Kit de test d'applications mobiles
Scrounger - une personne qui emprunte ou vit aux dépens des autres.
Il n'y a pas de meilleure description pour cet outil pour deux raisons principales, la première est que cet outil s'inspire de nombreux autres outils déjà publiés, la seconde est qu'il vit des vulnérabilités des applications mobiles.
Bien que plusieurs autres outils d'analyse d'applications mobiles aient été développés, il n'existe pas d'outil unique pouvant être utilisé à la fois pour android et ios et pouvant être considéré comme un outil « standard » à utiliser lors de chaque évaluation d'application mobile.
L'idée derrière Scrounger est de créer un outil à la manière de Metasploit qui ne fera pas le travail du pentester mais l'aidera dans son évaluation en exécutant des tâches répétitives qui doivent être effectuées sur toutes les évaluations.
Les principales fonctionnalités offertes par Scrounger que les autres n'offrent pas :
Scrounger a été inspiré par d'autres outils, un grand merci aux développeurs de :
En guise d'avertissement, toutes les conclusions identifiées par Scrounger doivent toujours être vérifiées manuellement.
Lors de l'utilisation de modules nécessitant un appareil Android ou iOS, Scrounger a besoin d'un appareil Rooté ou Jailbreaké respectivement.
Scrounger a été testé pour fonctionner sur iOS 11 et Android 8.1.
Scrounger a été développé uniquement pour python 2.7.

## Ajout de modules personnalisés
Lors de l'installation de l'application, un dossier `~/.scrounger` sera créé.
À l'intérieur de `~/.scrounger` se trouvera un dossier nommé `modules/custom` avec la même structure que les modules scrounger par défaut, par exemple `analysis/android/module_name`.
Pour créer un nouveau module personnalisé, ajoutez simplement un nouveau fichier avec le nom du module souhaité et il sera inclus la prochaine fois que vous lancerez scrounger.
### Exemple
Ajout du module suivant (`~/.scrounger/modules/custom/misc/test.py`) :```
from scrounger.core.module import BaseModule
class Module(BaseModule):
meta = {
"author": "RDC",
"description": """Just a Test module""",
"certainty": 100
}
options = [
{
"name": "output",
"description": "local output directory",
"required": False,
"default": None
},
]
def run(self):
print("This is a print from the custom module")
return {
"print": "This will be print by scrounger's console."
}
