An external attacker breached integrated account records, leaking the PII of 180,000 individuals. The exposure of contact details increases the risk of social engineering and credential harvesting attacks. An unauthorized external IP successfully accessed integrated account records over a three-day window before detection. The leaked dataset includes names, phone numbers, and email addresses, providing a rich source for targeted phishing campaigns. While critical identity documents remained secure, the delay in detection suggests vulnerabilities in the university’s real-time monitoring capabilities.
