.SYNOPSIS
Get a list of ALPC Ports that can be opened by a specified token.
.DESCRIPTION
This cmdlet checks for all ALPC ports on the system and tries to determine if one or more specified tokens can connect to them.
If no tokens are specified then the current process token is used. This function searches handles for existing ALPC Port servers as you can't directly open the server object and just connecting might show inconsistent results.
.PARAMETER ProcessIds
Specify a list of process IDs to open for their tokens.
.PARAMETER ProcessNames
Specify a list of process names to open for their tokens.
.PARAMETER ProcessCommandLines
Specify a list of command lines to filter on find for the process tokens.
.PARAMETER Tokens
Specify a list token objects.
.PARAMETER Processes
Specify a list process objects to use for their tokens.
.INPUTS
None
.OUTPUTS
NtObjectManager.AccessCheckResult
.NOTES
For best results run this function as an administrator with SeDebugPrivilege available.
.EXAMPLE
Get-AccessibleAlpcPort
Get all ALPC Ports connectable by the current token.
.EXAMPLE
Get-AccessibleAlpcPort -ProcessIds 1234,5678
Get all ALPC Ports connectable by the process tokens of PIDs 1234 and 5678

Opens an impersonation token from a process or thread using NtImpersonateThread
.DESCRIPTION
This cmdlet opens an impersonation token from a process using NtImpersonateThread. While SeDebugPrivilege
allows you to bypass the security of processes and threads it doesn't mean you can open the primary token.
This cmdlet allows you to get past that by getting a handle to the first thread and then impersonating it,
as long as the thread isn't impersonating something else you'll get back a copy of the primary token.
.PARAMETER ProcessId
A process to open to get the token from.
.PARAMETER ThreadId
A thread to open to get the token from.
.PARAMETER Access
Access rights for the opened token.
