LANSING – Attorney General Dana Nessel urges Michigan residents who believe they were affected by the data breach announced by T-Mobile in August 2021 to take appropriate steps to protect their information from identity theft.

On August 17, T-Mobile reported a massive data breach compromising the sensitive personal information of millions of current, former and potential T-Mobile customers. The breach affected more than 53 million people, including more than 1.1 million Michigan residents. Among other categories of information affected, millions of people have had their names, dates of birth, social security numbers and driver’s license information compromised.

Nessel is involved in a multi-state coalition of attorneys general currently reviewing the breach and whether T-Mobile had appropriate safeguards in place to protect personal information.

Recently, a large subset of the information compromised in the breach was for sale on the dark web, a hidden part of the internet where cybercriminals buy, sell and track personal information. Many people have since received alerts through various identity theft protection services advising them that their information has been found online in connection with the breach, confirming that those affected are at increased risk of identity theft.

Nessel is reissuing its Data Breaches: What To Do Next Consumer Alert with more information about protecting your personal information in response to the latest developments.

“Anyone who has received notice from T-Mobile regarding this breach should take action to address potential identity theft,” Nessel said. “While we can’t prevent bad actors from gaining access to your information – especially once it’s offered for sale on the dark web – there are ways to protect yourself if your information has been compromised.”

She urges anyone who thinks they may have been impacted by T-Mobile’s breach to take the following steps to protect themselves:

  • Watch your credit. Credit monitoring services track your credit report and alert you whenever a change is made, such as a new account or a large purchase. Most services will notify you within 24 hours of any changes to your credit report.
  • Consider placing a free credit freeze on your credit report. Identity thieves will not be able to open a new credit account in your name while the freeze is in place. You can place a credit freeze by contacting each of the three major credit bureaus:
    • Equifax | online or by calling 888-766-0008
    • Experian | online or by calling 888-397-3742
    • Trans Union | online or by calling 800-680-7289

  • Place a fraud alert on your credit report. A fraud alert tells lenders and creditors to take extra steps to verify your identity before issuing credit. You can place a fraud alert by contacting any of the three major credit bureaus.
  • Additional Resources. If you think you’ve been the victim of identity theft, visit the Federal Trade Commission’s website for information on how to report and recover, or contact the Attorney General’s office for assistance.

You can learn more about state identity theft resources on the Department of the Attorney General’s website.

The Department provides a library of resources that consumers can consult at any time on a variety of topics.
