Le registre APNIC, responsable de la r\u00e9partition des adresses IP dans la r\u00e9gion Asie-Pacifique, a annonc\u00e9 un incident o\u00f9 un dump SQL du service Whois, contenant des donn\u00e9es sensibles et des hachages de mots de passe, a \u00e9t\u00e9 rendu public. Il est notable que ce n'est pas la premi\u00e8re fuite de donn\u00e9es personnelles chez APNIC : en 2017, la base de donn\u00e9es Whois avait \u00e9galement \u00e9t\u00e9 expos\u00e9e par n\u00e9gligence du personnel. <\/p>\n

Lors de l'impl\u00e9mentation du support du protocole RDAP, destin\u00e9 \u00e0 remplacer le protocole WHOIS, les employ\u00e9s d'APNIC ont plac\u00e9 un dump SQL de la base utilis\u00e9e dans le service Whois dans un stockage cloud Google Cloud, mais n'ont pas restreint l'acc\u00e8s. En raison d'une erreur de configuration, le dump SQL est rest\u00e9 accessible publiquement pendant trois mois, et ce fait n'a \u00e9t\u00e9 d\u00e9couvert que le 4 juin, lorsqu'un chercheur en s\u00e9curit\u00e9 ind\u00e9pendant a attir\u00e9 l'attention sur ce probl\u00e8me et a inform\u00e9 le registraire. <\/p>\n

Le dump SQL contenait des attributs \u00ab auth \u00bb, incluant des hachages de mots de passe pour modifier les objets Maintainer et Incident Response Team (IRT), ainsi que certaines informations confidentielles sur les clients qui ne sont pas affich\u00e9es dans Whois lors de requ\u00eates ordinaires (g\u00e9n\u00e9ralement des coordonn\u00e9es suppl\u00e9mentaires et des notes sur l'utilisateur). En cas de r\u00e9cup\u00e9ration des mots de passe, les attaquants auraient pu modifier le contenu des champs avec les param\u00e8tres des propri\u00e9taires des blocs adresses IP<\/a> dans Whois. L'objet Maintainer d\u00e9finit la personne responsable de la modification du groupe d'enregistrements li\u00e9s par l'attribut \u00ab mnt-by \u00bb, tandis que l'objet IRT contient les coordonn\u00e9es des administrateurs r\u00e9pondant aux notifications de probl\u00e8mes. Les d\u00e9tails concernant l'algorithme de hachage des mots de passe ne sont pas fournis, mais en 2017, des algorithmes obsol\u00e8tes tels que MD5 et CRYPT-PW (mots de passe de 8 caract\u00e8res hach\u00e9s sur la base de la fonction UNIX crypt) \u00e9taient utilis\u00e9s. <\/p>\n

Apr\u00e8s la d\u00e9couverte de l'incident, APNIC a initi\u00e9 une r\u00e9initialisation des mots de passe pour les objets dans Whois. Du c\u00f4t\u00e9 d'APNIC, aucun signe d'actions ill\u00e9gitimes n'a encore \u00e9t\u00e9 d\u00e9tect\u00e9, mais il n'y a aucune garantie que les donn\u00e9es n'aient pas \u00e9t\u00e9 compromises, puisque les logs d'acc\u00e8s complets aux fichiers dans Google Cloud sont absents. Comme apr\u00e8s le pr\u00e9c\u00e9dent incident, APNIC a promis de proc\u00e9der \u00e0 un audit et d'apporter des modifications aux processus technologiques pour \u00e9viter de telles fuites \u00e0 l'avenir.
