Une faille de s\u00e9curit\u00e9 Android permet \u00e0 des pirates de vous espionner gr\u00e2ce \u00e0 des accessoires Bluetooth et USB, comme des \u00e9couteurs, des casques audio, des\u00a0enceintes, des montres ou des bornes de recharge. D'apr\u00e8s les chercheurs de l'universit\u00e9 de Purdue et de l'Iowa, cette\u00a0importante\u00a0br\u00e8che laisse un attaquant \u00e9couter vos conversations t\u00e9l\u00e9phoniques et collecter vos SMS \u00e0 votre insu.\u00a0<\/strong><\/p>\n

\"android<\/p>\n

Selon l'\u00e9tude relay\u00e9e par nos confr\u00e8res de TechCrunch, 10 smartphones Android populaires, dont le\u00a0Pixel 2<\/a>, le Nexus 6P<\/a> et les Samsung Galaxy S8+<\/a>, Galaxy Note 2 et Galaxy S3<\/a>, peuvent \u00eatre pirat\u00e9s en exploitant une grave faille de s\u00e9curit\u00e9 du\u00a0micrologiciel de la bande de base<\/strong>.<\/p>\n

Certains smartphones Android permettent en effet aux accessoires Bluetooth et USB, tels que des \u00e9couteurs, de communiquer avec la bande de base, la puce qui g\u00e8re toute la partie t\u00e9l\u00e9phonie d'un smartphone. Le dispositif permet au\u00a0modem du t\u00e9l\u00e9phone de communiquer avec le r\u00e9seau cellulaire pour passer des appels, envoyer des SMS ou se connecter \u00e0 internet.\u00a0Normalement, ce micrologiciel n'est pas accessible \u00e0 des accessoires connect\u00e9s \u00e0 votre smartphone.<\/p>\n

Afin de prouver l'existence de la faille, les chercheurs ont mis une point une application de piratage destin\u00e9e \u00e0 communiquer avec la bande de base : ATFuzzer. Gr\u00e2ce \u00e0 cette application, ils sont parvenus \u00e0 lancer 14 commandes sur une dizaine de smartphones diff\u00e9rents<\/strong>. Il est notamment possible d'\u00e9couter les appels t\u00e9l\u00e9phoniques d'un smartphone, de collecter son num\u00e9ro d'identification IMEI, d'intercepter les SMS \u00e9chang\u00e9s ou de rediriger les appels<\/strong> vers un autre t\u00e9l\u00e9phone.<\/p>\n

Pour exploiter cette faille, les pirates doivent imp\u00e9rativement se trouver \u00e0 proximit\u00e9 de leur victime. “Si votre smartphone est connect\u00e9 \u00e0 un casque ou \u00e0 un autre appareil Bluetooth <\/i>(NDLR : comme une\u00a0montre ou une enceinte connect\u00e9e par exemple), l'attaquant peut d'abord exploiter une faille de la connexion Bluetooth avant de lancer des commandes malveillantes”<\/i> mettent en garde les chercheurs. Il est aussi possible d'acc\u00e9der \u00e0 la bande de base via une appareil branch\u00e9 en USB \u00e0 votre t\u00e9l\u00e9phone, comme un ordinateur ou une borne de recharge, pr\u00e9cise l'\u00e9tude.<\/p>\n
