Description
On March 13, 2022, the Communauté de Communes de Montesquieu, an intercommunal structure governing 13 municipalities, experienced a cyberattack targeting its servers. The disruption became apparent on Monday, March 14, when staff lost access to email systems and internal files, severely impairing administrative operations. The organization publicly confirmed the incident on Wednesday, March 16, through an official statement, though it did not disclose the specific attack vector or duration of server compromise. The immediate consequence was widespread operational disruption across the community's services, though critical public-facing utilities like water or emergency services were not mentioned as affected. No evidence suggested data exfiltration or ransom demands were reported at this stage.
The intercommunal IT department initiated emergency response procedures immediately upon detecting the disruption. Their efforts focused on restoring server functionality and minimizing service impacts for residents and business partners. The organization engaged France's National Agency for the Security of Information Systems (ANSSI), which provided forensic and incident response guidance. Following ANSSI's protocols, the community filed a formal complaint with the National Gendarmerie to initiate a criminal investigation. Restoration timelines and whether backups were utilized were not disclosed in available reporting. The incident highlighted vulnerabilities in local government infrastructure without specifying whether prior security deficiencies existed.
