Matthew Weiss, 42, the former co-offensive coordinator at the University of Michigan, is facing federal charges following allegations that he unlawfully accessed the online accounts of around 3,300 people to download intimate images and videos, primarily targeting female athletes. The charges, which include 14 counts of unauthorized access to computers and 10 counts of aggravated identity theft, were announced earlier this week.

University of Michigan Data Breach Details

According to the indictment, between 2015 and January 2023, Weiss gained unauthorized access to student athlete databases from more than 100 colleges and universities that were maintained by a third-party vendor. These databases contained personal and medical data of over 150,000 athletes.

Using the stolen information from these databases and additional online research, Weiss was able to gain access to the social media, email, and cloud storage accounts of more than 2,000 targeted athletes. Additionally, Weiss also illegally accessed the accounts of over 1,300 students and alumni from universities across the United States.

Once inside these accounts, Weiss allegedly downloaded personal, intimate digital images and videos that were never intended to be shared beyond the individuals’ intimate partners.

What Information Was Compromised?

The information exposed in the breach may vary by individual, but it could include the following:

  • Name

  • Address

  • Social Security number

  • Email
  • Driver’s license number

  • Intimate videos and images

How to Know if You Were Affected

If you received a data breach notification from University of Michigan, your personal information may have been compromised. While most victims are officially notified through a “Notice of Data Breach” in the mail, the consequences—such as fraudulent transactions and identity theft—can begin long before the notice arrives.

Steps to Take if You Were Affected by the University of Michigan Data Breach

Stay Alert for Phishing Scams
Scammers may exploit the data breach by posing as University of Michigan. Be cautious of unexpected emails, texts, or calls requesting personal information. When in doubt, verify communications directly with the company through official channels.

Monitor Your Credit and Financial Accounts
Regularly check your bank statements, credit card activity, and credit reports for unauthorized transactions. Set up account alerts to detect suspicious activity early. Take advantage of free credit reports and review them carefully for unfamiliar accounts or discrepancies.

Consider Freezing Your Credit
For added security, request a credit freeze from all three major credit bureaus. This prevents new accounts from being opened in your name while still allowing you to use existing credit. You can temporarily lift the freeze when necessary if applying for credit.
