Princeton University Data Breach Lawsuit

Princeton University recently announced a data breach that compromised a database containing personal information about alumni, donors, faculty, staff, students, parents, and other members of the University community. Although sensitive data such as Social Security numbers and financial information was not believed to be involved, the breach exposed other biographical details. Affected individuals may be eligible for compensation through a class action lawsuit.

Princeton University’s Data Breach Investigation

On November 10, 2025, Princeton University discovered that an outside actor had compromised one of its databases. The database contained biographical information related to alumni, donors, faculty, staff, students, and other members of the University community, primarily used for fundraising and alumni engagement activities. While the University believes that no passwords, Social Security numbers, credit card information, or bank account records were exposed, the precise nature of the accessed data remains under investigation.

In response to the breach, Princeton University acted swiftly to notify affected individuals. On November 15, 2025, the University sent notification emails to everyone with a valid email address in the affected database. However, individuals who did not have a valid email address in the database, or whose email service may have rejected or redirected the notification to spam, may not have received the message.

The University continues to work with cybersecurity experts to understand the full scope of the incident and enhance its security measures.

When Did This Breach Occur?

The data breach was discovered on November 10, 2025, when unusual activity was detected in the University’s database. Notification emails were sent to affected individuals starting November 15, 2025.

What Information Was Breached?

The compromised database contained biographical information that may include:

• Names

• Contact information

• Alumni, donor, and student data

• Faculty and staff information

While sensitive data such as Social Security numbers, passwords, credit card details, and bank account information were not believed to be involved, the breach still exposed other personal data. Affected individuals should be aware of the potential risks of identity theft and phishing attempts as a result of the breach.

What You Can Do

If you were impacted by the Princeton University data breach, it’s important to take steps to protect your personal information:

1. Monitor Your Email for Phishing Attempts: Be cautious of suspicious emails claiming to be from Princeton University. The University will never ask for sensitive information like Social Security numbers, passwords, or bank account details via email, text, or phone.

2. Verify Communications: If you receive an email or message from Princeton University that you find suspicious, verify its legitimacy by contacting a known University representative before clicking on any links or downloading attachments.

3. Use Strong, Unique Passwords: If you are concerned about potential account compromises, update your passwords and use two-factor authentication where available.

4. Stay Vigilant for Fraudulent Activity: Keep an eye on your bank accounts, credit reports, and other sensitive accounts for any signs of unauthorized activity.

5. Report Suspicious Activity: If you detect any unusual or unauthorized activity related to your personal information, report it to the University’s help desk, your financial institution, and the appropriate authorities.

These steps will help protect your personal information from misuse.
