Background

What happened in the Electric Research and Manufacturing Cooperative data breach

Electric Research and Manufacturing Cooperative, located in Dyersburg, Tennessee, says it identified unusual activity in its network on August 7, 2026. In the filing, its counsel refers to the company as "ERMCO." According to the company's notice letter, an investigation with the assistance of cybersecurity professionals determined that between August 7, 2026, and August 11, 2026, an unauthorized person accessed the network and acquired copies of certain files.

The company reviewed the information involved. On September 9, 2026, it identified that the files contained individuals' names and one or more of the following: Social Security number, driver's license or state identification card number, passport number, medical information or health insurance information. The New Hampshire filing lists the same categories: Social Security number, driver's license or state identification card number, passport number, medical information and health insurance information. According to the letter from the company's counsel to the New Hampshire Attorney General, the company began mailing notification letters by First-Class mail on September 25, 2026.

Electric Research and Manufacturing Cooperative reported 6,490 affected individuals to the Indiana Attorney General, including 5 Indiana residents. Its New Hampshire filing covers 4 New Hampshire residents. The letter offers complimentary Kroll identity monitoring services, and the company says it notified law enforcement. Whether the company's security practices before the incident met legal standards is among the issues being evaluated.
