La compromission du compte administrateur a entra\u00een\u00e9 une interruption de pr\u00e8s de quatre heures des services du deuxi\u00e8me op\u00e9rateur de t\u00e9l\u00e9communications espagnol, Orange Espagne, qui dessert 11 millions d'abonn\u00e9s. Un mot de passe pr\u00e9visible «ripeadmin» a \u00e9t\u00e9 utilis\u00e9 pour acc\u00e9der \u00e0 l'interface du registre RIPE NCC chez Orange Espagne, et l'authentification \u00e0 deux facteurs n'\u00e9tait pas activ\u00e9e. <\/p>\n

Le mot de passe RIPE a \u00e9t\u00e9 intercept\u00e9 lors de l'infection d'un syst\u00e8me d'un employ\u00e9 par un logiciel malveillant et \u00e9tait en vente sur le march\u00e9 noir depuis septembre dans des bases de donn\u00e9es de mots de passe compromis. Il est notable que, en plus du compte d'Orange Espagne, ces bases contiennent des milliers d'autres comptes pour se connecter \u00e0 access.ripe.net, qui pourraient potentiellement \u00eatre utilis\u00e9s pour mener des attaques similaires. <\/p>\n

L'incident est rest\u00e9 inaper\u00e7u jusqu'au 2 janvier, lorsque qu'un vandale a acc\u00e9d\u00e9 \u00e0 l'interface web de RIPE NCC et a modifi\u00e9 les param\u00e8tres BGP et RPKI (Resource Public Key Infrastructure), provoquant ainsi une perturbation de la route d'environ la moiti\u00e9 du trafic de l'op\u00e9rateur pendant pr\u00e8s de quatre heures. Les actions des attaquants ont conduit \u00e0 l'utilisation de la technologie RPKI, con\u00e7ue pour prot\u00e9ger les annonces BGP contre la contrefa\u00e7on, pour bloquer des annonces l\u00e9gitimes. <\/p>\n

L'attaquant a cr\u00e9\u00e9 plusieurs nouveaux enregistrements RPKI ROA (Route Origin Authorization), parmi lesquels figuraient des enregistrements liant de grands blocs d'adresses d'Orange Espagne \u00e0 un syst\u00e8me autonome \u00e9tranger, ce qui a entra\u00een\u00e9 le blocage des annonces BGP correctes de ce syst\u00e8me sur les routeurs de nombreux op\u00e9rateurs de backbone. En fin de compte, le nombre de routes BGP li\u00e9es \u00e0 Orange Espagne est pass\u00e9 de 9200 \u00e0 7400, et le trafic a chut\u00e9 de presque moiti\u00e9.

\"La<\/center> <\/p>\n

RPKI (Resource Public Key Infrastructure) est utilis\u00e9 pour autoriser les annonces BGP et permet de d\u00e9terminer si une annonce BGP provient bien du propri\u00e9taire du r\u00e9seau ou non. Lors de l'utilisation de RPKI pour les syst\u00e8mes autonomes et adresses IP<\/a> \u00e9tablit une cha\u00eene de confiance de l'IANA aux registres r\u00e9gionaux (RIR), puis aux fournisseurs (LIR) et aux utilisateurs finaux, permettant \u00e0 des tiers de v\u00e9rifier qu'une op\u00e9ration sur une ressource a \u00e9t\u00e9 effectu\u00e9e par son propri\u00e9taire. Sans l'utilisation de l'autorisation, n'importe quel op\u00e9rateur peut annoncer un sous-r\u00e9seau avec des informations fictives sur la longueur du chemin et initier le transit d'une partie du trafic d'autres syst\u00e8mes ne filtrant pas les annonces.
