开源软件介绍(OpenSource Introduction):

Description

Scrounger - a person who borrows from or lives off others.

There is no better description for this tool for two main reasons, the first is because this tool takes inspiration from many other tools that have already been published, the second reason is because it lives off mobile application's vulnerabilities.

asciicast

Why

Even though several other mobile application analysis tools have been developed, there is no one tool that can be used for both android and ios and can be called a "standard" must use on every mobile application assessment.

The idea behind Scrounger is to make a metasploit-like tool that will not do a pentesters work but help the pentester on his assessment by executing mundane tasks that need to be performed on all assessments.

The Difference

The main features Scrounger offers that others don't:

  • Works with Android and iOS
  • Metasploit-like console and modules
  • Offers a variaty of modules that can be run to give the pentester a starting point
  • Easily extendable

Inspiration / Thanks

Scrounger was inspired by other tools, a huge thanks to the developers of:

Technical

As a disclaimer, all identified findings by Scrounger should always be manually double checked.

When using modules that need an Android or iOS device, Scrounger needs a Rooted or Jailbroken device respectively.

Scrounger has been tested to work on iOS 11 and Android 8.1.

Scrounger has been built for python 2.7 only.

Adding Custom Modules

When installing the application a folder ~/.scrounger will be created. Inside ~/.scrounger will be a folder called modules/custom with the same structure as the default scrounger modules, e.g., analysis/android/module_name.

To create a new custom module just add a new file with the module name you want and it will be included the next time you launch scrounger.

Example

Added the following module (~/.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."
        }
