Scrying: RDP, Web and VNC screenshot capture tool

Scrying is a new tool for capturing RDP, Web and VNC screenshots. This tool is still a work in progress and can be used but it is not complete.

RDP, Web and VNC are services Remote Desktop help control the computer remotely, if the account is exposed, it is considered that the Hacker has full rights to use your computer.

The web screenshot feature is based on whether Chromium or Google Chrome is installed.

Since Eyewitness has recently stopped supporting RDP, there are no CLI tools that take RDP screenshots. Nessus still works, but it’s a bit difficult to get the image out and it can’t export the file.

So this is a good opportunity for the author to write a new tool that is more powerful than the previous ones.

Install Crying

For the web screenshot feature, the tool has to depend on whether you have Chromium or Google Chrome installed.

Download the latest release at github. Debian versions are available for the distributions to use (install using the sudo dpkg -i scrying* .deb) and binaries for Windows, Mac, and Linux.

Use

Find a website, RDP server or VNC server:

$ scrying -t http:

$ scrying -t rdp:

$ scrying -t 2001:db8::5 --mode web

$ scrying -t 2001:db8::5 --mode rdp

$ scrying -t 192.0.2.2

$ scrying -t vnc:

Crying will automatically get the screenshot from the nmap output:

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

$ scrying --nmap targets.xml

Choose a different output folder for the images:

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

Run the targets file:

$ cat targets.txt

http:

rdp:

2001:db8::5

$ scrying -f targets.txt


Run using web proxy:

$ scrying -t http:

$ scrying -t http:

The image file will be saved as PNG in the following folder structure:

Check the results at file output/report.html

Feature

Features with a check mark next to them represent that the feature has already been completed, other features are in development:

• Automatically decide if the input is a web address or an RDP server
• Automatically create output directory if it doesn’t already exist
• Save images with consistent and unique name in server/IP
• Full support for IPv6 and IPv4 characters as well as hostnames
• Read the targets from the file and decide if they are RDP or HTTP or use hints
• Parsing the target intelligently from the results of Nmap and Nessus
• HTTP – use Chromium/Chrome in headless mode
• Cross-platform support – tested on Linux, Windows and Mac
• Generate HTML reports for easy viewing of results
• VNC
• RDP
• Stream video – tracking
• timestamp option in filename
• Read target from msf service -o csv . output
• OCR on RDP username, directly or on the images folder
• NLA/auth to check credentials
• Parse JSON Dirble output to get a screenshot of the entire web page
