ForGeOSI is a wrapper for pyvbox, designed to be used in the education in computer forensics. It simplifies the creation of virtual machines and their automation, while providing a log and reasonable abstraction. The automation of guest systems supports modern Windows Versions with Powershell 2 or newer, while any modern Linux system should be supported in theory, only Ubuntu 12.04 and Ubuntu 13.10 are tested though.

##Requirements As host, a Linux system with VirtualBox 4.3 and the VirtualBox API is expected, Python 2.7 is required, while my software in theory should support Python 3 as well, vboxapi has some hiccups, so it is not advised. Further more, the following Python packets are required:

• pyvbox
• decorator
• enum34
• lxml

The Guest systems should be prepared with Guest Additions installed, further hints are given in the docstring documentation, standalone documentation can be generated with pydoc forgeosi.py

##Installation you can either clone this repository, or install it using pip install forgeosi.

##First Steps Lets start a virtual machine, without cloning it

>ipython
In [1]: import forgeosi

In [2]: print forgeosi.VboxInfo().list_vms()
ubuntu-lts-base
xubuntu-lts-base
windows-8-base

In [3]: vbox = forgeosi.Vbox(mode=forgeosi.VboxMode.use, basename='ubuntu-lts-base')

In [4]: vbox.start(session_type=forgeosi.SessionType.gui)

In [5]: vbox.stop()

Generate input, open webbrowser, send keyboard shortcut, get log

In [1]: import forgeosi

In [2]: vbox = forgeosi.Vbox(mode=forgeosi.VboxMode.use, basename='ubuntu-lts-base')

In [3]: vbox.start(session_type=forgeosi.SessionType.gui)
#top secret password
In [4]: vbox.keyboard_input('12345\n')
#needed to access os-specific and Guest Additions functionality
In [5]: vbox.create_guest_session()

In [6]: vbox.os.open_browser('github.com')

In [7]: vbox.keyboard_combination(['alt','f4'])

In [8]: vbox.stop()

In [9]: print vbox.log.get_pretty_log()

Export virtual machine

In [1]: import forgeosi

In [2]: vbox = forgeosi.Vbox(mode=forgeosi.VboxMode.us, basename='ubuntu-lts-base')

In [3]: vbox.export(path='/tmp/image.vdi')

##Hacking The basic architecture:

• forgeosi.py
  • VboxInfo Helper to get info about the VirtualBox instance
  • VboxConfig Helper to configure the NAT Network feature
  • Vbox Main class containing everything generic to manage virtual machines
• lib/logger.py Logger to provide a protocol of all actions
• lib/oslinux.py Linux guest specific code
• lib/oswindow.py Windows guest specific code
• lib/param.py Types for typesave parameters

Feel free to extend, I will accept pull requests on a reasonable base, especially additions to support a wider range of guest systems are welcome.

##Testing There are testcases to be found test/, but they are not portable and will need fixing to run on other systems. The tests further depend of following tools:

• bash
• Python 3
• The Sleuth Kit ver 4.1 or higher, including fiwalk
• idifference

###Issues Please report issues on github

###Documentation Documentation can be found in docs/ after building with doxygen doxygen.conf or accessed here. Additionaly, you can find my presentation here.

###Known bugs and limitations

• Python 3 compatibility needs to be tested
• raw-disk-export in the python API is broken, I'm using vboxmanage instead
• Running programs in Windows guests with '-' in arguments, breaks things, be careful with that.
• limited support for Windows hosts
