DUO Broadband Notifies New Hampshire Customers of Data Incident

DUO Broadband (Duo County Telephone Cooperative Corporation, Inc. and Cumberland Cellular, LLC) recently disclosed a data security incident affecting its customers. On May 15, 2025, the company filed a report with the New Hampshire Attorney General, confirming that their systems were accessed without authorization. This news comes to you if you've received an official notification letter from DUO Broadband.

Receiving a data breach notification letter means that your personal information was likely involved in this security event. While the exact details of what information was accessed can vary for each individual, the letter serves as formal notice that your data may be at risk. DUO Broadband is currently investigating the full scope of the incident to understand precisely what occurred.

It's important to take proactive steps to protect your personal information after any data breach. Consider placing a fraud alert on your credit files to make it harder for identity thieves to open new accounts in your name. You can do this by contacting one of the three major credit bureaus.

Regularly review your financial statements and credit reports for any suspicious activity or unauthorized transactions, reporting anything unusual immediately. Vigilance now can help prevent future complications, as identity theft can sometimes take months to surface.

Be extra cautious about unsolicited communications, especially emails or calls asking for personal details. Cybercriminals often use information from breaches to craft convincing phishing attempts. Remember that legitimate companies will rarely ask for sensitive data like passwords or account numbers via email or phone.

If you find any evidence of misuse of your information, or if you simply have questions about your legal options, it can be helpful to discuss your situation. An evaluation of your specific circumstances might offer clarity on potential next steps. A free case review can help you understand if you have grounds for legal action or need further assistance.
