Matt Weiss University of Michigan Data Breach Lawsuit

If You Were a Student-Athlete Between 2015–2023, Your Privacy May Have Been Violated

Thousands of athletes trusted the University of Michigan with their most sensitive information. But that trust was broken when former football coach Matt Weiss unlawfully accessed private data, including:

  • Personal medical records
  • Confidential photos and videos
  • Email and social media accounts

Marko Law has filed a class action lawsuit on behalf of affected athletes. If you were a student-athlete during this time, you may be entitled to compensation.

What Happened?

According to the U.S. Department of Justice, Matt Weiss gained unauthorized access to private digital accounts of more than 3,300 University of Michigan athletes. These accounts contained deeply personal data that no coach or staff member should have seen.

Worse yet, this breach was made possible by the University's failure to enforce basic cybersecurity protocols and monitor employee access to student information.

Do You Qualify?

You may qualify for legal action if:

  • You were a U of M student-athlete between 2015–2023
  • You used the Keffer Development Athletic Trainer System (ATS)
  • You are concerned your privacy was violated

Big shoutout to the Marko Law squad. Gasper was an absolute assassin in the best possible way, and trust me, that's a high compliment coming from me. John Eads and Gasper tag-teamed those negotiations like champs. I'll be sending clients your way for the foreseeable future.
