Une cyberattaque a paralysé le département francilien des Hauts-de-Seine depuis le matin du mardi 20 mai. L'administration a coupé les moyens de télécommunication par précaution, désactivant temporairement l’ensemble des systèmes d’information et des moyens de communication habituels. Les services numériques et de communication du département tournent au ralenti. L'ampleur de l'attaque est encore inconnue, mais les risques sont significatifs dans ce département très actif et peuplé, abritant le quartier d'affaires de la Défense et plusieurs grandes communes. Toutes les mesures sont mises en œuvre pour évaluer l'impact, protéger les données des agents et des usagers, et rétablir les accès au réseau et aux applications.
