TransUnion Data Breach: Lawsuit Investigation
Attorneys working with ClassAction.org are looking into whether a class action lawsuit can be filed in light of the TransUnion data breach.
As part of their investigation, they need to hear from individuals who received a notice stating they were impacted.
TransUnion Security Incident: What Happened?
On August 27, 2025, credit reporting agency TransUnion reported a data breach impacting 4,461,511 individuals and is now sending written notices to those affected.
According to sample notice letters (seen below), the TransUnion data breach involved unauthorized access to personal information that was stored on a third-party application serving U.S. consumer support operations. Though the sample notice did not specify what consumer information was exposed in the incident, the company said no credit reports or "core credit information" was involved. According to a report provided to the Texas Attorney General's Office, consumers' names, Social Security numbers and dates of birth were affected.
TechCrunch reports that TransUnion stores the financial data of more than 260 million Americans and that it is currently unknown who is responsible for the data breach.
According to a report submitted to the Maine Attorney General's Office, the TransUnion data breach occurred on July 28, 2025 and was discovered two days later.
What You Can Do After the TransUnion Data Breach
If your information was exposed in the data breach, attorneys want to hear from you. You may be able to start a class action lawsuit to recover compensation for loss of privacy, time spent dealing with the breach, out-of-pocket costs, and more.
A successful case could also force TransUnion to ensure it takes proper steps to protect the information it was entrusted with.
