The University of Southern California (USC) experienced a data breach reported by the California Office of the Attorney General on June 29, 2012. The incident involved unauthorized access to credit card numbers used at USC dining venues between May 21 and June 21, 2012. While the breach exposed payment card data, no personally identifiable information (PII)—such as names, addresses, or Social Security numbers—was compromised. USC responded by immediately disabling the affected system and collaborating with a third-party vendor to enhance security measures. The breach was contained to financial transaction data, with no evidence of broader data exfiltration or misuse beyond the exposed credit card details. The university emphasized that the incident did not impact academic, administrative, or personal records of students, faculty, or staff. The focus remained on mitigating risks associated with potential fraudulent transactions linked to the compromised payment system.
