4.4 Million Exposed in TransUnion Data Breach—Take Action!

TransUnion Data Breach Exposes Data of 4.4 Million—Another Reminder to Freeze Your Credit Yesterday!

By Alexander Hernandez, J.D., Professor, and Author of Consumer Bankruptcy Law (Routledge).

The TransUnion data breach occurred on  July 28, 2025, but public notification began on August 26 due to a regulatory filing with the Maine Attorney General’s Office.

According to the filing, the exposed data includes names and personal identifiers that are sensitive information. While the type of sensitive information was not listed, it likely applies to Social Security numbers, government IDs, or financial account details. TransUnion has sent notices to those affected.

What You Should Do (Preferably Before Reading This)

TransUnion is offering two years of free credit monitoring and identity theft protection via its *myTrueIdentity* service, which includes: daily credit report monitoring, fraud alerts, and up to $1 million in identity theft insurance.

As I’ve said before, reacting to a breach is not a substitute for proactive freezing. Once your data is exposed, it might be too late. Consider placing a credit freeze with all three bureaus (TransUnion, Equifax, Experian). It’s free, reversible, and far more effective than waiting for a fraud alert to ping your inbox.

Just to give you an idea of how well and quickly it works, applying for a new mortgage about one month ago, I received a call from the lender asking if I had a credit freeze. I said to give me ten minutes. I removed the freeze, and once I received notification that my credit was “pulled,” I froze it again!

It’s these little steps that you can take to protect yourself!
