Relief for Vermont Workers: Most Dodged Deadly Data Breach at Teamsters' Health Union
If you live in Vermont, and your information was compromised in this breach, you should have received a formal letter in the mail from TeamstersCare.
While tens of thousands of union members across New England are being urged to check their credit reports after a major data breach, it appears the vast majority of Vermont workers were not affected. A cybersecurity incident at the Boston-based Teamsters Union 25 Health Services & Insurance Plan exposed highly sensitive personal data, but its impact within the Green Mountain State is expected to be minimal.
The breach targeted the health plan known as TeamstersCare, which primarily serves members of Teamsters Local 25 in Massachusetts. According to a notice from the organization, a cybercriminal gained access to its network on August 1, 2025, and potentially copied files containing a trove of personal information.
The compromised data includes names, Social Security numbers, medical and health insurance information, and member ID numbers. The theft of such data puts affected individuals at a significant, long-term risk of identity theft and medical fraud.
The organization reported that at least 19,935 people in Massachusetts and 1,521 in New Hampshire were impacted. In contrast, a notice filed with the Maine Attorney General listed only 13 affected residents in that state.
How Vermonters Will Know and Why the AG Did Not Issue a Warning
For Vermonters, the key takeaway is that notifications are direct. If your information was compromised in this breach, you would have received a formal letter in the mail from TeamstersCare. According to the company’s timeline, these letters were sent out on September 3, 2025. If you did not receive a letter, you are almost certainly not part of the breach.
The Vermont Attorney General’s office has not issued a statewide warning because the number of affected residents does not appear to meet the legal threshold for a broad public alert. Under Vermont's Protection of Personal Information law, a company must notify the Attorney General of any breach, but a public announcement from the state is generally reserved for incidents affecting more than 1,000 Vermonters. The number of Vermonters impacted by the TeamstersCare breach is estimated to be very low, likely in the dozens, because most union members here belong to Vermont’s own Teamsters Local 597, not the Boston-based Local 25.
The only Vermonters likely to be affected are those who work for a small number of national companies, such as UPS or ABF Freight, and are enrolled in the larger, regional health plan administered by TeamstersCare.
Steps for Those Who Received a Letter
For the small number of Vermonters who did receive a notification, immediate action is recommended.
Enroll in Free Credit Monitoring: TeamstersCare is offering complimentary identity protection services through TransUnion Cyberscout. Instructions for enrollment are included in the notification letter.
Monitor Your Accounts: Carefully review all financial, insurance, and medical statements for any signs of fraudulent activity. Report any suspicious charges or claims to the relevant institution immediately.
Place a Fraud Alert: Contact one of the three major credit bureaus (Equifax, Experian, or TransUnion) to place a free, one-year fraud alert on your credit file. This makes it harder for criminals to open new accounts in your name.
Be Wary of Scams: Be on alert for phishing emails or phone calls. Scammers can use stolen data to make their attempts to trick you sound more convincing.
According to consumer protection experts, individuals affected by such breaches may be eligible for compensation. National law firms are already investigating the incident for a potential class-action lawsuit to cover damages, such as out-of-pocket expenses and time spent securing personal accounts.
