Migliaccio & Rathod LLP is involved in the Columbia University Data Breach Investigation, regarding a breach that impacted 868,969 individuals and their personal information.
Columbia University (“Columbia“) experienced a technical outage that disrupted certain IT systems on June 24, 2025. After the outage, Columbia claims that it promptly activated its “response process,” initiated an investigation with the assistance of external cybersecurity experts, and reported the incident to law enforcement. Ultimately, Columbia’s investigation uncovered that, on or about May 16, 2025, a hacker accessed its network and stole files containing the personally identifiable information of Columbia students and those who have applied to the Ivy League institution. The compromised information includes the following sensitive data:
- full names
- dates of birth
- phone numbers
- other demographic information
- physical addresses
- Social Security numbers
- academic histories
- financial aid-related information
- health information
- health insurance-related information
The Columbia University Data Breach
Columbia University recently provided notice of the data breach. All of the information stolen is likely valuable and dangerous to affected victims. As is likely to be the case with the Columbia University data breach, in previous cyberattacks, victims of data theft have noticed identity theft attempts ranging from fraudulent charges on bank accounts or credit cards, to unauthorized credit card applications, to medical services or government services ordered in their name, to their information being posted on the dark web, to a massive uptick in the number of spam text messages, calls and emails received.
