Les chercheurs en s\u00e9curit\u00e9 de Check Point ont d\u00e9couvert une faille importante dans TikTok, rendant accessibles aux hackers les donn\u00e9es et num\u00e9ros de t\u00e9l\u00e9phones de nombreux utilisateurs. Celle-ci se trouve au niveau du protocole servant \u00e0 synchroniser les contacts avec les profils des membres de l'application. Elle a depuis \u00e9t\u00e9 signal\u00e9e et r\u00e9par\u00e9e par la firme.<\/b><\/p>\n

Bien qu'elle soit l'application la plus t\u00e9l\u00e9charg\u00e9e de 2020<\/a>, TikTok n'est pas exempt de tout d\u00e9faut. L'institut de recherche en cybers\u00e9curit\u00e9 Check Point a en effet r\u00e9v\u00e9l\u00e9 une faille importante du r\u00e9seau social laissant \u00e0 port\u00e9e de main de tout hacker les donn\u00e9es personnelles de millions d'utilisateurs<\/strong>. Les d\u00e9tails des profils ainsi que les num\u00e9ros de t\u00e9l\u00e9phone associ\u00e9s au compte ont ainsi \u00e9t\u00e9 accessibles pendant une dur\u00e9e ind\u00e9termin\u00e9e.<\/strong><\/p>\n

La faille se trouve au niveau de la fonctionnalit\u00e9 “Trouver des amis<\/strong>“, qui propose de synchroniser ses contacts de fa\u00e7on \u00e0 retrouver le profil de ses connaissances. Cette derni\u00e8re repose sur deux requ\u00eates HTTP<\/strong> : une premi\u00e8re pour envoyer le nom des contacts et les num\u00e9ros correspondants \u00e0 TikTok ; et une seconde pour retrouver les profils des utilisateurs associ\u00e9s aux num\u00e9ros et afficher leur pseudo, photo et autres informations.<\/p>\n
