Enumeración de NTDS - Parte 1

Si queremos enumerar las politicas que esten establecidas en el equipo WS01 el cual no tiene privilegios de administrador, podremos hacerlo, ya que cargamos el PowerView y seria de la sigueinte forma:

Get-DomainPolicy

Info:

Unicode        : @{Unicode=yes}
SystemAccess   : @{MinimumPasswordAge=1; MaximumPasswordAge=42; MinimumPasswordLength=7; PasswordComplexity=1;
                 PasswordHistorySize=24; LockoutBadCount=0; RequireLogonToChangePassword=0;
                 ForceLogoffWhenHourExpire=0; ClearTextPassword=0; LSAAnonymousNameLookup=0}
KerberosPolicy : @{MaxTicketAge=10; MaxRenewAge=7; MaxServiceAge=600; MaxClockSkew=5; TicketValidateClient=1}
RegistryValues : @{MACHINE\System\CurrentControlSet\Control\Lsa\NoLMHash=System.Object[]}
Version        : @{signature="$CHICAGO$"; Revision=1}
Path           : \\corp.local\sysvol\corp.local\Policies\{31B2F340-016D-11D2-945F-00C04FB984F9}\MACHINE\Microsoft\Windo
                 ws NT\SecEdit\GptTmpl.inf
GPOName        : {31B2F340-016D-11D2-945F-00C04FB984F9}
GPODisplayName : Default Domain Policy

Podremos filtrar para obtener el SystemAccess de la siguiente forma:

(Get-DomainPolicy)."SystemAccess"

Info:

MinimumPasswordAge           : 1
MaximumPasswordAge           : 42
MinimumPasswordLength        : 7
PasswordComplexity           : 1
PasswordHistorySize          : 24
LockoutBadCount              : 0
RequireLogonToChangePassword : 0
ForceLogoffWhenHourExpire    : 0
ClearTextPassword            : 0
LSAAnonymousNameLookup       : 0

Información del DC

Si queremos saber la informacion del DC tanto su IP como demas cosas y no lo queremos hacer con PowerView, lo podremos hacer de forma manual en el equipo WS02 en el que cargamos el .dll anteriormente, si se ha reiniciado la maquina o algo por el estilo habra que volver a cargarlo:

Import-Module .\Microsoft.ActiveDirectory.Management.dll
Get-ADDomainController

Info:

Domain             : corp.local
Forest             : corp.local
Name               : DC01
Site               : Default-First-Site-Name
IPv4Address        : 192.168.5.5
IPv6Address        :
PropertyNames      : {ComputerObjectDN, DefaultPartition, Domain, Enabled...}
AddedProperties    : {}
RemovedProperties  : {}
ModifiedProperties : {}
PropertyCount      : 24

Y con PowerView se podria hacer de la siguiente forma:

Get-NetDomainController

Info:

Forest                     : corp.local
CurrentTime                : 10/01/2025 8:36:46

Domain                     : corp.local
IPAddress                  : 192.168.5.5
SiteName                   : Default-First-Site-Name
SyncFromAllServersCallback :
InboundConnections         : {}
OutboundConnections        : {}
Name                       : DC01.corp.local
Partitions                 : {DC=corp,DC=local, CN=Configuration,DC=corp,DC=local,
                             CN=Schema,CN=Configuration,DC=corp,DC=local, DC=DomainDnsZones,DC=corp,DC=local...}

Al utilizar PowerView genera trafico de red en el cual puede ser detectado por herramientas de seguridad, pero son alertas que nadie va a investigar ya que la alerta suele ser de Bad Trafic y es por que PowerView a veces los paquetes de red van de forma erronea y se genera trafico malo, pero nadie lo va a investigar asi que se puede utilizar las veces que se quiera, pero es para tenerlo en cuenta.

Enumerar usuarios del dominio

Con un usuario normal sin privilegios podremos ser capaces de sacar todos los usuarios del dominio que existen en dicho dominio, primero empezaremos por el modulo de AD:

Desde empleado2 en la consola haremos lo siguiente:

Get-ADUser -Filter *

Info:

RemovedProperties  : {}
ModifiedProperties : {}
PropertyCount      : 10

GivenName          : empleado2

UserPrincipalName  :

PropertyNames      : {DistinguishedName, Enabled, GivenName, Name...}
AddedProperties    : {}
RemovedProperties  : {}
ModifiedProperties : {}
PropertyCount      : 10

Estamos viendo que nos aparece practicamente casi toda la informacion de cada usuario hasta el SamAccountName que es importante el id del nombre de como se tiene que logear en el dominio, etc...

Pero si lo queremos filtrar mas, para que no aparezca tanta info, podremos hacerlo de la siguiente forma:

Get-ADUser -Filter * | select Name,ObjectClass,ObjectGuid

Info:

Name          ObjectClass ObjectGuid
----          ----------- ----------
Administrator user        93c0e554-db8e-41c7-8129-c7e183c05a48
Guest         user        76485e57-831f-4a9a-b5bf-554a50e4e5b6
krbtgt        user        3e5f2afb-8433-4a2b-ad2b-e1f082a1352c
empleado1     user        438f71e8-3e05-4f21-bba7-700dd9a044e1
empleado2     user        5c5b97bc-c7a3-4d27-8291-6b9a4a77e511

Ahora si queremos hacerlo con PowerView podremos hacerlo asi:

Get-NetUser

Enumerar información de los equipos del dominio

Con el modulo de AD podremos sacar los grupos que tenemos en el dominio de la siguiente forma:

Get-ADComputer -Filter *

PropertyCount      : 9

Si lo queremos filtrar por informacion mas relevante:

Get-ADComputer -Filter * | select DNSHostName,SamAccountName,Name

Info:

DNSHostName     SamAccountName Name
-----------     -------------- ----
DC01.corp.local DC01$          DC01
WS01.corp.local WS01$          WS01
WS02.corp.local WS02$          WS02

Podremos hacer esto mismo pero con PowerView de la siguiente forma:

Get-NetComputer

Aqui por lo que vemos, estamos viendo mucha mas informacion, como por ejemplo la version del sistema operativo que tiene cada uno, el sistema operativo de que tipo es, etc.. Informacion que puede venir muy bien de cara al atacante.

Para filtrar un poco haremos esto:

Get-NetComputer | select name,operatingsystemversion

Info:

name operatingsystemversion
---- ----------------------
DC01 10.0 (20348)
WS01 10.0 (19045)
WS02 10.0 (19045)

Para poder identificar si un equipo esta activo o no, PowerView te proporciona una opcion la cual puede ver si esta activo o no con el -Ping de la siguiente forma:

Get-NetComputer -Ping | select name,operatingsystem

Info:

name operatingsystem
---- ---------------
DC01 Windows Server 2022 Standard
WS01 Windows 10 Pro
WS02 Windows 10 Pro
