\"R\u00e9sultat<\/figure>\n\n\n\n

Un \u00e9norme bug pouvait permettre\u00a0d’\u00e9couter la personne appel\u00e9e avant qu’elle ne d\u00e9croche avec Google Duo, Signal, FaceTime ou encore Facebook Messenger. Il a perdur\u00e9 jusqu’\u00e0 la fin 2020 pour certaines applications.<\/strong><\/p>\n\n\n\n

Signal a le\u00a0vent\u00a0en poupe depuis que\u00a0WhatsApp\u00a0a d\u00e9cid\u00e9 de modifier ses conditions d’utilisation pour partager ses donn\u00e9es avec la maison m\u00e8re Facebook. Ultras\u00e9curis\u00e9e et r\u00e9put\u00e9e pour ne pas collecter de donn\u00e9es personnelles, la\u00a0messagerie, pr\u00f4n\u00e9e par Edward Snowden, a pourtant rencontr\u00e9 une faille cons\u00e9quente jusqu’\u00e0 la fin 2019.<\/p>\n\n\n\n

Lors d’un appel, alors que le correspondant n’a pas encore d\u00e9croch\u00e9, les\u00a0applications\u00a0Signal sur les deux mobiles \u00e9changent des donn\u00e9es pour assurer la connexion. Et il se trouve que, durant cette phase, les \u00e9changes n’\u00e9taient pas limit\u00e9s aux cl\u00e9s de chiffrement et au\u00a0codec. L’appel activait \u00e9galement le microphone du mobile de l’appel\u00e9, ce qui pouvait permettre de l’espionner. D\u00e9tect\u00e9e par la chercheuse en s\u00e9curit\u00e9 Natalie Silvanovich de\u00a0Project Zero, chez Google, cette faille ne concernait\u00a0pas uniquement Signal, mais presque toutes les applications de communication les plus populaires, telles que Facebook\u00a0Messenger, FaceTime, Google Duo, ou encore JioChat qui est tr\u00e8s utilis\u00e9 en Inde.<\/p>\n\n\n\n

Un gros bug corrig\u00e9<\/h2>\n\n\n\n

Si Apple et Signal ont \u00e9t\u00e9 les premiers \u00e0 corriger la faille d\u00e8s 2019, la plupart des\u00a0autres\u00a0messageries\u00a0n’ont pas pris de mesures avant la fin 2020 pour la combler. La chercheuse consid\u00e8re encore plus probl\u00e9matique le cas de\u00a0Google Duo\u00a0car, durant cet \u00e9change initial, des paquets vid\u00e9o pouvaient \u00eatre transmis en plus du son. En revanche, ce\u00a0bug, pourtant commun, ne concerne ni\u00a0Telegram\u00a0ou Viber.<\/p>\n\n\n\n

Dans des explications publi\u00e9es sur son compte\u00a0Twitter, l’experte pr\u00e9cise qu’elle s’est concentr\u00e9e sur les applications qui repr\u00e9sentaient plus de 10 millions d’installations \u00e0 partir du Google Play. Cela signifie que d’autres applications de communication moins populaires pourraient toujours souffrir du m\u00eame bug. Dans tous les cas, mieux vaut v\u00e9rifier que ce type d’application est bien \u00e0 jour sur son t\u00e9l\u00e9phone.<\/p>\n\n\n\n
