function Invoke-TokenManipulation
{
<#
.SYNOPSIS
This script requires Administrator privileges. It can enumerate the Logon Tokens available and use them to create new processes. This allows you to use
anothers users credentials over the network by creating a process with their logon token. This will work even with Windows 8.1 LSASS protections.
This functionality is very similar to the incognito tool (with some differences, and different use goals).
This script can also make the PowerShell thread impersonate another users Logon Token. Unfortunately this doesn't work well, because PowerShell
creates new threads to do things, and those threads will use the Primary token of the PowerShell process (your original token) and not the token
that one thread is impersonating. Because of this, you cannot use thread impersonation to impersonate a user and then use PowerShell remoting to connect
to another server as that user (it will authenticate using the primary token of the process, which is your original logon token).
Because of this limitation, the recommended way to use this script is to use CreateProcess to create a new PowerShell process with another users Logon
Token, and then use this process to pivot. This works because the entire process is created using the other users Logon Token, so it will use their
credentials for the authentication.
IMPORTANT: If you are creating a process, by default this script will modify the ACL of the current users desktop to allow full control to "Everyone".
This is done so that the UI of the process is shown. If you do not need the UI, use the -NoUI flag to prevent the ACL from being modified. This ACL
is not permenant, as in, when the current logs off the ACL is cleared. It is still preferrable to not modify things unless they need to be modified though,
so I created the NoUI flag. ALSO: When creating a process, the script will request SeSecurityPrivilege so it can enumerate and modify the ACL of the desktop.
This could show up in logs depending on the level of monitoring.
PERMISSIONS REQUIRED:
SeSecurityPrivilege: Needed if launching a process with a UI that needs to be rendered. Using the -NoUI flag blocks this.
SeAssignPrimaryTokenPrivilege : Needed if launching a process while the script is running in Session 0.
Important differences from incognito:
First of all, you should probably read the incognito white paper to understand what incognito does. If you use incognito, you'll notice it differentiates
between "Impersonation" and "Delegation" tokens. This is because incognito can be used in situations where you get remote code execution against a service
which has threads impersonating multiple users. Incognito can enumerate all tokens available to the service process, and impersonate them (which might allow
you to elevate privileges). This script must be run as administrator, and because you are already an administrator, the primary use of this script is for pivoting
without dumping credentials.
In this situation, Impersonation vs Delegation does not matter because an administrator can turn any token in to a primary token (delegation rights). What does
matter is the logon type used to create the logon token. If a user connects using Network Logon (aka type 3 logon), the computer will not have any credentials for
the user. Since the computer has no credentials associated with the token, it will not be possible to authenticate off-box with the token. All other logon types
should have credentials associated with them (such as Interactive logon, Service logon, Remote interactive logon, etc). Therefore, this script looks
for tokens which were created with desirable logon tokens (and only displays them by default).
In a nutshell, instead of worrying about "delegation vs impersonation" tokens, you should worry about NetworkLogon (bad) vs Non-NetworkLogon (good).

Required Dependencies: None
Optional Dependencies: None
.DESCRIPTION
Lists available logon tokens. Creates processes with other users logon tokens, and impersonates logon tokens in the current thread.
.PARAMETER Enumerate
Switch. Specifics to enumerate logon tokens available. By default this will only list unqiue usable tokens (not network-logon tokens).
.PARAMETER RevToSelf
Switch. Stops impersonating an alternate users Token.
.PARAMETER ShowAll
Switch. Enumerate all Logon Tokens (including non-unique tokens and NetworkLogon tokens).
.PARAMETER ImpersonateUser
Switch. Will impersonate an alternate users logon token in the PowerShell thread. Can specify the token to use by Username, ProcessId, or ThreadId.
This mode is not recommended because PowerShell is heavily threaded and many actions won't be done in the current thread. Use CreateProcess instead.
.PARAMETER CreateProcess
Specify a process to create with an alternate users logon token. Can specify the token to use by Username, ProcessId, or ThreadId.
.PARAMETER WhoAmI
Switch. Displays the credentials the PowerShell thread is running under.
.PARAMETER Username
Specify the Token to use by username. This will choose a non-NetworkLogon token belonging to the user.
.PARAMETER ProcessId
Specify the Token to use by ProcessId. This will use the primary token of the process specified.
.PARAMETER Process
Specify the token to use by process object (will use the processId under the covers). This will impersonate the primary token of the process.
.PARAMETER ThreadId
Specify the Token to use by ThreadId. This will use the token of the thread specified.
.PARAMETER ProcessArgs
Specify the arguments to start the specified process with when using the -CreateProcess mode.
.PARAMETER NoUI
If you are creating a process which doesn't need a UI to be rendered, use this flag. This will prevent the script from modifying the Desktop ACL's of the
current user. If this flag isn't set and -CreateProcess is used, this script will modify the ACL's of the current users desktop to allow full control
to "Everyone".
.PARAMETER PassThru
If you are creating a process, this will pass the System.Diagnostics.Process object to the pipeline.
.EXAMPLE
Invoke-TokenManipulation -Enumerate
Lists all unique usable tokens on the computer.
.EXAMPLE
Invoke-TokenManipulation -CreateProcess "cmd.exe" -Username "nt authority\system"
Spawns cmd.exe as SYSTEM.
.EXAMPLE
Invoke-TokenManipulation -ImpersonateUser -Username "nt authority\system"
Makes the current PowerShell thread impersonate SYSTEM.
.EXAMPLE
Invoke-TokenManipulation -CreateProcess "cmd.exe" -ProcessId 500
Spawns cmd.exe using the primary token belonging to process ID 500.
.EXAMPLE
Invoke-TokenManipulation -ShowAll
Lists all tokens available on the computer, including non-unique tokens and tokens created using NetworkLogon.
.EXAMPLE
Invoke-TokenManipulation -CreateProcess "cmd.exe" -ThreadId 500
Spawns cmd.exe using the token belonging to thread ID 500.
.EXAMPLE
Get-Process wininit | Invoke-TokenManipulation -CreateProcess "cmd.exe"
Spawns cmd.exe using the primary token of LSASS.exe. This pipes the output of Get-Process to the "-Process" parameter of the script.
.EXAMPLE
(Get-Process wininit | Invoke-TokenManipulation -CreateProcess "cmd.exe" -PassThru).WaitForExit()
Spawns cmd.exe using the primary token of LSASS.exe. Then holds the spawning PowerShell session until that process has exited.
.EXAMPLE
Get-Process wininit | Invoke-TokenManipulation -ImpersonateUser
Makes the current thread impersonate the lsass security token.
