SAN FRANCISCO, Aug. 28, 2025 /PRNewswire/ -- Schubert Jonckheer & Kolbe LLP is investigating a data breach that led to unauthorized access to the sensitive information of 4,461,511 customers of TransUnion, LLC (TransUnion), an Illinois-based consumer credit reporting agency.

According to the data breach notice filed with the Maine Office of the Attorney General, TransUnion "recently experienced a cyber incident involving a third-party application serving our U.S. consumer support operations," which allowed a third party to gain access to customer information on July 28, 2025.

Although the breach occurred in July 2025, TransUnion did not begin notifying affected individuals until on or around August 28, 2025, which may have violated state and federal laws. TransUnion has not publicly disclosed what information was accessed.

If your personal information was impacted by this incident, you may be at risk of identity theft and other serious violations of your privacy. As a result, you may be entitled to money damages and an injunction requiring changes to TransUnion's cybersecurity practices.

If you received notification of this data breach or are a customer of TransUnion and wish to obtain additional information about your legal rights, please contact us today or visit our website at https://www.classactionlawyers.com/transunion.
