La compromisi\u00f3n de la cuenta de administrador llev\u00f3 a un corte de casi cuatro horas en el segundo operador de telecomunicaciones m\u00e1s grande de Espa\u00f1a, Orange Espagne, que atiende a 11 millones de suscriptores. Para acceder a la interfaz del registrador RIPE NCC, Orange Espagne utiliz\u00f3 la contrase\u00f1a predecible \"ripeadmin\" y no se activ\u00f3 la autenticaci\u00f3n de dos factores. <\/p>\n

La contrase\u00f1a de RIPE fue interceptada durante el compromiso del sistema de un empleado por un malware y desde septiembre ha estado en bases de datos de contrase\u00f1as comprometidas a la venta en el mercado negro. Es notable que, adem\u00e1s de la cuenta de Orange Espagne, en esas bases hay miles de otras cuentas para conectar a access.ripe.net, que podr\u00edan usarse potencialmente para llevar a cabo ataques similares. <\/p>\n

El incidente pas\u00f3 desapercibido hasta el 2 de enero, cuando alg\u00fan vandalismo accedi\u00f3 a la interfaz web de RIPE NCC y realiz\u00f3 cambios en la configuraci\u00f3n de BGP y RPKI (Resource Public Key Infrastructure), lo que provoc\u00f3 una interrupci\u00f3n de la red que afect\u00f3 a aproximadamente la mitad del tr\u00e1fico del operador de telecomunicaciones durante casi cuatro horas. Las acciones de los atacantes llevaron a que la tecnolog\u00eda RPKI, dise\u00f1ada para proteger los anuncios BGP de falsificaciones, se utilizara para bloquear anuncios leg\u00edtimos. <\/p>\n

El atacante cre\u00f3 varias nuevas entradas RPKI ROA (Route Origin Authorization), entre las cuales hab\u00eda registros que vinculaban bloques grandes de direcciones de Orange Espagne a un sistema aut\u00f3nomo ajeno, lo que llev\u00f3 a que los anuncios BGP correctos del sistema aut\u00f3nomo de este operador fueran bloqueados en los enrutadores de muchos operadores de red troncales. Como resultado, el n\u00famero de rutas BGP vinculadas a Orange Espagne se redujo de 9200 a 7400, y el tr\u00e1fico disminuy\u00f3 casi a la mitad.

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

RPKI (Resource Public Key Infrastructure) se utiliza para la autorizaci\u00f3n de anuncios BGP y permite determinar si un anuncio BGP proviene realmente del propietario de la red o no. Al utilizar RPKI para sistemas aut\u00f3nomos y direcciones IP<\/a> se establece una cadena de confianza desde IANA a los registradores regionales (RIRs), y luego a los proveedores (LIR) y consumidores finales, que permite a terceros verificar que la operaci\u00f3n con el recurso fue realizada por su propietario. Sin la autorizaci\u00f3n, cualquier operador puede anunciar una subred con informaci\u00f3n falsificada sobre la longitud de la ruta e iniciar el tr\u00e1nsito de parte del tr\u00e1fico de otros sistemas que no aplican filtros en los anuncios.
