Sites Medical LLC has notified individuals that a recent data security incident may have affected their personal information. A sample of the notice letter was filed with the Massachusetts Attorney General’s office as part of its November 2026 list of data breach notification letters.
Any company that collects and stores personal information takes on a responsibility to protect it, and people who receive a breach notice have a right to understand what happened and what options they have.
Sites Medical’s Data Breach Investigation
Sites Medical LLC, which refers to itself in its notice as Sites Medical, is writing to individuals about what it calls a recent data security incident that may have affected their personal information. The notice was filed with the Massachusetts Attorney General’s office and is listed among the November 2026 data breach notification letters on the state’s website. The letter is sent on the company’s behalf through Cyberscout, a TransUnion company that provides breach response and identity protection services.
The filed letter is notably short on specifics. It does not say when the incident happened or when it was discovered, and it does not explain how an unauthorized party may have gotten access. It also does not list the types of personal information involved, and it does not state how many people were affected in total. The copy on file with Massachusetts is a sample form letter with placeholder fields for the recipient’s name, the mailing date and the activation code, so each recipient may see slightly different details in the letter that actually arrives in the mail.
What the letter does say is that Sites Medical has no evidence of the misuse or attempted misuse of any potentially impacted information. Out of an abundance of caution, the company is offering 24 months of complimentary identity protection services through Cyberscout. According to the letter, those services include 24 months of credit and dark web monitoring, a $1 million identity fraud loss reimbursement policy, and fully managed identity theft recovery services. Recipients must enroll within 90 days of the date of the letter, and the enrollment requires an internet connection and an email account.
The letter also walks recipients through rights that Massachusetts law gives to consumers. Under that law, a person has the right to obtain any police report filed about the incident, and a victim of identity theft has the right to file a police report and get a copy of it. The letter explains how to place a security freeze on a credit report with each of the three major consumer reporting agencies, Equifax, Experian and TransUnion, and it warns that a freeze can delay or interfere with approval of new loans, credit, mortgages, employment, housing or other services.
Because Sites Medical has not published details, it is worth being clear about what is and is not known. The company has confirmed through its own notice that an incident occurred and that personal information may have been affected. It has not publicly stated what kind of incident it was, which systems were involved, or which categories of information were exposed. This page will reflect only what the company and the regulators have actually disclosed, and it does not guess at details that have not been made public.
When a company says personal information may have been affected without naming the data types, the practical risk depends heavily on what was actually stored. Companies that handle customer, vendor or employee records commonly hold names, mailing addresses, contact details and account information, and some also hold government identification numbers, financial details or health-related information. A notice that offers credit monitoring, dark web monitoring and identity theft recovery services, as this one does, suggests the company considers identity-related risk to be a reasonable concern, although the letter itself does not confirm which identifiers were involved.
State breach notification laws generally require a company to notify affected people without unreasonable delay once it determines that personal information was involved. Many states also require the company to send a copy of the notice to the attorney general when residents of that state are affected, which is why the letter appears in the Massachusetts list. Companies also commonly bring in an outside vendor to mail notices and set up a call center and monitoring enrollment, which matches the Cyberscout arrangement described in this letter.
People who receive a notice from Sites Medical should read it closely and keep it. The letter is the primary record showing that a particular person was among those notified, and it carries the unique activation code needed to enroll in the offered services. Anyone who has done business with Sites Medical, or who has other reason to think their information may be involved, should watch their mail for a letter from the company and be cautious about unexpected calls, texts and emails that refer to the incident.
Because the notice is silent on key details, more information may emerge later, including from other state regulators or from the company itself. Anyone affected can contact the toll-free number printed in the letter to ask the company directly what information of theirs was involved.
When Did This Breach Occur?
Sites Medical has not publicly disclosed when the incident occurred or when it was discovered. The notice describes it only as a recent data security incident, and it does not give an incident date range or a discovery date.
The company’s notification letter was filed with the Massachusetts Attorney General’s office in November 2026, and the sample letter on file carries a placeholder date for that month. Recipients have 90 days from the date of their individual letter to enroll in the complimentary identity protection services, so the date on your own letter matters for that deadline.
What Information Was Breached?
The notice does not say which types of personal information were involved. It states only that the incident may have affected the recipient’s personal information, and it does not list specific data elements such as Social Security numbers, financial account details or health information.
Sites Medical has also not stated how many people were affected. The letter you receive is the best indication of whether your information was involved, and you can ask the company’s call center through the number in the letter what information of yours was affected.
What You Can Do
If you received a notice from Sites Medical, or you believe you may be affected, consider the following steps.
- Enroll in the 24 months of complimentary credit and dark web monitoring offered through Cyberscout, using the activation code in your letter, and do so within 90 days of the date on the letter.
- Review your credit card, bank and other account statements regularly, and report anything you do not recognize to the institution right away.
- Request your free credit reports from Equifax, Experian and TransUnion at annualcreditreport.com and look for accounts or inquiries you did not authorize.
- Consider placing a free fraud alert or a security freeze with each of the three credit bureaus, keeping in mind that a freeze can delay new credit applications.
- Be cautious with unexpected calls, texts or emails that mention Sites Medical or the incident, even if the sender seems to know personal details about you.
- Call the toll-free number in your letter if you want to ask what information of yours was involved, and keep your letter and any records of suspicious activity.
