Sticky-Keys-Slayer

Scans for accessibility tools backdoors via RDP

stickyKeysSlayer.sh

Establishes a Remote Destop session (RDP) with the specified hosts and sends key presses to launch the accessibility tools within the Windows Login screen. stickyKeysSlayer.sh will analyze the console and alert if a command prompt window opens up. Screenshots will be put into a folder ('./rdp-screenshots' by default) and screenshots with a cmd.exe window are put in a subfolder ('./rdp-screenshots/discovered' by default). stickyKeysSlayer.sh accepts a single host or a list of hosts, delimited by line and works with multiple hosts in parallel.

stickyKeysSlayer.sh incorporates code from Zach Grace's sticky_keys_hunter

Dependencies:

• imagemagick
• xdotool
• parallel
• bc

All packages exist in the Kali repositories:

apt-get update

apt-get -y install imagemagick xdotool parallel bc

Docker:

In some situations, running this tool within Docker may be advantageous. To do so, first build it:

docker build -t sticky-keys-slayer .

Then run the container, passing in necessary arguments to stickyKeysSlayer.sh:

docker run --rm -it --name sticky-keys-slayer --net=host sticky-keys-slayer -o /tmp/pics <target>

If you'd like to save the screenshots of vulnerable systems:

mkdir pics
docker run --rm -it --name sticky-keys-slayer --net=host -v `pwd`/pics:/tmp/foo/ sticky-keys-slayer -o /tmp/pics <target>

If you'd like to pass in a list of hosts to run and save the screenshots

mkdir pics
# put some hosts in hosts.txt
echo 192.168.0.1 > hosts.txt
docker run --rm -it --name sticky-keys-slayer --net=host -v `pwd`/hosts.txt:/tmp/hosts.txt -v `pwd`/pics:/tmp/foo/ sticky-keys-slayer -o /tmp/pics /tmp/hosts.txt

To Do:

• Detection of missed boxes (boxes to which we do not obtain a screenshot)
• Handle scenario when more than one window is found to share the same title. Perhaps quit if wc -l > 1 for xdotool search.
• Detect if black pixels are greater than 480,000. Means title bar went away. Possibly error out and move on
• Fix bug when scanning hosts with a specified port. (Ex: 192.168.0.2:34123)
• Fix whitespacing (Windows vs Linux)
