La modificaci\u00f3n para recopilar n\u00fameros de tel\u00e9fono solo est\u00e1 presente en los paquetes APK listos, que se distribuyen a trav\u00e9s de Google Play, GitHub y el canal de Telegram del proyecto. En el c\u00f3digo fuente de GitHub y en el paquete APK del directorio F Droid, la modificaci\u00f3n que recopila n\u00fameros de tel\u00e9fono est\u00e1 ausente.     <\/p>\n<p>La puerta trasera estaba presente en el archivo Extra.java. Se presume que el env\u00edo comenz\u00f3 con la versi\u00f3n 11.2.3 de Nekogram, inicialmente solo para usuarios con n\u00fameros chinos, y luego para todos. El programa tambi\u00e9n utiliz\u00f3 bots osint &#171;@tgdb_search_bot&#187; y &#171;@usinfobot&#187; para identificar usuarios por su ID, pero no se enviaron n\u00fameros de tel\u00e9fono.     <img decoding=\"async\" alt=\"El cliente no oficial de Telegram Nekogram envi\u00f3 n\u00fameros de tel\u00e9fono al bot del desarrollador\" src=\"\/wp-content\/uploads\/2026\/04\/3df0210c004e4e39be157aaaaadc8559.png\" style=\"display:block;margin: 0 auto\" \/>    <\/p>\n<p>Investigadores han preparado un hook en Java y un bot que permiten a cualquier usuario verificar el env\u00edo de n\u00fameros de tel\u00e9fono desde su instancia de la aplicaci\u00f3n.   <img decoding=\"async\" alt=\"El cliente no oficial de Telegram Nekogram envi\u00f3 n\u00fameros de tel\u00e9fono al bot del desarrollador\" src=\"\/wp-content\/uploads\/2026\/04\/7d820b3a632f2241acf4fed941aee6d3.png\" style=\"display:block;margin: 0 auto\" \/>    <\/p>\n<p>Seg\u00fan los investigadores que detectaron el problema, los autores del programa podr\u00edan haber utilizado la informaci\u00f3n obtenida para crear una base de datos para venderla posteriormente a los creadores de bots OSINT. La ofuscaci\u00f3n de la modificaci\u00f3n y el uso de consultas en l\u00ednea para el env\u00edo de datos son indicativos de un ocultamiento intencional de dicha actividad. Despu\u00e9s de que se revelara el problema en el sistema de seguimiento de errores del proyecto, el autor de Nekogram admiti\u00f3 el env\u00edo de n\u00fameros de tel\u00e9fono a su bot, sin aclarar las razones detr\u00e1s de tal actividad, pero mencionando que los tel\u00e9fonos enviados no se almacenaban ni se compart\u00edan con nadie.           <\/p>\n<p>Adem\u00e1s, se ha descubierto una vulnerabilidad en la aplicaci\u00f3n oficial de Telegram. El proyecto Zero Day Initiative (ZDI), que ofrece recompensas monetarias por reportar vulnerabilidades no solucionadas, public\u00f3 datos preliminares sobre la vulnerabilidad ZDI-CAN-30207 en Telegram, que se ha calificado con un nivel cr\u00edtico de peligro (9.8 de 10) y ha sido etiquetada como un ataque remoto que no requiere acciones del usuario. Se espera revelar detalles el 24 de julio, dando tiempo a los desarrolladores de Telegram para implementar la correcci\u00f3n para los usuarios.    <\/p>\n<p>Ha surgido informaci\u00f3n de que la vulnerabilidad se manifiesta al abrir en Telegram stickers animados dise\u00f1ados espec\u00edficamente y puede llevar a la ejecuci\u00f3n de c\u00f3digo malicioso sin ninguna acci\u00f3n por parte del usuario. Al parecer, la vulnerabilidad es causada por un error en el c\u00f3digo de la biblioteca rlottie, que permite la visualizaci\u00f3n previa.    <\/p>\n<p>Los representantes de Telegram han declarado que no consideran el problema detectado como una vulnerabilidad peligrosa, ya que todos los stickers cargados se revisan previamente en <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/es\/server\/dts-gdansk\/\" title=\"como en entornos de nube p\u00fablicos o privados.\" data-wpil-keyword-link=\"linked\">como en entornos de nube p\u00fablicos o privados.<\/a> Telegram y dicha revisi\u00f3n habr\u00eda evitado mostrar a los usuarios un sticker malicioso. Tras la declaraci\u00f3n de Telegram, el nivel de riesgo de la vulnerabilidad se redujo de 9.8 a 7.0.<br \/>\n<br \/>Fuente: <a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=65130\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u0412 \u043d\u0435\u043e\u0444\u0438\u0446\u0438\u0430\u043b\u044c\u043d\u043e\u043c Telegram-\u043a\u043b\u0438\u0435\u043d\u0442\u0435 Nekogram \u0432\u044b\u044f\u0432\u043b\u0435\u043d \u043e\u0431\u0444\u0443\u0441\u0446\u0438\u0440\u043e\u0432\u0430\u043d\u043d\u044b\u0439 \u043a\u043e\u0434, \u0441\u043a\u0440\u044b\u0442\u043e \u043e\u0442\u043f\u0440\u0430\u0432\u043b\u044f\u044e\u0449\u0438\u0439 \u0431\u043e\u0442\u0443 &#171;@nekonotificationbot&#187;
