DETROIT, MI- Marko Law, PLLC, and Hurwitz Law PLLC, announced a lawsuit filed against Matthew Weiss, the University of Michigan, the Regents of the University of Michigan, and Keffer Development Services, LLC after Matthew Weiss was able to access the deeply sensitive, private data of student athletes at the University of Michigan.
The lawsuit alleges as follows: The University of Michigan was entrusted with highly sensitive personal data belonging to its student-athletes. It had a duty to safeguard this information and protect it from misuse by employees within the athletic department—individuals who interact with and hold considerable influence over these students’ daily lives. Among those employees was Matthew Weiss, who, between 2015 and 2023, gained unauthorized access to the digital accounts of more than 3,300 student-athletes, including the plaintiffs in this lawsuit. His egregious invasion of privacy has led to a federal indictment with over twenty charges for his nearly decade-long targeting of female college athletes.
The University of Michigan’s failure to properly oversee one of its own—an Offensive Coordinator for the Wolverines football team—was a complete breach of its obligation to protect the confidential data of its student-athletes. Instead of ensuring security, the University allowed Weiss to exploit the private information of female athletes for years and has yet to acknowledge its negligence in failing these women.
Weiss accessed this sensitive data by infiltrating athlete information databases maintained by Keffer Development Services, LLC. He leveraged his role as Offensive Coordinator of the Wolverines’ football team to gain unauthorized entry—an access point made possible by the University’s failure to monitor its own employee.
Both the University of Michigan and Keffer Development Services failed to secure their database containing highly sensitive information, including private photographs and personal details meant only for the athletes themselves. Their lack of safeguards enabled Weiss to engage in a years-long criminal intrusion, violating these women’s fundamental right to privacy.
Due to Weiss’ actions—and the negligence of the University of Michigan, its Regents, and Keffer Development Services—the student-athletes suffered a grave breach of their privacy. For years, their deeply personal information was exploited for the perverse benefit of Matthew Weiss.
“This case is deeply disturbing,” said attorney Jon Marko. “These women simply wanted to compete in their University’s athletic programs. They never imagined that the institution entrusted with their private information would allow it to be compromised, nor that an employee would be able to access some of their most personal data for years. It’s a blatant violation of their fundamental right to privacy.”
The lawsuit, set to be filed in the Eastern District of Michigan, names Matthew Weiss, the University of Michigan, the Regents of the University of Michigan, and Keffer Development Services, LLC, as defendants. Given the vast scope of Weiss’ criminal misconduct, the complaint includes claims under the Computer Fraud and Abuse Act, the Stored Communications Act, and Title IX, along with allegations of civil rights violations, negligent hiring and supervision, invasion of privacy, gross negligence, trespass to chattels, and breaches of Michigan law, including assault, intentional infliction of emotional distress, and violations of the Michigan Identity Theft Protection Act. The plaintiffs are represented by Detroit attorney Jonathan R. Marko of Marko Law and Ann Arbor attorney Noah S. Hurwitz of Hurwitz Law.
