Russian cyberattack shuts down ETSB network, chair explains response

In this segment of The Pulse of the Eastern Townships, journalist William Crooks speaks with Eastern Townships School Board (ETSB) chair Michael Murray about a cyberattack that disrupted the board’s computer network on Dec. 18, 2025.

The attack prompted ETSB officials to shut down the entire network as a precautionary measure after unauthorized access was detected. During the interview, Murray explains how the intrusion was identified, why the decision was made to take systems offline so quickly, and how the board worked in coordination with Quebec’s Centre gouvernemental de cyberdéfense (COCD) to contain the situation and assess potential impacts.

Murray details which systems were affected and which were not, confirming that sensitive databases — including student identity information, payroll systems and human resources files — were not breached. He also explains why certain devices, such as student Chromebooks and Apple computers used by teachers and senior administrators, were not vulnerable, while PC-based administrative computers required extended shutdown and inspection.

The discussion also addresses the broader context of cyberattacks targeting public institutions, including why school boards are attractive targets for cybercriminals and how personal data can be exploited on illegal online markets. Murray confirms that the attack was traced to a Russian source, while emphasizing that the apparent motivation was financial rather than political.

Finally, the segment outlines the practical impact on schools, staff and families, the anticipated timeline for system cleanup, and the limitations of cyber prevention despite layered security measures.

The interview provides listeners with a detailed, transparent explanation of how the ETSB responded to the incident and what steps are being taken to restore services safely.
