involved, consider signing up for a service like Aura or LifeLock, which can alert you if your information appears elsewhere, such as on data-broker sites or in stolen-data listings.
- Watch your bank and credit card statements closely over the coming months, and report anything suspicious to your financial institution right away.
- If you ever suspect your identity has been misused, file a report with the FTC at identitytheft.gov and with your local police department.
