Accessibility Features (Sticky Keys) Persistence via Debugger Registry Key

This module makes it possible to apply the 'sticky keys' hack to a session with appropriate
rights. The hack provides a means to get a SYSTEM shell using UI-level interaction at an RDP
login screen or via a UAC confirmation dialog. The module modifies the Debug registry setting
for certain executables.

The module options allow for this hack to be applied to:

SETHC (sethc.exe is invoked when SHIFT is pressed 5 times),
UTILMAN (Utilman.exe is invoked by pressing WINDOWS+U),
OSK (osk.exe is invoked by pressing WINDOWS+U, then launching the on-screen keyboard),
DISP (DisplaySwitch.exe is invoked by pressing WINDOWS+P),
NARRATOR (Narrator.exe is invoked by pressing WINDOWS+CTR+ENTER),
ATBROKER (AtBroker.exe is invoked by launching accessibility features from the login screen, such as WINDOWS+CTR+ENTER).

Custom payloads and binaries can be run as part of this exploit, but must be manually uploaded
to the target prior to running the module.
