RDPY - Remote Desktop Protocol in Twisted Python


RDPY is a pure Python implementation of the Microsoft RDP (Remote Desktop Protocol) protocol (client and server side). RDPY is built over the event driven network engine Twisted. RDPY support standard RDP security layer, RDP over SSL and NLA authentication (through ntlmv2 authentication protocol).

RDPY provides the following RDP and VNC binaries :
  • RDP Man In The Middle proxy which record session
  • RDP Honeypot
  • RDP screenshoter
  • RDP client
  • VNC client
  • VNC screenshoter
  • RSS Player

Build
RDPY is fully implemented in python, except the bitmap decompression algorithm which is implemented in C for performance purposes.

Dependencies
Dependencies are only needed for pyqt4 binaries :
  • rdpy-rdpclient
  • rdpy-rdpscreenshot
  • rdpy-vncclient
  • rdpy-vncscreenshot
  • rdpy-rssplayer

Linux
Example for Debian based systems :
sudo apt-get install python-qt4

OS X
Example for OS X to install PyQt with homebrew
$ brew install qt sip pyqt

Windows
x86 x86_64
PyQt4 PyQt4
PyWin32 PyWin32

Build
$ git clone https://github.com/citronneur/rdpy.git rdpy
$ pip install twisted pyopenssl qt4reactor service_identity rsa pyasn1
$ python rdpy/setup.py install
Or use PIP:
$ pip install rdpy
For virtualenv, you will need to link the qt4 library to it:
$ ln -s /usr/lib/python2.7/dist-packages/PyQt4/ $VIRTUAL_ENV/lib/python2.7/site-packages/
$ ln -s /usr/lib/python2.7/dist-packages/sip.so $VIRTUAL_ENV/lib/python2.7/site-packages/

RDPY Binaries
RDPY comes with some very useful binaries. These binaries are linux and windows compatible.

rdpy-rdpclient
rdpy-rdpclient is a simple RDP Qt4 client.
$ rdpy-rdpclient.py [-u username] [-p password] [-d domain] [-r rss_ouput_file] [...] XXX.XXX.XXX.XXX[:3389]
You can use rdpy-rdpclient in a Recorder Session Scenario, used in rdpy-rdphoneypot.

rdpy-vncclient
rdpy-vncclient is a simple VNC Qt4 client .
$ rdpy-vncclient.py [-p password] XXX.XXX.XXX.XXX[:5900]

rdpy-rdpscreenshot
rdpy-rdpscreenshot saves login screen in file.
$ rdpy-rdpscreenshot.py [-w width] [-l height] [-o output_file_path] XXX.XXX.XXX.XXX[:3389]

rdpy-vncscreenshot
rdpy-vncscreenshot saves the first screen update in file.
$ rdpy-vncscreenshot.py [-p password] [-o output_file_path] XXX.XXX.XXX.XXX[:5900]

rdpy-rdpmitm
rdpy-rdpmitm is a RDP proxy allows you to do a Man In The Middle attack on RDP protocol. Record Session Scenario into rss file which can be replayed by rdpy-rssplayer.
$ rdpy-rdpmitm.py -o output_dir [-l listen_port] [-k private_key_file_path] [-c certificate_file_path] [-r (for XP or server 2003 client)] target_host[:target_port]
Output directory is used to save the rss file with following format (YYYYMMDDHHMMSS_ip_index.rss) The private key file and the certificate file are classic cryptographic files for SSL connections. The RDP protocol can negotiate its own security layer If one of both parameters are omitted, the server use standard RDP as security layer.

rdpy-rdphoneypot
rdpy-rdphoneypot is an RDP honey Pot. Use Recorded Session Scenario to replay scenario through RDP Protocol.
$ rdpy-rdphoneypot.py [-l listen_port] [-k private_key_file_path] [-c certificate_file_path] rss_file_path_1 ... rss_file_path_N
The private key file and the certificate file are classic cryptographic files for SSL connections. The RDP protocol can negotiate its own security layer. If one of both parameters are omitted, the server use standard RDP as security layer. You can specify more than one files to match more common screen size.

rdpy-rssplayer
rdpy-rssplayer is use to replay Record Session Scenario (rss) files generates by either rdpy-rdpmitm or rdpy-rdpclient binaries.
$ rdpy-rssplayer.py rss_file_path

RDPY Qt Widget
RDPY can also be used as Qt widget through rdpy.ui.qt4.QRemoteDesktop class. It can be embedded in your own Qt application. qt4reactor must be used in your app for Twisted and Qt to work together. For more details, see sources of rdpy-rdpclient.

RDPY library
In a nutshell RDPY can be used as a protocol library with a twisted engine.
