What Happened?
According to the Maine Attorney General filing, Eversource Energy reported an external system breach described as hacking. The filing indicates the event occurred on April 14, 2026 and was discovered on April 27, 2026. A public listing appeared on the Maine portal on May 21, 2026, and written consumer notices were reportedly mailed several days later. Public regulatory summaries are often abbreviated, so the filing does not fully explain in public-facing detail how the incident unfolded or whether every affected person had the same information at issue.
What Information Was Exposed?
The public filing uses abbreviated language indicating that a name or other personal identifier was involved in combination with protected information. The structured incident data provided for this matter states that the information may have included names, Social Security numbers, driver’s license numbers, and financial account numbers. Because public summaries can shorten the wording from a full notice letter, affected individuals should review their own notice carefully to confirm which data elements, if any, were identified for them.
What Should You Do Next?
- Read your notice closely. Confirm what information the letter says may have been involved and keep a copy for your records. If you need additional notice-related information, the Maine filing lists a contact number of (617) 348-1732.
- Enroll in any offered identity protection. The filing states that 24 months of Identity Guard services from IDX were offered. If your letter includes an enrollment code or deadline, consider using it promptly.
- Monitor financial accounts and credit activity. Watch bank accounts, payment cards, and credit reports for unfamiliar activity, especially if Social Security or financial account information may have been involved.
- Consider a fraud alert or credit freeze. If highly sensitive data may have been affected, a fraud alert or freeze can make it harder for someone to open new credit in your name.
- Report suspicious activity quickly. If you see signs of identity theft, report them right away through IdentityTheft.gov and to the relevant financial institutions or credit bureaus.
- Document your time and losses. Save letters, screenshots, account statements, and notes about calls or expenses. If you want to understand your options, you can fill out the form on this page to contact Strauss Borrelli PLLC for a review.
Your Legal Rights
If your personal information was involved in a reported data incident, you may have legal rights depending on the facts, the notice language, and the law that applies where you live. In some situations, affected individuals may seek relief related to out-of-pocket expenses, unreimbursed fraud losses, time spent responding to the incident, or the cost and burden of protecting their identity. A legal review can also examine whether the response and notice process appear consistent with applicable requirements. This is general information only and not individualized legal advice.
