Columbia University Notifies Texas AG of Data Security Incident

Columbia University filed an official data breach notification with the Texas Attorney General's office on May 20, 2026. This report states that the university experienced a data security incident that occurred on or around May 16, 2025, potentially involving unauthorized access to its internal systems. The incident is currently under investigation by the university.

While the specific types of data exposed were not detailed in the public filing, the notification indicates that personal information maintained by Columbia University was potentially compromised. The university manages extensive records for students, faculty, staff, and alumni. If you received a direct notification letter from Columbia University, it means your personal data was likely among the affected files.

This type of incident means that individuals whose data was affected should remain vigilant for unusual activity. Unauthorized access to personal information can increase the risk of identity theft or other fraudulent activities. The university's notification aims to alert those potentially impacted so they can take protective measures.

Those who received a notification letter should carefully review it for any specific recommendations from Columbia University. It is generally advisable to monitor account statements and credit reports for any suspicious transactions or new accounts opened in your name.

Consider placing a fraud alert or security freeze on your credit files with the major credit bureaus to help prevent unauthorized access to new credit. Be cautious of unsolicited communications that request personal information, as these could be phishing attempts designed to exploit data from the incident.
