Dr. Larisa Khmil has sent a data breach notice to people whose personal information may have been exposed when an unauthorized person reached employee email accounts at her former practice. The notice says the practice no longer exists, and that the incident happened on or about July 15, 2025.
The letter was posted by the Massachusetts Attorney General’s office. A person who keeps records for patients or clients is expected to keep them safe, and that duty continues even after a practice has closed.
Dr. Larisa Khmil’s Data Breach Investigation
The notice is written in the first person by Dr. Larisa Khmil, and it explains that the incident took place at her prior practice, which is no longer in existence. She says she is writing so that people understand what happened and to let them know she continues to take measures to protect their information. The notice does not name the former practice, so readers who received it may be recognizing the sender rather than the practice name.
According to the notice, on or about July 15, 2025, Dr. Khmil learned that an unauthorized individual had accessed a limited number of employee email accounts. She says she began an investigation right away with outside cybersecurity professionals who handle this type of incident. After what the notice describes as an extensive forensic investigation and comprehensive data review, she discovered on October 6, 2026 that certain files containing personal information may have been subject to unauthorized access or acquisition on July 15, 2025.
Those dates tell an important story. The access happened on July 15, 2025, but the review that identified which files held personal information was not finished until October 6, 2026. That is a gap of more than a year between the incident and the point at which the sender knew that personal information may have been involved. Reviewing the contents of compromised email accounts is slow work, since messages and attachments can hold years of correspondence, and it can take months to work out who is named in each file. That does not remove the questions a long delay raises for the people who were not told for so long.
The Massachusetts filing list shows that two Massachusetts residents were affected. That figure is specific to Massachusetts. The notice is a form letter that appears to have been sent in several states, since it includes sections of state-specific guidance for residents of Maryland, Massachusetts, New Mexico, New York, North Carolina, and Oregon among others. No total number of people affected has been published in the materials reviewed for this page.
The notice says the sender has no evidence of identity theft or financial fraud related to the potentially impacted data and that she is making people aware out of an abundance of caution. She offers a complimentary membership in Experian IdentityWorks Credit 3B, a product described in the notice as designed to detect possible misuse of personal information and to support identity theft resolution. The notice states that enrolling will not hurt a person’s credit score and that a credit card is not required to enroll. It also describes how to place a fraud alert and a security freeze and how to obtain a free credit report.
Email accounts are a common target because they act as a filing cabinet for an organization’s daily business. Staff members send forms, insurance paperwork, billing records, scanned identification, and attachments by email, and those messages often sit in a mailbox for years. When someone takes control of an account, the information inside can be copied in bulk. The notice does not say which categories of information were in the affected files, since that part of the sample is blank, so this page does not guess at them.
The fact that the practice has closed adds a layer of difficulty. When a business shuts down, its records, email systems, and vendor relationships do not always shut down cleanly, and a former owner can end up responsible for notifying people long after daily operations ended. Patients and clients, meanwhile, may no longer have any relationship with the practice and may not recognize the sender, which is one reason these notices sometimes get set aside as junk. A person who is unsure whether a letter is genuine should compare it against the copy on the Massachusetts Attorney General’s site.
People who receive a notice like this should keep in mind that the information may have been in the hands of an unauthorized party for a long time. That makes it all the more sensible to use the protections offered and to stay alert to scams that use real personal details.
When Did This Breach Occur?
According to the notice, Dr. Khmil learned on or about July 15, 2025 that an unauthorized individual accessed a limited number of employee email accounts. After a forensic investigation and data review, she discovered on October 6, 2026 that certain files containing personal information may have been accessed or acquired on July 15, 2025.
The posted sample does not show the date of the letter itself.
What Information Was Breached?
The notice says the information potentially affected includes the recipient’s name and other information, but the list of data types is blank in the sample posted with the Massachusetts Attorney General. The sender has not publicly disclosed a universal list of what was in the files.
Because the incident involved employee email accounts, the files could include a range of personal information that varies from person to person. Readers who received the letter should check it for the specific items that apply to them.
What You Can Do
If you received this notice, consider the following steps.
- Enroll in the complimentary Experian IdentityWorks Credit 3B membership using the activation code and deadline printed in your letter. Your code will not work after the deadline.
- Consider placing a free fraud alert or security freeze with Equifax, Experian, and TransUnion. Note that the notice says a freeze placed before enrolling must be removed before you can sign up for the monitoring service.
- Review your credit reports at annualcreditreport.com and look over bank, card, and insurance statements for activity you do not recognize.
- Be cautious with unexpected emails, texts, and calls that use your personal details, and do not share passwords or financial information in response.
- Report suspected identity theft to the Federal Trade Commission at IdentityTheft.gov, and keep your letter.
