Scans for accessibility tools backdoors via RDP
Twitter: @DennisMald
Twitter: @notmedic
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

- imagemagick
- xdotool
- parallel
- bc
All packages exist in the Kali repositories:
apt-get update
apt-get -y install imagemagick xdotool parallel bc
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
- 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)
