Gonzaga Preparatory School

The Washington State Office of the Attorney General disclosed a ransomware attack targeting Gonzaga Preparatory School, occurring between February 7, 2020, and May 20, 2020, and reported on August 17, 2020. The incident compromised the personal data of 5,000 Washington residents, including names and dates of birth. While the attack involved ransomware, there was no explicit confirmation of data exfiltration beyond the exposure of sensitive personal identifiers. The breach highlights vulnerabilities in the school’s cybersecurity infrastructure, raising concerns over potential identity theft or fraud risks for affected individuals. The attack did not explicitly mention financial losses, operational disruptions, or broader systemic consequences beyond the exposure of personal information. Authorities likely initiated notifications to impacted parties, though the long detection window (over three months) underscores challenges in timely incident response.
