Permisos desconocidos en el análisis de VirusTotal

He notado un comportamiento inusual y no deseado en algunas de las aplicaciones de mi sistema, en particular, Google Play Services, Google Account Manager y Google Services Framework. Estas aplicaciones causan cierres forzados en sus propias operaciones, así como en las de otras aplicaciones, a veces parecen tener la capacidad de hacerse cargo de la funcionalidad de mi teléfono por completo.

Entonces, utilicé la herramienta Virustotal.com para analizar los permisos en estas aplicaciones para determinar si están presentes con las capacidades correctas integradas para la versión que viene preinstalada en el teléfono. Para cada una de estas aplicaciones, devolvieron entre 10 y 20 permisos adicionales cada uno para los que no estaban diseñados, lo que sugiere que han sido manipulados.

Mi teléfono no está rooteado ni modificado de ninguna manera y lo tengo desde hace menos de un año. Estos permisos adicionales fueron etiquetados:

(Permiso desconocido de la referencia de Android)

designando estos permisos específicos como no nativos de estas aplicaciones. Algunos de estos permisos están diseñados específicamente para la transmisión y comunicación de datos a través de C2DM y Gtalk a otros dispositivos, así como para la exposición de detalles de cuentas guardados, incluidas las contraseñas. Esto me lleva a concluir que se ha filtrado información personal sensible a terceros. Aquí está la salida para el Administrador de cuentas de Google como ejemplo:
