Baltimore City Schools suffered a computer network breach in February 2024, potentially compromising documents of current, former, and prospective employees, volunteers, contractors, and files linked to less than 1.5% of students (~1,000 out of 75,000). The breach triggered an investigation with law enforcement and external cybersecurity consultants, leading to immediate actions like password resets, endpoint detection software deployment, and a forensic audit. Affected individuals are being notified via mail and offered complimentary credit monitoring, identity-theft mitigation, and dark-web monitoring. The district is establishing a call center for support and continues assessing the scope of compromised data, though specifics remain under review. Operational disruptions were acknowledged, but no evidence of ransomware, financial fraud, or systemic outages was reported. The focus remains on notifying impacted parties and strengthening defenses against future threats.
