What happened
On or about December 18, 2025, Aesto, LLC, a vendor that provides healthcare data migration and archiving services for Monroe County Health Center, experienced a network security incident affecting a limited portion of its Amazon Web Services environment. That environment stored protected health information belonging to Monroe County Health Center patients. Aesto reports that it began an investigation on learning of the issue, engaged outside cybersecurity professionals, and put additional security safeguards in place.
After a forensic investigation and a manual document review, Aesto confirmed on May 26, 2026 that between on or about December 2 and December 18, 2025, an unauthorized actor may have accessed or acquired certain files. Written notice was mailed on August 7, 2026 and filed with the Massachusetts Attorney General. According to that notice, the information involved may have included full name, personal demographic details, and Social Security number. Aesto states there is no evidence of misuse. Monroe County Health Center is offering impacted individuals a complimentary 24-month Experian IdentityWorks credit monitoring and identity theft protection membership, with enrollment open through November 30, 2026.
Healthcare providers and the vendors they hire are required under HIPAA and various state laws to safeguard patient information, and a provider's obligations generally do not disappear when records are handed to a third-party contractor. The gap of roughly eight months between the December 2025 discovery of the incident and the August 2026 mailing of notice letters is one of the factors our firm is reviewing, because notification delays can bear on claims under several state breach notification statutes. Social Security numbers do not change, so exposure of that data element carries a long-term identity theft risk.
What to do if you received a letter
Keep your notice letter
Do not discard it. Your letter contains the enrollment code for credit monitoring and is important evidence if you decide to participate in a lawsuit.
Enroll in the free 24-month credit monitoring
Enroll in the Experian IdentityWorks membership offered in your letter. To activate, follow the enrollment instructions and activation code printed in your notification letter, and complete enrollment by November 30, 2026. 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 Social Security numbers may have been involved, also watch for unfamiliar Explanation of Benefits letters, medical bills for care you did not receive, and tax filings or new credit accounts opened in your name.
