| .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. | |
