Was this a ransomware attack?

The filing does not say ransomware was involved. We do not label an incident ransomware unless the company’s report says so. Whatever the cause, the steps to protect yourself and the legal question are the same.

What we know

Eversource Energy, a major utility provider, recently experienced a data security incident that compromised sensitive records belonging to its customers and employees. Official filing documents submitted to the Vermont Attorney General on May 21, 2026, confirm that an unauthorized party accessed the company's network and acquired consumer files. Although Eversource Energy has not yet disclosed the exact number of individuals affected, the breach involved confidential personal information that was stored on their systems. When personal information is exposed in a corporate data breach, individuals face a significantly higher risk of targeted phishing attacks, identity theft, and financial fraud. Because this stolen data can be used by bad actors to impersonate you, open unauthorized accounts, or trick you into revealing additional sensitive details, increased vigilance is necessary. Monitoring your financial statements, credit reports, and personal accounts closely is critical to catching and addressing any suspicious activity early. If you received an official notification letter in the mail informing you that your information was compromised in the Eversource Energy data breach, you may be eligible to participate in a class action lawsuit. You can contact our firm today to request a completely free, no-obligation case review with zero upfront fees to help protect your rights.

Can I sue Eversource Energy over the data breach?

How much could a Eversource Energy data breach settlement or claim be worth?
