Domain Enumeration
Current domain name:
PS C:> [System.Net.Dns]::GetHostByName(($env:computerName))
PS C:> [System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()
Domain Forest Trusts
PS C:> ([System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()).GetAllTrustRelationships()
PS C:> ([System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest())
PS C:> ([ADSISearcher]"(objectClass=trustedDomain)").FindAll()
PS C:> ([ADSISearcher]"(objectClass=trustedDomain)").FindAll() | %{$a=$_.Properties["trustattributes"]; $d=$_.Properties["trustdirection"]; $t=$_.Properties["trusttype"] ; write-Host $_.Properties["distinguishedname"] $a $d $t}
Get Password Policy
PS C:> Get-ADDefaultDomainPasswordPolicy -Current LoggedOnUser
Get a Domain Computer
PS C:> ([ADSISearcher]"(&(objectClass=computer)(name=SV-*))").FindAll()
The above one-liner we searched for a computer name starting with “SV-”, that can possibly be a server appellation. Similarly, it is possible to enumerate a specific computer with the exact name.
PS C:> ([ADSISearcher]"(&(objectClass=computer)(name=<COMPUTERNAME>))").FindAll()
Get All Domain Computers
PS C:> ([ADSISearcher]"ObjectClass=computer").FindAll()
Enumerate Single User
PS C:> ([ADSISearcher]"(&(objectClass=user)(samAccountType=805306368)(samaccountname=<USERNAME>))").FindAll().Properties
Enumerate All Domain Controllers
PS C:> ([ADSISearcher]"(&(objectCategory=computer)(userAccountControl:1.2.840.113556.1.4.803:=8192))").FindAll()
Enumerate All Users
PS C:> ([ADSISearcher]"(&(objectClass=user (samAccountType=805306368))").FindAll()|ft
Enumerate All Users With Specific Properties
Filter by property, this code will just display “samaccountname” as a result for all users.
PS C:> ([ADSISearcher]"(&(objectClass=user)(samAccountType=805306368))").FindAll() | %{ $_.Properties["samaccountname"] }
Enumerate all users with a SPN
A service instance’s service principal name (SPN) is a unique identifier. Kerberos authentication uses SPNs to link a service instance to a service login account. This enables a client application to ask the service to authenticate an account even if it doesn’t know the account name. If we want to display all users with SPN then we can use below code:
PS C:> ([ADSISearcher]"(&(objectClass=user)(servicePrincipalName=*)(samAccountType=805306368))").FindAll()
Enumerate a Domain Group
PS C:> ([ADSISearcher]"(&(ObjectClass=group)(samaccountname=Domain Admins))").FindOne()
Enumerate All Domain Groups
PS C:> ([ADSISearcher]"ObjectClass=group").FindAll()
Enumerate domain group members
PS C:> ([ADSISearcher]"(distinguishedname=CN=AB ACCESS,CN=Users,DC=corp,DC=manmeetdc,DC=local)").FindOne().Properties.member
