Matt Weiss Data Breach Investigation: Know Your Legal Options

When your personal information is stolen, it’s not just data—it’s your identity, your safety, and your peace of mind. For many, the emotional aftermath of a data breach is immediate: anxiety, fear of financial ruin, and a profound sense of betrayal. That’s exactly what countless individuals are now facing following the reported data breach linked to Matt Weiss.

So who is Matt Weiss, and why does it matter? Matt Weiss is a Michigan-based entrepreneur who previously worked in sports analytics and AI development. Recently, disturbing revelations surfaced that link Weiss to a significant data breach affecting a wide swath of individuals—potentially including sensitive financial and personal data. While details are still unfolding, early reports suggest that this wasn’t just a minor slip-up—it may have involved gross negligence or unlawful access to private information.

At Marko Law, we take these cases seriously. A breach like this isn’t just a tech issue—it’s a civil rights and privacy issue. If you or someone you love received a breach notification or suspect your personal data may have been compromised, you cannot afford to wait.

What We Know About the Matt Weiss Data Breach

Timeline of the Breach

The breach tied to Matt Weiss wasn’t a single moment—it was a calculated, years-long violation of trust. From 2015 through January 2023, Weiss allegedly accessed sensitive data through a software platform used by more than 100 college athletic departments. The University of Michigan began investigating in December 2022, when suspicious activity on a student-athlete’s account was reported. By January 2023, Weiss was fired. In March 2025, federal authorities dropped the hammer—charging him with multiple counts of computer hacking and identity theft.

What Kind of Data Was Exposed?

This wasn’t just emails and usernames. Weiss allegedly accessed and exploited:

• Full names, addresses, and birthdates
• Social Security numbers
• Private medical and psychological records
• Social media and email logins
• Cloud accounts containing intimate images and videos

How Many People Were Impacted?

At least 150,000 athletes had their personal or medical data compromised.

Over 3,300 victims—mostly female college athletes—had their accounts directly accessed. That means thousands of women may have had their most personal information viewed, copied, or stolen without ever knowing it.

How Has the Public Responded?

The reaction has been explosive. National headlines painted Weiss as a predator hiding behind a football headset. The University of Michigan has come under fire for its silence—waiting over two years to inform the public, despite knowing sensitive data was at risk. The situation echoes past institutional failures, drawing sharp criticism and comparisons to the Nassar and Anderson scandals.

What Victims Are Being Told

Some have received formal notices—mainly through the Department of Justice’s Victim Notification System. Others have heard nothing at all. There are still athletes out there—former students, now adults—who have no idea their intimate data was stolen. That silence is part of the trauma.

The Legal Side: What Counts as a Data Breach in Michigan

Michigan’s Identity Theft Protection Act: Know Your Rights

Michigan’s Identity Theft Protection Act (ITPA) makes it clear: if a company collects your personal information, they are legally required to protect it. That includes your:

• Social Security number
• Driver’s license number
• Medical or financial information
• Login credentials

Under the ITPA, if this information is accessed without permission, and there's a risk of identity theft or fraud, the company must notify you. And if they fail to act responsibly, they could be on the hook for damages.

Negligence: When “Oops” Becomes a Lawsuit

If someone—like Matt Weiss—accesses private data they had no right to, that’s unauthorized access. But the legal spotlight doesn’t just fall on the hacker. It also shines on the institutions that allowed it to happen.

If the University of Michigan, Keffer Development Services, or any other entity:

• Failed to secure their platforms,
• Ignored warning signs,
• Didn’t notify victims in a timely manner,

They could be liable for negligence. That means failing to do what a reasonable organization should do to keep your information safe.

Federal Protections: CFAA and HIPAA

This breach doesn’t just raise state issues. It could trigger federal laws, including:

• Computer Fraud and Abuse Act (CFAA): This law criminalizes unauthorized access to protected computers. It’s the statute Weiss is now charged under. Victims may also pursue civil claims if they suffered financial loss or emotional harm from the intrusion.
• HIPAA Violations: If the stolen data includes medical records from healthcare providers or third-party vendors, this could also fall under Health Insurance Portability and Accountability Act protections. HIPAA mandates the safeguarding of health information—and violations can carry serious consequences.

The Legal Duty to Protect Your Information

Whether it’s a university, tech provider, or employer—if they collect your sensitive data, they owe you a legal duty of care. That means:

• Keeping your data secure
• Limiting access only to authorized users
• Acting quickly if there’s a breach

When that duty is breached and you’re harmed, you may have a legal claim.

Your Rights If Your Data Was Exposed

You Have the Right to Be Notified

Under the Michigan Identity Theft Protection Act, if your sensitive data was exposed in a breach that could lead to identity theft or fraud, you have the right to be notified—promptly and clearly. That notice must include:

• What was stolen
• When it happened
• What you can do next

You Have the Right to Sue for Damages

If you’ve suffered harm as a result of the breach—financial fraud, identity theft, emotional trauma, reputational damage—you may be entitled to compensation.

What you can potentially recover:

• Out-of-pocket costs (credit monitoring, account recovery, legal fees)
• Lost income
• Emotional distress
• Future identity protection

Even if you haven’t yet seen fraudulent charges, you may still have a valid claim for the stress and risk imposed on you without your consent.

Class Action Lawsuits: Strength in Numbers

Because this breach impacted thousands of people, including many with similar injuries, it opens the door to class action litigation.

Class actions allow victims to come together, amplify their voices, and take on major institutions without the burden of fighting alone. They can also:

• Drive public accountability
• Force stronger data security policies
• Result in large settlements or court awards

What You Can Do Now

Freeze Your Credit

A credit freeze stops thieves from opening new accounts in your name. It's free and easy to set up with the three major credit bureaus:

• Equifax: equifax.com
• Experian: experian.com
• TransUnion: transunion.com

Monitor Your Accounts

Watch all financial activity like a hawk:

• Bank and credit card statements
• Loan accounts
• Medical billing
• Social media and email login attempts

File an FTC Identity Theft Report

If you suspect or know that your identity has been misused, go to IdentityTheft.gov and file a report with the Federal Trade Commission (FTC). This gives you:

• A recovery plan
• Official documentation for creditors
• Legal standing if you need to dispute fraudulent activity

Save Every Piece of Evidence

Do not delete emails, letters, or screenshots related to the breach. Keep:

• FBI or DOJ notifications
• Correspondence from the University of Michigan or any data processors
• Any notes about suspicious financial or digital activity

Contact a Lawyer—Especially if Negligence is Involved

If any institution failed to:

• Protect your data
• Notify you in a timely way
• Take accountability after the fact

—they may be legally responsible. That includes universities, third-party vendors like Keffer Development Services, and even individuals like Weiss himself.

An experienced attorney can help you:

• Understand your legal rights
• Join or initiate legal action
• Maximize your chances of real compensation

You Deserve More Than an Apology

Let’s be clear: what happened in the Matt Weiss data breach wasn’t just about stolen files or hacked passwords. This was an invasion of privacy—an attack on your identity, your dignity, and in many cases, your most intimate moments.

Data breaches like this cut deep. They expose more than information—they expose people.

And when institutions stay silent, delay accountability, or fail to protect you in the first place, it’s not just wrong—it may be unlawful.

If your data was compromised, you may be entitled to real compensation for what you’ve lost—and for the pain it caused. Emotional distress, financial damage, and betrayal of trust all matter.
