Se han visto comprometidas las claves GPG del proyecto","gt_translate_keys":[{"key":"rendered","format":"text"}]},"content":{"rendered":"

Se han publicado nuevos detalles sobre la violaci\u00f3n de la infraestructura de la plataforma de mensajer\u00eda descentralizada Matrix, de la que se inform\u00f3 esta ma\u00f1ana. El eslab\u00f3n problem\u00e1tico que permit\u00eda la entrada de los atacantes fue el sistema de integraci\u00f3n continua Jenkins, que fue comprometido el 13 de marzo. Luego, en el servidor de Jenkins, se intercept\u00f3 la entrada de uno de los administradores a trav\u00e9s de un agente SSH, y el 4 de abril los atacantes obtuvieron acceso a otros servidores de la infraestructura.<\/p>\n

En el segundo ataque, el sitio matrix.org fue redirigido a otro servidor (matrixnotorg.github.io) mediante el cambio de par\u00e1metros DNS, utilizando la clave de API del sistema de entrega de contenido Cloudflare, que hab\u00eda sido interceptada en el primer ataque. Al reconstruir el contenido servidores<\/a> despu\u00e9s del primer ataque, los administradores de Matrix solo actualizaron las nuevas claves personales y pasaron por alto la actualizaci\u00f3n de la clave de Cloudflare. <\/p>\n

Durante el segundo ataque, los servidores de Matrix permanecieron intactos, y los cambios se limitaron solo a la sustituci\u00f3n de direcciones en DNS. Si un usuario ya ha cambiado su contrase\u00f1a despu\u00e9s del primer ataque, no es necesario que lo haga de nuevo. Pero si la contrase\u00f1a a\u00fan no se ha cambiado, debe actualizarse lo antes posible, ya que se ha confirmado la filtraci\u00f3n de la base de datos con los hashes de contrase\u00f1as. En este momento, se planea iniciar el proceso de restablecimiento forzado de la contrase\u00f1a en el pr\u00f3ximo inicio de sesi\u00f3n.<\/p>\n

Adem\u00e1s de la filtraci\u00f3n de contrase\u00f1as, se ha confirmado que los atacantes tambi\u00e9n obtuvieron las claves GPG utilizadas para formar firmas digitales de paquetes en el repositorio Debian de Synapse y en las versiones de Riot\/Web. Las claves estaban protegidas por contrase\u00f1a. Actualmente, las claves ya han sido revocadas. Las claves fueron interceptadas el 4 de abril, pero desde entonces no se han publicado actualizaciones de Synapse, aunque hubo un lanzamiento del cliente Riot\/Web 1.0.7 (la verificaci\u00f3n preliminar mostr\u00f3 que no fue comprometido). <\/p>\n

El atacante public\u00f3 una serie de informes con detalles del ataque en GitHub, pero fueron eliminados. Sin embargo, los informes se han conservado en el archivo.
