Scrying - A Tool For Collecting RDP, Web And VNC Screenshots All In One Place


A new tool for collecting RDP, web and VNC screenshots all in one place

This tool is still a work-in-progress and should be mostly usable but is not yet complete. Please file any bugs or feature requests as GitHub issues


Caveats
  • Web screenshotting relies on Chromium or Google Chrome being installed

Motivation

Since Eyewitness recently dropped support for RDP there isn't a working CLI tool for capturing RDP screenshots. Nessus still works, but it's a pain to get the images out and they're not included in the export file.

I thought this was a good opportunity to write a fresh tool that's more powerful than those that came before. Check out the feature list!


Installation

For web screenshotting, scrying currently depends on there being an installation of Chromium or Google Chrome. Install with pacman -S chromium or the equivalent for your OS.

Download the latest release from the releases tab. There's a Debian package available for distros that use them (install with sudo dpkg -i scrying*.deb), and zipped binaries for Windows, Mac, and other Linuxes.


Usage

Grab a single web page, RDP server, or VNC server:

$ scrying -t http://example.com
$ scrying -t rdp://192.0.2.1
$ scrying -t 2001:db8::5 --mode web
$ scrying -t 2001:db8::5 --mode rdp
$ scrying -t 192.0.2.2
$ scrying -t vnc://[2001:db8::53]:5901

Automatically grab screenshots from an nmap output:

$ nmap -iL targets.txt -p 80,443,8080,8443,3389 -oX targets.xml
$ scrying --nmap targets.xml

Choose a different output directory for images:

$ scrying -t 2001:db8::3 --output-dir /tmp/scrying_outputs

Run from a targets file:

$ cat targets.txt
http://example.com
rdp://192.0.2.1
2001:db8::5
$ scrying -f targets.txt

Run through a web proxy:

$ scrying -t http://example.com --web-proxy http://127.0.0.1:8080
$ scrying -t http://example.com --web-proxy socks5://\[::1\]:1080

Image files are saved as PNG in the following directory structure:

output
├── report.html
├── rdp
│   └── 192.0.2.1-3389.png
├── vnc
│   └── 192.0.2.1-5900.png
└── web
└── https_example.com.png

Features:

Features with ticks next to them have been implemented, others are TODO

  • ✔️ Automatically decide whether an input should be treated as a web address or RDP server
  • ✔️ Automatically create output directory if it does not already exist
  • ✔️ Save images with consistent and unique filenames derived from the host/IP
  • ✔️ Full support for IPv6 and IPv4 literals as well as hostnames
  • ✔️ Read targets from a file and decide whether they're RDP or HTTP or use hints
  • ✔️ Parse targets smartly from Nmap and Nessus output
  • ✔️ HTTP - uses Chromium/Chrome in headless mode
  • ✔️ Full cross-platform support - tested on Linux, Windows and Mac
  • Produces an HTML report to allow easy browsing of the results
  • VNC
  • RDP - mostly working, does not support "plain RDP" mode, see #15
  • Video streams - tracking issue #5
  • option for timestamps in filenames
  • Read targets from a msf services -o csv output
  • OCR on RDP usernames, either live or on a directory of images
  • NLA/auth to test credentials
  • Parse Dirble JSON output to grab screenshots of an entire website - waiting for nccgroup/dirble#51
