City of Montmagne

The City of Montmagne, also known as Ville de Montmagny, is a municipal government organisation headquartered in Canada. As a city administration, its core function involves providing essential public services and governance to its residents within its jurisdiction. This encompasses typical municipal responsibilities such as local infrastructure management, public safety coordination, permitting, taxation, and community programs necessary for the functioning of an urban area. Its operational scope is geographically defined by the city limits of Montmagne, serving the local population and businesses within that area.

This organisation experienced a significant cybersecurity incident on January 16, 2021. A ransomware attack targeted its digital infrastructure, resulting in a complete shutdown of both computer systems and telephone services. The disruption caused severe operational paralysis across municipal functions reliant on these systems. Telephone services were successfully restored after a period of six days, allowing some communication channels to reopen. However, access to most critical computer systems remained blocked for an extended duration beyond the phone restoration. This prolonged outage severely hampered the city's ability to conduct normal administrative and service delivery operations. The incident underscores the vulnerability of municipal entities to cyber threats capable of halting core governmental activities.
