关于RDPY

RDPY是一款功能强大的RDP远程桌面协议实现工具,该工具基于纯Python开发,并提供了完整的客户端和服务器端应用程序。

RDPY基于事件驱动的网络引擎Twisted构建,RDPY支持标准RDP安全层、RDP over SSL和NLA认证(通过ntlmv2认证协议)。

RDPY提供了下列RDP和VNC代码:

1、RDP中间人代理(用于记录会话);

2、RDP蜜罐;

3、RDP截图工具;

4、RDP客户端;

5、VNC客户端;

6、VNC截图工具;

7、RSS Player;

工具下载

由于该工具基于Python开发,因此我们首先需要在本地设备上安装并配置好Python环境。

接下来,广大研究人员可以使用下列命令将该项目源码克隆至本地:

git clone https://github.com/citronneur/rdpy.git

需要注意的是,该工具所实现的bitmap解压缩算法考虑到性能问题,所以使用了C代码实现。

代码构建

该工具所使用的pyqt4需要用到下列依赖组件:

rdpy-rdpclient

rdpy-rdpscreenshot

rdpy-vncclient

rdpy-vncscreenshot

rdpy-rssplayer

Linux:

sudo apt-get install python-qt4

macOS:

$ brew install qt sip pyqt

Windows:

x86

x86_64

PyQt4

PyQt4

PyWin32

PyWin32

构建命令如下:

$ git clone https://github.com/citronneur/rdpy.git rdpy

$ pip install twisted pyopenssl qt4reactor service_identity rsa pyasn1

$ python rdpy/setup.py install

或使用pip命令构建:

$ pip install rdpy

如需使用Virtualenv,你还需要链接qt4库:

$ 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/

工具使用

RDPY提供了一些非常有用的代码库,这些代码库适用于Linux和Windows操作系统。

rdpy-rdpclient

rdpy-rdpclient是一个简单的RDP Qt4客户端:

$ rdpy-rdpclient.py [-u username] [-p password] [-d domain] [-r rss_ouput_file] [...] XXX.XXX.XXX.XXX[:3389]

rdpy-vncclient

rdpy-vncclient是一个VNC Qt4客户端:

$ rdpy-vncclient.py [-p password] XXX.XXX.XXX.XXX[:5900]

rdpy-rdpscreenshot

rdpy-rdpscreenshot可以将登录屏幕截图保存到文件中:

$ rdpy-rdpscreenshot.py [-w width] [-l height] [-o output_file_path] XXX.XXX.XXX.XXX[:3389]

rdpy-vncscreenshot

rdpy-vncscreenshot可以将第一个界面保存到文件中:

$ rdpy-vncscreenshot.py [-p password] [-o output_file_path] XXX.XXX.XXX.XXX[:5900]

rdpy-rdpmitm

rdpy-rdpmitm是一个RDP代理,允许我们针对RDP协议执行中间人攻击:

$ 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]

rdpy-rdphoneypot

rdpy-rdphoneypot是一个RDP蜜罐,可以在记录会话场景(RSS)中通过RDP协议重放攻击场景:

$ rdpy-rdphoneypot.py [-l listen_port] [-k private_key_file_path] [-c certificate_file_path] rss_file_path_1 ... rss_file_path_N

rdpy-rssplayer

rdpy-rssplayer用于重放rdpy-rdpmitm或rdpy-rdpclient生成的RSS文件:

$ rdpy-rssplayer.py rss_file_path

独立RDPY库

我们还可以将该项目以一个独立协议代码库(+网络引擎Twisted)来使用。
