Belgrade School District: Belgrade schools hit by malware, data breach under investigation

Belgrade School District Hit by Malware Attack, Investigates Potential Data Breach

The Belgrade School District in Montana confirmed a malware infection in its network systems, triggering an ongoing investigation into whether student and staff personal data was compromised. The attack was detected when malware infiltrated certain systems, prompting district leaders to isolate affected areas and begin remediation efforts.

Cybersecurity experts are assisting the district in determining the scope of the breach, including whether data beyond the Infinite Campus student information system such as personal details of students and staff was accessed. While the known malware has been removed, recovery efforts are expected to continue into June as crews work to restore affected systems.

The district has stated that individuals whose personal information was exposed will be directly notified, along with guidance on protective measures. Insurance coverage is being used to fund repairs, with reimbursement sought from the district’s insurer. Funds are being allocated not only to restore systems but also to strengthen network defenses against future attacks.

District officials acknowledged the incident has raised concerns among families and staff, emphasizing that protecting private information remains a priority. A full review of all systems is underway before final conclusions are drawn, with updates promised as the investigation progresses. The incident was first reported by local media and verified for accuracy by the outlet’s editorial team.
