U.S. Duct Reports Unauthorized System Access to New Hampshire AG

U.S. Duct, a company specializing in industrial HVAC components and ductwork systems, formally reported a data breach to the New Hampshire Attorney General on April 24, 2026. This filing indicates that unauthorized access was gained to the company's internal computer systems. The investigation into the scope and nature of this security incident is currently underway.

The official public records concerning this breach do not specify the exact types of personal information that were exposed during the unauthorized access. While U.S. Duct, like many industrial businesses, typically handles various forms of sensitive personal data for employees, contractors, and clients, the specific categories of data involved in this incident remain unconfirmed in the public disclosure.

Individuals who have received a direct notification letter from U.S. Duct are encouraged to review its contents thoroughly. This letter is the primary source for understanding what specific personal information belonging to them may have been affected and any identity protection services the company might be offering.

To help protect against potential misuse of exposed data, affected individuals should consider placing a fraud alert on their credit files and regularly monitoring financial statements for any unusual activity. It is also wise to be cautious of unsolicited communications, especially those requesting personal or financial details. These general steps are widely recommended in response to data security incidents.
