Herramientas para analizar APK (app Android)

APK son las siglas de Android Aplication Package. Este tipo de archivo contiene el programa o aplicación que queremos instalar de la misma manera que también el instalador. Por tanto diremos que se trata de un archivo instalable concebido para Android.

Para analizar una aplicación, lo primero es conseguir el archivo .APK (Android) o .IPA (iOS). Para descargar el .APK de la PlayStore se puede utilizar el servicio de APKPure. Solo se debe pasar la URL oficial de la PlayStore. Esta herramienta no hace ningún cambio a la aplicación descargada por lo que hasta la fecha es un servicio confiable.

Este repositorio GIT tiene un listado actualizado de herramientas para analizar aplicaciones de Android (APK), al igual que Android Arsenal.

Online Tools

  • Mobile Security Framework (MobSF): Es LA herramienta, la que recomiendo abiertamente para el análisis dinámico y estático de apps, independiente de la plataforma (Android o iOS), si vas a realizar el análisis de aplicaciones móviles habitualmente esta herramienta no puede faltar en tu arsenal.
  • Quick Android Review Kit o QARK: Es un framework de análisis automatizado de aplicaciones android que tiene poco tiempo de vida, esta enfocado al análisis de aplicaciones android y cuenta con muy buenas funcionalidades.
  • SandDroid (informe de ejemplo): Es una de las mejores herramientas online que podemos tener para el análisis automático de aplicaciones android, realiza análisis dinámico y estático, además de darnos un puntaje de riesgo basado en la información que logra recolectar.
  • Reverse.it (informe de ejemplo): Es una herramienta que también permite el análisis dinámico y estático de aplicaciones android de forma automatizada, es una especialmente útil cuando buscamos comportamientos anómalos dentro de las aplicaciones móviles.
  • Dexter: Para un análisis más detallado podemos usar (previo registro gratuito) esta herramienta, enfocada en el análisis de software que nos permite de forma colaborativa visualizar el funcionamiento de la aplicación con un potente buscador que nos ayudará a encontrar fácilmente funciones interesantes en las cuales centrar nuestra atención.
  • JavaDecompilers: Es una herramienta online que nos permite decompilar aplicaciones online abriendo la posibilidad de examinar su código fuente desde un simple navegador, si con Dexter encontraste funciones interesantes que analizar, con javadecompilers puedes examinar sus entrañas para ver su funcionamiento a nivel de código.
