Curated summary with source attribution

Threat Risk: Medium
Victim: Higher Education Institution
Incident: An unauthorized actor compromised a staff email account to forward financial communications to an external Gmail address.
Impact: Personal data of 187 individuals was breached and classified as high risk.
Attacker: Unidentified threat actor
Analysis: The attacker gained unauthorized access to a staff email account and established a stealthy forwarding rule to exfiltrate messages containing financial keywords. This incident underscores a common Business Email Compromise (BEC) tactic used for long-term data harvesting. Forensic efforts were significantly hindered by inadequate log retention, preventing the university from pinpointing the exact breach window.
Recommendations: Implement automated alerts for the creation of new email forwarding rules.; Enforce phishing-resistant multi-factor authentication (MFA) across all staff accounts.; Review and extend log retention policies to ensure visibility into historical account activity.
