A former NFL and university football coach faces federal charges after allegedly accessing 3,300 student accounts to steal intimate photos and videos.

Matt Weiss, 42, was indicted on 24 counts, including 14 for unauthorized computer access and 10 for aggravated identity theft, according to the U.S. Attorney’s Office for the Eastern District of Michigan. Weiss, who was fired as the University of Michigan’s co-offensive coordinator in January 2023, allegedly exploited university databases to gain access to student-athlete accounts.

Authorities say Weiss infiltrated a third-party database containing records from over 100 colleges and universities. He allegedly compromised staff credentials with elevated access, allowing him to steal personally identifiable information (PII) and medical data of more than 150,000 athletes. According to the indictment, he cracked encrypted passwords and gathered personal details such as maiden names and birthplaces to reset or guess login credentials.

Matt Weiss was a former coach at Michigan’s college football program and an alumnus of Vanderbilt University.

Using this method, Weiss allegedly accessed 2,000 student accounts, specifically targeting female student-athletes’ social media, email, and cloud storage to download private images and videos. He also reportedly exploited authentication vulnerabilities to breach the accounts of 1,300 additional students and alumni.

Federal court records do not list an attorney for Weiss, and it remains unclear if he is in custody. A phone number linked to him was not immediately responsive to inquiries from NBC News. The University of Michigan declined to comment, referring questions to the U.S. Attorney’s Office.

Unauthorized computer access charges carry a maximum five-year federal prison sentence per count, while aggravated identity theft convictions come with a mandatory two-year minimum. Weiss joined Michigan’s coaching staff in 2021 after 12 seasons with the Baltimore Ravens and previous experience at Stanford University. His tenure overlapped with head coach Jim Harbaugh at both Michigan and Stanford and with Harbaugh’s brother, John, who has led the Ravens since 2008.
