AG Nessel Reissues Consumer Alert on Data Breaches Following TransUnion Cyber Incident

Published Date: Sep 22, 2025

Michigan Attorney General Dana Nessel is reissuing her consumer alert on data breaches following a recently revealed cyber incident at TransUnion that impacted more than 4.4 million people in July. The breach, which involved unauthorized access through a third-party application, compromised personal data, including names, Social Security numbers, and dates of birth. According to TransUnion, no credit information was accessed.
“Michigan constantly rates among the top 20 states for identity theft reports, and data breaches like these only increase the risks for consumers,” Nessel said. “This is why I have long supported stronger data breach notification laws that would give us greater ability to track breaches, hold companies accountable, and better protect Michigan consumers. I urge residents to be vigilant and take advantage of the resources available to help safeguard their personal information.”
