Une \u00e9quipe de chercheurs a d\u00e9couvert une faille de s\u00e9curit\u00e9 dans l'OS mobile de Google qui affecte les smartphones tournant sur 4.4 KitKat et sup\u00e9rieur, laissant potentiellement 82% des utilisateurs d'Android vuln\u00e9rables<\/strong>.<\/p>\n
Il y a les “certificats parents” et les “certificats enfants”, qui sont v\u00e9rifi\u00e9s l'un face \u00e0 l'autre pendant l'installation pour s'assurer qu'ils concordent et que l'app est fiable. Le certificat parent, g\u00e9n\u00e9ralement transmis par le cr\u00e9ateur de l'app, doit prouver que l'enfant est digne de confiance.<\/p><\/blockquote>\n
Alors que cela devrait en th\u00e9orie fournir un bon niveau de s\u00e9curit\u00e9, Bluebox Labs affirme que non, puisqu'Android ne fait pas assez de v\u00e9rifications sur ces certificats. Cela signifie qu'un entit\u00e9 peut se pr\u00e9senter comme \u00e9tant issue d'un autre entit\u00e9, alors que \u00e7a n'est pas le cas<\/strong>.<\/span><\/p>\n
La cons\u00e9quence est que n'importe quelle app peut contenir un certificat qui se pr\u00e9sente comme \u00e9tant transmis par une source de confiance pour abuser des privil\u00e8ges des parents. Ainsi le certificat Android relatif au NFC pourrait par exemple \u00eatre tromp\u00e9 pour acc\u00e9der au Google Wallet et l\u00e0<\/strong>, la faille prend un enjeu financier direct.<\/p>\n
Bluebox Labs d\u00e9clare que la faille Fake ID est pr\u00e9sente dans Android depuis la version 2,1 jusqu'\u00e0 la 4,4, ce qui concerne donc 82,1% des utilisateurs. Un patch a depuis \u00e9t\u00e9 produit par Google aupr\u00e8s des partenaires Android<\/strong> et sur l'Android Open Source Project, mais cela pourrait prendre du temps avant que cela se fasse un chemin jusqu'\u00e0 votre t\u00e9l\u00e9phone. Au del\u00e0 de \u00e7a, n'oubliez pas les bons gestes pour vous prot\u00e9ger des virus<\/a>.<\/p>\n
