Powermad - PowerShell MachineAccountQuota and DNS exploit tools
Author: Kevin Robertson (@kevin_robertson)
License: BSD 3-Clause

#region begin MachineAccountQuota Functions
function Disable-MachineAccount
{
<#
.SYNOPSIS
This function disables a machine account that was added through New-MachineAccount. This function should be
used with the same user that created the machine account.
Author: Kevin Robertson (@kevin_robertson)
License: BSD 3-Clause
.DESCRIPTION
Machine accounts added with New-MachineAccount cannot be deleted with an unprivileged user. Although users
can remove systems from a domain that they added using ms-DS-MachineAccountQuota, the machine account in AD is
just left in a disabled state. This function provides that ability by setting the AccountDisabled to true.
Ideally, the account is removed after elevating privilege.
.PARAMETER Credential
PSCredential object that will be used to disable the machine account.
.PARAMETER DistinguishedName
Distinguished name for the computers OU.
.PARAMETER Domain
The targeted domain in DNS format. This parameter is required when using an IP address in the DomainController
parameter.
.PARAMETER DomainController
Domain controller to target. This parameter is mandatory on a non-domain attached system.
.PARAMETER MachineAccount
The username of the machine account that will be disabled.
.EXAMPLE
Disable a machine account named test.
Disable-MachineAccount -MachineAccount test

.SYNOPSIS
This function leverages the ms-DS-CreatorSID property on machine accounts to return a list
of usernames or SIDs and the associated machine account. The ms-DS-CreatorSID property is only
populated when a machine account is created by an unprivileged user. Note that SIDs will be returned
over usernames if SID to username lookups fail through System.Security.Principal.SecurityIdentifier.
.DESCRIPTION
This function can be used to see how close a user is to a ms-DS-MachineAccountQuota before
using New-MachineAccount.

.PARAMETER Credential

.PARAMETER DistinguishedName
Distinguished name for the computers OU.
.PARAMETER Domain
The targeted domain in DNS format. This parameter is required when using an IP address in the DomainController
parameter.
.PARAMETER DomainController
Domain controller to target. This parameter is mandatory on a non-domain attached system.

Get the ms-DS-CreatorSID values for a domain.

function Invoke-AgentSmith

<#
.SYNOPSIS
This function leverages New-MachineAccount to recursively create as as many machine accounts as possible
from a single unprivileged account through MachineAccountQuota. With a default MachineAccountQuota of 10,
the most common result will be 110 accounts. This is due to the transitive quota of Q + Q * 1 where Q
equals the MachineAccountQuota setting. The transitive quota can often be exceeded to the total number of
created accounts can vary. I wouldn't recommend running this one on a client network unless you have a
good reason.

<#
.SYNOPSIS
This function adds a machine account with a specified password to Active Directory through an encrypted LDAP
add request. By default standard domain users can add up to 10 systems to AD (see ms-DS-MachineAccountQuota).
Author: Kevin Robertson (@kevin_robertson)
License: BSD 3-Clause
.DESCRIPTION
The main purpose of this function is to leverage the default ms-DS-MachineAccountQuota attribute setting which
allows all domain users to add up to 10 computers to a domain. The machine account and HOST SPNs are added
directly through an LDAP connection to a domain controller and not by attaching the host system to Active
Directory. This function does not modify the domain attachment and machine account associated with the host
system.
Note that you will not be able to remove the account without elevating privilege. You can however disable the
account as long as you maintain access to the account used to create the machine account.
.PARAMETER Credential
PSCredential object that will be used to create the machine account.
.PARAMETER Domain
The targeted domain in DNS format. This parameter is required when using an IP address in the DomainController
parameter.
.PARAMETER DomainController
Domain controller to target. This parameter is mandatory on a non-domain attached system.
.PARAMETER DistinguishedName
Distinguished name for the computers OU.
.PARAMETER MachineAccount
The machine account that will be added.
.PARAMETER Password
The securestring of the password for the machine account.
.EXAMPLE
Add a machine account named test.
New-MachineAccount -MachineAccount test
.EXAMPLE
Add a machine account named test with a password of Summer2018!.
$machine_account_password = ConvertTo-SecureString 'Summer2018!' -AsPlainText -Force

.SYNOPSIS
This function removes a machine account with a privileged account.

License: BSD 3-Clause
.DESCRIPTION
Machine accounts added with MachineAccountQuote cannot be deleted with an unprivileged user. Although users
can remove systems from a domain that they added using ms-DS-MachineAccountQuota, the machine account in AD is
just left in a disabled state. This function provides the ability to delete a machine account once a
privileged account has been obtained.
.PARAMETER Credential
PSCredential object that will be used to delete the ADIDNS node.
.PARAMETER DistinguishedName
Distinguished name for the ADIDNS node.
.PARAMETER Domain
The targeted domain in DNS format. This parameter is required when using an IP address in the DomainController
parameter.
