Boston Green Company, a Lakeville, Massachusetts-based environmental contractor, has notified state regulators and affected individuals of a data security incident involving unauthorized access to an employee email account. Companies that maintain sensitive personal information in their business systems have a responsibility to protect it, and when that data is exposed, the people affected deserve a clear explanation and a path to hold the responsible party accountable.
Boston Green Company’s Data Breach Investigation
According to a notification letter filed with the New Hampshire Attorney General’s Office, Boston Green became aware of suspicious activity on its email system on May 19, 2026, involving an unusually high volume of email activity. The company promptly launched an investigation with the assistance of third-party computer forensic specialists to determine the full nature and scope of the activity.
The investigation determined that an unknown individual had unauthorized access to an employee’s email account between May 7, 2026, and May 19, 2026, a window of roughly two weeks. Boston Green then conducted a review of the impacted emails to determine what information was contained within them and to whom it belonged. That review concluded shortly before the company began notifying affected individuals on August 27, 2026, roughly three months after the intrusion was first detected.
Email account compromises like this one are among the most common types of data breaches reported to state regulators, in part because email accounts often accumulate years of sensitive attachments, forwarded documents, and correspondence that employees never intended to be treated as a security risk. Once an attacker gains access to a mailbox, sorting through months or years of messages to identify exactly which emails contained sensitive personal information is a labor-intensive forensic process, which helps explain why the gap between initial detection and final notification in cases like this one is often measured in months rather than days.
The information Boston Green identified as potentially exposed, names, Social Security numbers, and driver’s license numbers, is a combination that is especially valuable to identity thieves, since it can be used to open new financial accounts, apply for government benefits, or file fraudulent tax returns in a victim’s name. Regulatory notification laws, including the New Hampshire statute that prompted this filing, exist precisely so that affected individuals learn of this kind of exposure while there is still time to take protective steps such as placing a credit freeze or fraud alert.
Boston Green’s New Hampshire filing reflects a small number of residents in that state, but the same underlying email compromise affected residents of other states as well, including a separate cohort of Rhode Island residents referenced in the company’s own notification materials. It is common for a single security incident to trigger multiple state-specific regulatory filings with different resident counts in each one, rather than a single nationwide total, since most state breach notification laws require separate reporting based on where affected individuals reside.
