What Happened?
Quattro Business Support Services, Inc. was listed in a Vermont Attorney General breach report summary published September 9th, 2026. According to the company’s own notification letter and state attorney general filings, an unauthorized actor accessed certain files between November 11th and November 19th, 2025. Quatrro discovered the incident on December 7th, 2025, and completed its review of the affected files on February 25th, 2026. Notification letters were mailed to affected individuals beginning March 23rd, 2026. The breach was also reported to the attorneys general of Maine and New Hampshire; the Vermont filing on September 9th, 2026 appears to represent a later state-level report of the same incident. The total number of affected individuals has not been publicly disclosed. UpGuard classified the incident as medium severity. No specific threat actor has been publicly identified, and no ransomware group has been linked to this incident.
The types of personal information involved varied by individual and included names, Social Security numbers, driver’s license numbers, passport numbers, payment card numbers, financial account numbers, and health insurance policy numbers. As of September 2026, multiple law firms — including Cole & Van Note, Migliaccio & Rathod LLP, Srourian Law Firm, Shamis & Gentile P.A., Finkelstein Blankinship Frei-Pearson & Garber LLP, Levi & Korsinsky LLP, and Dapeer Law — are investigating potential class action lawsuits, though no filed complaint has been confirmed.

What Should You Do?
If you received a notification letter from Quattro Business Support Services, Inc. or ContinuServe, take advantage of any identity theft protection or credit monitoring enrollment the company has offered, and act before any enrollment deadline stated in your letter. Regardless of whether you received a letter, you can place a free fraud alert or credit freeze with the three major credit bureaus — Equifax, Experian, and TransUnion — to limit unauthorized access to your credit. Review your financial account statements closely for unfamiliar charges and obtain your free annual credit reports at AnnualCreditReport.com. Because health insurance policy numbers were among the data types exposed, also review any Explanation of Benefits statements you receive and request a copy of your medical records to check for unfamiliar services or claims. If you suspect your information has been misused, visit IdentityTheft.gov to report it and get a personalized recovery plan.
