MultiScanner - Modular File Scanning/Analysis Framework



Friday, April 21, 2017


MultiScanner is a file analysis framework that assists the user in evaluating a set of files by automatically running a suite of tools for the user and aggregating the output. Tools can be custom built python scripts, web APIs, software running on another machine, etc. Tools are incorporated by creating modules that run in the MultiScanner framework.
Modules are designed to be quickly written and easily incorporated into the framework. Currently written and maintained modules are related to malware analytics, but the framework is not limited to that scope. For a list of modules you can look in modules, descriptions and config options can be found in docs/modules.md

Requirements
Python 2.7 is recommended. Compatibility with 2.7+ and 3.3+ is supported but not thoroughly maintained and tested. Please submit an issue or a pull request fixing any issues found with other versions of Python.
An installer script is included in the project install.sh, which installs the prerequisites on most systems.

Installation

MultiScanner
If you're running on a RedHat or Debian based linux distribution you should try and run install.sh. Otherwise the required python packages are defined in requirements.txt.
MultiScanner must have a configuration file to run. Generate the MultiScanner default configuration by running python multiscanner.py init after cloning the repository. This command can be used to rewrite the configuration file to its default state or, if new modules have been written, to add their configuration to the configuration file.

Analytic Machine
Default modules have the option to be run locally or via SSH. The development team runs MultiScanner on a Linux host and hosts the majority of analytical tools on a separate Windows machine. The SSH server used in this environment is freeSSHd from http://www.freesshd.com/.
A network share accessible to both the MultiScanner and the Analytic Machines is required for the multi-machine setup. Once configured, the network share path must be identified in the configuration file, config.ini. To do this, set the copyfilesto option under [main] to be the mount point on the system running MultiScanner. Modules can have a replacement path option, which is the network share mount point on the analytic machine.

Module Writing
Modules are intended to be quickly written and incorporated into the framework. A finished module must be placed in the modules folder before it can be used. The configuration file does not need to be manually updated. See docs/module_writing.md for more information.

Module Configuration
Modules are configured within the configuration file, config.ini. See docs/modules.md for more information.

Python API
MultiScanner can be incorporated as a module in another projects. Below is a simple example of how to import MultiScanner into a Python script.
import multiscanner
output = multiscanner.multiscan(FileList)
Results = multiscanner.parse_reports(output, python=True)
Results is a dictionary object where each key is a filename of a scanned file.
multiscanner.config_init(filepath) will create a default configuration file at the location defined by filepath.
