What happened
According to a notice filed with the Massachusetts Attorney General, Aesto, LLC, a technology vendor that provides healthcare data migration and archiving services to Diana Health, experienced a security incident affecting a portion of its Amazon Web Services environment. An unauthorized actor began copying data from that environment on December 2, 2025, and the unauthorized activity continued until December 18, 2025. The data copied during that window included protected health information relating to Diana Health patients. The notice states that clinical records and notes from office visits were not involved.
A forensic investigation supported by external cybersecurity professionals confirmed the scope of the copied data on May 26, 2026. Written notices were mailed on August 28, 2026, roughly nine months after the unauthorized access began and about three months after the review was completed. The Massachusetts filing reports that 23 Massachusetts residents were notified, and a separate Rhode Island filing references 12 residents in that state. A total nationwide figure has not been publicly disclosed. The filing identifies Social Security numbers among the data elements involved, and Diana Health is offering affected individuals complimentary single-bureau credit monitoring, credit report, and credit score services through Cyberscout.
Social Security numbers are among the most sensitive identifiers a person holds, because they cannot be changed and can be used to open accounts, file fraudulent tax returns, or claim benefits long after a breach. Because the information was held by a third-party vendor rather than by the practice itself, Dapeer Law is also evaluating how Diana Health vetted and oversaw its technology partners, and whether the nine-month gap between the incident and consumer notification complied with state breach notification laws.

Common questions
I received a data breach letter from Diana Health. What should I do? +
Keep your notice letter, enroll in the free Cyberscout credit monitoring using the code in your letter, and consider placing a security freeze with all three major credit bureaus. Because Social Security numbers are reported to be involved, also watch for unfamiliar accounts, unexpected mail from lenders, and any notice that a tax return was already filed in your name. A data breach attorney can explain your rights at no cost.
Am I eligible to join a class action against Diana Health? +
Individuals who received a notice dated August 28, 2026 are the most likely to qualify. Whether you can participate can depend on your state of residence, the categories of your data that were exposed, and any documented losses or time you spent responding to the incident.
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 Massachusetts Attorney General filing identifies Social Security numbers among the data elements copied during the incident. The notice states that clinical records and notes from office visits were not involved. Your individual letter should list the specific data elements that applied to you, so check it for the details of your own exposure.
Did Diana Health offer free credit monitoring? +
Yes. Affected individuals are being offered complimentary single-bureau credit monitoring, credit report, and credit score services through Cyberscout, with enrollment required within 90 days of the letter date. The notice does not state how long the monitoring lasts. Enrolling does not waive your right to pursue a claim.
How many people were affected by the Diana Health breach? +
The Massachusetts Attorney General filing lists 23 notified Massachusetts residents, and a Rhode Island filing references 12 residents in that state. A total nationwide figure has not been publicly disclosed. This page will be updated as more becomes known.
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.
