What happened
Marana Health Center, a community health center in Marana, Arizona, is among the healthcare providers notifying patients about a security incident at Aesto, LLC, a Birmingham, Alabama based company that provides healthcare data migration and archiving services. According to the notice filed with the California Attorney General on October 1, 2026, Aesto experienced a network security incident on or about December 18, 2025, and an unauthorized actor may have accessed and/or acquired information stored in a limited portion of Aesto's Amazon Web Services environment between on or about December 2 and December 18, 2025. Aesto states the incident did not affect its clients' own systems.
Aesto engaged external cybersecurity professionals, conducted a forensic investigation, and completed a manual review of the affected documents on May 26, 2026. Aesto began notifying its healthcare provider clients on June 26, 2026, and the Marana Health Center notice was filed with the California Attorney General on October 1, 2026, roughly nine and a half months after the December 2025 access window. The sample letter in the public filing does not itemize the data involved, but Aesto has reported that the affected information may include full names, dates of birth, medical information, health insurance information, and Social Security numbers, and for some individuals driver's license numbers, financial account numbers, individual taxpayer identification numbers, or other government ID numbers. The categories vary by person. A related filing reportedly lists 47 affected Massachusetts residents, and the total number of Marana Health Center patients affected has not been publicly disclosed. Aesto has reported no evidence that the information has been misused.
The Aesto incident has been reported to federal regulators as affecting more than 9.5 million people across dozens of healthcare provider clients, and multiple proposed class actions against Aesto are pending in federal court in Alabama. Medical information paired with Social Security numbers can support both financial fraud and medical identity theft, where someone obtains care or prescriptions under a patient's identity. Healthcare providers and the vendors they rely on have duties under HIPAA and state privacy laws to safeguard this information.
What to do if you received a letter
Keep your notice letter
Do not discard it. Your letter contains the enrollment instructions and activation code for the monitoring services and is important evidence if you decide to participate in a lawsuit.
Enroll in the free monitoring services
Enroll in the complimentary monitoring offered in your letter, using the activation instructions and code printed in the notice. Enrollment is open for 90 days from the date of the letter. Accepting this benefit does not waive your right to pursue legal action.
Place a fraud alert or credit freeze
Contact Equifax, Experian, and TransUnion to place a fraud alert or freeze on your file. Request a free weekly credit report from AnnualCreditReport.com, and use the FTC's IdentityTheft.gov recovery guide. Because this is a healthcare breach, also review Explanation of Benefits statements and provider billing summaries for care you did not receive, and request a copy of your medical file if anything looks unfamiliar.

Common questions
I received a data breach letter from Marana Health Center. What should I do? +
Keep the letter, enroll in the complimentary monitoring using the instructions and code in your notice within the 90-day enrollment window, order and review your free credit reports at AnnualCreditReport.com, and consider placing a fraud alert or a security freeze on your credit file. If your letter lists your Social Security number, requesting an IRS Identity Protection PIN is also worth considering. Review your Explanation of Benefits statements and medical bills for treatment you did not receive. Accepting monitoring does not waive your right to sue.
Am I eligible to join a class action against Marana Health Center? +
If you received a breach notice about Marana Health Center patient information involved in the Aesto incident, you may be eligible for a free case evaluation. Eligibility depends on your state of residence, the categories of your information that were involved, and any losses or out-of-pocket costs you have incurred. Dapeer Law will review your notice at no cost.
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? +
The sample letter filed with the California Attorney General does not itemize the data involved. Aesto has reported that affected information may include names, dates of birth, medical and health insurance information, and Social Security numbers, and for some individuals driver's license numbers, financial account numbers, taxpayer identification numbers, or other government ID numbers. Your individual letter should state the categories that applied to you. If you no longer have it, Dapeer Law can help you obtain a copy.
Did Marana Health Center offer free credit monitoring? +
Yes. The notice offers complimentary monitoring services, with enrollment instructions and an activation code printed in each letter and enrollment open for 90 days from the date of the letter. The sample letter in the public filing describes an Equifax monitoring package, and the duration is not stated in the public filing. Check your own letter for the exact service and term. Enrolling is separate from, and does not waive, your right to pursue a claim.
How many people were affected by the Marana Health Center breach? +
The total number of Marana Health Center patients affected has not been publicly disclosed. A related filing reportedly lists 47 affected Massachusetts residents, and the overall Aesto incident has been reported to federal regulators as affecting more than 9.5 million people across its healthcare clients. This page will be updated as additional information becomes available.
Is there a deadline to take legal action? +
Yes. Statutes of limitations for data breach claims vary by state and legal theory, typically ranging from one to six years. Waiting can permanently bar your claim. Contact us as soon as possible for a free evaluation.
